Chapter XXXI: Part 31

A very significant feature of the age has been the extraordinary development of associations devoted to scientific discussions and the publication of medical literature and journals. The formation of medical societies, especially in the United States, has been quite active. But few counties are without a medical organization, referred to as “The ... County Medical Society.”

The American Medical Association was established by Dr. Nathan Smith Davis in Philadelphia fifty-two years ago (1847). The first two years no meetings were held, but since then regular annual meetings have been in progress, the place of assembly being decided upon by a majority vote of its members. It has met in the city of its birth five times, the founder has been elected president twice, and is still (1900) in active practice at the age of eighty-two. He has attended all its meetings held in various cities from Boston to San Francisco.

The first medical journal in this country appeared in New York, 1797. It was called “The New York Repository,” was published quarterly, and managed to reach its twenty-third edition. Fifty years ago there were about twenty journals published in the United States. At the end of the century there are two hundred and thirty.

In 1810 there were six hundred and fifty students of medicine in America, and one hundred graduates. At the present writing about twenty thousand medical students are enrolled in our various colleges, and during the spring of 1899 about three thousand five hundred received the degree of M. D.

The original branches, practice of medicine, surgery, obstetrics, physiology, anatomy, therapeutics, and chemistry, have been subdivided and specialized. Among the chief of these specialties are gynecology, which treats of diseases of women; pediatrics, which treats of diseases of children; dermatology, which treats of diseases of the skin; ophthalmology, which treats of diseases of the eye; laryngology, which treats of diseases of the throat and larynx; otology, which treats of diseases of the ear; neurology, which treats of diseases of the nerves; medical jurisprudence, which treats of the relation of medicine to law; pathology, which treats of diseased tissues and organs; bacteriology, which treats of the microbes; and physical diagnosis, which treats of the art of discriminating disease by means of the eye, ear, and touch. The nucleus of the teaching regarding the latter subject is due to the efforts and observations of Corvisart, of France. He was the first to ascertain the diseased areas of the lungs, by tapping on the chest with the fingers, and listening to the pitch of the note thus elicited. A low, dull note indicates that the lung is solid, as in pneumonia; a flat note that fluid is present, and so on. By placing the ear to the chest wall, sounds in health and disease are heard, which vary in intensity, degree, etc. Laennec discovered by accident that this method was greatly improved and the sounds more distinctly heard if a cylindrical tube was interposed between the ear and the chest wall. The outcome of this principle is the stethoscope.

The name of Pravaz, the Lyons surgeon, has been perpetuated by the hypodermic syringe which he devised. The employment of suitable drugs in this instrument is the method par excellence for relieving pain. With it drugs can be injected into unconscious patients. Suicides who refuse to swallow emetics can have their stomachs emptied most effectually of their contents by a hypodermatic injection of apomorphine.

The thermometer used for taking the temperature of the human body is so arranged that the mercury does not descend into the bulb until shaken down, hence after taking the temperature it remains uninfluenced until shaken down. Were an ordinary thermometer used, by the time it was removed from the patient to the light the mercury would descend several degrees.

Pasteur began the studies of fermentation in 1854. Through his observations, aided by the microscope, the opinion was reached that micro-organisms played an important role in the causation of disease. Many of the laboratory investigators became imbued with the spirit, and through their diligent observations the microbes causing many diseases have been isolated. It remained for Koch to discover the tubercle bacillus, or _Bacillus tuberculosis_, which is the cause of consumption. The sputum of a patient, properly stained, and examined under the microscope, will at once decide whether that individual has consumption.

Having ascertained that bacteria were the cause of disease, sepsis (blood poisoning), etc., it then remained to discover a method of killing them, without any undue injury to the patient. Sir Joseph Lister began experiments upon this hypothesis, and in 1867 was able to publish favorable results. But lo! the world was slow to bend to a new thought ably demonstrated, and for a score of years he was bitterly opposed.

It was Crawford W. Long, in a little village of Alabama, who, in 1842, was the first to put to sleep a patient with ether, and remove a small growth. The patient, upon awakening, had experienced no pain. This method of relieving pain was christened “anæsthesia” several years later, by the distinguished Dr. Oliver Wendell Holmes, whose writings did more than those of any other American to eradicate “child-bed fever.” Every woman in the land owes him an eternal debt of gratitude. To Guthrie, of Sackett’s Harbor, New York, is due the credit of first discovering chloroform, but Sir James Simpson, of Edinburgh, deserves the credit of first employing it in medicine.

The surgeons of America laid the foundation of gynecology, the progress of which has been more marked than any department of medicine. The first ovariotomy in the world was performed by Dr. Ephraim McDowell in Kentucky, December, 1809. This was prior to the days of anæsthesia and antisepsis, and a howling mob awaited outside, ready to murder the brave surgeon should his patient die during the operation. “In five days,” says Dr. McDowell, “I visited her, and much to my astonishment found her engaged in making up her bed.” Dr. J. Marion Sims, our illustrious genius who established an international reputation, did much to promulgate plastic work on the female genitalia. The deeds of medical men are soon forgotten by an ungrateful public, and the sons of Æsculapius are the last to have monuments erected to their memory. But four exist in America; one, in New York, to that grand old gynecologist, Dr. J. Marion Sims; one in Washington, to Dr. Samuel D. Gross, “the Nestor of American Surgery;” one in Bushnell Park, Hartford, Conn., to Dr. Horace Wells, the discoverer of anæsthesia; and one in the Public Garden in Boston to the discoverer of anæsthesia. This last bears no name. Antisepsis and anæsthesia have played an unusually important role in obstetrics, by alleviating the sufferings of childbirth and eradicating child-bed fever, thus reducing the mortality of both mother and child.

Physiology has made very rapid strides during this era. Beaumont, in his famous work, describes digestion in the stomach and experiments on the gastric juice. He was enabled to observe this in a voyageur who was accidentally wounded in the stomach by the discharge of a musket, June, 1822. Quite a large opening remained, which Nature closed with a valve. By pushing the valve to one side, the interior of the stomach could be explored.

Through the work of the experimental physiologists in the laboratories, the study of the action of drugs on the lungs, heart, liver, stomach, nerves, etc., has been greatly enhanced.

Anatomy is now being taught by the only true method, and that is dissection. Didactic lectures are given, but the student must dissect every part of the human body before he can receive his degree. Formerly graves were robbed, and the bodies sold to the colleges. Now, however, through legislative enactment, unclaimed bodies are turned over to the colleges, where they are preserved either by injection, a pickling process, or by cold storage.

The ophthalmologists of to-day fear nothing inside nor outside the eye. Cross eyes are straightened, cataracts removed, eyeballs taken out and glass eyes inserted.

This article would be incomplete, were not a few remarks directed toward the trained nurse.

The first training school for nurses in America was established in connection with the Lying-in Charity Hospital of Philadelphia in 1828. This school, still in existence, thus has the honor of being the oldest in this country, and is antedated by only one abroad.

The generally recognized profession for women, that of the trained nurse, is practically of recent development. Twenty-five years ago the training school connected with the Bellevue Hospital, New York, graduated a class of five nurses. This was a marked departure in the medical history of this country. Since then the demand for the trained nurse has been great, and no hospital is complete without such a training school.

The progress of medicine in the nineteenth century has been far more rapid, creditable, and momentous than during any like period of the past. This is true not only in the United States, but in every civilized country. Its entire scope, meaning, and purpose have undergone changes equivalent to revolution. Antique superstitions, idle theories, foolish speculations, absurd practices, the ridiculous jealousies and incriminations of opposing schools, have been largely eliminated. Medical institutions are upon the loftiest plane in their history. Teachers are better endowed than ever before. Periods of scholastic preparation have been lengthened and curriculums enlarged, thus securing for the fields of practice a higher mental equipment and more conscionable devotion to duty. Never before have the auxiliary and material agencies been turned to so frequent and preventive account. Electricity, the microscope, anæsthesia, antisepsis, laboratory experiment, hospital opportunities, etc., are ever constant inspirations to skilled treatment and fresh researches. As the grand army of humanitarian workers was never so large as at the end of the century, so it was never better fortified for attack upon the enemies of health, fuller of enthusiasm or more deeply established in the public confidence. One may not, as yet, assert that medicine is ridding itself of empiricism with a satisfactory degree of rapidity, or that it has arrived at the stage of an exact science, but it surely has approached such a stage as nearly as conditions will allow.

EVOLUTION OF THE RAILWAY

BY E. E. RUSSELL TRATMAN, C.E.,

_Assistant Editor of “Engineering News,” Chicago_.

The railway as a means of rapid transportation and general intercommunication is one of the most important factors in the development of modern commerce and civilization, and, after reviewing what it has done and become in the nineteenth century, one cannot help wishing for the opportunity to review the railway wonders of the twentieth century.

While the history of the railway dates back far beyond the nineteenth century, yet the railway, as we know it to-day, is essentially a product of this century. It dates, in fact, from England in 1830, when the Liverpool & Manchester Railway, 31 miles long, was opened, and was operated from the beginning by steam locomotives. The Stockton & Darlington Railway, 37 miles, was opened in 1825, but this line was intended only for private coal traffic, while the other line was built for general passenger and freight service, and for the use and benefit of the public.

The United States followed this lead very closely. In 1828 the Delaware & Hudson Canal Company built a line from its mines to its canal at Honesdale. This was a private coal road, however, and may best be compared to the Stockton & Darlington Railway. The first public railway operated by steam was the Mohawk & Hudson Railway, from Albany to Schenectady, 16 miles, which was opened in 1831. The Baltimore & Ohio Railway was the first railway enterprise of more than local character, being designed to open communication with the Ohio River, a distance of 400 miles. It was chartered in 1827, commenced in 1828, completed to Ellicott’s Mills (13 miles) in 1830, and to Washington (40 miles) in 1834. It is one of the great monuments of the American railway system, and it was examined by government commissions from Russia and Austria in 1831 and 1849.

In speaking of the railway we unconsciously associate with it the steam locomotive, since the two are so entirely interdependent. Railways operated by horses, or by cables and stationary engines, could never have become the great civilizing and commercial medium which the railway operated by swift locomotives has become. Similarly, the development of the locomotive grew apace, as soon as it was recognized that the smooth track of the railway—and not the rough track of the highway—was to be its field of operation.

At the end of the nineteenth century, after seventy years of development, the world has nearly 500,000 miles of railway, on which locomotives of 80 to 110 tons in weight (without their tenders) haul freight trains of 1000 to 3000 tons. Passenger trains, too, are run at speeds of 40 to 75 miles per hour in regular daily service, and even make bursts of speed at 80 to 100 miles per hour. The fact that in 1890 Europe and North America had about 320,000 miles of railway out of a grand total of 370,000 miles, indicates that this phase of nineteenth-century progress has been due mainly to peoples of Christian civilization, and besides this, it must be remembered that the railways of Asia, Africa, Australia, and South America have been mainly built by the same peoples. The central regions of these four latter geographical divisions are fields for twentieth-century development.

The great trunk lines of railway communication are hardly more important than the vast network of branch and minor lines which connect and intersect them. These latter lines bring the people of smaller towns and country districts into closer relation with the large cities, the centres of industrial and intellectual energy, enterprise, and wealth. They thus tend to reduce isolation and dependence upon purely local resources.

Railways also serve important military and strategic purposes. In India many of the railways have been built with a view to the defense of the northeastern frontier, and many European governments assume certain military authority over the railways. The first trans-continental railways of the United States and Canada were largely assisted by government subsidies on account of their great importance for the transportation of troops. The railway also serves purposes of pleasure, as well as of commerce and war. Not only do the ordinary railways carry much tourist and pleasure travel, but lines are built exclusively for such travel. Some of these take people to the summer and pleasure resorts, while others cater to the inherent desire of man to ascend great altitudes and to behold the world in its beauty and grandeur spread below them. For this purpose alone have railways been built to the summits of the Rockies, the Alps, and other mountain ranges.

At the end of the century the United States has about 185,000 miles of railway, which have cost about $53,000 per mile and earn $6500 per mile. Great Britain has about 22,000 miles, which have cost $225,000 per mile and earn about $20,000 per mile. A large proportion of this high cost of construction is due to the high prices for land and to the preliminary parliamentary proceedings which are necessary in securing the right to build railways. The average cost per mile of railways in different countries is as follows:—

United States $53,000
India 75,000
Japan 92,000
France 100,000
Germany 101,500
Switzerland (ordinary) $119,300
Do (mountain) 162,500
Russia 122,000
Austria-Hungary 125,400
Great Britain 225,000

One of the great economic purposes of railways in new countries is to reduce the cost of rapid transportation in bulk far below that of slow transportation in small quantities. Train speed is a matter of secondary importance in such cases, the traffic accommodation and capacity of the slowest train being far beyond that of road or canal transportation. Traffic will be served better and at much less cost by being carried in bulk on 500 miles of railway at 10 miles per hour, than on 100 miles of railway at 35 miles per hour, and then in small lots on wagons or canal boats at 3 miles per hour for 400 miles.

The advantages of the rapid transportation of perishable freight by rail, especially in regard to food supplies for cities, were early recognized, and by 1854 the trains brought car-loads of country milk into London every day. Previous to this, the supply was obtained from cows kept in stables, which was an unsanitary and expensive plan. Another immediate result of railway service was that people began to live farther out of the towns, and then began the growth of the suburban residence districts, which are such a feature of modern cities and city life.

The early railways were built merely as local lines, and there was little idea of their ultimate connection or extension. These small individual lines, however, with their own rate-making powers and systems of management, have been consolidated into great systems, thus effecting material economies and facilities in operation. Thus the Mohawk & Hudson Railway of 1831 was the first of a series of lines now consolidated to form the New York Central Railway; while the Liverpool & Manchester Railway of 1830 was the beginning of what is now the London & Northwestern Railway system. Not only is there this consolidation, but also a most comprehensive system for the interchange of traffic between different systems. Thus passengers can purchase through tickets and travel through from Paris to St. Petersburg, or from Boston to San Francisco, while freight cars can be sent through in a similar way. This is really a wonderful feature of railway development. The following are a few examples of the great railway systems of the world:—

-------------------------------------+------+--------+---------+------- Railway. |Miles.| Loco- |Passenger|Freight | |motives.| Cars. | Cars. -------------------------------------+------+--------+---------+------- Pennsylvania (U.S.A.) | 8882 | 3594 | 3847 |146,060 Chicago & Northwestern (U.S.A.) | 7996 | 1380 | 1176 | 49,484 Chicago, Burlington & Quincy (U.S.A.)| 7462 | 1205 | 936 | 40,720 Atchison, Topeka & Santa Fé (U.S.A.) | 7120 | 1036 | 655 | 29,837 Great Western (England) | 2576 | 1837 | 6201 | 53,156 London & Northwestern (England) | 1912 | 2851 | 8446 | 65,456 Paris, Lyons & Mediterranean (France)| 5594 | 2624 | 5837 | 87,320 Western (France) | 3464 | 1492 | 4378 | 26,487 Mediterranean (Italy) | 3568 | 1314 | 3706 | 23,077 Northwestern (India) | 3371 | 602 | 2121 | 10,312 -------------------------------------+------+--------+---------+-------

In some countries the government owns and operates all, or nearly all, of the railways, as in Germany, Belgium, and the African and Australian colonies. Switzerland, in 1898, decided that its government should acquire the railways. In Holland and Italy the government owns the railways, but leases them to operating companies. France, Brazil, and the Argentine Republic have both state and private lines, with a greater or less degree of state assistance and control of the latter. In Great Britain the railways are owned entirely by private companies, but their operation is subject to government supervision in the public interests. In the United States there was at first almost absolute freedom of construction, but the consequent abuses and financial disasters, owing to unnecessary lines and cut-throat competition, have led some of the States to wisely exercise some degree of control over railway affairs. The interference of the federal government in railway affairs has been slight but important. In 1862 it aided the construction of the first transcontinental railway; in 1887 it passed the act for the regulation of rates, etc., in interstate traffic; and in 1893 it passed the act making compulsory the use of power brakes and automatic couplers on freight cars.

Government ownership and operation of railways is rarely satisfactory from a financial or a traffic point of view, but, on the other hand, an absolutely unrestricted railway element is liable to become a serious evil. The best system is undoubtedly that in which the railways are owned and operated by private enterprise, but subject to state supervision, like steamships, factories, etc. It must not be forgotten, however, that private enterprise is not always available. In Russia, for example, the development of railways would have been but slow on such a basis; and in India, government backing was needed to induce British capitalists to enter the field. It is unfortunate for China that neither the government nor the people have been competent or enterprising enough to deal with the railway question. The present system of development by rival interests of various nationalities seems almost certain to lead to the eventual dissolution of the empire and its partition among other nations, as Africa is already in large measure partitioned.

In the United States railway construction has gone by leaps and bounds, and there is now a vast network of lines,—main, secondary, branch, and local. The highest records of construction within the past twenty years were 12,800 miles built in 1887, and 11,600 miles in 1882, while the lowest record was 1750 miles in 1896. The growth from 1886 to 1899 has been as follows, the relatively small increase in number of locomotives being due to the greater power of modern engines:—

---------------------+-------------+--------------+----------
| | | Increase,
| 1886. | 1899. | per cent.
---------------------+-------------+--------------+----------
Mileage | 133,600 | 185,000 | 88.47
Tonnage carried |482,000,000 | 780,000,000 | 62.00
Number of cars | 871,500 | 1,330,000 | 52.61
Number of locomotives| 26,400 | 36,000 | 36.30
---------------------+-------------+--------------+----------

Perhaps the railway of most recent interest is the first line in Alaska, which is twenty miles long, and was built as a result of the rush to the Klondike gold fields. This was opened on February 20, 1899. The great transcontinental railways, however, are of much broader interest. In 1835 the Rev. Samuel Parker, a missionary in the Northwest, suggested a railway from the Atlantic to the Pacific, and Dr. Samuel E. Barlow proposed one from New York to the Columbia River, 2000 miles, to cost $10,000 per mile, and to carry traffic at about seven miles per hour. From 1844 to 1849 Mr. Asa Whitney urged Congress to grant land to aid him in building a line from Lake Michigan to San Francisco, 2030 miles, to cost $20,000 per mile. Between 1853 and 1861 Congress had surveys made of five routes, but no definite action was taken until after the outbreak of the Civil War, in 1861, when the federal government soon recognized the importance of having direct communication with the Pacific States, which were at that time isolated. Companies were organized in 1862, and work commenced in 1864, under government subsidies and military aid and protection. On May 10, 1869, the Union Pacific Railway (from the east) and the Central Pacific Railway (from the west) met at Promontory Point, Utah, 1186 miles from the Missouri River and 638 miles from Sacramento, Cal.

Now, thirty years later, we have six so-called transcontinental railways, no one of which, however, has its own line from ocean to ocean, and none of which run through trains or cars. In Canada, however, the Canadian Pacific Railway (opened in 1887) has a through line from St. John and Montreal to Vancouver, with through trains daily between the latter points, 2905 miles. The principal transcontinental lines, with the total distances from ocean to ocean, are shown on the following page.

-------------------+-------+------------------------+-------+---------

-------------------+-------+------------------------+-------+---------

[6] In Nos. 2 and 7 the total distance is given from New York.

Of the various completed and partly completed interoceanic railways across Central America, the most important by far is the Panama railway, in Colombia, 47½ miles long. This was opened as long ago as 1855, and was originally intended as a link in a route between New York and San Francisco, 5450 miles. In South America there are few railways of great importance, and the interior yet remains undeveloped, with the exception of the great plains of the Argentine Republic. A transcontinental line between Buenos Ayres and Valparaiso, 850 miles, is nearly completed, but work has been stopped for some years, leaving 50 miles yet to be built at the summit of the Andes. An interesting, but as yet visionary, scheme is that for an intercontinental railway through Central and South America. The distance from the southern frontier of Mexico to Buenos Ayres would be 5500 miles. About 1280 miles of this are built, but comprise many small lines which would have to be rebuilt. The total cost would be about $220,000,000, at a low estimate, and the total distance from New York to Buenos Ayres would be 10,300 miles by rail.

In Europe there is a vast and comprehensive network of railway lines, but the distances are less, even St. Petersburg and Constantinople being but about 1600 and 1800 miles from Paris. While the development of railways has been remarkable, the most striking features are the lines which cross the Alps to connect the interior with the Mediterranean ports. The first of these was the Semmering railway, on the route between Vienna and Trieste (1854). The Mont Cenis railway (1867) was mainly a surface line, with heavy inclines operated on the Fell grip-rail system. Its route followed the great carriage road built by Napoleon in 1803–10. The railway over the Brenner Pass was opened in 1868; in 1871 the Mont Cenis tunnel superseded the high-level line, and in 1880 the Great St. Gothard railway was opened. This was followed by the Arlberg railway in 1884, and the Simplon railway is now under construction.

Europe has the only railway within the Arctic Circle. It runs from Lulea, on the Gulf of Bothnia, northwest to the Gellivara iron mines, 44 miles within the circle. As the port is closed by ice during the winter, the line is to be extended to the Atlantic coast at Ofoten, 69° north latitude, where the influence of the Gulf Stream keeps the ports open. This end of the line will be 130 miles north of the Arctic Circle.

The countries of Asia (with the exception of India) are but scantily supplied with railways. Even Palestine—the Holy Land—has, however, been invaded, and has now two railways. One of these is from Jaffa (the biblical Joppa) to Jerusalem, 54 miles (1892); the other is from Beirut to Damascus, 70 miles. British interests have long advocated an “all-rail-to-India” project. The line would start opposite Constantinople, pass down the Euphrates valley, across Persia, and along the coast of Baluchistan to Kurrachee, connecting there with the Indian railway system. This great system aggregates 25,000 miles, and extends up to the Bolan Pass and the Khyber Pass, on the Afghan frontier. Southward, it has been proposed to connect with the Ceylon railways by a line of bridges and embankments along the reefs and shoals known as Adam’s Bridge.

Owing to the vigorous opposition of the government and people, China has but 350 miles of railway to its 4,200,000 square miles and its population of 420,000,000. Many lines are projected, but are all in the eastern portion, and the twentieth century will be well advanced before the railway opens up the heart of the country to civilization. Japan, the very opposite of China, has encouraged railway construction, and now has 3000 miles of railway to its 147,600 square miles and its population of 45,000,000.

The most notable of all the railways in Asia is the great Trans-Siberian railway, now being built by the Russian government. It was commenced in 1891, and may be completed by 1903, the distance from St. Petersburg to Vladivostok, or Port Arthur, being then about 5670 miles. There are several large cities on the route, and the line does not pass through such a wild and uninhabited country as that through which the Union Pacific Railroad was built thirty years ago. It is now open to Lake Baikal, the trip of 3230 miles being made in about 12 days by the slow train, or 8 days by the less frequent fast train. The road is roughly and lightly built in many respects, so that high speeds cannot be maintained. The eastern end of the road will pass through Chinese territory, thus giving Russia a firm foothold in that empire. Hardly less interesting is the Trans-Caspian railway, from the Caspian Sea to Samarcand, 885 miles, with a branch from Merv to within 95 miles of the Afghan city of Herat. An extension to the Persian Gulf is also projected. As the Trans-Siberian railway has developed a new wheat-growing region, so the Trans-Caspian railway is developing a new cotton-growing region.

In Africa the railways already extend northward from Cape Town, through the land of the Boers and up to Buluwayo, the old Zulu stronghold, 1400 miles. There is a picturesque project for carrying the line on to the Mediterranean, a total distance of 5500 miles, but this will not materialize for many years. The Congo railway, passing the rapids, opens communication between the coast and a long stretch of inland navigation. Several lines are being pushed from the east coast into the interior, and a transcontinental railway from St. Paul de Loando, on the west, has been commenced, but there is not now much life in this latter project. The French have two favorite schemes for railways,—from Algeria to Timbuctoo, and from Tunis to Lake Chad, the latter line being about 1600 miles in length.

In Australia, the lines of the different colonies are gradually extending and connecting to form a continuous system, which is hampered, however, by differences of gauge. There is railway communication between the capitals of Queensland (Brisbane), New South Wales (Sydney), Victoria (Melbourne), and South Australia (Adelaide). The great stretch westward to the coast cities of Western Australia is yet in the future, as is also the South Australian transcontinental line from Adelaide northward across vast deserts (already crossed by the telegraph) to Palmerston.

Great bridges and tunnels are among the prominent features of the railways of the world, but space forbids entering into details of these works. They are in principle similar to those required for highways, but many of these great works would never have been undertaken for such traffic as is carried by a highway. The only railway suspension bridge ever built was the Niagara bridge, opened in 1855, and replaced by a steel arch in 1898. The development of bridges and traffic may be judged from the fact that the Victoria single-track tubular bridge over the St. Lawrence, at Montreal, which was opened in 1859, was replaced in 1897–98 by a double-track railway and roadway truss bridge on the same piers. The steel arch bridge, 1700 feet long, across the Mississippi, at St. Louis, cost $5,300,000. The tubular bridge, 6592 feet long, over the St. Lawrence, at Montreal, Canada, cost $7,000,000. The cantilever bridge, 8925 feet long, over the Firth of Forth, Great Britain, cost $13,000,000. The cost of the proposed suspension bridge, 3000 feet long, over the Hudson, at New York, is estimated at $13,000,000. The first railway tunnel was the Portage Tunnel, in Pennsylvania, built in 1831. The longest railway tunnel is the Simplon, in Switzerland. It is 12.25 miles in length, and is still under construction. The next longest is the Gothard, Switzerland. It is 9.30 miles long, and was opened in 1881.

In track construction, cast-iron rails began to be superseded by wrought iron in 1820, and many of the early American railways had strap iron laid on timber stringers. Within the past twenty years steel has been used almost exclusively. In place of rails weighing 25 to 35 lbs. per yard, and 3 to 15 feet in length, we now use rails of 80 to 100 lbs. per yard, 30 to 60 feet long. Stone blocks and wooden ties were first used to support the rails, and the latter are now generally used, although metal ties are extensively used and date back to 1846. In 1894 there were thirty-five thousand miles of railway laid with this form of track. The next development will probably be a permanent and continuous concrete bed for the rails; as the present construction, with wooden ties laid in stone or other ballast, requires continual attention and repair under the effects of heavy traffic.

The semaphore signal was introduced in England by Mr. C. H. Gregory in 1841, and is now used in all parts of the world, to govern and protect train movements. The first interlocking plant was erected in 1843, and the complete plants—as used to-day—date from 1856. Now, practically all important junctions are equipped with interlocking plants, which prevent conflicting signals and switches being so set as to lead to accident. The electric telegraph was patented by Cooke and Wheatstone in 1837, and in 1839 they secured its introduction to govern the train service on the Great Western Railway (England). The movements were telegraphed from station to station, and a train was not allowed to leave a station until the preceding train had passed the next station in advance. This was the beginning of the “block system,” which is a great element in the safe operation of traffic, since it maintains an interval of space between trains. Mr. Edwin Clark’s telegraph block system was introduced in 1853, and as traffic increased intermediate block signal stations were established between the regular stations, so as to shorten the distances between trains. This system is compulsory in Great Britain and is already largely used in the United States. It was at first held that it was not adapted to conditions in this country, where so many lines have but a single track, but experience has shown that it increases the facility as well as the safety of operating traffic on single and double track lines alike.

Steam locomotives were used on colliery railways in England as early as 1804, when Trevithick built an engine, which was the first to haul a train on rails. George Stephenson built his first locomotive in 1814, and in 1825 built the “Locomotion” for the Stockton & Darlington Railway. Horses, stationary engines, and steam locomotives were all proposed for the Liverpool & Manchester Railway, and in 1829 the directors offered a premium of $2500 for the best locomotive. Each engine was to consume its smoke, weigh about 6 tons, cost not more than $2750, and be capable of hauling a train of 20 tons at 10 miles per hour. This led to the now historical trials at Rainhill, in October, 1829, between the “Rocket” (Stephenson), the “Novelty” (Braithwaite and Ericson), and the “Sans Pareil” (Hackworth). The award was made to the “Rocket” as the most practicable machine, although the “Novelty” attained a higher speed, and the “Sans Pareil” was also a good engine and continued in use for several years. Seguin introduced the locomotive in France in 1827, having modified and rebuilt an old Stephenson engine.

The first locomotive operated in the United States was the imported “Stourbridge Lion,” on the Delaware & Hudson Canal Co.’s line, in 1829. Cooper’s “Tom Thumb” was run on the Baltimore & Ohio Railway in 1830, and in 1831 the directors of this road offered premiums of $4000 and $3500 for locomotives. Each engine was to weigh not more than 3½ tons, to have four wheels, and to haul loads of 15 tons at 15 miles per hour for 30 days. Five engines were presented, by Davis, Costell, Milholland, Childs, and James. The prizes were awarded to the first two, the Davis engine “York” being rebuilt under the direction of its inventor and Mr. Ross Winans, while the “Costell” was put in switching service. In 1831 the “John Bull” was built by the Stephensons in England, and was put in service on the Camden & Amboy Railway (U. S. A.) in the same year. In 1893 this old engine was readjusted and ran from New York to Chicago, 912 miles, under its own steam, hauling two cars of the type of 1836.

In 1898 there were about 19,500 locomotives in Great Britain and 36,500 in the United States. As a comparison between the little engines of early days and the huge and swift engines of to-day, it may be stated that modern passenger locomotives are now constructed with as many as six driving wheels, and ten wheels in all. Some of those in use on the Great Northern Railway, Great Britain, have driving wheels of 97 inches in diameter. On the Fitchburg Railway, U. S. A., locomotives are in use which weigh 75 tons. Some modern freight locomotives have as many as ten driving wheels, and twelve wheels in all, and a total weight of 115 tons.

Since the application of electric traction to street railways, it has frequently been said that it would eventually supersede the steam locomotive. In no instance, however, has it yet been applied to regular railway service, with heavy trains and long runs, nor is there yet any indication of increased economy or efficiency due to its use in such service. It is successfully used for local and suburban lines, but these form a class in themselves, and the conditions of operation are very different from those which obtain in ordinary service. The Baltimore & Ohio Railway has some heavy electric locomotives, but these are for hauling trains through a tunnel, to avoid the trouble and discomfort from the smoke and gases from the steam engines.

The early passenger cars were either open cars with cross seats, or had coach bodies on four-wheel platform cars. The coach-body cars on the Mohawk & Hudson Railway, in 1831, were 7 ft. 4 in. long and 5 ft. wide. In 1836 the American type of car was introduced on the Camden & Amboy Railway, having a long body mounted on two four-wheeled trucks. These cars seated 48 passengers, and cars for 60 passengers were in use in 1839, their cost being $2400. American day cars are now 60 to 80 ft. long, seating 60 to 84 passengers, and weighing from 30 to 47 tons. The standard day car of the Pennsylvania Railway is 60 ft. 7 in. long over all, and seats 66 passengers. Dining and sleeping cars weigh from 45 to 65 tons, much of the weight being due to the special equipment for the comfort and convenience of passengers, and consequently so much dead weight to be hauled. It can be said without dispute that in no other country have the railways done so much for the comfort and convenience of their passengers, and have charged so little therefor.

In Europe, the cars developed into the compartment system, with side doors, there being high transverse partitions with seats on each side, so that in a full compartment half the passengers must ride backward. The cars are usually short, with two or three axles, but about 1872 the American system of mounting cars on trucks was introduced, and longer cars on trucks are now somewhat extensively used. Within later years corridor cars have been introduced, with a corridor connecting the compartments. Such details as steam heat, toilet arrangements, ample light, luxurious finish, etc., which have long been a matter of course in this country, are quite “end of the century” improvements in Europe, and generally below the standards observed in this country.

Sleeping cars were used on the Cumberland Valley Railway (U. S. A.) in 1836. In 1856, Mr. T. L. Woodruff built a sleeping car, and in 1857 two were built by Mr. Webster Wagner and operated on the New York Central Railway. Mr. George M. Pullman began his experiments in 1859, and in 1864 he put in service on the Chicago & Alton Railway the first sleeping car with the berth arrangements now almost universally used. He pushed the business more vigorously than his predecessors and acquired many of their patents. The Pullman Palace Car Co. was organized in 1867, and in 1879 its various works were all concentrated in a new industrial town—called Pullman—near Chicago. In 1898 the company owned 2,428 cars, which were operated on 121,236 miles of railway, ran 190,562,758 miles, and carried 4,852,400 passengers. Most of the cars are in the United States, but some are in Europe and Australia. The Wagner Palace Car Co. owns 560 sleeping cars and 143 parlor cars. In Europe most of the long distance sleeping and dining car service is operated by the International Sleeping Car Co., which runs cars between Paris and Constantinople (72 hours), Paris and St. Petersburg (120 hours), Calais and Brindisi (25 hours).

Passenger cars are now usually lighted by oil, the mineral oil used in America being superior to the vegetable oils commonly used in Europe. Oil gas, compressed in tanks, is very extensively used, and gives an excellent light. The system was invented by Mr. Julius Pintsch, and was introduced in Germany in 1873, and in the United States in 1881. It is now applied to about 85,000 cars in 22 countries; 32,000 of these cars being in Germany, 17,000 in Great Britain, and 15,000 in the United States. The electric light is as yet used only on a few of the finest express trains, the current being generated either from a steam engine and dynamo in the baggage car, or from a dynamo on each car, driven from one of the car axles. Storage batteries maintain the light when the cars are at rest. American cars were heated by stoves at a very early date, and this developed into the hot water system, with a stove and circulating pipes in each car. Steam from the locomotive, however, is now generally employed, and its use is compulsory in some States. In Europe the passengers have to rely largely upon their own wraps and rugs.

In American freight cars, great improvements have been introduced, increasing the carrying capacity while reducing the weight. The capacity has been increased from 10 tons of load in 1870, to 30, 40, and even 50 tons in 1899 (an increase of 300 to 500 per cent). The weight has increased only from 10 to 15 or 17 tons (or 50 to 70 per cent). Cars are now being built entirely of steel, and while their first cost is greater, the cost per ton and the expenses of maintenance are less than for wooden cars of similar capacity. As sleeping, dining, parlor, tourist, and other special cars have been introduced for passenger traffic, so refrigerator, stock, horse, fruit, poultry, and furniture cars have been introduced for special requirements in freight traffic. In other countries, however, the use of such special equipment is much more limited. The ordinary foreign freight cars are the same as those of 30 or 40 years ago, being short four-wheel cars, weighing 5 tons, and carrying 8 to 10 tons. These are not well adapted to the handling of bulk freight, and greatly increased economy and facility in such traffic would result from the introduction of the American system, as has been done in Australia. In modern American practice, too, the cars are equipped with automatic couplers and power brakes, thus greatly increasing the safety and facility of operating heavy fast trains. In 1893, Congress passed a law requiring that by January 1, 1898, all freight cars should be equipped with automatic couplers and enough cars equipped with power brakes (operated from the engine) to put the trains entirely under the control of the enginemen. The date was afterwards extended to January 1, 1900.

As the speed and weight of trains increased, the dangers due to lack of brake power soon became alarmingly apparent, and numerous forms of continuous brakes were devised, to be applied to the wheels of every car, under the control of the engineman. In 1889, the British government passed the Railways Regulation Act, making compulsory the use of the block system, the interlocking system, and continuous brakes. In England and some other foreign countries, the vacuum brake (introduced about 1871) is largely used, but it is slower in action than the compressed air brake, and is therefore less efficient for long, heavy, and fast trains.

The Westinghouse brake is one of the most important factors in the safe and efficient handling of heavy and fast trains. Mr. George Westinghouse patented his straight-air brake in 1869, his plain automatic brake in 1872, and his quick-action freight train brake in 1887, while in 1892 he introduced his high-speed brake for express trains. Up to the opening of 1899, the Westinghouse brake had been applied to about 55,500 locomotives and 912,000 cars, of which 34,300 locomotives, 50,000 passenger cars and 750,000 freight cars were on American railways. With this brake, a passenger train of 300 tons, traveling at 60 miles per hour, can be stopped in about 4500 feet and about 90 seconds, or in 1200 feet and 31 seconds in case of emergency. A freight train of 800 tons, running at 30 miles per hour, can be stopped in about 950 feet in 32 seconds, or in 300 feet and 11 seconds by an “emergency” application. Very few countries have applied continuous brakes to freight cars, except the United States and Canada, and (to some extent) Russia and New South Wales.

The improvement in train service has been even greater than that in train equipment, and this improvement has been in speed, accommodation, and number of trains. Among the notable runs are those across the American and European continents. The Canadian Pacific Railway starts a train daily from each end of the line for a through run of 2900 miles. In 1888, a through train service (with sleeping and dining cars) was instituted between Paris and Constantinople, about 1800 miles, and through trains are run twice a week between Paris and St. Petersburg, 1600 miles. There is also a similar service between Calais and Brindisi, 1200 miles, in connection with the mail steamers between England and India. In 1898, the Trans-Siberian Railway was completed to Irkutsk, and a through train service between St. Petersburg and that city, 3230 miles, was commenced.

Railway trains were at first intended to have speeds of about 10 to 20 miles per hour, the latter being looked upon as almost excessive, but much higher speeds were very soon attained. There has been almost from the earliest days a public demand for higher and higher speeds, with consequent rivalry between the railways. The United States and Great Britain (and France within the past few years) have the fastest trains and by far the greater number of fast trains. The highest recorded train speed is that of the Exposition Flyer, 270 tons total, upon the New York Central Railway, May 10th, 1893. It ran a distance of one mile at the rate of 112 miles per hour, and again, on the same date, maintained a speed of 100 miles per hour, through a distance of five miles. As a daily train between New York and Chicago, it maintained a rate of 60 to 75 miles an hour, throughout the entire 980 miles of distance.

It will be seen that the speed of “100-miles-an-hour,” which is popularly looked upon as a sort of ideal, has been more than once exceeded, but it may be well to explain that such spectacular bursts of speed are really less important and less wonderful than the trips of 50 to 1000 miles at speeds averaging 50 to 65 miles per hour for the entire journey. Taking into account the loss of time by stops at stations, by changing engines, by the resistance of long grades, etc., it will be easily understood that in order to maintain the average speed from start to finish, the actual speeds must often range from 60 to 75 or even 80 miles per hour. The regular daily transcontinental train of the Canadian Pacific Railway has an average speed of 30 miles per hour, but maintains this for the trip of 2906 miles, which occupies 94½ hours. This is a train and a record of which railway men in general, and those of the Canadian Pacific Railway in particular, may well be proud. There are no such through trains in the United States, but in 1876 a special theatre train was run from New York to San Francisco in 3 days 7⅔ hours. In 1889, the time of the transcontinental mails was 5 days 8¼ hours, but that same year it was reduced to 4 days 12¾ hours, which schedule continued in force until 1899. On January 1, 1899, a new mail service was inaugurated, making the 3408 miles in 98½ hours, or at an average of 34½ miles per hour, including all stops, and the transfer of mail bags across Chicago by wagon from one station to another. The actual running speed is often 60 to 75 miles per hour for long stretches. Engines are changed 18 times and postal crews 7 times.

Fast passenger trains are a popular attraction, but only railway men can fully appreciate the advantages and economies of heavy trains for handling freight traffic. In Europe coal trains weigh from 300 to 400 tons, but in the United States the weight of coal, ore, and freight trains is from 800 to 2000 tons. Automatic couplers and power brakes enable the freight trains to be run as fast as passenger trains, with entire safety; improved cars carry greater loads, and more powerful locomotives are continually being put in service to haul heavier trains. The heaviest trains on record are as follows: (1) Pennsylvania Railway, 130 cars, 5213 tons, or 5560 tons with engine and tender; (2) New York Central Railway, 81 cars, 3478 tons, or 3595 tons with engine and tender. Both these were run in 1898, the length of journey being 160 and 140 miles.

The mails were carried by rail between Baltimore and Washington in 1834, on recommendation of the Postmaster-General. The U. S. railway service was instituted in August, 1864, between Chicago and Clinton, and the following figures indicate its wonderful development:—

-------------------------------+------------+-------------
| 1880 | 1898
-------------------------------+------------+-------------
Mileage run by mail cars | 65,763,993 | 187,483,187
Number of mail cars | —— | 3,649
Number of mail clerks | 2,946 | 7,999
Miles of railway operated over | 85,320 | 174,777
Tons of mail carried | 368,000 | 1,432,050

The railway express business was started in 1838 by Mr. W. F. Harnden, on a suggestion from Mr. Josiah Quincy, who had to travel weekly from Boston to New York, and was in the habit of taking small packages for business acquaintances. Mr. Alvin Adams became associated with Mr. Harnden, and in 1845 formed the Adams Express Co. In Great Britain, this business is conducted by the parcels-post and the railway companies, but in other European countries it is mainly in the hands of the post-office department.

A very remarkable feature of railway development is that from the beginning there has been a tendency to increased traffic, better service, and a steady reduction in rates. In the United States the average rates per mile since 1867 have been as follows:—

-----+------------+----------
| Passenger, | Freight,
Year | cents | cents
-----+------------+----------
1867 | 1.994 | 1.925
1870 | 2.392 | 1.889
1875 | 2.378 | 1.421
1880 | 2.442 | 1.232
1885 | 2.216 | 1.011
1890 | 2.167 | 0.941
1895 | 2.040 | 0.839
1896 | 2.019 | 0.806
-----+------------+----------

While the reduction in passenger rates has been comparatively small, it must be remembered that the safety, speed, comfort, and service have greatly improved. The marked reduction in freight rates has been made possible only by a still greater and more remarkable reduction in the cost of transportation. This has been effected by consolidation of companies, by improvements in roadway, bridges, etc., and by the introduction of heavier trains, with engines of greater power and cars of greater capacity. This economy can be still further extended. The reduction in rates has been much greater than that in the prices of commodities. Rates for wheat and hay, for instance, have decreased 23 and 20 per cent more than the market prices, and the rate for shipping anthracite coal to tidewater has decreased 50 per cent in the past ten years, while the price of the coal has decreased only 10 per cent. The average freight rate on the Pennsylvania Railway in 1898 was 0.536 cent per ton per mile, while the cost was 0.369 cent. The cheapness of transportation in the United States is shown by the following figures for 1898:—

Passengers carried one mile 13,000,000,000
Tons of freight carried one mile 95,000,000,000
Revenue from passenger service $26,000,000
Revenue from freight service $62,000,000
Distance railway carries 1 passenger to earn $1 profit 500 miles
Distance railway carries 1 ton to earn $1 profit 1530 miles
Average profit per passenger (including baggage) per mile 2-10 cent
Average profit per ton per mile 1-15 cent

The lowest passenger rates in the world are on the Indian railways. In Europe the passenger rates average higher than in the United States, though the accommodation is inferior.
