Chapter VIII: BIOGRAPHY.--Franz Liszt.--Large Portrait. 4981 (4)

According to Vitruvius, the works for manufacturing vermilion from Spanish ore in Rome were situated between the temple of Flora and Quirino. The ore was dried and treated in furnaces, to remove the native mercury it contained, and was then ground in iron mortars and washed. In addition, small quantities of quicksilver and vermilion were made at Almaden. The ancients describe other methods, among which Theophrastus speaks of using vinegar, which, however, appears from modern investigations to have been an erroneous account. Nothing definite is known concerning the methods of the Moors; we possess only as a proof that they produced mercury, an account of a quicksilver fountain in the marvelous palace of Abderrahman III., at Medina-Zahara, and the works of Rasis, an Arab. The Moors probably extracted mercury at Almaden, from the eighth to the twelfth century, by the use of furnaces called "xabecas," which latter, in the fourteenth century, were still employed by the Christians, who continued them till the seventeenth century, when German workmen replaced them by "reverberatory" furnaces, which in turn were superseded in 1646 by aludel or Bustamente furnaces. There is an anonymous description of the working with xabecas as practiced at Almaden in 1543, and later accounts in 1557 and 1565. The ore was put into egg-shaped vessels with a lid, the mineral being covered over with ashes. The vessels were packed in a furnace heated with wood, about 60 pounds being used per pound of quicksilver made. This system was also applied at the Guancavelica mines, discovered in Peru in 1566, where the xabecas were abandoned in 1633, being replaced by the furnaces invented by Lope Saavedra Barba, which there were called "busconiles," while in Spain they were named Bustamente furnaces, and elsewhere aludel furnaces. They were introduced at Almaden thirteen years after their first use in Peru by Juan Alfonso de Bustamente, Barba and his son having been lost at sea on their way to the Peninsula. In 1876, there were at Almaden, at the works at Buitrones, twenty such aludel furnaces and two Idria furnaces. D. Luis de la Escosura y Morrogh, from whose work we take the above notes, has followed the historical details of the growth of Almaden closely, and from his account of the method of working in 1878 we take some data:

It is not an easy matter to explain the classification of the ore at Almaden. _Metal_ is there called the richest mineral, composed of quartz impregnated with crystalline cinnabar. _Requiebro_ are middlings of medium richness, _China_ are smalls, and _Vaciscos_ the finest ore. Besides native mercury, which the ores of Almaden contain in greater or smaller quantity, the most abundant mineral is cinnabar, which is always crystalline and is often crystallized. The ores have, besides, a small quantity of selenium and iron pyrites intimately mixed with the cinnabar. The gangue is quartz, occasionally argillaceous and bituminous. The following are assays of some of the ores made by Escosura:

Metal. Requiebro. Vaciscos. China.
1 2 3 4 5 6 7 8
Cinnabar 29.1 21.2 13.3 10.2 5.1 2.8 1.2 0.86
Iron pyrites. 2.2 2.0 2.0 1.9 12.3 1.5 2.1 2.80
Bituminous matter 0.6 1.0 1.0 1.2 4.6 0.7 3.4 0.90
Gangue 67.5 74.8 82.1 76.5 77.5 93.3 90.2 93.50
---- ---- ---- ---- ---- ---- ---- -----
Total 99.4 94.0 98.8 98.9 99.5 98.3 98.7 98.06
Quicksilver 25.05 18.28 11.47 8.64 4.40 2.41 1.03 0.75

It appears to be a difficult matter to determine the average percentage of the various grades of ore. In 1872, a commission classified and sampled a lot of 300 tons with the following results:

Quantity, Per cent. Average of
Grade. No. kilos. mercury. grade.

Metal { 1. 81,890 23.86 }
{ 2. 14,970 22.65 } 24.80

Requiebro { 3. 12,240 15.20 }
{ 4. 17,000 10.50 } 12.47

China { 5. 31,890 3.84 }
{ 6. 32,360 1.17 } 1.75
{ 7. 28,960 0.10 }

Vaciscos 8. 78,320 9.24 9.24

This general average of 12.28 per cent. of mercury is pronounced higher than the usual run of the ore, which, it is stated, does not go above 7 to 8.50 per cent.

The furnace in which the ore is treated is cylindrical, 2 meters in diameter, and 3.70 meters high from a brick grate, supported by three arches to the arched roof. At the level of the grate is a charging orifice, and near the roof are openings into two chambers, from the bottom of which extend 12 lines of aludels, clay vessels, open at both ends, the middle being expanded. The mouth of one fits into the back end of the one following, a channel being thus formed through which the fumes to be condensed are passed. The lines of aludels which are laid on the ground terminate in a chamber, and for half the distance between the furnaces and these chambers the ground slopes downward, while for the other it slopes upward. Two furnaces are always placed side by side, and the pair have from 1,100 to 1,150 aludels.

The operation is as follows: A layer of poor quartz is spread over the brick grate; this is followed by a layer of smalls, and then by a layer of still finer stuff, all of it being low grade ore. On top of this are piled two-thirds of the _china_ of the charge on which the _metal_ is put. Then follows a layer of _requiebro_, another lot of _china_, and finally the _vaciscos_, shaped into balls, the whole charge amounting to about 11½ tons, which is put in from an hour and a half to two hours by three men. The charging orifice is then closed, the aludels are luted, and everything made tight. The fires under the brick grate are lighted and kept going for twelve hours, during which time furnaces, charge, and condensing apparatus are heated up. During this period, the temperature in the condensing-chamber at the end of the line of aludels runs up 40 or 50 degrees Celsius, and some mercury, evidently part of the native quicksilver, is noticed in it.

The temperature of the aludels in the immediate vicinity of the furnaces is about 140 degrees C. During this period, the consumption of fuel is four parts to every part of quicksilver produced. At its close, the fire is drawn, and the second period begins. The air entering through the brick arch is heated to from 200 to 300 degrees by contact with the layer of poor stuff, the cinnabar is ignited, and its sulphur oxidized, and the quicksilver vaporized and, condensing in the aludels, flows toward the depression in the central portion of the line. The temperature goes on increasing, until, twelve hours after the beginning of this period, the thermometer shows 212 degrees C. at the first aludels. This lasts for 18 hours, and then the third or "cooling period" begins, which takes from 24 to 26 hours, and during the beginning of which the temperature in the furnaces still rises. It is then opened and cooled down. A very elaborate series of observations made on the temperatures of various parts of the condensing apparatus of the Almaden furnaces has shown that at the aludels nearest to them the heat increases steadily until it reaches 249 degrees C., 44 hours after the beginning of the operation; that in the middle of the line, at the depression, the maximum is 50 degrees 50 hours after starting the fires; and that at the end it does not surpass 39 degrees. In the final condensing chamber, the temperature varied, running downward from 40 degrees during the heating period to 14 degrees, rising again to 29 degrees toward the close.

The loss of the quicksilver during the operation has been vary variously estimated, some stating that it is 50 per cent. and more, while others place it at 30 per cent. Escosura, in his work, gives the details of an operation checked by a royal commission in 1872, according to which the loss in working ore running 9.55 per cent. was only 4.41 per cent.--a loss which he considered inevitable. In 1806, two Idria furnaces were put up at Almaden, but the engineers are not favorably impressed with them. The first cost is stated to be more than ten times greater than that of an aludel furnace, while the capacity is only 50 per cent. greater. One pair of Idria furnaces in five years produced 120,000 kilogrammes of quicksilver, against 843,000 kilogrammes made by eight sets of the Bustamente furnaces, the cost per kilogramme of quicksilver being respectively 0.121 and 0.056 peseta.

THE BALLOON IN AERONAUTICS.

While it is undoubtedly true that the discovery of the balloon has very greatly retarded the science of aerostation, yet, in my opinion, its field of usefulness as a vehicle for pleasure excursions, for explorations, and for scientific investigations, has not been fully developed for the want of certain improvements, the nature of which it is the object of this paper to point out. The improvement of which I am about to speak relates to the regulation of the buoyancy of the balloon. This is now done by throwing out ballast or by allowing some of the gas to escape--a method which necessitates the carrying of an unwieldy amount of sand and the expenditure of an unnecessary amount of gas.

From the fire balloon invented by the Montgolfier Brothers, in 1782, to the superior hydrogen balloon of M.M. Charles and Robert, no material advancement has been made, except the employment of coal gas, first suggested by Mr. Green. The vast surface presented to the wind makes the balloon unmanageable in every breeze, and the aeronaut can do nothing but allow it to float along with the current. This is a difficulty which has been partly overcome, as was seen at the recent Paris Electrical Exhibition; but no one will ever be able to guide it in a direction opposite to a current of air. The aeronaut must ever content himself in being able to float in the direction of the current or at certain angles to its course; but to do this even is a matter which has not been successfully accomplished. An inflated balloon would ascend too high unless several hundred pounds of ballast were used to weight it down. This ballast serves another purpose, it is desirable to maintain the balloon at a uniform distance above the earth's surface, and as the two per cent. daily waste of gas diminishes the buoyancy of the balloon, it must be kept from descending by throwing off a certain amount of sand. Again, the heat of the sun and the action of warm air currents cause at times the volume of gas to undergo a sudden expansion, and then to prevent the balloon from running too high, the gas must be allowed to escape from the valve. The gas, under these circumstances, must also be allowed to escape in order to prevent the balloon from bursting. Presently the balloon will pass through a colder current of air and sudden condensation takes place, and the balloon would sink unless more ballast were thrown off. This process continues until the aeronaut has neither ballast nor gas left.

Now, I suggest that a large balloon be made with the mouth closed, so that no gas can escape; and that it carry enough ballast to keep it, under an ordinary temperature, at a certain distance from the ground. A pipe must enter the mouth of the balloon, one end of which opens in its interior and the other end in a gas reservoir which lies in the "basket" or "car." As soon as the gas undergoes an expansion, and a certain amount of pressure is made in this reservoir, a valve opens and a whistle signals the moment when the force pumps must be set to work to pump the air out of the balloon into the large _number two_ reservoir, the frame work of which forms the body of the car. Taking a certain amount of gas out of the balloon is equivalent to taking on more ballast, while by condensing this gas into a large reservoir, it is not allowed to escape, and when necessary can be sent back into the balloon and thus prevent the throwing off of ballast. Coal gas, under a certain pressure, becomes heavier than air (or at least equally heavy), and thus the gas pumped out of the balloon will of itself serve as ballast. This invention will enable the balloonist to keep himself at a uniform distance above the earth, will prevent the carrying of so much ballast and the expensive waste of gas, and will enable him to keep afloat at least ten times as long as by the old method. I have made a model and tested the above theory.

ARTISTS' HOMES. NO. 12--MR. WILLIAM EMERSON'S HOUSE AT LITTLE SUTTON, CHISWICK.

Little Sutton was an old house, parts of which were in existence before the time of Cromwell. It is situated in a picturesque old garden, surrounded by ivy-clad walls and fine trees, one of the cedars being extraordinarily large and perfect, its huge branches covering a space of over 90 ft. in diameter. The greater part of the old house, being uninhabitable through decay, was pulled down; the old parts are shown in black on the plan, and the new hatched. It is faced with red bricks, and red Corsehill stone dressings, and covered with tiles The plan was arranged so as to preserve the old kitchen, billiard-room, morning room, and conservatory. The hall, entered from a veranda in connection with the entrance-porch, is surrounded by a dado, the height of doors; the lower panels are filled with tiles made to design by the School of Art at Bombay. The woodwork is painted a mottled blue color, harmonizing with the general tone of the tiles, the whole being something the color of _lapis lazuli_. The staircase is divided from the hall by three arches, through which is seen the staircase-window, representing, in stained glass, the Earth, Air, and Water. Under the central arch is the fireplace, on the hood of which will eventually be a bronze figure of Orpheus, on a ground of mosaic. The floor is of marble mosaic, and round the border are the various beasts listening to the music, the trees and river, etc. Above the dado, and on the wooden panels of ceiling, will be the birds, etc. The woodwork of dining-room is plain American walnut, the panels of dado being filled with dark Japanese leather-paper. The panels and beams of ceiling are of stained and dull varnished fir. The drawing room woodwork, and furniture throughout, is painted a mottled greenish blue, after the same manner as the hall. The decorations of this room, when complete, are intended to illustrate Chaucer's "House of Fame." The chimney-piece, of alabaster, is surmounted by a Caen-stone design, on a rock of glass, showing the entrance to the castle, with the various figures mentioned in the poem, carved in half-round relief, and the gateway itself also richly and quaintly carved; the rock of glass representing the ice on which the castle was supposed to be built, and on it are cut the various famous names of the world's history. In the frieze all round the room will be the figure of Fame and the various groups of suppliants, and the pillars with the groups upholding the renown of ancient cities and nations, etc., executed in very low relief, and painted on a ground of blue and gold. The panels of ceilings will have conventional designs and the heavenly bodies on ground of gold and blue. The morning and other rooms have no particular scheme of decoration prepared, and are simply painted and papered in quiet tones.

We publish a longitudinal section, taken through the hall and drawing-room, with part of the dining-room on the left and part of the library on the right-hand side. The beautifully-modeled plaster frieze, with the central figure of Fame, is shown in the drawing-room, and illustrates Chaucer's "House of Fame," the whole being elaborately colored in harmony with the purposes and general tone of the room, which is in blue and gold. The hooded mantelpiece in the library is entirely in concrete, to be richly painted and gilded. The drawing, with the assistance of the description, will explain itself.--_Building News._

MEMORABLE ENGLISH HOUSES.

In the year 1864, a letter appeared in the _Journal of the Society of Arts_ from a correspondent, who suggested that the Society of Arts should offer a prize or prizes for designs of memorial tablets to be affixed to houses associated with distinguished persons, and in the same year a series of suggested inscriptions was reprinted from the _Builder_. The subject having been brought under the notice of the council, a committee was appointed in 1866 to consider and report how the society might promote the erection of statues or other memorials of persons eminent in arts, manufactures, and commerce, and, at the first meeting of the committee, on May 7, Mr. George C.T. Bartley submitted some memoranda on the proposal to place labels on houses in the metropolis known to have been inhabited by celebrated persons In 1837, the first tablet was erected by the society in Holles Street, Cavendish Square, on the house where Byron was born. Other tablets were soon afterward put up, and the erection of these memorials has been continued to the present time.

The house in Leicester Square, upon which a tablet in memory of Hogarth has been erected, is occupied by Archbishop Tenison's school, for which the house was rebuilt. The original building, in which Hogarth lived for several years, was long known as the "Sablonière Hotel." John Hunter lived next door after Hogarth's death. Of the four worthies who were intimately connected with Leicester Square, viz, Hunter, Hogarth, Newton and Reynolds, and whose busts are now set up at the four corners of the inclosure, the last three have tablets erected.

The house in St. Martin's Street, which is now occupied by the schools attached to the Orange Street Chapel, is in much the same condition as when Sir Isaac Newton lived in it, from 1710 to 1727, except that the old red bricks have been covered with stucco, and an observatory on the roof has been taken away within the last few years.

Flaxman had several London residences, but the house in Buckingham Street, Fitzroy Square, is the one with which he is most intimately associated, as he lived in it during the prime of his artistic career. He went there in 1796, when he returned from Rome, and there he died in 1826, being buried in the ground adjoining old St. Pancras Church and belonging to the parish of St. Giles-in-the fields. The house is on the south side of the street, close by Great Titchfield Street.

Canning's house, on the south side of Conduit Street is greatly changed since the great statesman lived in it. It originally formed a wing of Trinity Chapel, which has been swept away within the last few years. This chapel was the successor of the chapel-on-wheels which was used at the Hounslow camp in the reign of James II., and was subsequently brought up to London. It is shown in Kip's view of old Burlington House as standing in the fields at the back of that house. When Conduit Street was built, a chapel was erected on the south side to supersede the chapel-on-wheels. The house on the west side of the chapel, where Canning lived for a time, was subsequently inhabited for many years by the famous physician, Dr. Elliotson, F.R.S. After his death, the front was altered, and a large shop window made, as seen in the accompanying figure. It is now in the possession of Mr. Streeter, the jeweler.

Dr. Johnson had so many residences in London that there is some difficulty in choosing the one that is most interesting to us. The house in Gough Square has special claims to attention, as it was there that the great lexicographer chiefly compiled his dictionary. The garret, with its slanting roof, in which his amanuenses worked, and his own study are still to be been. Johnson himself, in his "Life of Milton," observes, "I cannot but remark a kind of respect, perhaps unconsciously, paid to this great man by his biographers; every house in which he resided is historically mentioned, as if it were an injury to neglect naming any place that he honored by his presence." Emboldened by this expression of opinion, Boswell one evening, in the year 1779, ventured to ask Johnson the names of some of his residences, and he obtained the following list, which he printed in his "Life of Johnson:" (1) Exeter Street, off Catherine Street, Strand, (2) Greenwich; (3) Woodstock Street, near Hanover Square; (4) Castle Street, Cavendish Square, No. 6, (5) Strand; (6) Boswell Court; (7) Strand again; (8) Bow Street; (9) Holborn; (10) Fetter Lane; (11) Holborn again, (12) Gough Square; (18) Staple's Inn; (14) Gray's Inn; (15) Inner Temple Lane, No. 1; (16) Johnson's Court, No. 7; (17) Bolt Court, No. 8. In this last place he died in 1784.

In April, 1879, the corporation of the city of London were asked to co-operate in this work, and to undertake the erection of suitable memorial tablets within the city boundaries. The matter was referred to the city lands committee, with which body the secretary has had several communications with respect to the localities suggested for memorials, the result being that the committee agreed to erect such tablets within the city boundaries.--_Journal of the Society of Arts._

DOMESTIC SUGAR PRODUCTION.

The value of sugar imported into the United States, is greater than that of any other single article of commerce. In the year 1880 it appears that over one thousand eight hundred and twenty-nine million pounds of sugar were brought here from other countries, at a cost of nearly one hundred and twenty million dollars, including customs duty. Moreover, the consumption of sugar, _per capita_, in this country is rapidly increasing. It was, during the ten years next preceding 1870, only 28 pounds on the average per annum, but, in the ten years next following, an average of 38 pounds per annum were consumed for each person of the population of this country. This appears to be an increase of 35 per centum in ten years.

The subject of domestic cultivation of sugar bearing plants is, therefore, one of great importance to this nation, and it has accordingly engaged the attention of the U.S. Commissioner of Agriculture, and many experiments have been made in different parts of the country in the propagation of the various canes, roots, etc., from which sugar can be made. Among sugar-bearing plants, beside the regular sugar cane, are, sorghum, sugar beet, maple, watermelon, sweet and white potato, and corn stalk.

Statistics show that of the 12,000,000,000 pounds of sugar produced in the world, about three-fourths comes from the sugar cane, and the other fourth comes mainly from the sugar beet. Of the total quantity, only about one seventieth is produced in the United States, and that is mainly cane sugar from Louisiana. The beet sugar has formerly been mainly produced in Europe. First France, second Germany, third Russia, then Belgium, Austria, Holland, Sweden, and Italy.

The consumption of sugar in Great Britain is much greater _per capita_ than in the United States, about 65 pounds, or nearly double; while in Germany 19 pounds per annum are used on an average by each person, and in Russia the consumption is much less.

The importance of this subject to the United States, where the consumption of sugar is increasing out of ratio to the production of sugar-bearing plants, and where agricultural independence should be realized, as we have already attained and maintained political independence, and almost independence in manufacturing industries, has called out Mr. Lewis S. Ware, a member of the American Chemical Society, etc., in a pamphlet of over 60 pages, entitled a "_Study of the Various Sources of Sugar_."

From this publication it appears that the main source of sugar supply must still be _sucrose_, cane sugar, even in spite of the best efforts of the general government and of the State agricultural organizations to introduce sugar-bearing plants that will thrive in the temperate and colder latitudes of this country. With the single exception of the sugar beet, he seems to disparage all attempts to produce practical sugar from hardy plants, or those that will mature in the region of frosts in winter. Even sorghum, that has for twenty years held a place in the hopes of the northern farmer, has declined so that the alleged production of half a million pounds in 1866 had became barely a twelfth of a million pounds in 1877.

In his remarks on the synopsis of one hundred and eleven experiments, made at Washington, he says: "As may be noticed, thirty-five of them (111) would yield zero. If we take the average of the hundred and eleven experiments, we find as a yield 4.5 per cent., which result cannot possibly be practically accepted. In other words, our government, notwithstanding the favorable conditions under which they were made, prove that the sorghum utilization is fallacy in every sense of the word." ... "If sorghum is to be grown for its sirup, or for fodder, it will evidently render excellent service." It seems that less than four per cent. of crystallizable sugar in the sorghum juice will not pay the cost of making sugar from it, as it will not crystallize in a reasonable time, on account of the glucose in the juice, which, with the other impurities, will prevent the ready crystallization of four or five times their own weight of sucrose.

From the early history of sorghum, it appears that it was known as _sorgo_ in the sixteenth century, while twenty or thirty varieties were known under different names in Egypt, Arabia, and Africa. Some of the names are, Chinese sugar cane, (sorgo), India cane, emphee or Coffers' bread, paindes anges, etc.

The later history of it shows that in 1850, Count Montigny sent the first samples from China to Europe. It had been used in the former country for thousands of years for the manufacture of red dye. The seeds were afterward sold in France for a _franc_ each.

A variety came later to this country from Africa, through the agency of an Englishman named Wray, to whom is charged the effects of the delusive experiments of trying to make crystallized sugar from its juice, which have been going on in this country for twenty years. But two varieties of sorghum now remain, known as the Chinese and African types. Of all the other sugar plants, none except the maple tree (besides the sugar cane and the beet) seem to have yielded sugar to pay the cost of manufacture. The maple tree has yielded a total of 41,000,000 pounds in 1877. But as an industry by itself, it appears to be unprofitable, and maple sugar must be, and generally is, sold at a higher price per pound than cane sugar; moreover, it has not the qualities that are required in a general sweetner for culinary purposes.

The variety of sugar plant called amber cane is not very clearly defined, but it may be taken, from the description of the juice as to crystallizing qualities, as no better sugar producer than sorghum. It, with sorghum, is classed as a sub-variety of sugar cane, which will yield sirup and fodder, but will not crystallize under several months' time, and even then in but small percentage.

On the whole it appears, as before stated, that the sugar beet is the only practicable source of sugar for the Northern States, which, as experimentally shown, can be raised at a profit of forty six dollars per acre, against twenty dollars per acre, the profit of sugar making from cane in Louisiana. Upon this showing several beet sugar factories have been started in the United States and in Canada, and their products are said to be satisfactory, and have been sold at a profit in competition with imported beet sugar.

Mr. Ware recommends the establishment of beet sugar factories on a larger scale, to be managed by men who have had experience in this particular kind of sugar making, which seems to be a practical means of supplying ourselves with home-made sugar. It must be remembered, however, that the successful cultivation of an ample supply of beets to keep them at work is an essential prerequisite.

HERALD ISLAND.

John Muir, the geologist with the Corwin Arctic Expedition, describes, as follows, the characteristics of Herald Island, hitherto known only as an inaccessible rock seen by a few venturesome whalers and explorers:

After so many futile efforts had been made to reach this little ice bound island, everybody seemed wildly eager to run ashore and climb to the summit of its sheer granite cliffs. At first a party of eight jumped from the bowsprit chains and ran across the narrow belt of margin ice and madly began to climb up an excessively steep gully, which came to an end in an inaccessible slope a few hundred feet above the water. Those ahead loosened and sent down a train of granite bowlders, which shot over the heads of those below in a far more dangerous manner than any of the party seemed to appreciate. Fortunately nobody was hurt, and all made out to get down in safety. While this remarkable piece of mountaineering and Arctic exploration was in progress, a light skin-covered boat was dragged over the ice and launched on a strip of water that stretched in front of an accessible ravine, the bed of an ancient glacier, which I felt assured would conduce by an easy grade to the summit of the island. The slope of this ravine for the first hundred feet or so was very steep, but inasmuch as it was full of firm, icy snow, it was easily ascended by cutting steps in the face of it with an ax that I had brought from the ship for the purpose. Beyond this there was not the slightest difficulty in our way, the glacier having graded a fine, broad road.

ON THE SUMMIT.

Kellet, who discovered this island in 1849, and landed on it under unfavorable circumstances, describes it as an inaccessible rock. The sides are, indeed, in general, extremely sheer and precipitous all around, though skilled mountaineers would find many gullies and slopes by which they might reach the summit. I first pushed on to the head of the glacier valley, and thence along the back bone of the island to the highest point, which I found to be about twelve hundred feet above the level of the sea. This point is about a mile and a half from the northwest end, and four and a half from the northeast end, thus making the island about six miles in length. It has been cut nearly in two by the glacial action it has undergone, the width at this lowest portion being about half a mile, and the average width about two miles. The entire island is a mass of granite with the exception of a patch of metamorphic slate near the center, and no doubt owes its existence with so considerable a height to the superior resistance this granite offered to the degrading action of the northern ice sheet, traces of which are here plainly shown, as well as on the shores of Siberia and Alaska, and down through Behring Strait, southward, beyond Vancouver Island. Traces of the subsequent partial glaciation it has been subjected to are also manifested in glacial valleys of considerable depth as compared with the size of the island. I noticed four of these, besides many marginal glacial grooves around the sides. One small remnant with feeble action still exists near the middle of the island. I also noted several scored and polished patches on the hardest and most enduring of the outswelling rock bosses. This little island, standing as it does alone out in the Polar Sea, is a fine glacial monument.

A MIDNIGHT OBSERVATION.

The midnight hour I spent alone on the highest summit, one of the most impressive hours of my life. The deepest silence seemed to press down on all the vast, immeasurable, virgin landscape. The sun near the horizon reddened the edges of belted cloud bars near the base of the sky, and the jagged ice bowlders crowded together over the frozen ocean stretching indefinitely northward, while more than a hundred miles of that mysterious Wrangell Land was seen blue in the northwest--a wavering line of hill and dale over the white and blue ice prairie and pale gray mountains beyond, well calculated to fix the eye of a mountaineer; but it was to the far north that I ever found myself turning, where the ice met the sky. I would fain have watched here all the strange night, but was compelled to remember the charge given me by the captain, to make haste and return to the ship as soon as I should find it possible, as there was ten miles of shifting, drifting ice between us and the open sea.

PLANT LIFE ON HERALD ISLAND.

I therefore began the return journey about one o'clock this morning, after taking the compass bearings of the principal points within sight on Wrangell Land, and making a hasty collection of the flowering plants on my way. I found one species of poppy, quite showy, and making considerable masses of color on the sloping uplands, three or four species of saxifrage, one silene, a draba, dwarf willow, stellaria, two golden compositæ, two sedges, one grass, and a veronica, together with a considerable number of mosses and lichens, some of them quite showy and so abundant as to form the bulk of the color over the gray granite.

INHABITANTS OF THE CLIFFS.

Innumerable gulls and murres breed on the steep cliffs, the latter most abundant. They kept up a constant din of domestic notes. Some of them are sitting on their eggs, others have young, and it seems astonishing that either eggs or the young can find a resting place on cliffs so severely precipitous. The nurseries formed a lively picture--the parents coming and going with food or to seek it, thousands in rows standing on narrow ledges like bottles on a grocer's shelves, the feeding of the little ones, the multitude of wings, etc.

M. Bouchut's experiments with pepsine for destroying worms in the stomach and bowels have been continued with extremely promising results. Even the tapeworm succumbs to the digestive action of pepsine in large doses, while the more highly organized tissues of the stomach are unaffected.

FRANZ LISZT.

On the 22d day of October, 1811, Franz Liszt, the greatest pianist of the last half century, was born at Raiding, in Hungary, and the entire musical world was united in celebrating his seventieth birthday, which took place this year.

What can be more appropriate than to take a look at the past and recall some of the important events of Liszt's so very interesting life? To recall his first appearance as a "wonder" child in his native town, the blessing and kiss he received a few years later from the immortal Beethoven, his great triumphs in the Paris salons and the defeat of his rival Thalberg. After the appearance of the violin virtuoso Paganini, he resolved to attain the highest development of his musical genius and to become so world-renowned as none has been before him, and in this was successful. He has not only maintained his standing as the greatest master of modern piano virtuosos, but has had the greatest influence on his followers and scholars, Taussig, v. Bulow, Mr. and Mme. Bronsart, Menter, and other younger and older pianists who have had the benefits of his instruction for a greater or less length of time, so that it can be justly claimed that the majority of our present virtuosos owe their success and fame directly or indirectly to the abilities of Liszt.

Liszt is endowed with that great gift of treating every individual in the manner most favorable to the development of its traces of artistic ability and desires, and this accounts for his wonderful results as instructor and master.

But no picture of Liszt would be perfect without a _résumé_ or recapitulation of his compositions.

After a most perfect transposition and preparation of numerous works of Beethoven, Schubert, and Berlioz, and after making their compositions popular and introducing numerous valuable novelties in the art of playing piano, he produced his "Symphonische Dichtungen" (Symphonic Poems).

These highly dramatic compositions, in which he follows Berlioz and often produces the most astonishing effects of sounds, however, did not find entire approbation with the public, and did not succeed in popularizing themselves. But that fact can be recorded in his favor that every programme containing Liszt's "Dante," or Faust Symphony, or "Mazeppa," receives more than ordinary attention from the public. The same is the case with his solo songs with piano accompaniment, in which, however, ingenious details often tend to drown the original melody. Of his quartets, some have become highly popular with singing societies and form part of their _repertoire_. The crowning point of Liszt's compositions is to be found in sacred music, for instance in his mass known as the "Grauer Messe," composed for the dedication of the Cathedral at Grau, in Hungary; the Crowning mass, and his two oratorios, "Die heilige Elisabeth" and "Christus." But even they caused a decided difference of opinion; and if some knew no bounds for their enthusiasm, others could not find an end for their condemnation. Such works should not be treated too lightly, and a thorough and impartial examination will show that a place of honor must be accorded to them in the history of music. Since the "Heilige Elisabeth" has been produced in several cities of Germany it has been viewed more favorably and disarmed many of the opponents.

But Liszt also belongs to the literary fraternity, and his works, published by Breitkopf & Hartel, contain some of the best ever written in regard to art and artists. They were mostly written in elegant French originally, and relate to the social position of artists and the state of the art of music in certain cities or even an entire country. A part of his works is devoted to the music of gypsies, and to a true and honest history of the life of his friend Chopin.

Then again we find him preparing the path to the hearts of the public for Berlioz, Schumann, Wagner, Robert Franz, and Meyerbeer. Liszt has certainly collected enormous sums of money in his successful career, but as fast as he reaps his earnings he gives them to those needing assistance, and it is almost entirely to him that the inhabitants of Bonn, on the Rhine, owe their beautiful Beethoven Monument, and during the last years Liszt has been untiring in giving concerts and collecting money for a monument for the greatest of the great, Johann Sebastian Bach.

Liszt is an artist in every sense of the word, and we should all wish that he will remain among us for many years more.
