Chapter IX: Part 9

As in the case of the trumpet, the use of the kettledrum was placed under great restrictions in Germany and France and to some extent in England, but it was used in churches with the trumpet.[16] No French or German regiment was allowed kettledrums unless they had been captured from the enemy, and the _timbalier_ or the _Heerpauker_ on parade, in reviews and marches generally, rode at the head of the squadron; in battle his position was in the wings. In England, before the Restoration, only the Guards were allowed kettledrums, but after the accession of James II. every regiment of horse was provided with them.[17] Before the Royal Regiment of Artillery was established, the master-general of ordnance was responsible for the raising of trains of artillery. Among his retinue in time of war were a trumpeter and kettledrummer. The kettledrums were mounted on a chariot drawn by six white horses. They appeared in the field for the first time in a train of artillery during the Irish rebellion of 1689, and the charges for ordnance include the item, "large kettledrums mounted on a carriage with cloaths marked I.R. and cost £158, 9s."[18] A model of the kettledrums with their carriage which accompanied the duke of Marlborough to Holland in 1702 is preserved in the Rotunda Museum at Woolwich. The kettledrums accompanied the Royal Artillery train in the Vigo expedition and during the campaign in Flanders in 1748. Macbean[19] states that they were mounted on a triumphal car ornamented and gilt, bearing the ordnance flag and drawn by six white horses. The position of the car on march was in front of the flag gun, and in camp in front of the quarters of the duke of Cumberland with the artillery guns packed round them. The kettledrummer had by order "to mount the kettledrum carriage every night half an hour before the sun sett and beat till gun fireing." In 1759 the kettledrums ceased to form part of the establishment of the Royal Artillery, and they were deposited, together with their carriage, in the Tower, at the same time as a pair captured at Malplaquet in 1709. These Tower drums were frequently borrowed by Handel for performances of his oratorios.

The kettledrums still form part of the bands of the Life Guards and other cavalry regiments. (K. S.)

FOOTNOTES:

[2] This rhythmical use of kettledrums was characteristic of the
military instrument of percussion, rather than the musical member of
the orchestra. During the middle ages and until the end of the 18th
century, the two different notes obtainable from the pair of
kettledrums were probably used more as a means of marking and varying
the rhythm than as musical notes entering into the composition of the
harmonies. The kettledrums, in fact, approximated to the side drums
in technique. The contrast between the purely rhythmical use of
kettledrums, given above, and the more modern musical use is well
exemplified by the well-known solo for four kettledrums in
Meyerbeer's _Robert le Diable_, beginning thus--

KEUPER, in geology the third or uppermost subdivision of the Triassic system. The name is a local miners' term of German origin; it corresponds to the French _marnes irisées_. The formation is well exposed in Swabia, Franconia, Alsace and Lorraine and Luxemburg; it extends from Basel on the east side of the Rhine into Hanover, and northwards it spreads into Sweden and through England into Scotland and north-east Ireland; it appears flanking the central plateau of France and in the Pyrenees and Sardinia. In the German region it is usual to divide the Keuper into three groups, the _Rhaetic_ or upper Keuper, the middle, _Hauptkeuper_ or _gypskeuper_, and the lower, _Kohlenkeuper_ or _Lettenkohle_. In Germany the lower division consists mainly of grey clays and _schieferletten_ with white, grey and brightly coloured sandstone and dolomitic limestone. The upper part of this division is often a grey dolomite known as the Grenz dolomite; the impure coal beds--_Lettenkohle_--are aggregated towards the base. The middle division is thicker than either of the others (at Göttingen, 450 metres); it consists of a marly series below, grey, red and green marls with gypsum and dolomite--this is the _gypskeuper_ in its restricted sense. The higher part of the series is sandy, hence called the _Steinmergel_; it is comparatively free from gypsum. To this division belong the Myophoria beds (_M. Raibliana_) with galena in places; the Estheria beds (_E. laxitesta_); the Schelfsandstein, used as a building-stone; the Lehrberg and Berg-gyps beds; Semionotus beds (_S. Bergeri_) with building-stone of Coburg; and the Burgand Stubensandstein. The salt, which is associated with gypsum, is exploited in south Germany at Dreuze, Pettoncourt, Vie in Lorraine and Wimpfen on the Neckar. A ½-metre coal is found on this horizon in the Erzgebirge, and another, 2 metres thick, has been mined in Upper Silesia. The upper Keuper, Rhaetic or _Avicula contorta_ zone in Germany is mainly sandy with dark grey shales and marls; it is seldom more than 25 metres thick. The sandstones are used for building purposes at Bayreuth, Culmbach and Bamberg. In Swabia and the Wesergebirge are several "bone-beds," thicker than those in the middle Keuper, which contain a rich assemblage of fossil remains of fish, reptiles and the mammalian teeth of _Microlestes antiquus_ and _Triglyptus Fraasi_. The name Rhaetic is derived from the Rhaetic Alps where the beds are well developed; they occur also in central France, the Pyrenees and England. In S. Tirol and the Judicarian Mountains the Rhaetic is represented by the Kössener beds. In the Alpine region the presence of coral beds gives rise to the so-called "Lithodendron Kalk."

In Great Britain the Keuper contains the following sub-divisions: _Rhaetic or Penarth beds_, grey, red and green marls, black shales and so-called "white lias" (10-150 ft.). _Upper Keuper marl_, red and grey marls and shales with gypsum and rock salt (800-3000 ft.). _Lower Keuper sandstone_, marls and thin sandstones at the top, red and white sandstones (including the so-called "waterstones") below, with breccias and conglomerates at the base (150-250 ft.). The basal or "dolomitic conglomerate" is a shore or scree breccia derived from local materials; it is well developed in the Mendip district. The rock-salt beds vary from 1 in. to 100 ft. in thickness; they are extensively worked (mined and pumped) in Cheshire, Middlesbrough and Antrim. The Keuper covers a large area in the midlands and around the flanks of the Pennine range; it reaches southward to the Devonshire coast, eastward into Yorkshire and north-westward into north Ireland and south Scotland. As in Germany, there are one or more "bone beds" in the English Rhaetic with a similar assemblage of fossils. In the "white lias" the upper hard limestone is known as the "sun bed" or "Jew stone"; at the base is the Cotham or landscape marble.

Representatives of the Rhaetic are found in south Sweden, where the lower portion contains workable coals, in the Himalayas, Japan, Tibet, Burma, eastern Siberia and in Spitzbergen. The upper portion of the Karroo beds of South Africa and part of the Otapiri series of New Zealand are probably of Rhaetic age.

The Keuper is not rich in fossils; the principal plants are
cypress-like conifers (_Walchia_, _Voltzia_) and a few calamites with
such forms as _Equisetum arenaceum_ and _Pterophyllum Jaegeri_,
_Avicula contorta_, _Protocardium rhaeticum_, _Terebratula gregaria_,
_Myophoria costata_, _M. Goldfassi_ and _Lingula tenuessima_,
_Anoplophoria lettica_ may be mentioned among the invertebrates.
Fishes include _Ceratodus_, _Hybodus_ and _Lepidotus_. Labyrinthodonts
represented by the footprints of Cheirotherium and the bones of
_Labyrinthodon_, _Mastodonsaurus_ and _Capitosaurus_. Among the
reptiles are _Hyperodapedon_, _Palaeosaurus_, _Zanclodon_,
_Nothosaurus_ and _Belodon_. _Microlestes_, the earliest known
mammalian genus, has already been mentioned.

KEW, a township in the Kingston parliamentary division of Surrey, England, situated on the south bank of the Thames, 6 m. W.S.W. of Hyde Park Corner, London. Pop. (1901), 2699. A stone bridge of seven arches, erected in 1789, connecting Kew with Brentford on the other side of the river, was replaced by a bridge of three arches opened by Edward VII. in 1903 and named after him. Kew has increased greatly as a residential suburb of London; the old village consisted chiefly of a row of houses with gardens attached, situated on the north side of a green, to the south of which is the church and churchyard and at the west the principal entrance to Kew Gardens. From remains found in the bed of the river near Kew bridge it has been conjectured that the village marks the site of an old British settlement. The name first occurs in a document of the reign of Henry VII., where it is spelt Kayhough. The church of St Anne (1714) has a mausoleum containing the tomb of the duke of Cambridge (d. 1850) son of George III., and is also the burial-place of Thomas Gainsborough the artist, Jeremiah Meyer the painter of miniatures (d. 1789), John Zoffany the artist (d. 1810), Joshua Kirby the architect (d. 1774), and William Aiton the botanist and director of Kew Gardens (d. 1793).

The free school originally endowed by Lady Capel in 1721 received special benefactions from George IV., and the title of "the king's free school."

The estate of Kew House about the end of the 17th century came into the possession of Lord Capel of Tewkesbury, and in 1721 of Samuel Molyneux, secretary to the prince of Wales, afterwards George II. After his death it was leased by Frederick prince of Wales, son of George II., and was purchased about 1789 by George III., who devoted his leisure to its improvement. The old house was pulled down in 1802, and a new mansion was begun from the designs of James Wyatt, but the king's death prevented its completion, and in 1827 the portion built was removed. Dutch House, close to Kew House, was sold by Robert Dudley, earl of Leicester, to Sir Hugh Portman, a Dutch merchant, late in the 16th century, and in 1781 was purchased by George III. as a nursery for the royal children. It is a plain brick structure, now known as Kew Palace.

The Royal Botanic Gardens of Kew originated in the exotic garden formed by Lord Capel and greatly extended by the princess dowager, widow of Frederick, prince of Wales, and by George III., aided by the skill of William Aiton and of Sir Joseph Banks. In 1840 the gardens were adopted as a national establishment, and transferred to the department of woods and forests. The gardens proper, which originally contained only about 11 acres, were subsequently increased to 75 acres, and the pleasure grounds or arboretum adjoining extend to 270 acres. There are extensive conservatories, botanical museums, including the magnificent herbarium and a library. A lofty Chinese pagoda was erected in 1761. A flagstaff 159 ft. high is made out of the fine single trunk of a Douglas pine. In the neighbouring Richmond Old Park is the important Kew Observatory.

KEWANEE, a city of Henry county, Illinois, U.S.A., in the N. W. part of the state, about 55 m. N. by W. of Peoria. Pop. (1900), 8382, of whom 2006 were foreign-born; (1910 census), 9307. It is served by the Chicago Burlington & Quincy railroad and by the Galesburg & Kewanee Electric railway. Among its manufactures are foundry and machine-shop products, boilers, carriages and wagons, agricultural implements, pipe and fittings, working-men's gloves, &c. In 1905 the total factory product was valued at $6,729,381, or 61.5% more than in 1900. Kewanee was settled in 1836 by people from Wethersfield, Connecticut, and was first chartered as a city in 1897.

KEY, SIR ASTLEY COOPER (1821-1888), English admiral, was born in London in 1821, and entered the navy in 1833. His father was Charles Aston Key (1793-1849), a well-known surgeon, the pupil of Sir Astley Cooper, and his mother was the latter's niece. After distinguishing himself in active service abroad, on the South American station (1844-1846), in the Baltic during the Crimean War (C.B. 1855) and China (1857), Key was appointed in 1858 a member of the royal commission on national defence, in 1860 captain of the steam reserve at Devonport, and in 1863 captain of H.M.S. "Excellent" and superintendent of the Royal Naval College. He had a considerable share in advising as to the reorganization of administration, and in 1866, having become rear-admiral, was made director of naval ordnance. Between 1869 and 1872 he held the offices of superintendent of Portsmouth dockyard, superintendent of Malta dockyard, and second in command in the Mediterranean. In 1872 he was made president of the projected Royal Naval College at Greenwich, which was organized by him, and after its opening in 1873 he was made a K.C.B, and a vice-admiral. In 1876 he was appointed commander-in-chief on the North American and West Indian station. Having become full admiral in 1878, he was appointed in 1879 principal A.D.C., and soon afterwards first naval lord of the admiralty, retaining this post till 1885. In 1882 he was made G.C.B. He died at Maidenhead on the 3rd of March, 1888.

KEY, THOMAS HEWITT (1799-1875), English classical scholar, was born in London on the 20th of March, 1799. He was educated at St John's and Trinity Colleges, Cambridge, and graduated 19th wrangler in 1821. From 1825 to 1827 he was professor of mathematics in the university of Virginia, and after his return to England was appointed (1828) professor of Latin in the newly founded university of London. In 1832 he became joint headmaster of the school founded in connexion with that institution; in 1842 he resigned the professorship of Latin, and took up that of comparative grammar together with the undivided headmastership of the school. These two posts he held till his death on the 29th of November 1875. Key is best known for his introduction of the crude-form (the uninflected form or stem of words) system, in general use among Sanskrit grammarians, into the teaching of the classical languages. This system was embodied in his _Latin Grammar_ (1846). In _Language, its Origin and Development_ (1874), he upholds the onomatopoeic theory. Key was prejudiced against the German "Sanskritists," and the etymological portion of his _Latin Dictionary_, published in 1888, was severely criticized on this account. He was a member of the Royal Society and president of the Philological Society, to the _Transactions_ of which he contributed largely.

See _Proceedings of the Royal Society_, vol. xxiv. (1876); R. Ellis in
the _Academy_ (Dec. 4, 1875); J. P. Hicks, _T. Hewitt Key_ (1893),
where a full list of his works and contributions is given.

KEY (in O. Eng. _caég_; the ultimate origin of the word is unknown; it appears only in Old Frisian _kei_ of other Teutonic languages; until the end of the 17th century the pronunciation was _kay_, as in other words in O. Eng. ending in _aég_; cf. _daég_, day; _claég_, clay; the _New English Dictionary_ takes the change to kee to be due to northern influence), an instrument of metal used for the opening and closing of a lock (see LOCK). Until the 14th century bronze and not iron was most commonly used. The terminals of the stem of the keys were frequently decorated, the "bow" or loop taking the form sometimes of a trefoil, with figures inscribed within it; this decoration increased in the 16th century, the terminals being made in the shape of animals and other figures. Still more elaborate ceremonial keys were used by court officials; a series of chamberlains' keys used during the 18th and 19th centuries in several courts in Europe is in the British Museum. The terminals are decorated with crowns, royal monograms and ciphers. The word "key" is by analogy applied to things regarded as means for the opening or closing of anything, for the making clear that which is hidden. Thus it is used of an interpretation as to the arrangement of the letters or words of a cipher, of a solution of mathematical or other problems, or of a translation of exercises or books, &c., from a foreign language. The term is also used figuratively of a place of commanding strategic position. Thus Gibraltar, the "Key of the Mediterranean," was granted in 1462 by Henry IV. of Castile, the arms, _gules_, a castle proper, with key pendant to the gate, _or_; these arms form the badge of the 50th regiment of foot (now 2nd Batt. Essex Regiment) in the British army, in memory of the part which it took in the siege of 1782. The word is also frequently applied to many mechanical contrivances for unfastening or loosening a valve, nut, bolt, &c., such as a spanner or wrench, and to the instruments used in tuning a pianoforte or harp or in winding clocks or watches. A farther extension of the word is to appliances or devices which serve to lock or fasten together distinct parts of a structure, as the "key-stone" of an arch, the wedge or piece of wood, metal, &c., which fixes a joint, or a small metal instrument, shaped like a U, used to secure the bands in the process of sewing in bookbinding.

In musical instruments the term "key" is applied in certain wind instruments, particularly of the wood-wind type, to the levers which open and close valves in order to produce various notes, and in keyboard instruments, such as the organ or the pianoforte, to the exterior white or black parts of the levers which either open or shut the valves to admit the wind from the bellows to the pipes or to release the hammers against the strings (see KEYBOARD). It is from this application of the word to these levers in musical instruments that the term is also used of the parts pressed by the finger in typewriters and in telegraphic instruments.

A key is the insignia of the office of chamberlain in a royal household (see CHAMBERLAIN and LORD CHAMBERLAIN). The "power of the keys" (_clavium potestas_) in ecclesiastical usage represents the authority given by Christ to Peter by the words, "I will give unto thee the keys of the kingdom of heaven" (Matt. xvi. 19). This is claimed by the Roman Church to have been transmitted to the popes as the successors of St Peter.

"Key" was formerly the common spelling of "quay," a wharf, and is still found in America for "cay," an island reef or sandbank off the coast of Florida (see QUAY).

The origin of the name Keys or House of Keys, the lower branch of the
legislature, the court of Tynwald, of the Isle of Man, has been much
discussed, but it is generally accepted that it is a particular
application of the word "key" by English- and not Manx-speaking
people. According to A. W. Moore, _History of the Isle of Man_, i.
160 sqq. (1900), in the Manx statutes and records the name of the
house was in 1417 _Claves Manniae et Claves legis_, Keys of Man and
Keys of the Law; but the popular and also the documentary name till
1585 seems to have been "the 24," in Manx _Kiare as feed_. From 1585
to 1734 the name was in the statutes, &c., "the 24 Keys," or simply
"the Keys." Moore suggests that the name was possibly originally due
to an English "clerk of the rolls," the members of the house being
called in to "unlock or solve the difficulties of the law." There is
no evidence for the suggestion that Keys is an English corruption of
_Kiare-as_, the first part of _Kiare as feed_. Another suggestion is
that it is from a Scandinavian word _keise_, chosen.

KEYBOARD, or MANUAL (Fr. _clavier_; Ger. _Klaviatur_; Ital. _tastatura_), a succession of keys for unlocking sound in stringed, wind or percussion musical instruments, together with the case or board on which they are arranged. The two principal types of keyboard instruments are the organ and the piano; their keyboards, although similarly constructed, differ widely in scope and capabilities. The keyboard of the organ, a purely mechanical contrivance, is the external means of communicating with the valves or pallets that open and close the entrances to the pipes. As its action is incapable of variation at the will of the performer, the keyboard of the organ remains without influence on the quality and intensity of the sound. The keyboard of the piano, on the contrary, besides its purely mechanical function, also forms a sympathetic vehicle of transmission for the performer's rhythmical and emotional feeling, in consequence of the faithfulness with which it passes on the impulses communicated by the fingers. The keyboard proper does not, in instruments of the organ and piano types, contain the complete mechanical apparatus for directly unlocking the sound, but only that external part of it which is accessible to the performer.

The first instrument provided with a keyboard was the organ; we must
therefore seek for the prototype of the modern keyboard in connexion
with the primitive instrument which marks the transition between the
mere syrinx provided with bellows, in which all the pipes sounded at
once unless stopped by the fingers, and the first organ in which sound
was elicited from a pipe only when unlocked by means of some
mechanical contrivance. The earliest contrivance was the simple
slider, unprovided with a key or touch-piece and working in a groove
like the lid of a box, which was merely pushed in or drawn out to open
or close the hole that formed the communication between the wind chest
and the hole in the foot of the pipe. These sliders fulfilled in a
simple manner the function of the modern keys, and preceded the groove
and pallet system of the modern organ. We have no clear or trustworthy
information concerning the primitive organ with sliders. Athanasius
Kircher[1] gives a drawing of a small mouth-blown instrument under the
name of _Magraketha_ (_Mashroqitha'_, Dan. iii. 5), and Ugolini[2]
describes a similar one, but with a pair of bellows, as the magrephah
of the treatise _'Arakhin_.[3] By analogy with the evolution of the
organ in central and western Europe from the 8th to the 15th century,
of which we are able to study the various stages, we may conclude that
in principle both drawings were probably fairly representative, even
if nothing better than efforts of the imagination to illustrate a
text.

The invention of the keyboard with balanced keys has been placed by
some writers as late as the 13th or 14th century, in spite of its
having been described by both Hero of Alexandria and Vitruvius and
mentioned by poets and writers. The misconception probably arose from
the easy assumption that the organ was the product of Western skill
and that the primitive instruments with sliders found in 11th century
documents[4] represent the sum of the progress made in the evolution;
in reality they were the result of a laborious effort to reconquer a
lost art. The earliest trace of a balanced keyboard we possess is
contained in Hero's description of the hydraulic organ said to have
been invented by Ctesibius of Alexandria in the 2nd century B.C. After
describing the other parts (see ORGAN), Hero passes on to the sliders
with perforations corresponding with the open feet of the speaking
pipes which, when drawn forward, traverse and block the pipes. He
describes the following contrivances: attached to the slider is a
three-limbed, pivoted elbow-key, which, when depressed, pushes the
slider inwards; in order to provide for its automatic return when the
finger is lifted from the key, a slip of horn is attached by a gut
string to each elbow-key. When the key is depressed and the slider
pushed home, the gut string pulls the slip of horn and straightens it.
As soon as the key is released, the piece of horn, regaining its
natural bent by its own elasticity, pulls the slider out so that the
perforation of the slider overlaps and the pipe is silenced.[5] The
description of the keyboard by Vitruvius Pollio, a variant of that of
Hero, is less accurate and less complete.[6] From evidence discussed
in the article ORGAN, it is clear that the principle of a balanced
keyboard was well understood both in the 2nd and in the 5th century
A.D. After this all trace of this important development disappears,
sliders of all kinds with and without handles doing duty for keys
until the 12th or 13th century, when we find the small portative
organs furnished with narrow keys which appear to be balanced; the
single bellows were manipulated by one hand while the other fingered
the keys. As this little instrument was mainly used to accompany the
voice in simple chaunts, it needed few keys, at most nine or twelve.
The pipes were flue-pipes. A similar little instrument, having tiny
invisible pipes furnished with beating reeds and a pair of bellows
(therefore requiring two performers) was known as the regal. There are
representations of these medieval balanced keyboards with keys of
various shapes, the most common being the rectangular with or without
rounded corners and the T-shaped. Until the 14th century all the keys
were in one row and of the same level, and although the B flat was
used for modulation, it was merely placed between A and B natural in
the sequence of notes. During the 14th century small square additional
keys made their appearance, one or two to the octave, inserted between
the others in the position of our black keys but not raised. An
example of this keyboard is reproduced by J. F. Riaño[7] from a fresco
in the Cistercian monastery of Nuestra Señora de Piedra in Aragon,
dated 1390.

So far the history of the keyboard is that of the organ. The only
stringed instruments with keys before this date were the _organistrum_
and the _hurdy-gurdy_, in which little tongues of wood manipulated by
handles or keys performed the function of the fingers in stopping the
strings on the neck of the instruments, but they did not influence the
development of the keyboard. The advent of the immediate precursors of
the pianoforte was at hand. In the _Wunderbuch_[8] (1440), preserved
in the Grand Ducal Library at Weimar, are represented a number of
musical instruments, all named. Among them are a _clavichordium_ and a
_clavicymbalum_ with narrow additional keys let in between the wider
ones, one to every group of two large keys. The same arrangement
prevailed in a _clavicymbalum_ figured in an anonymous MS. attributed
to the 14th century, preserved in the public library at Ghent[9]; from
the lettering over the jacks and strings, of which there are but
eight, it would seem as though the draughtsman had left the
accidentals out of the scheme of notation. These are the earliest
known representations of instruments with keyboards. The exact date at
which our chromatic keyboard came into use has not been discovered,
but it existed in the 15th century and may be studied in the picture
of St Cecilia playing the organ on the Ghent altarpiece painted by the
brothers Hubert and Jan van Eyck. Praetorius distinctly states that
the large Halberstadt organ had the keyboard which he figures (plates
xxiv. and xxv.) from the outset, and reproduces the inscription
asserting that the organ was built in 1361 by the priest Nicolas Fabri
and was renovated in 1495 by Gregorius Kleng. The keyboard of this
organ has the arrangement of the present day with raised black notes;
it is not improbable that Praetorius's statement was correct, for
Germany and the Netherlands led the van in organ-building during the
middle ages.

At the beginning of the 16th century, to facilitate the playing of
contrapuntal music having a drone bass or _point d'orgue_, the
arrangement of the pipes of organs and of the strings of spinets and
harpsichords was altered, with the result that the lowest octave of
the keyboard was made in what is known as short measure, or mi, ré,
ut, i.e. a diatonic with B flat included, but grouped in the space of
a sixth instead of appearing as a full octave. In order to carry out
this device, the note below F was C, instead of E, the missing D and E
and the B flat being substituted for the three sharps of F, G and A,
and appearing as black notes, thus:--

D E B[flat]
C F G A B C,

or if the lowest note appeared to be B, it sounded as G and the
arrangement was as follows:--

A B
G C D E F G.

This was the most common scheme for the short octave during the 16th
and 17th centuries, although others are occasionally found. Praetorius
also gives examples in which the black notes of the short octave were
divided into two halves, or separate keys, the forward half for the
drone note, the back half for the chromatic semitone, thus:--

F[sharp] G[sharp]
| |
D E B[flat]
C F G A B C

This arrangement, which accomplishes its object without sacrifice, was
to be found early in the 17th century in the organs of the monasteries
of Riddageshausen and of Bayreuth in Vogtland.

KEYSTONE, the central voussoir of an arch (q.v.). The Etruscans and the Romans emphasized its importance by decorating it with figures and busts, and, in their triumphal arches, projected it forward and utilized it as an additional support to the architrave above. Throughout the Italian period it forms an important element in the design, and serves to connect the arch with the horizontal mouldings running above it. In Gothic architecture there is no keystone, but the junction of pointed ribs at their summit is sometimes decorated with a boss to mask the intersection.

KEY WEST (from the Spanish _Cayo Hueso_, "Bone Reef"), a city, port of entry, and the county-seat of Monroe county, Florida, U.S.A., situated on a small coral island (4½ m. long and about 1 m. wide) of the same name, 60 m. S. W. of Cape Sable, the most southerly point of the mainland. It is connected by lines of steamers with Miami and Port Tampa, with Galveston, Texas, with Mobile, Alabama, with Philadelphia and New York City, and with West Indian ports, and by regular schooner lines with New York City, the Bahamas, British Honduras, &c. There is now an extension of the Florida East Coast railway from Miami to Key West (155 m.). Pop. (1880), 9890; (1890), 18,080; (1900), 17,114, of whom 7266 were foreign-born and 5562 were negroes; (1910 census), 19,945. The island is notable for its tropical vegetation and climate. The jasmine, almond, banana, cork and coco-nut palm are among the trees. The oleander grows here to be a tree, and there is a banyan tree, said to be the only one growing out of doors in the United States. There are many species of plants in Key West not found elsewhere in North America. The mean annual temperature is 76° F., and the mean of the hottest months is 82.2° F.; that of the coldest months is 69° F.; thus the mean range of temperature is only 13°. The precipitation is 35 in.; most of the rain falls in the "rainy season" from May to November, and is preserved in cisterns by the inhabitants as the only supply of drinking water. The number of cloudy days per annum averages 60. The city occupies the highest portion of the island. The harbour accommodates vessels drawing 27 ft.; vessels of 27-30 ft. draft can enter by either the "Main Ship" channel or the south-west channel; the south-east channel admits vessels of 25 ft. draft or less; and four other channels may be used by vessels of 15-19 ft. draft. The harbour is defended by Fort Taylor, built on the island of Key West in 1846, and greatly improved and modernized after the Spanish-American War of 1898. Among the buildings are the United States custom house, the city hall, a convent, and a public library.

In 1869 the insignificant population of Key West was greatly increased by Cubans who left their native island after an attempt at revolution; they engaged in the manufacture of tobacco, and Key West cigars were soon widely known. Towards the close of the 19th century this industry suffered from labour troubles, from the competition of Tampa, Florida, and from the commercial improvement of Havana, Cuba; but soon after 1900 the tobacco business of Key West began to recover. Immigrants from the Bahama Islands form another important element in the population. They are known as "Conchs," and engage in sponge fishing. In 1905 the value of factory products was $4,254,024 (an increase of 37.7% over the value in 1900); the exports in 1907 were valued at $852,457; the imports were valued at $994,472, the excess over the exports being due to the fact that the food supply of the city is derived from other Florida ports and from the West Indies.

According to tradition the native Indian tribes of Key West, after being almost annihilated by the Caloosas, fled to Cuba. There are relics of early European occupation of the island which suggest that it was once the resort of pirates. The city was settled about 1822. The Seminole War and the war of the United States with Mexico gave it some military importance. In 1861 Confederate forces attempted to seize Fort Taylor, but they were successfully resisted by General William H. French.

KHABAROVSK (known as KHABAROVKA until 1895), a town of Asiatic Russia, capital of the Amur region and of the Maritime Province. Pop. (1897), 14,932. It was founded in 1858 and is situated on a high cliff on the right bank of the Amur, at its confluence with the Usuri, in 48° 28´ N. and 135° 6´ E. It is connected by rail with Vladivostok (480 m.), and is an important entrepôt for goods coming down the Usuri and its tributary the Sungacha, as well as a centre of trade, especially in sables. The town is built of wood, and has a large cathedral, a monument (1891) to Count Muraviev-Amurskiy, a cadet corps (new building 1904), a branch of the Russian Geographical Society, with museum, and a technical railway school.

KHAIRAGARH, a feudatory state in the Central Provinces, India. Area, 931 sq. m.; pop. (1901), 137,554, showing a decrease of 24% in the decade due to the effects of famine; estimated revenue, £20,000; tribute £4600. The chief, who is descended from the old Gond royal family, received the title of raja as an hereditary distinction in 1898. The state includes a fertile plain, yielding rice and cotton. Its prosperity has been promoted by the Bengal-Nagpur railway, which has a station at Dongargarh, the largest town (pop. 5856), connected by road with Khairagarh town, the residence of the raja.

KHAIREDDIN (_Khair-ed-Din_ = "Joy of Religion") (d. 1890), Turkish statesman, was of Circassian race, but nothing is known about his birth and parentage. In early boyhood he was in the hands of a Tunisian slave-dealer, by whom he was sold to Hamuda Pasha, then bey of Tunis, who gave him his freedom and a French education. When Khaireddin left school the bey made him steward of his estates, and from this position he rose to be minister of finance. When the prime minister, Mahmud ben Ayad, absconded to France with the treasure-chest of the beylic, Hamuda despatched Khaireddin to obtain the extradition of the fugitive. The mission failed; but the six years it occupied enabled Khaireddin to make himself widely known in France, to become acquainted with French political ideas and administrative methods, and, on his return to Tunisia, to render himself more than ever useful to his government. Hamuda died while Khaireddin was in France, but he was highly appreciated by the three beys--Ahmet (1837), Mohammed (1855), and Sadok (1859)--who in turn followed Hamuda, and to his influence was due the sequence of liberal measures which distinguished their successive reigns. Khaireddin also secured for the reigning family the confirmation from the sultan of Turkey of their right of succession to the beylic. But although Khaireddin's protracted residence in France had imbued him with liberal ideas, it had not made him a French partisan, and he strenuously opposed the French scheme of establishing a protectorate over Tunisia upon which France embarked in the early 'seventies. This rendered him obnoxious to Sadok's prime minister--an apostate Jew named Mustapha ben Ismael--who succeeded in completely undermining the bey's confidence in him. His position thus became untenable in Tunisia, and shortly after the accession of Abdul Hamid he acquainted the sultan with his desire to enter the Turkish service. In 1877 the sultan bade him come to Constantinople, and on his arrival gave him a seat on the Reform Commission then sitting at Tophane. Early in 1879 the sultan appointed him grand vizier, and shortly afterwards he prepared a scheme of constitutional government, but Abdul Hamid refused to have anything to do with it. Thereupon Khaireddin resigned office, on the 28th of July 1879. More than once the sultan offered him anew the grand vizierate, but Khaireddin persistently refused it, and thus incurred disfavour. He died on the 30th of January 1890, practically a prisoner in his own house.

KHAIRPUR, or KHYRPOOR, a native state of India, in the Sind province of Bombay. Area, 6050 sq. m.; pop. (1901), 199,313, showing an apparent increase of 55% in the decade; estimated revenue, £90,000. Like other parts of Sind, Khairpur consists of a great alluvial plain, very rich and fertile in the neighbourhood of the Indus and the irrigation canals, the remaining area being a continuous series of sand-hill ridges covered with a stunted brushwood, where cultivation is altogether impossible. A small ridge of limestone hills passes through the northern part of the state, being a continuation of a ridge known as the Ghar, running southwards from Rohri. The state is watered by five canals drawn off from the Indus, besides the Eastern Nara, a canal which follows an old bed of the Indus. In the desert tracts are pits of _natron_.

KHAIRPUR town is situated on a canal 15 m. E. of the Indus, with a railway station, 20 m. S. of Sukkur, on the Kotri-Rohri branch of the North-Western railway, which here crosses a corner of the state. Pop. (1901), 14,014. There are manufactures of cloth, carpets, goldsmiths' work and arms, and an export trade in indigo, grain and oilseeds.

The chief, or mir, of Khairpur belongs to a Baluch family, known as
the Talpur, which rose on the fall of the Kalhora dynasty of Sind.
About 1813, during the troubles in Kabul incidental to the
establishment of the Barakzai dynasty, the mirs were able to withhold
the tribute which up to that date had been somewhat irregularly paid
to the rulers of Afghanistan. In 1832 the individuality of the
Khairpur state was recognized by the British government in a treaty
under which the use of the river Indus and the roads of Sind were
secured. When the first Kabul expedition was decided on, the mir of
Khairpur, Ali Murad, cordially supported the British policy; and the
result was that, after the battles of Meeanee and Daba had put the
whole of Sind at the disposal of the British, Khairpur was the only
state allowed to retain its political existence under the protection
of the paramount power. The chief mir, Faiz Mahommed Khan, G.C.I.E.,
who was an enlightened ruler, died in 1909, shortly after returning
from a pilgrimage to the Shiite shrine of Kerbela.

KHAJRAHO, a village of Central India, in the state of Chhatarpur, famous for its old temples; pop. (1901), 1242. It is believed to have been the capital of the ancient kingdom of Jijhoti, corresponding with modern Bundelkhand. The temples consist of three groups: Saiva, Vaishnav and Jain, almost all built in the 10th and 11th centuries. They are covered outside and inside with elaborate sculptures, and also bear valuable inscriptions.

KHAKI (from Urdu _khak_, dust), originally a dust-coloured fabric, of the character of canvas, drill or holland, used by the British and native armies in India. It seems to have been first worn by the Guides, a mixed regiment of frontier troops, in 1848, and to have spread to other regiments during the following years. Some at any rate of the British troops had uniforms of khaki during the Indian Mutiny (1857-58), and thereafter drill or holland (generally called "khaki" whatever its colour) became the almost universal dress of British and native troops in Asia and Africa. During the South African War of 1899-1902, drill of a sandy shade of brown was worn by all troops sent out from Great Britain and the Colonies. Khaki drill, however, proved unsuitable material for the cold weather in the uplands of South Africa, and after a time the troops were supplied with dust-coloured serge uniforms. Since 1900 all drab and green-grey uniforms have been, unofficially at any rate, designated khaki.

KHALIFA, THE. ABDULLAH ET TAAISHA (Seyyid Abdullah ibn Seyyid Mahommed) (1846-1899), successor of the mahdi Mahommed Ahmed, born in 1846 in the south-western portion of Darfur, was a member of the Taaisha section of the Baggara or cattle-owning Arabs. His father, Mahommed et Taki, had determined to emigrate to Mecca with his family; but the unsettled state of the country long prevented him, and he died in Africa after advising his eldest son, Abdullah, to take refuge with some religious sheikh on the Nile, and to proceed to Mecca on a favourable opportunity. Abdullah, who had already had much connexion with slave-hunters, and had fought against the Egyptian conquest of Darfur, departed for the Nile valley with this purpose; hearing on the way of the disputes of Mahommed Ahmed, who had not yet claimed a sacred character, with the Egyptian officials, he went to him in spite of great difficulties, and, according to his own statement, at once recognized in him the mahdi ("guide") divinely appointed to regenerate Islam in the latter days. His advice to Mahommed to stir up revolt in Darfur and Kordofan being justified by the result, he became his most trusted counsellor, and was soon declared principal khalifa or vicegerent of the mahdi, all of whose acts were to be regarded as the mahdi's own. The mahdi on his deathbed (1885) solemnly named him his successor; and for thirteen years Abdullah ruled over what had been the Egyptian Sudan. Khartum was deserted by his orders, and Omdurman, at first intended as a temporary camp, was made his capital. At length the progress of Sir Herbert (afterwards Lord) Kitchener's expedition compelled him to give battle to the Anglo-Egyptian forces near Omdurman, where on the 2nd of September 1898 his army, fighting with desperate courage, was almost annihilated. The khalifa, who had not left Omdurman since the death of the mahdi, fled to Kordofan with the remnant of his host. On the 25th of November 1899 he gave battle to a force under Colonel (afterwards General Sir) F. R. Wingate, and was slain at Om Debreikat. He met death with great fortitude, refusing to fly, and his principal amirs voluntarily perished with him.

The khalifa was a man of iron will and great energy, and possessed some military skill. By nature tyrannical, he was impatient of all opposition and appeared to delight in cruelty. It must be remembered, however, that he had to meet the secret or open hostility of all the tribes of the Nile valley and that his authority was dependent on his ability to overawe his opponents. He maintained in public the divine character of the power he inherited from the mahdi and inspired his followers to perform prodigies of valour. Although he treated many of his European captives with terrible severity he never had any of them executed. It is said that their presence in Omdurman ministered to his vanity--one of the most marked features of his character. In private life he showed much affection for his family.

Personal sketches of the khalifa are given in Slatin Pasha's _Fire and
Sword in the Sudan_ (London, 1896), and in Father Ohrwalder's _Ten
Years in the Mahdi's Camp_ (London, 1892). See also Sir F. R.
Wingate's _Mahdiism and the Egyptian Sudan_ (London, 1891).

KHALIL IBN AHMAD [ABU 'ABDURRAHMAN UL-KHALIL IBN AHMAD IBN 'AMR IBN TAMIM] (718-791), Arabian philologist, was a native of Oman. He was distinguished for having written the first Arabic dictionary and for having first classified the Arabic metres and laid down their rules. He was also a poet, and lived the ascetic life of a poor student. His grammatical work was carried on by his pupil Sibawaihi. The dictionary known as the _Kitab-ul-'Ain_ is ascribed, at least in its inception, to Khalil. It was probably finished by one of his pupils and was not known in Bagdad until 862. The words were not arranged in alphabetical order but according to physiological principles, beginning with _'Ain_ and ending with _Ya_. The work seems to have been in existence as late as the 14th century, but is now only known from extracts in manuscript.

Various grammatical works are ascribed to Khalil, but their
authenticity seems doubtful; cf. C. Brockelmann, _Gesch. der
arabischen Literatur_, i. 100 (Weimar, 1898). (G. W. T.)

KHAMGAON, a town of India, in the Buldana district of Berar, 340 m. N.E. of Bombay. Pop. (1901), 18,341. It is an important centre of the cotton trade. The cotton market, the second in the province, was established about 1820. Khamgaon was connected in 1870 with the Great Indian Peninsula railway by a short branch line.

KHAMSEH, a small but important province of Persia, between Kazvin and Tabriz. It consisted formerly of five districts, whence its name Khamseh, "the five," but is now subdivided into seventeen districts. The language of the inhabitants is Turkish. The province pays a revenue of about £20,000 per annum, and its capital is Zenjan.

KHAMSIN (Arabic for "fifty"), a hot oppressive wind arising in the Sahara. It blows in Egypt at intervals for about fifty days during March, April and May, and fills the air with sand. In Guinea the wind from the Sahara is known as harmattan (q.v.).

KHAMTIS, a tribe of the north-east frontier of India, dwelling in the hills bordering the Lakhimpur district of Assam. They are of Shan origin, and appear to have settled in their present abode in the middle of the 18th century. In 1839 they raided the British outpost of Sadiya, but they have since given no trouble. Their headquarters are in a valley 200 m. from Sadiya, which can be reached only over high passes and through dense jungle. In 1901 the number of speakers of Khamti was returned as only 1490, mostly in Burma.

KHAN (from the Turki, hence Persian and Arabic _Khan_), a title of respect in Mahommedan countries. It is a contracted form of _khaqan_ (khakan), a word equivalent to sovereign or emperor, used among the Mongol and Turki-nomad hordes. The title khan was assumed by Jenghis when he became supreme ruler of the Mongols; his successors became known in Europe as the Great Khans (sometimes as the Chams, &c.) of Tatary or Cathay. Khan is still applied to semi-independent rulers, such as the khans of Russian Turkestan, or the khan of Kalat in Baluchistan, and is also used immediately after the name of rulers such as the sultan of Turkey; the meaning of the term has also extended downwards, until in Persia and Afghanistan it has become an affix to the name of any Mahommedan gentleman, like Esquire, and in India it has become a part of many Mahommedan names, especially when Pathan descent is claimed. The title of Khan Bahadur is conferred by the British government on Mahommedans and also on Parsis.

KHANDESH, EAST and WEST, two districts of British India, in the central division of Bombay. They were formed in 1906 by the division of the old single district of Khandesh. Their areas are respectively 4544 sq. m. and 5497 sq. m., and the population on these areas in 1901 was 957,728 and 469,654. The headquarters of East Khandesh are at Jalgaon, and those of West Khandesh at Dhulia.

The principal natural feature is the Tapti river, which flows through both districts from east to west and divides each into two unequal parts. Of these the larger lie towards the south, and are drained by the rivers Girna, Bori and Panjhra. Northwards beyond the alluvial plain, which contains some of the richest tracts in Khandesh, the land rises towards the Satpura hills. In the centre and east the country is level, save for some low ranges of barren hills, and has in general an arid, unfertile appearance. Towards the north and west, the plain rises into a difficult and rugged country, thickly wooded, and inhabited by wild tribes of Bhils, who chiefly support themselves on the fruits of the forests and by wood-cutting. The drainage of the district centres in the Tapti, which receives thirteen principal tributaries in its course through Khandesh. None of the rivers is navigable, and the Tapti flows in too deep a bed to be useful for irrigation. The district on the whole, however, is fairly well supplied with surface water. Khandesh is not rich in minerals. A large area is under forest; but the jungles have been denuded of most of their valuable timber. Wild beasts are numerous. In 1901 the population of the old single district was 1,427,382, showing an increase of less than 1% in the decade. Of the aboriginal tribes the Bhils are the most important. They number 167,000, and formerly were a wild and lawless robber tribe. Since the introduction of British rule, the efforts made by kindly treatment, and by the offer of suitable employment, to win the Bhils from their disorderly life have been most successful. Many of them are now employed in police duties and as village watchmen. The principal crops are millets, cotton, pulse, wheat and oilseeds. There are many factories for ginning and pressing cotton, and a cotton-mill at Jalgaon. The eastern district is traversed by the Great Indian Peninsula railway, which branches at Bhusawal (an important centre of trade) towards Jubbulpore and Nagpur. Both districts are crossed by the Tapti Valley line from Surat. Khandesh suffered somewhat from famine in 1896-1897, and more severely in 1899-1900.
