and flexible that excellent riding-whips have been cut longitudinally from whole tusks. The size to which tusks grow and are brought to market depends on race rather than on size of elephants. The latter run largest in equatorial Africa. Asiatic bull elephant tusks seldom exceed 50 ℔ in weight, though lengths of 9 ft. and up to 150 ℔ weight are not entirely unknown. Record lengths for African tusks are the one presented to George V., when prince of Wales, on his marriage (1893), measuring 8 ft. 712 in. and weighing 165 ℔, and the pair of tusks which were brought to the Zanzibar market by natives in 1898, weighing together over 450 ℔. One of the latter is new in the Natural History Museum at South Kensington; the other is in Messrs Rodgers & Co.’s collection at Sheffield. For length the longest known are those belonging to Messrs Rowland Ward, Piccadilly, which measure 11 ft. and 11 ft. 5 in. respectively, with a combined weight of 293 ℔. Osteodentine, resulting from the effects of injuries from spearheads or bullets, is sometimes found in tusks. This formation, resembling stalactites, grows with the tusk, the bullets or iron remaining embedded without trace of their entry.
The most important commercial distinction of the qualities of ivory is that of the hard and soft varieties. The terms are difficult to define exactly. Generally speaking, hard or bright ivory is distinctly harder to cut with the saw or other tools. It is, as it were, glassy and transparent. Soft contains more moisture, stands differences of climate and temperature better, and does not crack so easily. The expert is guided by the shape of the tooth, by the colour and quality of the bark or skin, and by the transparency when cut, or even before, as at the point of the tooth. Roughly, a line might be drawn almost centrally down the map of Africa, on the west of which the hard quality prevails, on the east the soft. In choosing ivory for example for knife-handles—people rather like to see a pretty grain, strongly marked; but the finest quality in the hard variety, which is generally used for them, is the closest and freest from grain. The curved or canine teeth of the hippopotamus are valuable and come in considerable quantities to the European markets. Owen describes this variety as “an extremely dense, compact kind of dentine, partially defended on the outside by a thin layer of enamel as hard as porcelain; so hard as to strike fire with steel.” By reason of this hardness it is not at all liked by the turner and ivory workers, and before being touched by them the enamel has to be removed by acid, or sometimes by heating and sudden cooling, when it can be scaled off. The texture is slightly curdled, mottled or damasked. Hippo ivory was at one time largely used for artificial teeth, but now mostly for umbrella and stick-handles; whole (in their natural form) for fancy door-handles and the like. In the trade the term is not “riverhorse” but “seahorse teeth.” Walrus ivory is less dense and coarser than hippo, but of fine quality—what there is of it, for the oval centre which has more the character of coarse bone unfortunately extends a long way up. At one time a large supply came to the market, but of late years there has been an increasing scarcity, the animals having been almost exterminated by the ruthless persecution to which they have been subjected in their principal haunts in the northern seas. It is little esteemed now, though our ancestors thought highly of it. Comparatively large slabs are to be found in medieval sculpture of the 11th and 12th centuries, and the grips of most oriental swords, ancient and modern, are made from it. The ivory from the single tusk or horn of the narwhal is not of much commercial value except as an ornament or curiosity. Some horns attain a length of 8 to 10 ft., 4 in. thick at the base. It is dense in substance and of a fair colour, but owing to the central cavity there is little of it fit for anything larger than napkin-rings.
Ivory in Commerce, and its Industrial Applications.—Almost the whole of the importation of ivory to Europe was until recent years confined to London, the principal distributing mart of the world. But the opening up of the Congo trade has placed the port of Antwerp in a position which has equalled and, for a time, may surpass that of London. Other important markets are Liverpool and Hamburg; and Germany, France and Portugal have colonial possessions in Africa, from which it is imported. America is a considerable importer for its own requirements. From the German Cameroon alone, according to Schilling, there were exported during the ten years ending 1905, 452,100 kilos of ivory. Mr Buxton estimates the amount of ivory imported into the United Kingdom at about 500 tons. If we give the same to Antwerp we have from these two ports alone no less than 1000 tons a year to be provided. Allowing a weight so high as 30 ℔ per pair of tusks (which is far too high, perhaps twice too high) we should have here alone between thirty and forty thousand elephants to account for. It is true that every pair of tusks that comes to the market represents a dead elephant, but not necessarily by any means a slain or even a recently killed one, as is popularly supposed and unfortunately too often repeated. By far the greater proportion is the result of stores accumulated by natives, a good part coming from animals which have died a natural death. Not 20% is live ivory or recently killed; the remainder is known in the trade as dead ivory.
In 1827 the principal London ivory importers imported 3000 cwt. in 1850, 8000 cwt. The highest price up to 1855 was £55 per cwt. At the July sales in 1905 a record price was reached for billiard-ball teeth of £167 per cwt. The total imports into the United Kingdom were, according to Board of Trade returns, in 1890, 14,349 cwt.; in 1895, 10,911 cwt.; in 1900, 9889 cwt.; in 1904, 9045 cwt.
From Messrs Hale & Son’s (ivory brokers, 10 Fenchurch Avenue) Ivory Report of the second quarterly sales in London, April 1906, it appears that the following were offered:—

Hard ivory was scarce. West Coast African was principally of the Gabun description, and some of very fine quality. There was very little inquiry for walrus. The highest prices ranged as follows: Soft East Coast tusks (Zanzibar, Mozambique, Bombay and Siam), 102 to 143 ℔. each £66, 10s. to £75, 10s. per cwt. Billiard-ball scrivelloes, £104 per cwt. Cut points for billiard-balls (318 in. to 238 to 3 in.) £114 to £151 per cwt. Seahorse (for best), 3s. 6d. to 4s. 1d. per ℔. Boars’ tusks, 6d. to 7d. per ℔.
