390 IVORY AND THE ELEPHANT
much
less than in the tusk at Petrograd already described, is sufficiently
marked to confirm the conclusions above detailed. The "restored" tusks
of the Adams mammoth in the Petrograd Museum have been made up out of
separate pieces and are unquestionably not identical with, or even
similar to, those really borne by this mammoth.
Whatever
may be the final opinion in regard to the permanent value of these
conjectures, they certainly have much to support them, although further
and fuller evidence is needed to establish them satisfactorily.
The
largest tusks of the existing species of elephants in Asia and Africa
are inferior in length to some of those which have been found with
other remains of extinct elephant species. Exceptionally fine examples
of these tusks are now to be seen in New York; Lincoln, Nebraska;
Brunn, Moravia; Los Angeles, California; Mexico City, and also in
Paris, Petrograd, and several other European cities, some of the
American examples coming from our Alaskan territory.
The tusks of the Württemberg mammoth in the Stuttgart Naturaliencabinett are typical specimens of those borne by Elephas primigenius. The
curve is remarkable and yet by no means ungraceful. While the left tusk
measures 8 ft. 10j in. along the outside curve, the direct line from
base to tip is only 4 ft. 5| in., less than half the actual length; the
right tusk is 8 ft. 8f in. long, the "chord" being 4 ft. 3| in. The
circumferences are 26 in. for the right tusk and 25§ in. for the left
one. Besides these tusks, forming part of the splendid skeleton set up
in this institution, there are two remarkable tusks, also from
Steinheim-on-the-Murr, Württemberg, found in 1912. One of these, a left
tusk of the Elephas antiquus, is almost straight, after an initial downward curve, and measures 12 ft. 3 in. in length; the other, a right tusk of Elephas primigenius, has a length along the outside curve of 12 ft. If in., but is so sharply curved
