Dr. J. C. Warren (“Monogr. on _Mastodon giganteus_,” ed. 2, 1855, p. 162, plate XXVIII, fig. B) figured and described the tooth. The length was given as 11 inches at the base, and the number of ridge-plates as 22. This would give an average of 8 plates in a 100–mm. line. This number and the general appearance of the tooth indicate that the animal was _Elephas columbi_, instead of _E. primigenius_. The difference between this tooth and that of _E. primigenius_ is well shown by the figure of a tooth of _E. primigenius_ from Zanesville, Ohio, figured on the same plate with the Vermont tooth. This tooth is now in the American Museum at New York. Thompson reported the presence of many billets of wood, about 18 inches long, in the bottom of the muck, the work of beavers. At the Davenport (Iowa) Academy of Natural Science the writer examined a tooth of an elephant labeled as having been found on Mount Holly in excavating for the Vermont Central Railroad. The length along the base is 300 mm., the height of the ninth plate is 160 mm., the length of the grinding-surface 160 mm. There are in all 24 plates, the 10 anterior ones of which are worn. There are 7 ridge-plates in a 100–mm. line, measured on one side of the tooth. This tooth is regarded as belonging to _Elephas columbi_; it certainly belonged to another individual than the one that Warren figured. It is almost certain that the animals represented by the teeth and skeletal remains found on Mount Holly lived after the retreat of the ice from those mountains; and one may suppose that local glaciers lingered long after the main ice-front had abandoned the region. The animals lived certainly as late as near the close of the Pleistocene, if not at the beginning of the Recent; they may have been living on those mountains while the basin of Lake Champlain was an arm of the sea. NEW YORK. (Map 12.) 1. _Homer, Cortland County._—In 1847 (Amer. Jour. Agric. and Sci., vol. VI, p. 31, fig.), Samuel Woolworth reported that an elephant tooth had been found on the bank of a small stream, about 2 miles northwest of Homer. Emmons, in 1858 (Geol. Surv. North Carolina, East. Cos., p. 200), figured the same tooth. In his Manual of Geology (ed. 2, 1860, p. 242, fig. 207) he stated that this tooth was found in Cortland County. Henry A. Ward, of Rochester, advertised and sold casts of this elephant tooth, as the writer is informed by Mr. Frank H. Ward, of Ward’s Natural Science Establishment. It is almost certain that this elephant lived in the neighborhood of Homer after the Wisconsin glacial ice had begun its retreat to the far north.
