There is no reason to suppose that the mastodon in question lived before the Wisconsin stage, but at its close. The ice must already have retired beyond the State, and the land, which, according to Dr. Fairchild, was depressed at the latitude of Shrewsbury about 350 feet, must have been elevated enough to reduce considerably the area covered by water before conditions would have favored the presence of mastodon. It is possible, however, that the depression was not so great. CONNECTICUT. (Maps 5, 6.) 1. _Cheshire, New Haven County._—In 1828 (Amer. Jour. Sci., vol. XIV, p. 187), a note appeared which stated that in the summer of the preceding year 3 or 4 large molar teeth of a “mammoth” had been found near Cheshire. From the description it is evident that they were teeth of a mastodon. They were in fine condition but were immediately destroyed in a frolic of the workmen. The teeth had been found in gravel only a few feet under ground. Warren (“Monogr. on _Mastodon giganteus_,” p. 3) stated that the mastodon teeth had been found in making a canal at Cheshire. He undoubtedly referred to the teeth mentioned above. Schuchert (Amer. Jour. Sci., ser. 4, vol. XIV, p. 321) states that one tooth was preserved and is now in the Yale University collection. 2. _New Britain, Hartford County._—In 1835 (Amer. Jour. Sci., vol. XXVII, p. 165), a report was published about the finding of a vertebra of a mastodon in digging a canal for a factory in Berlin, not far from New Britain. It appears to have been met with in a deposit of marl. Schuchert (op. cit., p. 322) mentions this find and says that the locality was not in Berlin, but in New Britain. The depth is given as 3 feet and the material as mud or clay. Schuchert, as cited, gave an account of the discovery, in 1852, of another mastodon in New Britain. Two or three teeth and some bones were found in a soft swampy soil.
