Mr. Hillis Smith stated that a tooth of an elephant had been thrown out in making the ditch above mentioned. This tooth was in the possession of Mr. E. H. Crane, of Kalamazoo. The species is not known. The mastodons referred to above were mentioned by Lane in his report of 1901, page 253. He also called attention to a list of the mollusks found in the muck beneath one of the mastodons, prepared by Bryant Walker (Nautilus, vol. XI, 1898, p. 121), in which 36 species were named. 8. _Eau Claire, Berrien County._—In the Joint Documents of the House of Representatives of Michigan, session 1841, page 559, Bela Hubbard stated that remains of a mastodon had been found on Paw Paw Creek, Berrien County. Lane (Rep. Geol. Surv. Michigan for 1901, p. 252) stated that there are in the Agricultural College at East Lansing, 6 teeth and half of a lower jaw, found near Eau Claire, and which may be the remains referred to by Hubbard. This appears, however, to be an error. On these teeth are the label: “Found at Eau Claire, Berrien Co., Mich. Found beneath several feet of muck while digging a ditch. B. L. Comstock, Aug. 17, 1896.” The teeth are extraordinarily large; M^3 right is 222 mm. long. The exact places where the remains mentioned were found have not been recorded. For an account of the small glacial lakes which occupied the depressions that existed between the Valparaiso moraine and the shore of Lake Michigan while the latter was yet filled with ice, see Leverett and Taylor’s Monograph No. LIII, pages 225–227. In the deposits of these lakes, but probably long after the glacial ice had retired, were buried the bones of the mastodon and other animals. From Mr. N. A. Wood, of the University of Michigan, the information has been received that a part of a skull of a mastodon was found in making a public ditch about 2 or 3 miles south of Barada. 25. _Galien, Berrien County._—In 1885 (Proc. Bost. Soc. Nat. Hist., vol. V, p. 133), I. A. Lapham reported the discovery of the right ramus of the lower jaw of a mastodon at Terre Coupée. This place has disappeared from the maps; but it is said to have been situated on the railroad, 11 miles west of Niles, not far east of Galien. The jaw was found by Mr. A. H. Taylor, at a depth of 6 feet. It was peculiar in having a supernumerary molar, a seventh. The jaw was again described by Dr. J. C. Warren in 1855 (Amer. Jour. Sci. (2), vol. XIX, pp. 348–353). 9. _Dorr, Allegan County._—A. C. Lane (Rep. Geol. Surv. Michigan for 1901, p. 253) stated that Frank Fleser and others had secured a jawbone of mastodon and several teeth. The place is stated to be 4 miles west of Dorr, probably in the valley of Rabbit River, where it cuts through the Valparaiso moraine.
