52. _Vincennes, Knox County._—At the State University of Colorado, at Boulder, there is an atlas of a mastodon which was taken there by Professor M. M. Ellis, formerly of Vincennes, who stated that this, with other bones, had been found at Vincennes, associated with a skull of a fossil bison.
9. _Knox or Gibson County._—In Blainville’s “Ostéographie des Mammifères,” page 340, it was stated that the lower jaw of a mastodon had been found at some place between Vincennes and New Harmony. The locality would be in either Knox or Gibson County. The valley of the Wabash in all this region is filled with outwash from the Wisconsin glacier, and most probably the animal represented lived during the Wisconsin stage; but our lack of knowledge of the conditions in which the jaw was found forbids any assumption of certainty in our conclusion.
10. _Parke County._—In the Forty-first Annual Report of the State Museum of New York it is reported that there was received, about 1888, the tooth of a mastodon, found in this county, at the junction of Raccoon and Little Raccoon Creeks. These creeks unite on section 23 of township 14 north, range 8 west. The political name of the township is Florida. The region is covered by Illinoian drift; hence the tooth is quite certainly more recent than that epoch. The valleys of the creeks named are occupied by outwash from Wisconsin drift, and probably the teeth found lodgment there during the Wisconsin stage.
11. _Brookville, Franklin County._—The writer has given an account of the remains of mastodons found near Brookville (36th Ann. Rep. Geol. Surv. Indiana, 1912, p. 704). The information is derived from a report by Dr. Rufus Haymond, made in the First Annual Report, 1869, page 199. Two of these were found 8 or 9 feet below the surface, in the gravel of the upper terrace, along Whitewater River. One was discovered about half a mile below Brookville, the other about 3.5 miles below the village. According to Mr. A. E. Taylor’s account of this region (34th Ann. Rep. Geol. Surv. Indiana), the terrace in which the mastodon bones were buried is 100 feet above the present bed of Whitewater River. As Haymond speaks of skeletons being found at these localities, it is probable that something more than isolated teeth or bones were buried there. If so, the bones were in their original place of interment, and since that interment the terrace was built up higher by about 8 feet. According to Leverett (Monogr. LIII, p. 118), these terraces were made from the outwash of the Wisconsin glacier while it was forming the moraines which cross Wayne and the southern part of Randolph Counties. If this is true, these mastodons lived shortly after the culmination of the Wisconsin stage. This interpretation would imply that mastodons could live in very close proximity to the glacial front. However, not too much importance must be attached to this case, for it is possible that the animals were not correctly identified.
