According to Haymond, another skeleton was found about 3.5 miles northeast of Brookville, in a piece of marshy ground which the owner was ditching. This discovery must have been made either on the outer (Hartwell) moraine of the Wisconsin glacier or along East Honnas Creek, where it breaks through the moraine. In either case, the animal must have been buried there after the retirement of the ice from that moraine.
12. _Dearborn County._—In 1872 (3d and 4th Ann. Rep. Geol. Surv. Indiana, p. 402), Professor R. B. Warder mentioned briefly that some remains of mastodon had been met with in this county. A part of a large pelvis was found at a salt spring on Tanner’s Creek, below Guilford. This may have belonged to either a mastodon or an elephant. A mastodon’s tooth is said to have been found on high ground on George Randall’s farm, 5 miles west of southwest of Aurora, lying on a stratum of blue clay 8 or 9 feet below the surface. This region is occupied by Illinoian drift and the mastodon probably lived there at some time after the Illinoian stage and before the Wisconsin. However, we can not be certain that the animal was not a mammoth, for no description was given of the tooth and it has almost certainly been destroyed.
According to L. C. Ward’s report on the soils of Dearborn County (32d Ann. Rep. Geol. Surv. Indiana, p. 232), this immediate region is occupied by what he calls limestone upland soil, which has resulted from the decay of Silurian limestones and shales. Nothing is said about Illinoian drift there. Nevertheless, by some means, this proboscidean was buried there during the Pleistocene period.
Warder mentioned other remains of proboscideans reported from Ohio County, adjoining Dearborn on the south, a piece of a tusk found near Patriot, a tusk on Laughery Creek above Hartford, and a tooth at Rising Sun, in the river bank; but these may have belonged to elephants. To an elephant may have belonged the tusks which Warder reported as having been found in the river bottom 5 miles below Vevay, in Switzerland County.
54. _Lawrenceburg, Dearborn County._—Mr. M. G. Mock, of Houston, Texas, formerly of Muncie, Indiana, a careful collector of mastodon and elephant teeth, in a letter informed the writer that in August 1887 a large mastodon tooth was found near Lawrenceburg, but the exact locality was not given.
