4. _Sangamon County._—In 1873, Worthen (Geol. Surv. Illinois, vol. V, p. 308) stated that the tooth of a mammoth had been found some years before in the bluffs of the Sangamon River and near the surface. He concluded that it had not come from beds older than the loess. While the probability is that the tooth was found in the Sangamon loess, there can be no certainty about it. The animal might have lived there while the Wisconsin ice was nearby.
5. _Fulton County._—In Netta C. Anderson’s list of 1905 (Augustana Library Pubs. No. 5, p. 10), Professor Albert Hurd, of Knox College, reported that there was in the museum of that college a poorly preserved tooth of some species of elephant, found in Fulton County. All that can be said about the geological age of this find is that the county is covered by Illinoian drift and that the tooth is probably not older. Nevertheless, it might have been found in some excavation or along some ravine which had reached the Yarmouth.
6. _Galesburg, Knox County._—In Netta C. Anderson’s list referred to, page 14, Professor Albert Hurd reported there was in the cabinet of Knox College a much decayed elephant tooth, found near Galesburg in the making of a ditch. The presumption is that the ditch had not passed through the Illinoian drift and that the animal had lived after the Illinoian stage; it may be during the Sangamon stage.
14. _Pekin, Tazewell County._—In 1909 (Bull. 506, U. S. Geol. Surv., p. 61), Dr. J. A. Udden reported remains of a proboscidean found in Adam Saal’s gravel-pit, between Illinois River and Dead Lake, a mile south of Pekin, at a depth of 18 feet. There were two tusks, two teeth, a part of a jaw, and a few other bones. One tooth is reported to have weighed 18 pounds, the other 8 pounds. These were doubtless weighed while wet. Only the teeth of an elephant would weigh so much. It is impossible to determine the species. Udden stated that the gravel probably belongs to the latest Wisconsin terrace. The locality is on the border of the Shelbyville moraine.
9. _Peoria, Peoria County._—In 1873 (Geol. Surv. Illinois, vol. V, p. 237), A. H. Worthen reported two molar teeth, with a portion of the jaw, found in a gravel-bed in the bluff in the city of Peoria. A part of one of these teeth was then in the State Cabinet at Springfield. According to Worthen, these remains were found at a depth between 12 and 48 feet. According to Udden’s map (Bull. U. S. Geol. Surv., 506, plate I) the locality would probably be on the early Wisconsin terrace. The animal must have lived during the formation of this terrace. It would seem that this must have been after the Wisconsin ice had begun to retire and while the region was yet much depressed. Baker (Univ. Ill. Bull. XVII, p. 299) stated that this animal was a mastodon.
