In Heidelberg University, Tiffin, Ohio, the writer examined teeth and bones of two mastodons which had been found in Auglaize County, but the exact localities were not known.
31. _Ohio City, Van Wert County._—In 1848 (Amer. Jour. Sci., ser. 2, vol. V, p. 215), Whittlesey stated that a mastodon tooth had been found at this place, and further, that it had been mentioned by Charles Lyell. It was found in alluvium and rested on a blue marl. The locality is in the vicinity of the Lima moraine.
32. _Columbus Grove, Putnam County._—In 1913, Mr. H. B. Maple, of this town, sent to the U. S. National Museum for identification a lower left first molar, found in gravel 3 miles north of the town, near the border of ancient Lake Maumee.
33. _Liberty Township, Putnam County._—In 1874, Professor N. H. Winchell (Geol. Surv. Ohio, vol. II, pt. 1, p. 392) told of the finding of large bones, supposed to belong to a mastodon, just southeast of the center of section 6, in draining the Medary marsh, in the township named (Tp. 2 N., R. 7 E.) The bones were in a sandy loam along the north side of the Leipsic ridge, a part of the Defiance moraine. Another was found in section 8 of the same township. The remains consisted of two teeth, bones of the posterior extremities, and a fragment of a tusk. The limb-bone was removed 23 feet from the tusk. These remains lay at a depth of about 3 feet from the surface. Other large bones, mastodon or elephant, were found in section 7, Ottawa Township (Tp. 1 N., R. 7 E.). This was evidently on the south side of the ridge mentioned, but yet probably north of Blanchard River.
34. _Springfield Township, Lucas County._—In 1873 (Geol. Surv. Ohio, vol. I, pt. 1, p. 556), Dr. G. K. Gilbert wrote that Dr. J. B. Trembley, of Toledo, had informed him that a tooth of a mastodon had been obtained from a marsh in Springfield, Lucas County. It is probable that Gilbert meant Springfield Township. He could not ascertain the exact locality, but he remarked that all the marshes of that township date from the formation of the lowest and most recent of the raised beaches and that it was almost certain that the tooth is not less recent than they. Springfield Township is nearly in the center of this county.
