29. _St. Johns, Auglaize County._—Mastodons have been reported from two localities near the village of St. Johns and along the headwaters of Willow Creek. The one nearest the village is mentioned in Dachnowski’s work “Peat Deposits of Ohio” (Bull. 16, Geol. Surv. Ohio, 1912, p. 38). It was found in section 4 of Clay Township (Tp. 6 S., R. 7 E.), some time about 1870. There is no certainty that the bone did not belong to an elephant. The other mastodon was found in 1870 and accounts of the discovery were given by Dr. G. K. Gilbert (Proc. Lyc. Nat. Hist., N. Y., vol. I, 1871, p. 220; Rep. Geol. Surv. Ohio, vol. I, pt. 1, 1873, p. 556); and by C. W. Williamson (Hist. West. Ohio and Auglaize County, 1905, pp. 334–336). The locality is 2.5 miles east of St. Johns, in section 3, Clay Township. Farmers were engaged in running a broad ditch through a swamp. The depth of the swamp deposit at that point was 8 feet, of which the upper third was peat, the remainder, so far as shown, of marl or marly clay. The bones were in their natural relations and it was evident to Gilbert that the animal had mired there. The lower limb-bones were directed downward and well preserved, but the bones nearer the surface were badly decomposed. The presence of the teeth enabled Gilbert to identify the animal as the mastodon. The peat had evidently been deposited after the death of the animal, which had occurred after the deposit of the drift. Klippart (Cin. Quart. Jour. Sci., vol. II, p. 153) stated that a part of the remains had been placed in the Wapakoneta High School. The remains must have been buried near the Loramie moraine. 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. 30. See page 75. 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.
