24. _Roundhead, Hardin County._—In 1875 (Cin. Quart. Jour. Sci., vol. II, p. 153), J. H. Klippart reported that considerable parts of the skeleton of a mastodon had been exhumed at Fort McArthur, in Hardin County, having evidently drifted out to the Scioto marsh and being widely scattered. Fort McArthur does not appear on recent maps; a gazetteer of 1835 locates the place in Logan County, 24 miles north of Urbana. The locality appears to be in the neighborhood of Roundhead and in the marshes in which Scioto and Miami Rivers take their rise. 25. _Washington Township, Auglaize County._—In Bulletin No. 16 of the Geological Survey of Ohio, 1912, page 38, Mr. Alfred Dachnowski, quoting from C. W. Williamson, stated that in 1878 Mr. S. Craig, while engaged in surveying section 19 of Washington Township (Tp. 6 S., R. 5 E.) discovered a mastodon skeleton. No further search had been made in 1905 (Williamson’s Hist. West. Ohio and Auglaize County, p. 336). While doubtless a proboscidean was buried there, one can not be sure that it was not an elephant. This place is not far from New Knoxville. 26. _Pusheta Township, Auglaize County._—From the same authorities it is learned that in 1894 a mastodon calf was discovered in section 29 of the township named (Tp. 6 S., R. 6 E.), embedded in a layer of muck at the bottom of a circular pond. The skeleton is reported as having been quite complete, but it went to pieces as it dried. The tusks were about 1 foot long. At this place the waters flow into Clear Creek, a branch of Auglaize River. 27. _Wapakoneta, Auglaize County._—The authorities quoted reported that a mastodon had been discovered in a ditch excavation in section 33 of Duchouquet Township (Tp. 5 S., R. 6 E.), not far from Wapakoneta. The remains crumbled on exposure and drying. They may have been those of an elephant. 28. _Duchouquet Township, Auglaize County._—The authorities on whom reliance is here put state that in 1891 a mastodon was discovered by some laborers who were deepening and widening the bed of a creek which extends through section 22 of the township mentioned. This creek must have been either Auglaize River or a branch of it, so unimportant that it is not down on the topographical sheet of that quadrangle. The tusks extended across the creek and were cut off by the workmen and carried away.
