16. _Urbana, Champaign County._—In 1908 (Amer. Jour. Sci., ser. 4, vol. XXV, p. 193), Professor R. S. Lull wrote that the Yale University collection has a fairly complete skeleton of a young mastodon from Urbana. The present writer made a note on this specimen to the effect that it was found on a farm 5 miles north of Urbana. This would seem to be not far from Mad River.
50. _Woodstock, Champaign County._—Mr. J. H. Klippart (Cin. Quart. Jour. Sci., vol. II, p. 153) reported that in 1869 a farmer, W. A. Howard, of Woodstock, while ditching in his meadow, dug up a finely preserved femur of a mastodon. For several years this was on exhibition in the State agricultural rooms at Columbus. Unfortunately one can not be sure that the bone was not that of one of the elephants.
30. _Fayette County, near New Holland, Pickaway County._—In 1875 (Cin. Quart. Jour. Sci., vol. II, p. 154), J. H. Klippart reported that portions of a skeleton of a mastodon had been discovered in a bog near New Holland. There appears to be no certainty that the remains were not those of an elephant. They had not been exhumed.
17. _South Bloomfield, Pickaway County._—In 1834 (Amer. Jour. Sci., ser. 1, vol. XXV, p. 256), in an unsigned article, S. P. Hildreth reported the discovery of mastodon teeth and ribs in an excavation for a culvert in a small stream, a mile east of Bloomfield, now called South Bloomfield, where a canal was being constructed. The teeth were in a fine state of preservation. At the same place was found the tooth of an elephant. These remains are said to have been embedded in a black boggy earth.
18. _Circleville, Pickaway County._—In 1820 (Amer. Jour. Sci., vol. II, p. 245), Caleb Atwater stated that a large thigh bone of a mastodon had a short time before been found near the town in digging a mill-race. Here again there must be doubt regarding the identification of the animal.
19. _Pickaway Plains, Pickaway County._—This name is given to a level tract lying about 5 miles southwest of Circleville and east of Scioto River. In the article cited above, Caleb Atwater stated that he had 2 teeth of a mastodon, one of which had been found in a small rivulet near the “Pickaway Plains.” This tooth is illustrated by figures 1 and 2 B, of plate II, of the paper cited. It is evidently a tooth of _Mammut americanum_. The locality would be not far from the broad terminal Wisconsin moraine.
