From Mr. C. G. Shatzer, of Wittenberg College, in reply to an inquiry, the present writer has received the information that this mastodon is now mounted and in the collection of the Ohio State University at Columbus. It was found at the edge of a small marsh, on the farm of Mr. N. S. Conway, on or close to the line between Clark and Champaign counties, and about 4.5 miles southwest of Mechanicsburg. This would be apparently about a mile northwest of Catawba and in the hills east of Buck Creek. Mr. Shatzer stated that it is in a rather strong knob-and-kettle country. This is shown, too, by the topographical sheet of the region. The writer has examined this mastodon. The tusks measure, following the curve, 9 feet 8 inches in length. At the base of one of them one diameter is 162 mm.; the other, 184 mm. The tusks are somewhat spirally curved. The animal was not aged, inasmuch as the second true molar is worn only on the first crest, and the third molar is not at all worn. 49. _Brighton, Clark County._—Mr. Shatzer reports that in 1905 or 1906 he excavated a mastodon at a point about 5 miles southeast of the place where the other was found and about a mile due north of the village of Brighton. This skeleton was met in a marsh and lay at a depth of about 18 inches, but one fore-leg went straight down into the blue clay. The tusks were badly decayed, but many of the bones were well preserved. 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.
