9. _Noblesville, Hamilton County._—John Collett, in the report cited in the last paragraph, on page 385, gave a detailed account of the finding of some remains of a mammoth 4 miles southeast of Noblesville, on the farm of John H. Caylor. The locality is given as on the east half of the northeast quarter of section 16, township 18, range 9 west; but evidently the range is 5 east. In the summer of 1880 a large ditch was being made for the drainage of a swamp, situated, according to Collett, in a valley 20 rods wide and extending several miles from southeast to nearly northwest. The higher land on each side is glacial drift and contains gravel and large boulders. The ditch was 4 feet deep, 3 feet of which was in recent peat or bog, and the bottom extended down 1 foot into fine blue clay. In this clay were found two well-preserved teeth of a mammoth, a hip bone, a thigh bone, and the tips of two vertebræ. These bones and teeth were scattered along the line of the ditch a distance of 80 feet and in a width of less than 2 feet. What became of these bones we are not informed. According to Leverett’s map, this region is covered by Wisconsin ground moraine. I am informed by Professor Leverett that the valley mentioned by Collett was probably originally a subglacial drainage channel. 15. _Muncie, Delaware County._—M. G. Mock, of Houston, Texas, formerly of Muncie, Indiana, showed the writer a sketch of an elephant tooth, a lower hindermost molar, with considerable parts of the skeleton, found on the farm of S. N. Priddy, July 1, 1895. The tooth was 12 inches long and 5 inches across. This belonged probably to _Elephas columbi_, but of this there is no certainty. 10. _Dora, Wabash County._—Elrod and Benedict, in 1892 (17th Ann. Rep. Indiana Geol. Surv., p. 241), reported two large teeth of a mammoth found on the farm of John H. Peffley, in the east half of the southwest quarter of section 18, township 27, range 8 east. The writers of the report saw one of the teeth and identified it as _Elephas primigenius_; but probably they did not consider the differences between this species and _E. columbi_. IN AREA NORTH OF WABASH RIVER. 11. _Jasper County._—John Collett (12th Ann. Rep. Indiana Geol. Surv., p. 73) reported that mammoth remains had been found in Jasper County. Nothing was added. 12. _Pleasant Township, Wabash County._—Elrod and Benedict, as noted above, state on their page 240 that some years previously mammoth bones had been discovered while throwing up an embankment for a bridge across Silver Creek. The bones were found under 5 feet of muck. We have no assurance that these bones were not those of a mastodon. It was reported to Elrod and Benedict that some were in Wabash College, at Crawfordsville. On this same creek, near Laketon, were found some mastodon remains, for which see page 98. This township, in the northwestern corner of Wabash County, lies on the great moraine which runs along the north side of Eel River.
