13. _Wheaton, Du Page County._—In Netta C. Anderson’s list, page 10, it was reported on the authority of Charles A. Blanchard, president of Wheaton College, that about 1890 the remains of a mammoth were found in ditches on the Jewell farm, near Wheaton. The remains consisted of about a dozen ribs, as many vertebræ, a femur, and other parts of legs. It appears to the writer that the remains may have belonged to a mastodon. Wheaton is situated on that part of the Valparaiso moraine which runs parallel with the western shore of Lake Michigan. Whatever the animal was it must be regarded as belonging to the Late Wisconsin stage. 13. _Oak Park, Cook County._—Under this number 13 must be recorded a mammoth tooth found in a gravel-pit at Oak Park, at a depth of several feet. Only parts of it were secured and the species is unknown. The pit was in the Glenville beach, laid down during the waning of the Wisconsin glacial sheet (Baker, F. C., Univ. Ill. Bull. XVII, p. 70). 10. _Evanston, Cook County._—In Netta C. Anderson’s list, page 9, Professor U. S. Grant, of Northwestern University, reported that the museum contains the tooth of a mammoth, taken from a gravel-pit near Evanston. The animal must have lived after the Wisconsin glacier had withdrawn into the basin of Lake Michigan. 11. _Rochelle, Ogle County._—In Netta C. Anderson’s list, pages 15, 16, Professor Frank Leverett reported that in July 1886 he had seen a collection of mammoth fossils at the house of F. G. Rossman, a farmer living near Rochelle, which he had obtained in a bog in the northwestern part of section 33, Lynnville Township. The materials consisted of a tusk, two teeth, a piece of the jawbone, a few ribs, and some fragments of bones. The fragment of tusk was about 5 feet long, 20 inches in circumference at one end, about 18 inches at the other. The tooth was from 12 to 13 inches long and 4 inches wide. Rochelle is on the border between the Wisconsin drift-sheet and the earlier one lying west of it. On Leverett’s map this is put down as being Iowan; but no Iowan is now recognized in Illinois. Mr. F. N. Rice, county surveyor, reported that Lynnville Township is number 41 north, range 2 west. IN THE UNGLACIATED REGION IN THE NORTHWEST CORNER OF THE STATE. 12. _Galena, Jo Daviess County._—The geologist J. D. Whitney reported in 1866 (Geol. Surv. Illinois, vol. I, p. 162) that a few teeth of the elephant had been found near Galena, on the surface. These are said to be preserved in a collection in Galena. Whitney stated that these were all that he had met with in the lead region. In his Geology of the Lead Region (Wisconsin Geol. Surv., vol. I, pp. 129–133) the same author said that, so far as he knew, elephant remains never were found in the lead crevices. The teeth mentioned above had been found within the limits of the city of Galena. Galena is situated in the driftless region and no conclusion is reached about the geological age of those teeth.
