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.

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.

1. Stockholm, Pepin County.—All that is known regarding the occurrence of an elephant at this place was published by Professor N. H. Winchell in 1910 (Bull. Minn. Acad. Sci., vol. IV, p. 417), as follows: “Capt. Jos. Buisson stated that a mammoth tooth was found opposite Lake City, near Stockholm, on the shore of Lake Pepin.” The tooth may have been that of a mastodon.
