2. _Wellsburg, Chemung County._—In 1793 (Mem. Amer. Acad. Arts, Sci., vol. II, pt. 1, p. 164), Timothy Edwards reported a horn or bone of some animal had been found in Chemung, or Tyoga, River, about 12 miles from Tyoga Point. Mr. F. W. Ashley, of the Library of Congress, informed the writer that Tyoga Point was a former name of the present town of Athens, Pennsylvania. Whether the tusk was really found in Pennsylvania or in New York is uncertain, nor is it any more certain that the tusk was that of an elephant and not of a mastodon. The fragment was 6 feet 9 inches long, with a circumference of 21 inches at the base and 15 inches at the other extremity. It was estimated to have formed an arc 10 or 12 feet long of a semicircle. Mather, in 1843 (Geol. 4th Dist., pp. 233, 636), stated that bones of both the mastodon and the elephant had been found in Orange County. On page 44 of the same volume he stated that bones supposed to belong to an elephant had been found 2 miles west of Greenville, in Greene County. Hall regarded them as belonging to a mastodon. The case is doubtful. PENNSYLVANIA. (Map 16.) 1. _Chambersburg, Franklin County._—In 1806 (Phila. Med. and Phys. Jour., vol. II, pt. 1, p. 157), Dr. B. S. Barton reported remains of a mammoth found at Chambersburg. 2. _Pittsburgh, Allegheny County._—In 1875 (Proc. Acad. Natural Sci., Phila., p. 121), Leidy exhibited drawings of an elephant tooth, dredged up at the confluence of the Allegheny and Monongahela Rivers at Pittsburgh. The tooth was nearly entire and weighed slightly less than 16 pounds. Leidy referred the tooth to _Elephas americanus_, but whether it was _E. primigenius_ or _E. columbi_ can not be determined. 3. _Meadville, Crawford County._—In the Geologist, of London, volume V, 1862, on page 431, it was stated that Mr. A. B. Ruhmond, of Meadville, had reported to the Scientific American the discovery of mammoth remains in the excavation of the Atlantic and Great Western Railroad at French Creek. No further information was furnished. In this case the remains might have been those of a mastodon. 4. _Girard, Erie County._—In the Erie Public Museum are three tusks, said to have been found near Girard; one is about 4 feet long; another somewhat longer. They are slender and probably belonged to _Elephas primigenius_, but there is no certainty about this. OHIO. (Maps 16, 36.) 1. _Little Salt Creek, Jackson County._—Somewhere along this creek was discovered the lower jaw and its teeth, to which was first given the name _Elephas jacksoni_. The creek, with its branches, gathers up the waters of the central part of the county and leaves the county at its northwest corner.
