5. _Pemberton, Burlington County._—Professor E. D. Cope (Cook’s Geol. New Jersey, 1869, p. 740) stated that mastodon remains had been found at Pemberton. Previously, Conrad (Proc. Acad. Nat. Sci., Phila. vol. I, 1832, p. 11) had reported that bones and teeth of this species had been found here. In the collection of the Academy at Philadelphia are a part of a skull and some bones and teeth which were collected at Pemberton in 1887 by J. C. Saltar and E. McConnell. Rhoads (Mamm. Penn. N. J., p. 234) mentioned this skeleton and said that it was exposed in the bed of a small stream. Mr. J. Coleman Saltar, now of Milford, Delaware, has kindly replied to the present writer’s inquiries. He says that the skeleton was found about 1.5 miles northwest of Pemberton, in the bank of a small stream lying partly in the water, partly embedded in the bank. The flood-plain is perhaps about 10 feet below the tilled land along the stream. On the flood-plain is recent silt. Below this appears to be a Pleistocene deposit which contains vegetable débris, including pine cones. The skeleton was in this layer, about 3 feet below the surface. Professor Valiant informed Mr. Rhoads that another skull was found, a good many years ago, in a swamp near Pemberton, and for a long time was used as a door-step before its real nature was discovered. Mr. Saltar, in the letter referred to above, stated that his understanding has been that this skull was found along the same stream and was used as a stepping-stone in crossing, until some progressive person sought to change its position. In the collection of the Academy, at Philadelphia, are 2 good teeth and parts of 2 others which are said to have been found at Pemberton. They are credited to G. C. Forsyth. At Princeton University is a nearly complete lower jaw, No. 8173, of a mastodon which was collected at Pemberton. Pemberton is on Rancocas River. In Salisbury and Knapp’s work of 1917, on page 184, it is stated that sands which seem to belong to the Cape May are found along the North branch of the Rancocas near Pemberton. 6. _Trenton, Mercer County._—Mr. S. N. Rhoads, in 1903 (Mamm. Penn. N. J., p. 235) stated that there is in Rutgers College Museum a specimen of tusk of mastodon which was reported to have been found in 1878 associated with stone implements in the Trenton gravels, 12 feet below the surface. Cook (Rep. Stat. Geol. New Jersey, for 1878, p. 15) stated that the tusk was found at a depth of 14 feet, with the gravel and stones partly stratified over it. There may be a question whether the tusk belonged to a mastodon or to an elephant. Professor S. Lockwood (Pop. Sci. Monthly, vol. XXLI, p. 344) wrote that he had seen a tusk, doubtless the one mentioned above, taken from the Trenton gravels. Whether or not this tusk was found immediately at Trenton was not stated, but Cook reported that it was found at Trenton.
