1. _Mannington Township, Salem County._—In Rutgers College, New Brunswick, New Jersey, is a mounted mastodon said to have been found on the Hackett farm, Chestnut Hill, in Mannington. This township is northwest of the town of Salem. It is stated that about 75 per cent of the bones are present in the mounted skeleton; the missing parts are restored in plaster or some other material. Rhoads (Mamm, Penn. N. J., 1903, p. 235) was informed by Professor Valiant that this skeleton was excavated from a bed of gray marl, at a depth of from 6 to 8 feet below the surface. According to Lewis and Kümmel’s geological map of New Jersey, 1912, this region appears to be overlain by the Cape May formation (see also Salisbury and Knapp, vol. VIII, Final Rep. Geol. Surv. New Jersey, p. 194). 2. _Harrisonville, Gloucester County._—In 1869, Cope (Cook’s Geol. New Jersey, p. 740) stated that a mastodon had been found at this place, but no details were furnished. Harrisonville is on Oldman’s Creek, and along this are distributed, according to the map above cited, materials belonging to the Pensauken formation. Bridgeton, Pensauken, and Cape May deposits are, however, not far away (Salisbury and Knapp, op. cit., pp. 31, 96, 97, 194, 198). 3. _Mullica Hill, Gloucester County._—In Cook’s “Geology of New Jersey,” Cope reported also that mastodon remains had been found at Mullica Hill, on Raccoon Creek, but here again no details were given. Following the map cited, and Salisbury and Knapp, page 194, we find Cape May deposits at the town, but Pensauken is not far away, and it is not known exactly where the mastodon remains were met with. 4. _Woodbury, Gloucester County._—Mr. Samuel N. Rhoads (Mamm. Penn. N. J., 1903, p. 235) recorded the discovery of a mastodon near Woodbury. It was found on Mantua Creek and was in the possession of Dr. J. C. Curry, of Woodbury. Mantua Creek flows south of Woodbury, about 2.5 miles distant. On the map cited the region is indicated as being covered mostly by Pensauken materials, but there is some Cape May (Salisbury and Knapp, pp. 100, 191). The Cape May is on a lower level along the streams. From Dr. Curry the writer learns that the remains of this mastodon passed into the possession of Mr. Herbert Twells, of Woodbury, New Jersey. Neither of these gentlemen is able to furnish any further information.
