MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 75 



the soil, leaving it, however, a valuable pasturage for cattle during most of the 

 year." J. Clement, in Proceedings of the Surveyors' Association of N. J., 

 1880, p. 405. An examination of the map shows that this tract lies in Ha*n- 

 monton township at the head of the Nescochaque (Sleepy Creek?) branch of 

 Mullica River, about midway between Hammonton and Atsion. It is named 

 the Great Swamp. Probably the canal referred to was merely to secure 

 access to the Machesautuxen regions rather than a source of water supply, 

 as the tributaries of the Nescochaque reached far beyond the Great Swamp 

 to Winslow and Cedarbrook and must have afforded abundance of water. 

 This is probably the region of the Hammonton beaver dams, mentioned above 

 by Coffin. Rhoads. 



Burlington Co. " Saw lately an old dam on Wading River. Another, close 

 by, is mentioned in an old deed to my grandfather, dated 1848. Other dams 

 can be found on Wading River and its branches." Price. See also under 

 " historical notes," beyond. 



Camden Co. Exterminated in Camden Co. before 1820, one of their latest 

 haunts in that Co. being Beaver Branch of Big Timber Creek. Chew. Some 

 of the beaver dams mentioned above by Clement as being built in the head- 

 waters of the Machchesautuxen must have extended the operations of beavers 

 into the southeastern end of Camden Co. Rhoads. 



Cape May Co. A well-defined beaver dam may yet be traced at head of 

 Sluice Creek, y mile from South Dennis Station, Atlantic City R. R. Hand. 

 The last one seen near Dennisville was about 75 years (1814?) ago, but they 

 remained near Tom's River (Ocean Co.) much later. Miss H. L. Townsend 

 -fide Lee. " It was found in Cape May Co. 25 years ago, occasionally." 

 Abbott, Geol. N. J., 1868, p. 757. 



Mercer Co. Dams in Crosswicks Creek yet traceable. "Was formerly 

 very abundant, especially along the Assanpink Creek. " Abbott in Geol. 

 N. J., 1868, p. 757, and in letter to Rhoads. 



Ocean Co. See above, under Cape May Co. Tuckerton mill dam was 

 originally built by beavers just at high tide limit of Tuckerton Creek. It 

 formed in the early history of that region the foundation for the first highway 

 across the creek. A comparatively recent washout in this dam exposed the 

 original beaver-gnawed material of its foundation. Rhoads, fide Pharo. 



Salem Co. An old dam, 5 miles from Mickleton, bearing the name of 

 Beaver Pond, is cut off from Raccoon Creek. The ancient site of the dam 

 breast, cutting off a swampy section from the creek, is yet traceable, being 

 held in place by the roots of many willows growing upon it. Rhoads, 1898. 



Sussex Co. An article published in " Forest and Stream," in August, 1900, 

 gave a detailed account of the existence of beavers in the wilds of Sussex Co 

 by Mr. J. von Lengerke. The locality was not stated. In answer to my 

 inquiries, under address and date of New York, February 24, 1902, 1 received 

 the following interesting letter regarding these N. J. beavers :
