50 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 



Luzerne Co. — The first and third lower molars of a bison mounted together 

 on a card are in the collection of the Acad. Nat. Sci., Phila. These are 

 labeled by Dr. J. Leidy as coming " With the fossil teeth [of horse, musk ox^ 

 etc.] from [Pittston] Luzerne Co., but apparently more recent Bison ameri- 

 canus.'" I have compared these with teeth of recent bison and find them 

 specifically identical. — See Rhoads, Proc. Acad. N. Sci., Phila., 1895, pp. 

 245, 246. 



MeKean Co. — See above, under Elk Co. 



Mercer Co. — A bison horn was found in this Co. in i 795, according to B. 

 S. Stokley in Memoirs Histor. Soc. Penna., vol. 4, p. 77. This indicates that 

 the bison had been exterminated in its former haunts in northwestern Pa^ 

 long before the last one was killed in Union Co. in the central part of the 

 state. Undoubtedly the last isolated remnants of this species lingered many 

 years in the fastnesses of the Allegheny wilderness, cut off completely from 

 the haunts of their western ancestors by the early colonizing of the Ohio Val- 

 ley. — Rhoads. See also under Crawford and Erie Cos. 



Monroe Co. — A fragment of the mandible of a bison about four inches long,, 

 containing the alveoli of two missing molars and the last lower molar intact, 

 was found in Hartman's Cave near Stroudsburg, about 3 miles from the 

 famous G^p of the Delaware River. Leidy figured this in the Report of the 

 Pa. Geolog. Survey for 1887, identifying it as belonging to the "bison, B, 

 americanus " [= B. bison']. "The crown of the tooth has apparently been 

 charred and crumbled by fire in the same manner as other bones from this, 

 cave which surrounded and lay within the site of an ancient fire place in the 

 superficial layers of the cave floor." The ramus itself " is unburnt and is 

 apparently of the same recent (unfossilized) age as the remains of the fox, 

 wolf and deer associated therewith. I have no hesitation in considering 

 Leidy's identification correct, and from the character of the ethnological re- 

 mains found in the same cave and the appearance of the bone itself, would 

 judge it had formed part of the feast of a Delaware Indian [or some wild 

 beast] in comparatively recent times." — See Rhoads, Proc. Acad. N. Sci.,. 

 Phila., 189s, p. 246. 



Ferry Co. — The following place names indicate the most authentic south- 

 ern range of the buffalo on the Susquehanna (see antea under Cumberland 

 Co.). They are all located in the eastern part of the Co., near the junction, 

 of the Juniata River with the Susquehanna. Owing to their number and the 

 topographical features of their location it is obvious that buffaloes were a 

 characteristic feature of this spot, probably crossing the Susquehanna here by 

 way of Haldeman's Island into the mountains of Dauphin Co., on their 

 easterly migrations from the Ohio watershed. The names are Buffalo Town- 

 ship, B. Bridge, B. Creek and New Buffalo. — Rhoads. 



Somerset Co. — A B. Bridge on B. Creek is located in the south central part.
