A NEWLY-DISCOVERED CAVE DEPOSIT NEAR CUMBERLAND, 
MARYLAND 
In October, 1912, Mr. J. W. Gidley, assistant curator of fossil 
mammals, in the National Museum, made a preliminary examination 
of some cave deposits containing bones of Pleistocene age near 
Cumberland, Maryland, which had previously been discovered and 
reported by Mr. Raymond Armbruster, a citizen of Cumberland.

The results were very satisfactory considering the limited time avail- 
able, upwards of a hundred specimens being secured representing 
about 24 species of mammals, most of them either extinct or now 
living only in localities very remote from the mountains of Western 
Maryland. 
The fauna proves very interesting, and the “find” promises 
to be most important in that it will throw much additional light 
on our knowledge of the Pleistocene mammals of the eastern United 
States, or, in other words, those immediately preceding the existing
