 continued during the coming summer.

 to the more cave-like appearance of the opening, as may be seen by 

 comparing figure 14 herein with figure 18 1 published in last year's 

 account of the work at Cumberland. 



The results of the work of the 1914 expedition have greatly 

 increased the possibility of accurate determinations of the fauna 

 represented in this very interesting cave deposit and it is hoped the

 greater importance.

 During the summer of 1914 Mr. Charles W. Gilmore, assistant
