1918] Stock: The Pleistocene Fauna of Hawver Cave 463 



The investigation of the mammalian remains has been made under 

 the supervision of Professor John C. Merriam, to whom the writer is 

 obligated for much counsel and advice. In comparing the Pleistocene 

 remains with Recent forms, the collections of mammals in the Cali- 

 fornia Museum of Vertebrate Zoology were freely drawn upon, and 

 the writer wishes to express thanks to Director Joseph Grinnell and 

 other members of the staff for many courtesies extended during the 

 progress of the work. 



During early stages of the research, the writer visited Hawver 

 Cave and explored the cavern under the guidance of the late Dr. 

 Hawver. While the work was in course of completion, a second 

 examination of the cave was made. During the last visit the writer 

 was very cordially received and much valuable aid was rendered him 

 by the Pacific Portland Cement Company. The limestone quarry 

 now being operated by this company is situated along the Middle 

 Fork of the American River not far from Hawver Cave. Grateful 

 acknowledgment for much kindness is given to M. J. Johnsson, super- 

 intendent of the quarry. 



All the text-figures of this paper have been prepared by Mrs.

HISTORY OF PREVIOUS INVESTIGATIONS 



Originally discovered in the early eighties when the region was 

 actively quarried for limestone, Hawver Cave was subsequently 

 brought to the attention of the University of California by the late 

 Dr. J. C. Hawver of Auburn, California. In 1907, E. L. Furlong 1 

 reported on a reconnaissance of the cave, naming the deposit in 

 recognition of Dr. Hawver 's energetic exploration of the cavern and 

 removal of the fossil remains. Furlong's studies were curtailed by 

 the rise of the water level in the cave, which prevented the removal 

 of much material. The preliminary report of Furlong includes, 

 therefore, only a provisional list of the mammals found. 



As a result of subsequent excavation by Dr. Hawver much addi- 

 tional material was removed. This is now in the palaeontological 

 collections of the University of California. In 1909, Professor John 

 C. Merriam 2 discussed briefly the occurrence of human remains in 

 Hawver Cave. Later N. C. Nelson, then connected with the Anthro-
