FOSSIL MASTODON AND MAMMOTH REMAINS. 13 



bones of a mastodon were taken. Elephas also inhabited this 

 region, though apparently less abundant than the mastodon. 

 Few teeth found near the surface at 



Galena are all the remains of this animal I met in this region.

KANE COUNTY. 



Aurora. In 1870 tusks and several teeth of a mastodon were 

 obtained from the superficial deposits of this county near Aurora 

 when the excavation for the track of the Chicago, Burlington and 

 Quincy railroad were made. These remains are in the Museum of 

 Clark Seminary at that place.

Aurora. In 1853, while extending the Burlington railroad 

 south of Aurora, workmen found teeth and a tusk of a mastodon 

 in a swamp on the edge of Fox river, where the Burlington repair 

 shops at Aurora are located. The remains were presented to 

 Jennings Seminary by an official of the road, Benjamin Hackney. 



(Reported by Mrs. Susan H. Quereau, Aurora.) 



Batavia. In cutting a ditch to drain a marshy lake of some 

 two hundred acres, some leg-bones and vertebrae of mastodon 

 (along with Bison and other bones) were found in a sticky clay 

 about five feet below the surface. 



(Reported, after personal investigation, by E. S. Riggs, Assistant Curator 

 of Paleontology, Field/ Columbian Museum, Chicago.)
