a salt lick beneath which is a yellowish clay mixed with gravel 

 and sand, belonging to the age of drift. The salt work was origi- 

 nally a swamp, for the bones lie on this drift.

A fine tooth of a mastodon was found in Gallatin county and 

 presented to the State Cabinet, but under what conditions it was 



found is not at present known.

Shawneetown. Teeth of a mastodon were found close to the 

 water's edge in front of Shawneetown. They were imbedded in a 

 shallow deposit of bluish clay resting upon yellow clay and gravel.

Morris. In 1868 mastodon remains were found at Turner's

 Morris, obtained and presented to the State Cabinet, a part of a 

 thigh-bone, a fragment of a lower jaw, three teeth, and a few of 

 the smaller bones. The locality is a part of the old river bottom, 

 and in the lack of personal observation, I am uncertain whether 

 to believe that the presence of the bones indicates that the animal 

 was mired and died there or to suppose that the carcass was de- 

 posited there by the river.
