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-

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

 bones were badly decayed, and most of them were broken up and

 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.
