During the winter of 1879-80, Mr. R. A. Blair, of Sedalia, Mo., has, through 
jhis industry and perseverance, his own personal labor and the expenditure of some 
money, become the possessor, in his own right, of a very fine collection of masto- 
don remains. ‘They were obtained from a spring at Mr. Wade Mosby’s, seven

bones were made. At that time Mr. R. A. Blair, becoming interested in the 
matter, began to work in earnest, and the result was the finding of the large col- 
lection now in his possession. 
The surface of the ground at the spring, where the bones were obtained, is 
about fifteen feet above the creek, which is about four hundred feet distant. The 
upper spring is about five feet higher than the other spring and ninety feet distant. 
‘They lie about two hundred feet from the base of the hill, just back which 
Tises up by gentle slopes. Mr. Blair dug a ditch from the spring toward the creek, 
passing through alluvial loam to a bed of gravel, which seems to lie nearly level 
and to pass beneath the spring, or six to eight feet from the surface, approaching 
the surface toward the creek. The gravel was not passed through. Blue clay 
“rested upon the gravel. The diameter of the spring and bog seemed to be about 
twenty feet. It may originally have been a little larger. The material within
