a plaster cast. According to measurements taken by the 

 workmen shortly before the sand caved in, the tusk was nine 

 feet eight inches in length and eleven inches in diameter at 

 the base, tapering to a blunt point about one-half inch in 

 diameter; and the concentric layers that compose it vary in 

 thickness from one thirty-second of an inch along the axis 

 to one-half inch in the outer layer. 



It rested on the right or outer side, in a bed of sand, which 

 was covered by eight feet of loam. The base of the tusk pro- 

 jected about five inches above the sand into the overlying 

 loam, while the small or distal end was covered by thirty 

 inches of sand. As found, it rested in the sand about thirty 

 feet above the creek bank and about half way up the gently 

 sloping hill on the east side, a distance of about 100 yards 

 from the creek channel. 



The sand in the. pit where the tusk was found shows con- 

 siderable cross-bedding and contains many layers of carbo- 

 naceous material and coarser sand and fine gravel. It was 

 twenty feet deep on the east or upper border, and has been 

 made by hauling away the sand, which is of an excellent qual-
