ROCK ISLAND COUNTY. 



Milan. —A piece of a tusk was found in the excavation made 

 for brick clay by the Rockford Construction Company (1893?) on 

 the north side of Rock river and on the east side of the Milan 

 road south of Rock Island. It was taken from the red oxidized 

 layer which forms the top of the boulder clay in the base of the 

 bluff here and which was covered by a few feet of loess. The piece 

 of tusk was about two feet long, but crumbled and broke into 

 three pieces on exposure to the air. It was perceptibly curved, 

 and measured about six inches in diameter at the proximal end. 

 and about four inches at the distal end. The specimen is in the 

 museum of Augustana College, Rock Island. 



Rock Island. — In laj'ing the overflow pipe from basins of the 

 Rock Island water works on the bluff south of the city, a cut was 

 made in the loess to a depth of about twenty-two feet near the 

 edge of the bluff. In the lower part of this cut there was part of 

 a tooth of an elephant and also a piece of a bone of the leg. 

 The specimens were donated to the museum of Augustana College. 

 The loess, at the point in the bluff where the bones were found, is 

 about thirty- five feet thick, and the lower part of it is seen to be 

 somewhat peaty in some of the cuts in the streets to the west.
