bed of several feet in thickaess was passed through. In this 

 gravel deposit well preserved bones were found. They were 

 crushed into fragments by the drill, but a number of pieces, 

 from one inch up to three inches long, were brought up in the 

 wash. I saw these fragments about a week after they were 

 discovered, and they had the appearance of having belonged to 

 a living animal not longer ago than that time. Mr. Jennings, of 

 New London, Iowa, who had charge of the drilling, told me 

 that the bones had quite a fetid odor when first brought up. 

 It was difficult to determine from what particular bones the 

 fragments were, but I would place them as parts of the leg 

 bones of some animal of slender build. Below the gravel bed 

 the drill passed through a black deposit, which the well drillers 

 call "sea mud," and which rests directly upon the blue shale 

 of the Kinderhook, 231 feet below the surface. 



A quarter of a mile north of the Aspelmeier well the rock 

 bed is reached at a depth of less than thirty feet. It is the 

 hard, compact limestone of the Upper Barlington. This shows 

 a drop of over 200 feet in within a distance of 80 rods. 



Half a mile south of the Aspelmeier well, on the farm of 

 Fred Timmerman, there is another deep well which reaches a 

 depth of 184 feet without striking rock. The bottom of the well 

 is in a gravel deposit, which partakes of the nature of a forest 

 bed. From it much woody matter was brought up. 



A half mile still further south, making a mile south from 

 the Aspelmeier well there is still another deep well. It is on 

 the place of H. C. Timmerman. It reaches a depth of 188 feet 

 without striking rock. It likewise terminates in a gravel bed 

 containing much woody matter. In the two Timmerman wells 

 the water rises seventy- five feet. When last heard from the 

 Aspelmeier well was not furnishing a satisfactory supply. 



These wells indicate an old channel of great depth, and of 

 not less than a mile and a quarter in width. The width is 

 probably much greater. Mr. Frank Leverett suggests that 

 this ancient river bed was the water outlet of part of the ter- 

 ritory now drained by the Skunk river.
