out, and that here the gravel and saud are in veins rather than stratified 

 over extensive areas. This, however, may apply only to the eastern 

 side of the Vermilion. The well at the station at Odell was down one 

 hundred and thirty feet. Becord as follows :

At Dwight, on the N. E. qr. of sec. 12, T. 30, E. 6 E., a boring of 

 twenty-five feet was reported all drift, and the well was abandoned at 

 that depth from tools getting fast. Water at fifteen to twenty feet. 



A boring was reported in the S. W. qr. of sec. 21, T. 2SN., E. 9 E., 

 of one hundred and five feet in drift, but no statement whether this 

 reached the bottom of it. This is over the line two miles, in Ford 

 county. 



At Chenoa, at the railroad crossing, a well bored one hundred and 

 thirty feet struck water at ninety feet, and at one hundred and thirty 

 feet, both rising to within thirty feet of the surface, or so reported. 

 This is probably from gravel in drift. 



At Avoca and west of it water is found from six to eighteen feet from 

 the surface. East of this, thirty to forty feet, and not so reliable as 

 west of the Vermilion. 



Sand is found on sec. 27, T. 27 N., E. 6 E., between Fairbury and 

 Avoca, with three feet of soil above it, and also found on sec. 1, T. 27 

 N., E. 5 E., on the vrest side of the ridge half a mile west of the Ver- 

 milion — reported sixteen feet deep and resting on coarse gravel. Pon- 

 tiac is supplied with sand from this point. 



The country between Fairbury and Chatsworth is a succession of 

 ridges rising gradually towards Chatsworth, the highest point being 

 one or two miles west of Chatsworth, and this is probably one hundred 

 feet or more higher than the ridge at Fairbury. 



The upper limestone of the shafts at Fairbury is traced in the wells, 

 and along low ground outcrops in a north-westerly direction, showing 

 the drift at less depth. It appears on Indian creek, two miles south- 

 west of town, and also outcrops three and a half miles north-west of 

 town. This limestone underlies a low ridge which is observable running 

 in a north-westerly direction in the prairie. Two miles east of Fairbury 

 is a ridge higher than the one on the west. The railroad cuts through 

 it to a depth of five or six feet, showing a considerable amount of drift,
