WINFIELD’S DEEP WELL 
111 
The first three feet measured the depth of loam or black soil. 
3 to 80 feet ; — 77 feet of clay which took the well down to 80 
feet where rock was first found. 
80 to 190 feet ; — this space was occupied by hard lime rock ; there 
were many horizontal layers or seams in this lime rock. 
190 to 510 feet; — this space was occupied by 320 feet of shale; 
shale is a soft slate rock like soapstone. 
510 to 618 feet; — this space of 108 feet was occupied by lime 
rock; this rock was more of a solid layer than the upper 
stratum of lime rock before-mentioned, and a little lighter 
in color. 
618 to 808 feet; — this space of 190 feet was occupied by shale; 
this shale was more in streaks of color, running from green 
to brown ; all shales found in this well were disposed to be 
sticky. In other regions where the McCarthy Well Company 
had worked, mostly north of this, the shales were less inclined 
to be sticky. 
808 to 818 feet ; — this was more of a hard $late than anything else. 
818 to 828 feet ; — a dark brown shale. 
828 to 1114 feet ; — this space was occupied by a lime rock of 286 
feet in thickness; this lime rock was brownish in color at 
times; at one time in this rock, some shells were drilled up, 
pieces big enough that they were recognized as shells re- 
sembling clam shells. 
1114 to 1128 feet ; — a white sand rock, very hard and fine-grained. 
1128 to 1143 feet; — a greenish colored shale, which drilled the 
same as the other shales. 
1143 to 1180 feet; — -this was another sandrock, 37 feet in thick- 
ness, white in color, coarser grained than the above mentioned 
white sand, and water-bearing. This was the St. Peter sand- 
stone, which is always white and coarse, one of the water- 
bearing strata of the earth in this region, and considered by 
drillers as the source of a never-failing supply of water. 
1180 to 1268 feet; — this was a lime rock which was penetrated 
to a depth of 88 feet. Here the drilling ceased. The depth 
of the well is 1268 feet. This rock has very hard layers al- 
ternating with softer layers. There were quite a number of 
these layers. There seemed to be more water in this rock 
than in any other encountered in the drilling of this well. 
The drilling of the well ceased on April 23. The test of the 
supply of water was begun on Friday, April 29, by pumping at
