A driller's log of the well is given in Table I. ANDERSON COUNTY, KANSAS, AREA The area under consideration is located in Sec. 10, T. 23 S., R. 20 E., Anderson County, Kansas. The procedure was exactly the same as followed in the two foregoing cases. The following spreads were employed: .', .', .', and .'. The contour maps shown in Figure 8 for the four different spreads suggest the presence of an insulator at a depth of somewhat less than 500 feet. As the spread is increased, the effect of this disappears as shown
