466 Laworth—Stratigraphy of the Kansas Coal Measures. 
the general section gives it but 950; at Kansas City the known 
thickness from the hill tops is 1000 feet, and that given in the 
general section is but a little over 1100. At Fall River the 
known thickness from the valley is 1405 feet, and that given in 
the section but 1800. At Topeka a hundred and ten miles from 
the southeast limit the known thickness below the hill tops is 
1750 feet with the deep well not having reached the base of the 
Coal Measures. In the general section the thickness here is 
2050 feet. The writer has no doubt but that could a well be 
drilled in from the top of Buffalo Mound near the Kansas 
River or from the top of the Flint Hills in the southern part 
of the state, it would be found that the total thickness of the 
Coal Measures from the top of the Cottonwood formation 
would exceed 2500 feet.*
