HAWORTH AND BENNETT.| General Stratigraphy. 71 
that no stratified rocks are exposed. Plate XI, figure 3, is a 
section from Saxton, Mo., five miles east of St. Joseph, to 
Hiawatha, in Brown county. It shows the Oread limestone 
on the surface at Saxton, the Burlingame limestone at Robin- 
son, and a mantle of glacial drift at Hiawatha and in between. 
Plate XII, figure 1, is a somewhat diagrammatic illustration 
of the Stanton-Allen limestone in a vertical section from Leav- 
enworth to Caney. In this figure the vertical scale is much 
greater relatively than in figure 2 of the same plate and is in- 
cluded to represent the varying thicknesses of these two lime- 
_stones at different places, and also the variation in thickness 
of the Vilas shales lying between them. With the single ex- 
ception of the Drum limestone, so thick at Independence and 
growing thin so rapidly to the north, no other limestones in 
the state vary in thickness nearly so much as the Stanton and 
Allen limestones do. A full description of this variation is 
included in a description of the Allen limestone. The varia- 
ble thickness of the Vilas shales lying above the Allen lime- 
stone is also well represented in this figure, a variation much 
greater than is commonly found in the shale-beds of eastern 
Kansas. Plate XII, figure 2, is a vertical geological section 
from Leavenworth to the south line of the state near Caney, 
covering the same distance shown in figure 1. It is drawn to 
a different scale, however, much more nearly the natural, and 
therefore the variations in thickness above alluded to could 
not well be represented. , 
Plate XIII is a vertical section northeast and southwest 
along the line of outcropping of the Burlingame limestone. It 
shows the Burlingame limestone as observable on the surface 
and the other limestones which outcrop to the east as they 
would appear in the section, provided they continued back 
westward in the same relative position and thickness shown 
along their respective outcropping lines. Of course we do not 
know to what extent they maintain these properties westward 
excepting as shown by various deep wells throughout the oil- 
and gas-fields. Many deep wells have been drilled, records of 
a goodly number of which are included in this volume. A care- 
ful study of these records reveals that the most, and probably 
all, of the limestone formations extend westward. Consider- 
able difficulty has been encountered in getting well records 
which are accurate in detail. It is common for drillers to run 
together in one group a number of various limestone and shale-
