of the Texas Geological Survey. The evidence from this source strong- 
ly corroborates the conclusion reached by a study of the vertebrates, 
showing the Permian age of the division. 
Part of the flora collected from the division was described by Dr. I. C. 
White, and the evidence thus obtained also corroborated the conclusion 
of the Permian age of the strata. 
The Permian age of this division being admitted, it follows that if the 
Albany division is but a different facies of the same beds it also must 
be Permian. 
This fact has been abundantly shown by the stratigraphic work done 
during the past season by myself and party. 
In previous years I made and published complete sections, by instru- 
mental measurement, across the area of the Albany and Wichita divi- 
sions at right angles with the strike, and gave descriptions of the differ- 
ent beds composing the divisions, with a partial list of the fossils col- 
lected from them. The lines of these sections were about seventy miles 
apart. The section across the Albany division began at Albany and run 
thence in a northwestern direction, crossing the Clear Fork of the Brazos 
river at the mouth of Fish creek. The section across the Wichita divi- 
sion began at a point eight miles north of the town of Seymour, and run 
thence to Wichita Falls. 
During the past year (1894) I have traced prominent beds found in 
each of these divisions across the country between these two sections, 
and have found them to be continuous from one to the other. By this 
means I was enabled to see the gradual change in the beds, and to un- 
derstand that they were the same in time of deposition. 
A map has been prepared to accompany the Fifth Annual Report that 
will show the lines of the sections previously made, and also the escarp- 
ments of the beds traced during the last year’s work, between these two 
lines of sections. 
The map will also show the type localities from which the specimens 
were taken as described by Dr. C. A. White. (Bull. FTo. 77, TJ. S. Geo. 
Sur.) It will also show the localities of the fossil flora described by 
White and Fontaine. 
The plan adopted for my work was to select some prominent bed in 
the Albany division and then trace it to the northeastward toward the 
section run across the Wichita division. By walking along the outcrop 
every foot of the way we were enabled to note the gradual change in the 
lithological character of the bed. We were also enabled to note the 
gradual extinction and change in the fossils as the beds changed in com- 
position. 
We found that a limestone in the Albany division with an abundant 
and characteristic Coal Measures fauna, gradually changed in composi-
