made a careful exploration of a tract which we had previously been obliged to neglect, devoting a week to its study. The results of this examination are embodied in the main report.
Again I must acknowledge the welcome interest taken by the citizens of my district in our work, and the constant aid and encouragement rendered by hundreds whose names it is impossible to give. There has not been one instance of anything but courteous and generous treatment by all whom we have encountered in several thousand miles of travel through the region.
Allow me to assure you, personally, of my appreciation of all that you have done to render light the burdens of a comprehensive Survey. No small share of what has been accomplished is due to your unwavering support and indulgent treatment in both the field and office.
Very respectfully,
THEO. B. COMSTOCK,
Geologist for Central Texas.
REPORT OF MR. W. F. CUMMINS.
AUSTIN, TEXAS,

Hon. E. T. Dumble, State Geologist, Austin, Texas:
DEAR SIR—In compliance with your request I herewith hand you a report of the field work done by myself and assistants since January 1, 1890. Previous reports have embraced the work done up to that date. When the previous report was written we were encamped at Dockum, in Dickens County, at the foot of the Staked Plains.
The weather turned very cold, my men got sick with "la grippe," and it being impossible to get feed for the stock for some distance after leaving this locality, I abandoned the project of making another complete section across the Permian formation from this place, as I had intended.
I made such observations in that vicinity as was possible without moving camp, going in one instance up Blanco Canyon as far as the south line of Floyd County.
After supplying ourselves with provisions and feed for the stock we began our return trip, going northeastward, crossing the head of the north fork of of Croton Creek, to the head of the south fork of the Big Wichita River We traveled down the north side of that stream to the old McKenzie trail. Crossing the river at that place, we kept down the south side of the river to Benjamin, the county seat of Knox County. This is the first place at which we
