and thence southward along the upper or western San Saba road to the town of San Saba, where we reached the base of the formation in this part of the State. We then turned eastward along the strike, of the San Saba Sandstone to the head of Lynch Creek, in Lampasas County, and thence to the town of Lampasas, where the survey practically ended.

The outfit was sent to Austin, where the wagons and camping outfit are stored and the horses and mules properly cared for.

At this place I will briefly refer to a few facts which will be presented in greater detail in the body of the report herewith submitted.

In the brief time which I had for the examination of the beds in the vicinity of Dockum, and which in the First Annual Report, 1889, I called the Dockum Beds, I could not get enough material by which to definitely determine the horizon to which they belong, but am of the opinion that they are the same as the Shinarump beds of Hayden, a member of the Triassic formation in Arizona. The beds constituting the upper part of the Staked Plains are of a later date, and are without doubt Tertiary. In these I found only fragments of vertebrates, and not enough to definitely determine the horizon to which the beds belong. A more detailed examination of that part of the country is required to determine any of the stratigraphic relations.

I still see no cause for changing my opinion that all the strata from the Coal Measures to the Dockum beds belong to the Permian. I think this will be fully proven by the facts collected on this expedition, as will be shown in the body of the report. I have made as large a collection of fossils from the several beds as it was possible to make in the time at my disposal for such purposes.

The two complete sections made across the Carboniferous, one along the Brazos River and the other along Pecan Bayou, have enabled me to correlate the strata of the Carboniferous south of the Cretaceous belt that extends across the country just below the Texas and Pacific Railway with the beds in the northern part of the State.

The highest and lowest beds of the Carboniferous occur in the southern part of the field, while only the intermediate ones are found in the extreme northern part.

Both the workable beds of coal are in the northern division, while only No. 7 is found in the southern division.

The relation of the several beds will be shown in the body of the Report.

Mr. N. F. Drake has been in charge of the topographic work, and to his efficiency in that branch of the service, and in making observations of the stratigraphic relations of the different beds, I am indebted for the completeness of the sections published elsewhere in the Report.
