town. This, at time of our last visit, in October, 1874,. was less strongly impregnated with sulphur than the large one in the southwest part of the town. It is said that these springs, which are more than one mile apart, alternate in strength-when one has strong sulphur water, the other is weaker, and vice versa. Large supplies of water are at both places, for bathing, etc., and bath-houses for both ladies and gentlemen are there. Lampasas, with its clear waters, both fresh and mineral, its beautiful shade trees, elms, liveoaks, etc., river, hills, and varied scenery, is a delightful place of resort.

OTHER SULPHUR SPRINGS

are in Hopkins, Grimes, Rusk and other counties, all of which have their visitors, but not having seen these springs. I can only allude to them.

GEOLOGY

-TERTIARY.

The lime between the oldest tertiary (eocene) and the middle tertiary (miocene), has not been clearly defined. Southward we know that Bastrop county belongs to the eocene, and also that a large portion of Washington county is probably miocene. In this county, no fossils of the eocene have been found, excepting in its northeastern portion. The rocks of Bastrop county are mostly sandstones, a large portion of which are highly charged with iron. Some of these, having little sand and much clay, make good ochres, and these are not uncommon in some of the hills west of the Colorado river, not far from the old residence of Judge Eastland. These ochres are in quantities enough to be of commercial value.

Robertson county, and the other tertiary counties north of it, belong to the eocene. The prevailing rocks are sandstones; many of them have a large per cent. of iron, often gradually passing into iron ores of good quality. A buff sandstone, containing a small per cent. of lime, extends from the northern part of Bastrop county through Burleson into the eastern part of Milam; is occasionally met in Robertson and also in Cherokee, passing eastward into Nacogdoches, and northward into Rusk county. It has a thickness of from four to about eight feet, varies in hardness, generally being rather soft and friable, abounds in fossil
