About a mile northwest of Tyler, on the Canton and Tyler road, a small section shows:

Immediately west of Tyler the lowest deposits to be seen consist of thinly laminated red and white sand and clay overlaid by a yellow sand.

Within the limits of the town of Tyler the same characteristic sands and clays crop out at various places where the streets have been graded. At the corner of Beckham and East Erwin streets the section shown is:

On South Broadway, immediately below the opera house, the same stratified sand and clay lie upon a stratified brown sand, and are overlaid by stratified ferruginous sand and gravel. Going east from Tyler, on the Longview road, a cut close to the eastern limit of the corporation gives a section of:

Six hundred yards east, on the same road, the stratified sands and clays appear underlying the mottled sand. In this section the clay is predominant.

These red and white sands can also be seen at intervals along the the line of the International and Great Northern Railroad as far south as two miles north of Troupe.

3. SECTION FROM TYLER SOUTHWARD, ALONG THE LINE OF THE TYLER SOUTHEASTERN RAILWAY TO LUFKIN.

The general course of this section is from south to southeast through a portion of Smith, the whole of Cherokee, and a portion of the northern end of Angelina counties.

In the neighborhood of Tyler the red and white stratified sands appear dipping in two directions—those on the east of the town in an east and southeast direction, while those exposed on the west have a general northwest to west course. The tops of the hills are covered with a stratified brown sand containing thin seams of ferruginous matter.
