40 RIO GRANDE COAL FIELDS OF TEXAS. [bull. 164. • 
On the hilltops to the southeast of the Guajolote ranch clays occur 
above the micaceous sandstones. Ten miles, by road, southeast of 
this ranch, the following section was observed:

Feet. 
2. Shaly sandstone, fine grained, laminated, ripple marked in the upper part, and 
containing obscure or poorly-preserved leaf impressions 20 
1. Thinly laminated sandy clay shale 15 
From No. 2 several specimens of leaf impressions were obtained and 
submitted to Professor Knowlton for determination. He makes the 
following notes on them: 
There is one fine leaf in this lot, but it unfortunately appears to be new. It is a 
fine, narrow, toothed Celastrus. There is also a small fragment of a palm leaf, but it 
lacks both apex and point of attachment, and is thus deprived of all characters. 
There are two or three other fragments of leaves and a large number of stems, possi- 
bly of monocotyledons. 
The new species of Celastrus appears to resemble most closely a species (C. recti- 
nervis Ward) from the Fort Union (Eocene) of Montana. The palm has some resem- 
blance to a Denver species, but as it lacks the essential characters it is impossible to 
identify it. 
One and an eighth mile from the foregoing locality the first outcrop 
of the Eocene lignite was seen. The rocks in the vicinity consist of 
micaceous sandstones and clay shales. The dip is about 1° south of 
east. 
From the last-mentioned locality to Santo Tomas the lithologic char- 
acters of the rocks are about the same, i. e., they consist of interbedded 
micaceous sandstones, which vary much in hardness and in color. aad 
of clays or clay shales. 
About 8 miles before reaching Palaf ox poor remains of marine fossils 
were collected in a micaceous sandstone. 
Section of butte 4 miles north of Palaf ox. 
4. Gravel capping (Uvalde formation) . Feet. 
3. Red or brown sandstone 45 
2. Flaggy sandstone 3 
1. Crumbling shales 27 
Two and a half miles northeast of Palafox there is an exposure of 
lignite. 
The following are records of two prospect drills kindly furnished 
by Mr. D. D. Davis, superintendent of the Cannel Coal Company, 
which has its mines near Santo Tomas.
