hills, and it is in these hills, north and south of the road, and 
within a radius of a mile from the depot, that we find our 
section. We desire to call attention to the occurrence of 
Gryphcea dilatata var. tvcumcarti Marcou at this locality, 
where a stop-off' of one day is ample time to permit a fair 
study of the section from the Paluxv sands to the top of the 
Fort Worth limestone. 
A little less than a mile west of the station there is a 
small branch or creek running north, which crosses the rail- 
road and shortly afterward turns eastward and islost sight of 
amid the undulations of the hills. On the east bank of the 
creek, just by the side of the railway track, an excavation some 
sixteen feet in diameter has been made by the railroad com- 
pany in expectation of getting water, and this gives us a clear 
section of sixty feet, the details of which are reproduced in 
the rock materials forming the creek-banks and hill-slope- 
north and south id' the road. The dip of the beds here found 
is very slight toward the Davis mountains. From the creek 
to the beginning of the hill section there is a small fiat so 
covered with drift that the underlying beds cannot be deter- 
mined. In the hill section, although detritus-covered in 
places, many washes afford a (dear section of about three 
hundred and fifty feet. The following is the section made by 
ourselves at our last examination, the measurements being 
from harometer readings:

FEET. 
1. Interbedded limestones and calcareous clays 'Jo 
The surface of the limestone shows many fragments of fossils, 
but it is difficult to obtain specimens sufficiently well preserved 
for identification. Natica plaiiata Roexn., and Cerithium b<>s- 
quense Shum., are found, also a plicate oyster, an Exogyra, 
and an Epiaster of indeterminable species. 
2. Massive limestone, the beds attaining a thickness of three feet 
in places, interbedded with thin seams of clay 30 
In these layers of limestone are found great numbers oiE.vogyra 
plexa Cragin, while the lower portion of the beds, which are 
somewhat less compact, afford a number of fossils, among 
which are the following: Exogyra plexa Cragin, Gryphsea 
pitcheri Mort., Pecten texanus Roem., Natica sp. ind.
