“These deposits occur in the Toyah Basin’ (or its extension), referred to 
iby Prof. E. T. Hill in his report on the Artesian Waters of Texas. This 
basin is one of a series of lacustrine formations occupying valleys eroded 
in the plains or enclosed by mountain blocks, the underlying and enclos- 
ing formations being the Eed Beds and the lower strata of the Comanche 
series of the Texas geologists.

“At the three places visited by me the sulphur was found below bare, 
apparently wind-swept spots, its presence being usually indicated either 
by clusters of gypsum crystals in the soil, -or by an outcrop of the sulphur 
itself, sometimes tolerably ipure, sometimes cementing the surface pebbles 
into a conglomerate. When further exposed by pits the sulphur is seen 
to occur in nests and irregular veins filling small fissures or crevices in 
the soil, the sides of these fissures being often lined with well-developed 
sulphur crystals up to one-fourth of an inch in size. The whole of the 
earth, to the depth of ten feet or more at the three localities visited, 
appeared to be impregnated with sulphur, sometimes almost imperceptible 
to the eye, but oftener in minute crystals concentrated along irregular 
lines.”

“The section here described was made in Mexico and New Mexico near 
the Initial Monument of the Mexican Boundary Survey, about three miles 
west of the city. The lowest part of it is exposed in the cutting of the 
Southern Pacific railroad on the west bank of the Eio Grande, where it 
cuts the pass through the mountains. The sections extend from here to the 
top of the hill across the arroyo southeast of the Initial Monument of the 
Boundary Survey. Tlie rocks are greatly faulted, folded and disturbed by 
igneous intrusions, so to obtain the sequence and thickness of the beds it 
was necessary to establish horizons and measure between them where we 
could find them.” 
A detailed columnar section covering about 700 feet is given, together 
with lists of species obtained from the various beds. The paper closes 
with notes upon the fauna taken as a whole.
