* PAPERS ON THE GEOLOGY OF NEW MEXICO. 
By C. L. Herrick, 
President of the University ot New Mexico. 
The following- pages are derived from the results of studies 
carried on at intervals during four years. Several articles in the 
American Geologist have discussed certain features of the geol- 
ogy of the territory and may be considered to form a part of 
the present series. The enormous area over which these inves- 
tigations must extend before they can approach completeness 
and the interrupted course of the field work unite to prevent 
any symmetrical prosecution or publication of the work. It has 
seemed best therefore to print the results in sections covering 
definite areas more or less cursorily and to leave the task of 
correlating the data to a later period. These articles then do 
not presume a knowledge of the geology of the territory at 
large, as they ought to do in order to be complete, but are ma- 
terials toward a more synthetic study in the future. It is hoped 
that this method of publication will serve a good purpose in 
stimulating further work and in aiding in the practical develop- 
ment of the region.

THE GEOLOGY OF THE SOCORRO MOUNTAIN. 
With Plates IX, X and XL 
Probably nowhere in the territory can more suggestive 
geological data be found in so limited a space as in the small 
group of mountains lying immediately west of the town of So- 
corro and bearing that name. The mountain front at the north 
is prominent and precipitous, while the eastern face is elsewhere 
broken by intersecting canons and depressions. We here have 
in epitome the geological history of the entire region. The 
stratified rocks are represented by a few hundred feet of the 
lower portion of the Carboniferous limestones with the subja-
