1-J" The American Geologist. Feb. i89a 
urination will be interesting, especially since he do longer con- 
siders this great series a southern deeper continuation of the 
Meek & Harden Series, as was his published opinion when the 
writer first had the pleasure of pointing out these rocks to him in 
1886. Prof. K. W. Cragin, who has been studying these rocks in 
southwest Kansas, where they occur in very different conditions 
from Texas, iii the last issue of this magazine, p. 2:!. has de- 
cided to drop the name Comanche series, and call them Neo- 
comian, after Marcou; so far have his studies progressed. The 
writer must confess that, from his own continuous studies of this 
great series he still feels undecided as to their actual synchronism, 
and considers the term. Comanche series, first proposed by him. 
still the most appropriate until more complete investigations are 
made. 
Cretaceous Tnliers. The great erosion to which the surface ol 
the southwest has been subjected reveals a number of inliers ol 
upper Cretaceous beds in the Eocene area of Arkansas and Texas. 
All of the Cretaceous outcrops of Arkansas are of this nature, 
being seen only where the post-Cretaceous beds of the Marine 
Eocene and Plateau Gravel (Quaternary) epochs have been (ait 
through by the drainage. Many of these inliers occur in the 
Eocene area of Texas, notably at the Friese place, in Bowie 
county, near Palestine in Anderson county, and at other places 
as have been described by Lawrence ('. Johnson in his report on 
the Tertiary Iron ores of east Texas. It is an interesting fact that 
all of these inliers are in the direct strike of the beds of the 
Grlauconitic division of the Upper Cretaceous, only the base of 
which, as at Corsicanaand Webberville, are exposed in the eastern 
edge of the main Cretaceous area, thus showing that the great 
beds of that division, which is the equivalent of the Ripley — 
rotten limestone — Tombigbee division in Alabama, are still mostly 
buried beneath the Koeene overlap in Texas. 
A New Sourct <</ Artesian water in Texas. In the American 
.Journal of Science for April. 1887, the writer published the pre- 
liminary announcement of the Fort AVorth-Waco artesian area, 
which is now known to extend from Denton to Pel Rio, a distance 
of 500 miles, and to be one of the most prolific artesian areas in 
the world, several hundred wells and numerous rivers which have 
their origin in fault-springs like those at Pel Rio and San Antonio.
