the American with the European classification by restricting the 
term Comanchean to the pre-Washita rocks. A more artificial 
systemic boundary could hardly be drawn. No one well ac¬ 
quainted with the Comanche fauna and with the field relations 
of the Comanche rocks could accept such a boundary between 
systems, or such a restriction of the title Comanche which is now 
applied to a perfectly natural provincial series. 
In southern Texas, on Devils River, and on the Rio Pecos, as 
has been stated by Dumble and other Texan geologists, and con¬ 
firmed by my own field observations, there is a complete lithologic 
transition from the Fredericksburg limestones to the Washita beds, 
and a recurrence of the Fredericksburg faunal facies high in the 
Washita rocks just beneath the Del Rio formation. I refer to 
the persistence of the Edwards limestone type of lithology in the 
equivalent of the Georgetown limestone, and the recurrence of the 
Edwards faunal facies, characterized by certain rudistid and 
nerinean types, above beds with characteristic Georgetown fossils. 
Making due allowance for differences in faunae due to littoral, 
deeper water, and reef facies, all of which are present in the Co¬ 
manche sequence, the entire Comanche fauna is a unit showing 
only such progressive changes as are to be expected within a series. 
From all these considerations, and from others which can not 
be detailed here, the conclusion is reached that the Comanche suc¬ 
cession, as defined by R. T. Hill, is a good provincial series; but 
in my opinion the term should be restricted to rocks in Texas and 
Mexico, and to those of adjacent regions that can be strictly cor¬ 
related with them. Its application as a series term to the Early 
Cretacic sediments of the Pacific Coast is not justified by the 
present state of knowledge, and the recognition of Comanchean 
as a system of world-wide application is still less justified.

Employment of Geologists. Some things are seen clearly; and 
some things I see not so clearly. Not being superstitious, spooky 
shadows and the like are not mistaken for ghosts, but rather are 
credited with being real things that are made shadowy by the 
foreground over, or through, which they are viewed. It seems 
now just as glorious to be a genuine geologist as it did thirty years 
ago in the anticipation. But, being it looks far less clearly and 
not so great a success. Not that the Bryan attack on Biologic
