probaly, as yet, unexcelled. The field work for the TuUy quadrangle 
and others in central and western New York has been done or 
directed by Mr. Luther. This work merits the praise which it has 
received from the state geologist who says that Mr. Luther's "skill 
in the careful stratigraphic determination of the older rocks in New 
York is in my judgment not to be surpassed." C. s. .

The third biennial report of the territorial geologist of Okla- 
homa contains five papers concerning Oklahoma geology: Prelim- 
inary report on the contact of the Permian and Pennsylvanian in 
Oklahoma, by C. T. Kirk; Geology of the Wichita mountains of 
Oklahoma, by C. N. Gould; Present status of the mining industries 
of Oklahoma, by E. G. Woodruff; Report of mineral deposits in the 
Wichita mountains (a list of localities from which samples have 
been collected), by Edwin I>eBarr; A preliminary report on the 
building stone of Oklahoma, by Eck Frank Schramm. 
Mr Kirk's paper, though a "preliminary" one, is of more than 
passing importance to stratigraphic geologists. Here we have 
a description of the passing of the lowest Permian limestone, the 
Wreford limestone, or its equivalent, nearly across Oklahoma. 
Gould has noted the southern ending of the Marion and Wellington 
formations in northern Oklahoma where the limestones seem to 
disappear and merge into "Red-beds."* Kirk describes the Wre- 
ford limestone of Kansas as being replaced by two coalescing layers 
of sandstone, which he calls the Payne, and traces the sandstone as 
far south as Norman, Oklahoma. 
On jage 9 in his paper occurs a section in which the sandstone 
representing the Pawhuska limestone of Adams, (correlation prob- 
ably taken from Bulletin 211 of the U. S. Survey) and the Payne 
sandstone occur in a 29 foot section of sandstones. In Kansas these 
formations are separated by about 700 feet of limestone and shales. 
Of this amount nearly lOO feet, including the limiting layers, is of 
limestone. Here in the Cimarron valley this section is represented 
by three layers of sandstone, two, six and eight feet thick respec- 
tively, and one of fifteen feet. These figures when taken in con- 
nection with Adams' statements, published in various places, that 
there is no unconformity gives a peculiar result. While this is 
not at all impossible when the geology of the surrounding region 
is considered, yet it opens up some very important points both 
paleontologic and stratigraphic. particularly so, when it is remem- 
bered that these sandstones are supposed to be typical "Red-beds" 
and are an "encroachment to the eastward of the line of red color- 
ation" without unconformity. However, Kirk suggests that "When.
