During the last summer the Seward peninsula of x\laska 
was studied by a party under the leadership of D. C. Wither- 
spoon, assistant topographer ; with the party were F. H. Mof- 
fit, assistant geologist, and E. C. Hill, topographic field assist- 
ant. The season's work resulted in the completion of the pre- 
liminary topographic mapping of the entire area of Seward 
peninsula, while Mr. Moffit completed a geological reconnais- 
sance of the region and studied in more detail the creeks in 
which gold has been produced. 
The Deer Creek coal field of Arizona has had a prelim- 
inary examination made by M. R. Campbell. This field is in 
Pinal county and about eighty-five miles northeast of Tucson. 
The field is about ten by five miles in area as far as now known, 
and the coal, which is of Cretaceous age, is principally in two 
beds which run from 24 to 30 inches in thickness. From the 
incomplete examination thus far made the coal seems to be a 
bituminous coking coal with volatile matter running from zt^ to 
36 per cent, and a high ash percentage. This coal field may 
have economic importance because of its proximity to the great 
copper camps of Arizona. 
The Tishomingo (Indian Territory) folio (No. 98) of the 
Geologic Atlas of the United States has recently been issued. 
It was written by Joseph A. Tafif. In the area here reported 
on are about 437,000 acres of coal lands and over 7,000 acres 
of asphalt land, llie asphalt deposits are ])articularly described 
m this folio. 
The question of the pollution of the Androscoggin river, of 
Maine, by wood pulp is being investigated by Franklin C. 
Robinson. 
The Hayden Peak (Utah) topographic (|uadrangle has re- 
cently been pul)lishcd. This, together with the adjoining Coal- 
ville cjuadranglc. covers the western portion of the Uinta for-
