202 The American Geologist. September. 1904 
returned to his home in San Diego. He is building up a large 
geological library for the west coast. 
Dr. I. C. White, state geologist of West Mrginia. has 
leave of absence for six months and has sailed to Brazil where 
be will examine and report on the coal fields of Rio Grande do 
Sul, the most southern state of Brazil. He left the United 
States July 5, and will return some time in December. 
Pr()]\ G. p. Grimslfa', of Topeka, Kansas, has been ap- 
pointed assistant geologist of West Virginia, and began work 
Aug. I, in the preparation of vol. iii, on clays, building stones, 
limestones, etc. 
The Ohio Geological Survey is carrying on both office 
and field work during the present summer. The following 
indicates the principal lines of work which the survey is at 
present conducting. Professor Edward Orton, Jr., State Ge- 
ologist, is completing his part of the work on cement and its 
uses and is also editing the manuscript for two other bulletins. 
It is his expectation that four bulletins will be published dur- 
ing the remainder of the year. Professor John A. Bow- 
nocker with an assistant is engaged in studying and mapping 
the distribution of the Pittsburg and Meigs Creek coals in the 
eastern part of the state. Professor Charles S. Prosser with 
an assistant is studying the stratigraphy of the Upper Silu- 
rian, Devonian and Carboniferous formations. Part of this 
work is directed toward the correlation of the Ohio formations 
with those of Pennsylvania and New York and a report is in 
preparation describing their stratigraphy in detail. 
The class in field geology of the Ohio State University 
during the spring term*of this year, under the guidance of pro- 
fessor Prosser, studied the various formations which are found 
in central Ohio. The Devonian limestones (the Columbus and 
Delaware formations), the Olentangy and Ohio shales of the 
Devonian ; the Ik-dford shale. Berea grit, Sunbury shale. Cuy- 
ahoga and Black Hand formations, Logan shales and Potts- 
ville formation of the Carboniferous comprise the formations 
which were studied the most thoroughly. The Saturdav field 
trips consumed the entire day. The rocks and fossils collected 
were later studied in the laboratory and a thesis prepared by 
each student which contained a description of the sections 
studied, together with a summary of the geological literature 
for central Ohio' relating to the above mentioned formations. 
The Dfa'Onian volume of the systematic reports of the 
Maryland Geological Survey is nearing completion. Tt will 
be a composite work consisting of three parts ; the Paleode- 
vonian by professor Schuchert, the Mcsodevonian by profes- 
sor Prosser and the Neodevonian by Dr. John M. Charlse.
