6o TJie American Geologist. Jaimaiw, isou 
nical terms as seems advisable, but these features do not de- 
tract from its value as-a scientific and precise resume of 
what is known of the coal in lower Michigan. There are re- 
prints of this report which are for distribution b)' the state

Prof. Edward Orton Jr. has been appointed state geol- 
ogist of Ohio to succeed his father, the late Dr. Edward Or- 
ton. Prof. Orton became connected with the state surve)- in 
1882 as an assistant engaged in the study of the Coal Meas- 
ures of eastern Ohio. He collected and prepared the mate- 
rial for the Ohio mineral and geological exhibit at the 
World's Fair at New Orleans. Later he began the study of 
the clays and cla}' industries of the state and prepared the 
thorough reports upon these subjects for volumes Vand VII 
of the Ohio geological reports. As secretary of the com- 
mission appointed by the National Brick Manufacturers' As- 
sociation in paving brick tests he has conducted a large num- 
ber of tests which have been described in the reports of this 
Association. In 1894 he was appointed director of the new 
department of clay-working and ceramics in the State Uni- 
versity which has developed into a prominent engineering 
course of that institution. 
Under his direction the work in the various lines of eco- 
nomic geolog}' which are open for investigation in Ohio will 
be continued and no doubt will add to the knowledge of the 
economic resources of the state.
