Report of the Genldcjiatl Surrey of Ohio, Vol. ]'//. lly Edwakd Orton, 
State Geologist. Roy. oct.. pp. xvi + 700: jilans and figures, .>() plates of 
fossils, and a case of ten maps showing the outcroij boundaries of the 
principal coal seams. The volume is divided into four main parts, vi/: 
Economic gt-ology. Arclieology, Botany and Paleontology. Tht're is 
also a general chapter by Prof. Orton. explaining the whole geological 
scale and structure )f the stale, and another by the same, on the 
clays of Ohio, their origin, composition and varieties. A very full 
chapter is on the clay-working industries of Ohio, by Edward Orton. .Ir. 
The coal fields are also described in a summary manner by the state ge- 
ologist. Gerard Fowke discusses in a very intelligent manner the arch- 
eology of Ohio. lie concludes the account of the mound-builders by 
the following statement: "Any statement, drawing or description of 
remains which attempts to show they were a race superior to, or differ- 
ent from all other natives of the United States, is not justified by any 
evidence so far discovered." The botanical cha[)ter is by Prof. W. A. 
Kellerman and Wm. C. Werner. This also gives the bibliography of 
the botanical literature of the state. Some contributions to the paleon- 
tology of Ohio are given by II. P. Whitfield, reprinted from the Annals 
of the New York Academy of Science. 1880. Prof. C. L. Herrick re- 
views the "Waverly group." Aug. F. Foerste describes fossils from the 
Clinton group. Fossil fishes are discussed by Prof. E. W. C'laypole, and 
Prof. A. A. Wright adds a supplement, the substance of both of which 
has appeared already in the American Geologist. Now Lower Siluri- 
an lamellibranchs are described by E. O. Ulrich, being an e.xtension and 
supplement to work on the same published by him for the Minnesota 
survey. The book contains a large amount of valuable material, aixl 
constitutes a worthy finale of the report of the Ohio survey. 
This volume completes the series begun witli the survey of Dr. .1. S. 
Newberry in 186!). It is perhaps to be regretted that the work is thus 
formally closed. Dr. Orion enumerates many imp(jrtant economic and 
scientific interests which yet need the attention of an oflicial geologist. 
The educational interestsof the state have a certain demand which they 
might make upon the legislaturi'. and llu- state university might ai)- 
proprialely continue the survey along certain lines. In .\labama and 
Louisiana, as well as in Minnesota and South Dakota, the state surve\ 
is a function of the geological department of (he state university. 
Dr. Orton's connection with the Ohio survey has been long ami often 
burdensome, and there is no doubt that lie feels great satisfaction and 
relief in seeing it finally and formally terminated. Hut few state gc()lo- 
gists hasc had the good foi'tuiie lo close (heir sur\'e,\s wiih such a com- 
pletion. N. U. W.
