Review of Recent Geological Literature. &$ 
and the Museum publications, the author has included only the Trans- 
actions of the New York State Agricultural Society, and the Transac- 
tions of the Albany Institute. There is a special index to descriptions 
of genera and species of fossils prepared under the direction of John 
M. Clarke, occupying pages 527 to 653. N. H. \v. 
New York State Museum: 55th Annual Report of the Regents, 1901- 
Pages ri66, 991, with many plates. Published by the University of 
the state of New York, Albany, 1903. 
The report of the director of the State Museum and state geologist, 
Dr. Frederick J. H. Merrill, with numerous included papers by his as- 
sistants, fills 166 pages. It is accompanied with 36 plates, the first being 
a contour map of the state, on the scale of 12 miles to an inch, folded 
in an envelope pocket of the cover. Geological papers are contributed 
in this report by J. B. Woodworth, H. P. Cushing, H. L. Fairchild (as 
reviewed in the October Am. Geologist, p. 250), Arthur Hollick, Hein- 
rich Ries, and E. C. Eckel. 
In the latter part of this volume, important paleontologic papers, 
with admirable plates, are presented by the statu paleontologist, Dr. 
John M. Clarke, his assistant, Dr. Rudolf Ruedemann, and Elvira 
Wood. w. u. 
The Mineral Resources of the Mount Wrangell District, Alaska. By 
Walter C. Mendenhall and Frank C. Schrader. (U. S. Geol. 
Survey, Professional Paper No. 15, 71 pp., 10 pis., 1903.) 
In this paper the authors have presented the results of their own 
work in the summer of 1902, and have added to it from previous re- 
ports (chief of which are those by F. C. Schrader and A. C. Spencer, 
and by C. W, Hayes) so as to present an account of what is known t ■ 
date concerning the mineral resources of the district. This report is 
issued in advance of the contour map and a report on the general 
ogy of this region, but a hachured map accompanies the present report. 
The Mount Wrangel district extends from Valdez on the west to 
Mt. St. Elias in the east, and from the Pacific ocean on the south north- 
ward for about 250 miles. This district includes practically all the 
drainage basin of the Copper river, and towards the northeast includes 
considerable parts of the basins of the White and Tanana rivers, trib- 
utaries of the Yukon. 
The chief copper deposits of the district occur in the vicinity of the 
Chitina river which enters the Copper river from the east. Geological- 
ly this area is underlain by rock- of four different series, a- follows: 
(1) the Nikolai greenstone which is a more or less altered series of 
lava flows of presumably Carboniferoi (2) the Chilistmie 
limestone, Permian in age; (3) Triassic shales and limestones; 
(4) the Kennicott formation, consisting of conglomerates, sandstone*, 
limestones and shales of Jura Cretaceous time. The first three series 
are conformable and are considerably folded, while the fourth lies un- 
conformably upon the other-. Cutting all is a series of eruptives. The 
copper occurs near the junction of the greenstone and the Chitistone
