In Three Parts. Washington, 1896. Part I. Director's Report and 
Other Papers. Pages xxii, 1076; with 67 plates, and 43 figures in the 
text' — Part II. Economic Geology and Hydrography. Pages xxv,

Resources of the United States, 1895: (first volume) Metallic Products 
and Coal, pages xxi, 542; (second volume) Nonmetallic Products, ex-

The report of the Director, in 200 pages, gives brief summaries of the 
work done by the several divisions of the survey, a detailed statement 
of the expenditures during the fiscal year, and a short biographical 
sketch of the late Prof. George H. Williams. In geological explora- 
tion and mapping, four parties worked in the New England region; 
seven in the Appalachian region; four in the Atlantic Coastal Plain 
region; four in the Interior or Mississippi region; six in the Rocky 
Mountain region; and seven in the Pacific region. Six parties conduct- 
ing field observations in paleontology are reported. In topographical 
mapping, work was prosecuted in twenty-four States and Territories. 
The entire area surveyed during the year was 48,066 square miles, of 
which about 44,000 square miles are designed for publication on the scale 
of 1:125,000, or about two miles to an inch, while the remainder is 
nearly all to be on the scale of i :62,5oo. The total appropriations for 
the survey during the fiscal year ending June 30, 1896, were $675,530.75; 
and the total expenditures $647,075.60.
