in behalf of the mining industry. A new branch of the Survey's 

 activity which has taken form during the past year is the classifi- 

 cation of Government coal lands, 22,700 square miles being 

 classified and valued. This work is a result of the movement for 

 conservation of National resources ; a movement which in turn 

 has been able to take intelligent form, as well as popularity, 

 largely as a result of the more purely scientific labors of the Sur- 

 vey since its organization. The work of the Survey is thus seen 

 to fall into two main divisions, work of a broad scope along 

 fundamental lines, whose great value and utility may only 

 become widely evident after the passage of decades, and work of 

 immediate utility to meet the demands of the people and of 

 Congress. The Survey is to be congratulated on having per- 

 sistently followed work of both divisions. 



During the year the geologic branch published 9 geologic 

 folios, 1 monograph, 2 professional papers, 18 bulletins and the 

 annual volume on Mineral Resources. Mention of the important 

 results cannot here be made. The topographic branch mapped 

 25,658 square miles, making the total area surveyed to date in 

 the United States 1,051,126 square miles, or about 35 per cent. 

 In Alaska 6,626 square miles were mapped, mostly on the scale 

 of 1 : 250,000. Important work by the water-resources branch 

 was done in the lines of stream-flow and ground-water investiga- 

 tions, and investigations regarding the quality and pollutions of 

 waters. 



The entire appropriation for the Survey was $1,445,020, of 

 which $300,000 was expended for topographic surveys and 

 $200,000 for geologic surveys. j. b. 



2. Geological /Survey of New Jersey : Henry B. Kummel, 

 State Geologist, Franklin Furnace Folio. — There has recently 

 been issued by the Geological Survey of New Jersey in cooperation 

 with the United States Geological Survey, a geologic folio of the 

 Franklin Furnace region in Sussex County. This locality is one 

 of the richest mineral regions in the world, alike important 

 economically for its enormous zinc deposits at Mine Hill and 

 Sterling Hill, and no less scientifically for the number and variety 

 of its mineral species. In addition to the zinc minerals, over 

 ninety well defined species are known from this locality, and 

 eleven of these have not been found elsewhere. The region 

 contains also extremely valuable deposits of white crystalline 

 limestone and magnetic iron-ores. 



In the descriptive text of this folio, the geography, geology and 

 geologic history of this region are fully described. Complete 

 information is given regarding the mineral deposits, and maps 

 and cross sections show the location and shape of the valuable 

 ore bodies. The folio may be obtained from the State Geologist, 

 Trenton, N. J., price 25 cents, postage 15 cents additional.
