No. 60 (Zoology 9). Fishes of New York ; by Tarleton H. 

 Bean. 756 pp. The number of fishes included in this descrip- 

 tive catalogue is 3*75. Of these species 217 are marine, 141 fresh 

 water, and 17 anadromus. The small number of fresh-water 

 species is due to lack of extensive investigations in the water 

 bodies of the interior of the state. 



2. Geological Survey of Neio Jersey : H. B. Kttmmel, 

 State Geologist. Annual Report, 1902. 149 pp. 5 pis. — Under 

 the guidance of Dr. Kummel the New Jersey Survey is continu- 

 ing its excellent work, chiefly along the lines of economic geol- 

 ogy. The present volume contains reports on the Floods of 

 Feb. 28 to March 5, 1902, by C. C. Vermeule ; on Artesian Wells, 

 by Lewis Woolman ; on Forestry by F. R. Meier ; on the Min- 

 ing Industry, by Dr. Kiimmel and by Mr. Weed. Mr. Knapp is 

 at work on the coastal plain deposits. 



3. Geology and Petrography of the Crater lake National 

 Park ; by J. S. Diller and H. B. Patton. (Professional Paper 

 No. 3, U. S. Geol. Surv., Washington, 1902, 4°, 167 pp., 19 pis.)— 

 In the first portion of this work the geology is described by Mr. 

 Diller. He gives a complete and detailed description of this 

 remarkable body of water lying in a great crater in the top of 

 Mt. Mazama, of the mountain itself and of its geological history 

 and shows in various ways that the mountain was once a lofty 

 peak which, collapsing, left a huge caldera in its place. The latter, 

 filled with water, forms the present lake. 



In the second part Professor Patton gives the results of a 

 detailed and careful study of the igneous rocks of the mountain. 

 He shows them to consist of the andesites, dacites and basalts of 

 a number of different types, whose characters as shown by the 

 study of thin sections and by chemical analyses are fully pre- 

 sented. The work is illustrated by half-tones of many fine pho- 

 tographs and in addition to its scientific interest will without 

 doubt be of service as an authoritative handbook when this 

 interesting region becomes quite accessible to the traveling public.

4. Preliminary Report on a part of the Granites and Gneisses 

 of Georgia ; by Thos. L. Watson, Ph.D. (Geol. Surv. Georgia, 

 Bull. No. 9, 8°, 367 pp., 1902.)— This report is limited to a 

 study of the granitic rocks in those counties in which there is a 

 considerable technical production. In the first chapter the general 

 characters of granite are treated ; in the second, the properties of 

 rocks in respect to technical purposes are discussed. The author 

 then in the third chapter, after describing the general geology of 

 the area, takes up the occurrences of granite with especial refer- 

 ence to the individual quarries, and in the succeeding one dis- 

 cusses the general chemical and petrographic characteristics of the 

 Georgia granites. The volume concludes with a treatment of the 

 subject of rock weathering with especial reference to the areas 

 and rocks described. The volume shows a large amount of care- 

 ful work, both in the field and in the laboratory, the results of 70
