Geological Survey. New York: John Wiley and Sons. London, England: Chapman and Hall, Ltd. Cloth, 6x9^ inches; pp. 137; 24 illustrations in text. The book covered by this review con- tains seven chapters and seventeen tables. Each chapter contains a definite and logical portion of the whole subject matter, the titles of the successive chap- ters being as follows: Introduction, Conditions affecting stream flow. Instru- ments and equipment. Velocity-area sta- tions, Weir stations, and Discussion and use of data. The title of each chapter indicates clearly the substance thereof and plays an important part in the de- velopment of the whole subject. Chap- ters IV and VI, however, contain the most valuable and essential portions of the work. Chapter IV describes minute- ly the selection, establishment and oper- ation of a velocity-area gaging station, setting forth-clearly the theory and prac- tice of making stream measurements and methods of reducing field notes. Chapter VII handles the subject from the office point of view. In this chapter, the subject of the discharge rating curves and rating tables is gone into thorough- ly and scientifically, and the useful ap- plication of hydrographic data is briefly treated. The seventeen tables referred to are placed at the close of the book, and per- tain to the computation of river discharge and to the reduction of these data from one standard unit to another. Tables i, 2, 3, and 4 give the discharges in second- feet for the most common types of weirs. Tables 5, 6, 7, and 8 contain multipliers to be applied to the discharges given in table 4, based on Bazin's
