Methods of stream measurement ( ^\',tll r Suj,/,/;/ mul Jrrl</. I'aprrK, V. S. (Irol. 

 Surrey, Nil. '>(!, pp. 61, j>Is. lC^,ji<js. .;».— This niaterial has l>een compiled from vari- 

 ous reports and letters of instruction, and is intendeil ti> emluidy not only a descrip- 

 tion of the operations, but in some cases nnnute directions which may assist the 

 hydrographers and serve to increase the accuracy of results. It is designed not only 

 to assist and guide the hydrographers employed by the Survey or working in coop- 

 eration with it, but also to exhibit as nearly as possible the degree of accuracy of 

 the operations and of the computations of results.

Storage of water on Kings River, California, J. B. Lii'pincott ( Water Supply 

 and Irrig. Papers, U. S. Geol. Surrey, Xo. 58, pp. 101, ph. .U, figs. 2). — This is a rejiort 

 of investigations in which "the drainage basin of Kings River has been explored and 

 preliminary surveys and estimates prepared suflScient to justify the statements that 

 works can or can not be economically constructed at certain localities. . . . The 

 situation on Kings River is to a certain extent typical of that along a nund)er of 

 important streams of the AVest, and as a result of this investigation it is believed that 

 the reclamable area can be greatly extended by the construction of storage works 

 and also of power plants liy means of which, thi'ough electrical transmission, jtumps 

 can be operated at small expense out on the l>road valleys."

The silt problem in connection with irrigation storage reservoirs, J. C. 

 Nacle ( Tm/*.'?. Texas Acad. Sn., i{1901), Xo. S, }>p. SS-40). — A brief discussion of 

 this subject based on results of investigations carried out under the supervision of 

 E. Mead, in charge of irrigation investigations of this Department, and reported in 

 detail el-sewhere (E. S. R., 13, p. 999). 



Brack land in relation to irrigation and drainage {Ayr. ./our. ('ape dood 

 Hojie, 20 { wo::!), Xit. 7, pp. 307-405). — This is a discussion of the nature and reclama- 

 tion of alkali lands found in certain parts of South Africa. In the opinion of the 

 author"the only and radical curefor brack land, and preventive of slow accunuilation 

 of alkali ])y irrigation, is an adequate system of underdraining."
