WATER SOILS. 1059 



"The purpose of this report is to assemble in one publication the results of a series 

 of underflow tests made in the drainage basin of Los Angeles River in 1902 and 1903 

 by the United States Geological Survey. 



" The report briefly describes the conditions under which ground water usually 

 occurs, especially in arid regions, and the fluctuations in its water level due to rain- 

 fall and to sinking flood waters. 



"The method of testing used was invented by Prof. Charles S. Slichter, and is 

 fully described in 'The Motions of Underground Waters' [E. S. R., 14, p. 640]. 



"An attempt has been made to describe briefly the method of sinking test wells 

 and the machinery designed and used during this investigation. The various devices 

 used in testing and the arrangement of the instruments, the methods of testing 

 found most satisfactory, the results obtained at each of the testing stations, and the 

 amount of underflow supposed to pass the Huron street section, are fully described."
