Plate A'll sliOAvs a comparison of the consumptive use of water by 

 Bermuda grass and salt grass, and also evaporation from the water 

 surface of a ground tank of the same size as the soil tanks. The ground 

 tank was No. 16 at the Santa Ana station. The water table in each 

 case was 2 feet in depth during the period indicated, and the results

given are the averages of three tanks of salt grass and of two tanks 

 of Bermuda grass. respectiA^ely. During the period of record the total 

 use of water by salt gra.ss was 29.6 acre-inches per acre, while that by 

 Bermuda grass was 34.7 acre-inches per acre. 



Although consumptive use by Bermuda grass is the greater, the 

 maximum 12-month record from ]May to April during the three years 

 of measurement was but little more than 3 acre-feet per acre in a year
