Moisture Equivalent. — The moisture equivalents of the surface 

 horizon samples were determined by the Division of Soil Technology 

 (table 10, and figs. 9, 10). The different types gave quite distinct 

 averages, though there was considerable variation within the type. 

 The Diablo clay adobe varied from 37% to 57%, with an average of 

 47%. The Altamont clay loam varied from 22% to 37%, witli 28% 

 as an average. The San Joaquin sandy loam varied from 7% to 

 15%, with the average of 11%. The Hanford fine sandy loam varied 

 from 11%; to 25%, with 15% as the average. These figures show 

 that as a whole the moisture equivalents of the several types are 

 distinct, though there is the usual overlapping in some cases. The 

 samples of a given t} r pe are in mam' instances closely similar, though 

 not always or even usually so.
