LETTER OF TRANSMITTAL. 
Honolulu, Hawaii, September 29, 1913. 
Sik: I have the honor to submit herewith and recommend for 
publication as Bulletin No. 35 of the Hawaii Agricultural Experiment 
Station, a paper on the Absorption of Fertilizer Salts by Hawaiian 
Soils, by William McGeorge, assistant chemist. In order to be in 
position to recommend a rational program for the management of 
Hawaiian soils it has been found necessary to make a study of all 
the properties of these soils. In the present paper many interesting 
points are brought out upon the subject of the fixing power of these 
soils for different fertilizer salts. It appears that the concentration 
of a soil solution depends perhaps more upon the fixing power of the 
soils than upon the solubility of the salt. 
Respectfully, 
E. V. Wilcox, 
Special Agent in Charge.
