Fifteen stream measurements at regular stations and two miscel- 

 laneous measurements were made. A large amount of private 

 rainfall and ditch discharge measurements were collected for the 

 1915 biennial report. 



AUGUST PLANS. 



Kauai. In addition to regular routine work, new ditch meas- 

 urement stations will be established on the Kekaha and Waimea 

 ditches and materials will be hauled and preparations made for 

 the construction of three new stream-gaging stations on the three 

 main branches of the Waimea river above all intakes. 



Oahu and Maui. Only necessary routine work will be at- 

 tempted. All employees will be used as much ?.s possible on the 

 preparation of data for the biennial period ending June 30, 1915. 



Hazvaii. The Superintendent of Hydrography will spend the 

 greater part of the month at Waimea, Hawaii, assisting the At- 

 torney General's department in the Waiakoloa water case. 



Very respectfully, 



G. K. Larrison, 

 Superintendent of Hydrography. 



NEW LIGHT ON POTASH POSSIBILITIES. 



The London Public Ledger, quoting the New York Oil. Paint 

 and Drug Reporter, gives us, under the above heading, the fol- 

 lowing interesting information concerning America's efforts to 

 make herself independent of Germany's potash supplies, or to 

 need them as little as possible. 



The stirring course of muriate of potash, we are told, sales of 

 round quantities having lately been made at $200, with prospects 

 of further sharp advances, centers unusually keen interest in the 

 latest official report of developing a commercial production of 

 potash in California. Dr. Norton, who is conducting investiga- 

 tions into our potash possibilities for the Government, treats the 

 subject with a thoroughness of detail both from the technical and 

 jiractical viewpoints. His technical qualifications have been forti- 

 fied by a valuable practical training acquired during his consular 

 service in Germany. 



Dr. Norton speaks most hopefully of the saline deposits at 

 Searles Lake, in San Bernardino County, California, as a potash 

 source, and the company which has undertaken the most capable 

 utilization of the vast visible supply of raw material has ex- 

 pressed its hope of marketing potash salts within a few months. 

 The commercial possibilities of these saline deposits are strength- 

 ened by the fact that they contain borax, sodium sulphate and 

 carbonate and common salt, besides being rich in potash. 



Much attention is given to the utilization of the enormous
