branches of the river at points at or near the forest reserve hne, 

 and above all homesteads. Measurements made after a dry 

 period of three weeks showed a discharge of about twelve mil- 

 lion gallons per 24 hours. 



KAUAI. 



The entire month was spent on general improvement and meas- 

 urement work. The defects of the 700-foot level windward 

 stream stations which were uncovered by the recent floods, were 

 rectified and a large amount of boulders and other materials with 

 which the floods had choked the measurement sections was re- 

 moved. Sixteen stream discharge measurements were made and 

 nine rainfall stations were visited. 



Conferences were held with the ^Manager of the Hawaiian 

 Sugar Co. and with the President of the Lihue Plantation Co., 

 and these officials agreed to maintain and operate all measure- 

 ment stations witliin their respective jurisdictions in the future 

 without cost to the sfovernment. 



OAHU. 



Forty stream measurements were made and two rain gaging 

 stations were visited. The greater part of the month was spent 

 by all employees in the Honolulu office in the preparation of data 

 and reports. The station maintained by the Waiahole Water 

 Co. above the north portal power house was discontinued as hav- 

 ing served its purpose. Four measurements made at the station 

 below the power house declared the fact that the tunnel dis- 

 charge has remained practically constant for the past three 

 months, at about S?> million gallons per day. 



KAUAI. 



Only routine operation work was done. All continuous water 

 stage register stations were visited, instruments were inspected, 

 and records secured. Two rainfall measurement stations were 

 visited and the rainfall measurement station at lao cave, eleva- 

 tion 1720 feet, was discontinued, as the records from this station 

 have been almost identical with those obtained in the lao table- 

 land, elevation 1500 feet. 



HAWAII. 



Mr. C. T. Railev, Acting Superintendent, spent December 3 

 to 7 on Hawaii, collecting data for the use of the Attorney-Gen- 

 eral to be used as evidence in the Hilo Boarding School ditch 

 case.
