officials relative to cooperative work, and as a result new equip- 

 ment will be established on a number of distribution weirs, the 

 records of which determine the amounts paid for water by several 

 plantations. 



Equipment for two continuous record measvu'ement stations on 

 the two main branches of the Kapaa River above all diversions, 

 and homesteads, has been ordered and these stations will furnish 

 run-ofT data of the Kapaa river which will be of great value to 

 homesteaders and to the Territory, in adjusting future nater 

 distribution. 



OAHU. 



The greater part of the month was spent on office work, in- 

 cluding the collection and working up of 1914 discharge, and 

 rainfall data. All measurement stations were visited, and twenty- 

 three measurements were made. 



A provisional estimate of the flood discharge of the Malaeka- 

 hana and Kahawainui streams for 1913 was prepared, and fur- 

 nished to the Kahuku Plantation Co. 



The channel at the measurement station established to measure 

 the water developed in the east end of the Waiahole tunnel had 

 become so changed by floods that it was no longer suitable for 

 its purpose. It was discontinued on January 1, and a new site 

 selected at a lower elevation. The Waiahole \\^ater Company 

 has agreed to pay the entire cost of establishing a clock register 

 station at the new site, and a Gurley register has been ordered 

 by cablegram for this station. The station w'ill probably be com- 

 pleted by April 1, 191.3. A series of measurements showed the 

 outflow from the tunnel on January 22 to be 32 million gallons 

 ])cr 24 hours. 



The special seepage and utilization investigation of W'aialua 

 plantation was started on January 2?. and will be com])lctcd in 

 February.

 tory in the Hilo Hoarding School ditch case. 



H. A. R. Austin, junior engineer, spent January 1 to 4th col- 

 lecting stream flow data relative to the VVaiakoloa stream near
