formed the control of the middle branch of the jMalaekahana 

 stream, near Kahukii. All of the equipment lost and damage 

 done has been replaced and repaired at a low cost. 



Lihue rain gages registered nearly 15 inches for the 24 hours 

 ending September 27, a. m. On September 22 the Waihee rain 

 gage registered 10.7 inches and the Hana rain gage registered 

 12.8 inches. The total rainfall for the month at Keanae was 

 about 45.0 inches. 



FLOOD MEASUREMENTS. 



The September floods enabled the engineers on the islands of 

 Kauai, Oahu and Maui to secure much needed flood measure- 

 ments, on many streams ; and the data obtained are of great value 

 in determining the maximum run-off of streams. As a rule 

 floods in Hawaiian streams run off so rapidly that it is rare that 

 an engineer can reach the station in time to secure measure- 

 ments. The September floods were sustained sufliciently long 

 to enable men to get to the stations before these subsided. 



The cooperative stations constructed by the Kahuku and Laie 

 p'lantations were established primarily to register the flood run-off 

 of the streams in that vicinity. This information is desired to 

 determine whether or not the construction of a billion-gallon 

 storage project in that vicinity would be justified. 



O.VnU AND -VDMINISTRATION. 



During September four papers relative to hydrographic and 

 conservation subjects were prepared. 



One two-thousand-wood memorandum was prepared for the 

 Chamber of Commerce, which covered the general scope of the 

 work, the work already accomplished, the work now in hand, 

 and the results to be worked for. 



A two-thousand-word article relative to the hydrographic work 

 was prepared and mailed for publication in the 1915 Hawaiian 

 Annual, at the request of Mr. Thos. G. Thrum. 



A three-thousand-word article on Conservation was prepared 

 and 50 lantern slides were made from photographs pertaining to 

 this work were purchased. This article is to be read and the 

 views shown to a gathering of Kauai people under the auspices 

 of the Mokihana Club at Lihue, on October 16 or 17. 



A three-thousand-word article relative to Hawaiian hydro- 

 graphic and conservation conditions was written. This article 

 will be presented at a conference of government engineers at 

 Washington, D. C, in December, 1914. 



A large amount of stream measurement work was accom- 

 plished. Fifty-two stream and ditch measurements were made 

 and three rain gages were visited. Six staff gages were re-
