field work in the nature of rainfall observations, and the opera- 

 tion of a clock register steam gaging station on the Kiilae stream, 

 will be continued at least through the calendar year 1914. Fif- 

 teen monthly rain gages will be read, part by an employee of 

 the Bishop Estate, gratis ; and part by a gage reader employed 

 by this division. The records from these stations, combined with 

 those from stations maintained by private persons, should give 

 sufficient data to furnish a good approximation of the relative 

 precipitation over the entire Kona districts. 



All maps, data, etc., will be assembled as nearly as possible 

 during December, but the completed report and recommendations 

 will not be furnished until the rainfall and run-ofif records of 

 1914 have been studied and considered. 



From November 10 to 14 the undersigned, accompanied by 

 ]\Ir. T. F. Sedgwick, underground water expert, made an in- 

 spection trip over a part of North and South Kona. Mr. Sedg- 

 wick examined the underground possibilities of water and will 

 submit a report relative thereto. 



Hcai'y Precipitation. 



Heavy rainfall has been reported from all islands, and the 

 serious conditions of drought a few months past have been 

 changed to conditions of a superabundance of water which has 

 done considerable damage to fields, roads, bridges, etc. Records 

 received from high level rainfall stations as a rule show the 

 heaviest precipitation in the past two years. 



At the intake of the Wahiawa Water Company's ditch on the 

 headwaters of the north fork of the Kaukonahua stream 39.6 

 inches fell between November 1 and 25, while over 33 inches 

 were recorded during the month in the upper Nuuanu valley. 

 Extreme floods occurred all over Oahu on the night of Novem- 

 ber 20. On the south fork of the Kaukonahua stream the new 

 masonry diversion dam of the water supply system of Schofield 

 Barracks was destroyed by an extreme flood which, according 

 to the cooperative gaging station maintained by the U. S. Army 

 and this division, totaled more than one thousand cubic feet per 

 second. At Keanae, Maui, 43.5 inches of rain fell during the 

 month. On all islands the construction work was delayed by 

 floods. 



Kauai. 



Mr. W. \'. Hardy, field assistant, assisted by Mr. D. E. Horner, 

 field assistant, completed trails from the present power line trail 

 to the new Stevens clock register gaging station sites located 

 at an elevation of 700 feet on the Hanalei and Kalihiwai streams. 

 The materials for these stations were also ])acked into the station 

 sites on men's backs. This work was done under hard conditions 

 as both streams were in flood most of the time. Mve stream 

 measurements were made and tlu'ce rain gaging stations were
