tain slopes in this region. The results of my observations pro- 
hibited the formation of any such opinion. 
This rule, therefore, was not inspired by hastily formed con- 
clusions in an off-hand manner, but was recommended only after 
a careful study of the situation in the field, covering a period of 
years and was decided upon only after consultation with other 
foresters and after thoughtful deliberation of all circumstances 
justifying its promulgation, considering the greatest good for 
the greatest number of people. It was first' presented to the 
Board on April 19, 1920, again recommended in June of the same 
year and in my report for the biennial period ended December 
31, 1920, and was finally adopted at a Board meeting held on 
December 6, 1921. Copies of my letters of transmittal to the 
Board of April 9, 1920, and December 1, 1921, are herewith 
attached. 
Water Supply. 
Every drop of water originating on this area is needed and 
used, if not for city supply purposes, then for the raising of 
food' stuffs such as taro and rice, and it is the duty of the gov- 
ernment, as prescribed by the law quoted above, to maintain and 
increase the amount of this water. The water in Waiamao 
section of Palolo Valley is used for supplying residents in the 
eastern section of the city. The banana and vegetable growers 
in upper Manoa Valley depend upon the streams for their 
domestic water independent of the city mains. Apart from the 
above uses of this water for potable purposes, the surface streams 
supply water for irrigating the taro, rice and other cultivated 
crops in both Palolo and Manoa Valleys and on the plains be- 
low these valleys. 
The question of an adequate water supply for Honolulu is 
acute and is constantly before us. We read in our local journals 
almost daily articles on some phase of this question. If the 
water situation is serious now, what will it be a few decades 
hence when, if our aspirations mature, the city of Honolulu will 
have a much larger population and will need for its inhabitants 
every drop of water that falls on the mountain slopes of our 
city's watershed? We may neglect our obligation to the present 
generation, if we will, but it is our bounden duty to provide for 
future generations when the demands on the local water supply 
are going to increase rather than decrease. 
Forest Preservation Necessary. 
Unless steps for the improvement of the forest, such as that 
contemplated by this rule, are taken now, our fair city will suffer 
more acutely from periodic water-famine, eventually drought 
will be her permanent and chronic condition, and we will not be
