At many places the permanency of the flowing streams is not 
assured, but the development of storage capacity would render 
the power secure and in many cases would increase the estimate 
of the amount available. However, the broken character of the 
country where these powers are available and the limited amount 
of arable land and water available for this land makes the economic 
value of the development of these powers questionable. 
The production of fertilizers from atmospheric nitrogen by the 
use of electricity may render the water power extremely valuable 
at such places where the power cannot be used for pumping water 
for irrigating purposes.

HAWAIIAN SUGAR PLANTATION STATISTICS. 
Honolulu, Hawaii, Nov. 14th, 1908. 
The enclosed Crop Reports for the year ending September 30th, 
1908, show the number of tons of sugar produced on the sugar 
plantations in the Territory of Hawaii, by plantations and islands, 
and the names of the various agents and also the tons of sugar 
produced on each plantation for each of the ten years from Sep- 
tember 30th, 1899, to October I, 1908, inclusive. 
The average yield of sugar per ton for all of the plantations 
was in 1906, 8,945 lbs. per acre, or, in round numbers, 4^ tons ; 
the average of the irrigated plantations was 11,526 lbs., or sH 
tons; and the average of the unirrigated plantations was 6,140 
lbs., or a trifle over 3 tons per acre. 
The total area of the land in these islands is 4,127,360 acres. 
Of this about 200,000 acres are under cultivation in sugar, of 
which about 105,000 acres are irrigated and 95,000 acres are un- 
irrigated. 
On the irrigated plantations about 1,000,000 gallons of water 
is applied per day to each 100 acres of land. To December, 1906, 
the cost of the irrigation systems of the several plantations was 
$14,069,804.88. 
A little over $2,000,000 is expended each year for fertilizers. 
An average of about $4.65 for each ton of sugar produced, and 
$22.20 per acre for the crop. 
It must be borne in mind that from eighteen to thirty months 
is required to mature a crop of sugar cane, so that the number of 
acres cultivated for each crop does not represent the total area 
under cultivation. For the crop of 1906, 96,228.6 acres were cul- 
tivated, producing 430,368.2 tons. 
The plantation companies are nearly all incorporated, and the 
shares of stock are held by about 7,000 stockholders. 
Note: — As most of the readers of the Forester have already 
received copies of the printed tables issued by the Hawaiian Sugar 
Planters' Association, it is only necessary here to give the totals 
bv islands, as follows :
