tion timber or fuel. Second, to provide shelter belts or wind 
breaks. Third, road side and ornamental planting. And fourth, 
to extend and supplement the native forest in sections where the 
forest cover is unquestionably of value as a means of controlling 
the run-off and making available for use a larger percentage of 
the precipitation either on the surface or as an underground 
supply. 
Let me speak of the last named case first. As a typical exam- 
ple I have in mind the Ewa Basin on this island. Practically all 
the water for the plantations about Pearl Harbor comes from 
streams draining the Koolau Mountains or from artesian wells 
supplied by underground water from the same source. The rain 
that falls on the Waianae Mountains is important as far as it goes, 
but it is and always must be only a fraction of what results from 
the precipitation on the Koolau Range. As it is now much of 
the rainfall on these mountains gets away as flood water and 
escapes the duty it might be made to perform, either by helping to 
fill the high level irrigation ditches or as underground water to 
assist in keeping up the water-table for a longer time in suc- 
ceeding periods of drought. There is a belt above the cane fields 
and other agricultural land in the Ewa Basin that it would pay 
to get back under forest for the good it would do in holding 
some of the water that now escapes. The planting up of this 
belt is a case where all three plantations could well get together 
and cooperate. Needless to say the Division of Forestry would 
be glad to assist in any way possible in this or any other similar 
tree planting project. 
I hope that in time the Division of Forestry may have at its 
command sufficient funds to begin tree planting again on Govern- 
ment land. But at present I believe more good can be accom- 
plished by expending what money is available in assisting private 
owners and in the way of plant introduction. 
During the past year systematic relations of seed exchange have 
been established with over one hundred botanic gardens and other 
similar institutions in various parts of the world. By this means 
there have been received at the Government Nursery the seed of 
numerous trees and shrubs new to the Territory, some of which 
ctre sure to prove of very considerable economic value. To facili- 
tate this work an experimental garden has been made in upper 
Makiki Valley where the plants started in the specially constructed 
germination houses at the nursery can be propagated for subse- 
quent distribution. As soon as practicable the new trees and 
shrubs will be sent out to localities on the other islands where 
from situation, elevation and aspect they may be expected to do 
well. In addition to the experimental garden at Makiki, it is 
hoped to establish regular sub-gardens on the other islands, which 
shall eventually become centers of distribution. One such station 
is about to be made at Kalaheo on Kauai where Mr. Walter D. 
McBryde has consented to cooperate with the Division of Forestry
