ganized under the Division of Forestry of the Board of Agri- 
culture and Forestry are:closely associated, and should, as Mr. 
Larrison states, be maintained in the closest possible form of 
cooperation. It is believed that such cooperation as will pro- 
duce the best practical results would be the creation of a Divi- 
sion of Hydrography under the Board of Agriculture and For- 
estry. This Division, if created, should consist of the present 
Hawaii District organization of the Water Resources Branch 
of the U. S. Geological Survey, in so far as the expenditure of 
the Territorial appropriation or allotment for this purpose is 
concerned. This organization is now indirectly reporting to 
the Department of Public Works. 
This arrangement would also eliminate the additional expense 
of maintaining separate offices, as is now being done by the 
Hydrographic Survey, and would keep the Divisions of Forestry 
and Hydrography directly in touch with each other, and under 
one administrative head. 
Additional reasons why the forestry and hydrographic oper- 
ations in the Territory should be maintained in the closest pos- 
sible cooperation are: 
(1) The data collected by the hydrographic survey show 
directly the effects of forestry operations. 
(2) In the routine field work of each service there is much 
work that will be duplicated by employees of both services, if 
it is not done in cooperation. The larger part of the time of 
field men of either service is consumed in traveling. A eonsid- 
erable portion of the field work done by the hydrographic service 
consists of stream and rain gage reading which requires that 
both classes of stations shall be visited at regular intervals. 
‘This duty does not require the services of an especially trained 
man, and a large part of this work could be done, and on the 
mainland is done, by forest rangers. On the other hand field 
men of the hydrographic service could, in the rounds of their 
duties, assist in exterminating wild cattle and goats, inspect 
fences, report depredations, fires, ete. It is believed that the 
cooperation of the two services would eliminate the cost of at 
least one field assistant or ranger in each island.
