MIKILUA ARBORETUM. 
On September 7, the Superintendent and myself, accompanied by the 
horticulturist, Mr. Griffin, selected a site at the mouth of Mikilua Valley 
in the Lualualei Forest Reserve for the establishment of a xerophytic 
arboretum. Experimental plantings will be made of drought-resistant 
trees from all parts of the world for the purpose of discovering species 
which can be used in the afforestation of thousands of acres of dry 
and barren leeward slopes within the forest reserves. This is the first 
dry-land arboretum in the Hawaiian Islands and should be productive of 
valuable results.

KALIHI WATERSHED. 
Two days were spent with the Superintendent and a member of the 
Survey Department in determining and flagging a new makai boundary 
across the several ridges and valleys which constitute the Kalihi water- 
shed. This is a necessary preliminary of our plan to place this valuable 
water-producing area under strict protection as a forest reserve. Fol- 
lowing the survey, fences will have to be built to exclude the cattle 
which have ranged at will in the region for many years and have 
decimated the native forest over the entire area. When the fences are 
completed reforestation on an extensive scale should be undertaken at 
once in order to restore the water conserving power' of the region as 
rapidly as possible. 
TRESPASS ON TANTALUS'. 
Vigorous action was made necessary during the month by continued 
violations of Rule II, the offenders being Spanish and Portuguese dairy- 
men who have been in the habit of cutting grass from the forest reserve 
areas along the Round Top-Tantalus Drive. On September 9, I brought 
down Manuel Ruis and party of helpers with a Denby truck belonging 
to a Waikiki dairy. This being their first offense, they were released 
with a reprimand after giving up the grass cut in trespass. On Sep- 
tember 13, I found 16 men and boys of the Kapahulu district with eight 
wagons along the Drive. The grass which they had cut was confiscated, 
and on the following morning, 7 men, seniors of the party, were given 
a suspended sentence of thirteen months. They were: Joe Salado, 
Antonio Himenes, John Cardina, Antonio Boneza, Julian Sanchez, David 
Teixeira, and Frank Marino. An eighth, N. Santiago of Monte 's Dairy, 
having retained counsel, had his case continued. On September 26, 
Ranger Ellis arrested two Japanese workmen of T. F. Farm, proprietor 
of the Aloha Dairy. These men, Ishigawa and Matsuichi, were booked 
at the police station and on the following morning were given a sus- 
pended sentence of thirteen months. 
CO-OPERATION AT THE UNIVERSITY. 
In pursuance of the agreement between the Division of Forestry 
and the President of the University of Hawaii, the condensed course 
in general forestry was begun at the University on September 13, with 
a class of fourteen men. Two lectures on Forest Planting and two field 
trips with the class constituted my part of this work for the opening 
month. The initiation of this course, which contemplates covering the
