THE HARVESTING OF RUBBER IN HAWAII. 
AN OUTLINE OF A CO-OPERATIVE EXPERIMENT. 
By Ralph S. Hosmer, Superintendent of Forestry. 
[Read at the second annual meeting of the Hawaiian Rubber 
Growers' Association, Honolulu, Hawaii, Nov. 18, 1908.] 
The object of this paper is briefly to describe the cooperative 
investigation recently undertaken by the Hawaii Experiment Sta- 
tion, the four rubber plantations at Nahiku, Maui, and the Divi- 
sion of Forestry of the Territorial Board of Agriculture and For- 
estry, to determine the best method of harvesting rubber in 
Hawaii. 
By way of preface it may be recalled that in the summer of 
1906 during an examination of the planted forest at Lihue, Kauai, 
made by Mr. C. S. Judd, then an agent of the Division of For- 
estry, there was brought to public attention the existence of two 
THE ORIGINAL CEARA RUBBER TREES PLANTED BY HUGH 
HOWELL, NAHIKU, MAUI. THE YIELD OF THESE TREES 
WAS SO HIGH THAT UPON THE FAITH THEREOF ALL 
THE RUBBER PLANTATIONS IN THE ISLANDS WERE 
PLANTED.
