EUCALYPTUS CULTURE IN HAWAII. 



The study of the eucalypts in the Hawaiian Islands, the 

 results of which are now presented, was made in cooperation 

 between the Forest Service of the United States Department 

 of Agriculture and the Territorial Board of Commissioners 

 of Agriculture and Forestry, at the request of the Superin- 

 tendent of Forestry. 



The field work extended over a period of four months (De- 

 cember 1909-March 1910), during which time practically all the 

 important groves of Eucalyptus on the Islands of Hawaii, Maui, 

 Oahu and Kauai were visited and examined. Complete measure- 

 ments were made on 500 felled trees for the purpose of con- 

 structing volume tables. Wherever the groves were old enough 

 sample plots were established, which should serve as a basis for 

 studying future growth. 



The object of this report is to bring together and correlate the 

 information obtained in regard to Eucalyptus on the various 

 islands, and to outline a system of forest management for planted 

 groves. Since most of the systematic tree planting on these 

 islands has been done only during the last decade, and few stands 

 are now more than five or six years old, not enough definite data 

 are available at present to forecast with any degree of certainty 

 the exact financial returns that may be expected, but the informa- 

 tion obtained indicates very clearly that a number of species of 

 the eucalypts can be grown at a good profit in many places on 

 the Hawaiian Islands. 



NEED OF LOCAL TIMBER SUPPLY. 



The Territory of Hawaii, with its extensive sugar plantations, 

 camps, flumes, tunnels, and irrigation ditches, uses large quan- 

 tities of timber and lumber. No complete statistics on this sub- 

 ject are available, but the following figures may be considered 

 as quite conservative. There were during the last three or four 

 years used annually in Hawaii over forty million board feet 

 of sawed lumber and timber, 75,000 cords of firewood, 20,000 to 

 25,000 railroad ties, 25,000,000 shingles and 40,000 to 50,000 

 fence posts. This annual consumption of wood represents a 

 value to the consumer of at least one and one-half million dol-
