HAWAIIAN ISLANDS 



been spent in the "improvement" of home grounds, and 

 some architectural gardening is to be found, but natu- 

 ralistic landscape gardening is, as yet, in its infancy in 

 the islands, though nature furnishes so many excellent 

 types. 



Possibilities of Horticulture.— There can be no 

 doubt that the climates and the qualities of the soils 

 are such as to give to this country a very brilliant fu- 

 ture in the production of varied and superior horticul- 

 tural products. The amount of available land, however, 

 is limited, since the lariier tillable tracts are already 

 used in the production of sugar-cane, and will probably 

 remain so occupied. Still there are a good many small 

 areas admirably adapted to horticulture. 



Then, too, the matter of market is one which must be 

 considered, since for all articles which cannot be 

 shipped on a six days' voyage, the cultivator is limited 

 at present to but one city of about 30,000 inhabitants 

 and another good-sized town. Again, the highly devel- 

 oped horticulture of California lies between Hawaii and 

 the great American markets. These home towns, how- 

 ever, are likely to double and treble their present popu- 

 lation during the next few years, and while there are 

 to-day many tons of fruit nn.l v.-t'.'t-.l.l.-^ imported from 

 California on every cold-Nt<ir:i:i ~:-;;hi. r which arrives,

regarding the market. An ■ : ,ii^ and vege- 



tables during the winter sea-. in i^liiijM.I t.i he found in 

 California, and a colony of Americau settlers is now de- 

 veloping this trade. 



Many minor industries are being tried, such as the 

 cultivation of the vanilla bean, varioi^ fiber plants, the 

 castor oil bean, and the like, and doubtless some of these 

 will prove valuable additions to the agriculture of the 

 country. The future of Hawaiian horticulture is not an 

 easy subject upon which to prophesy at the present 

 time, but one upon which many greatly interested in 

 the country's welfare are now thinking. A government 

 experiment station is greatly needed to aid in the solu- 

 tion of some problems connected with the subject.
