EXPERIMENTS. 



The experiments undertaken were, in the main, aloncr the lines 



bej^un in the previous year, but, if possible to do so, an attempt will ])e 



made to extend the work to embrace other important lines of investi- 



jjation. 



CORN. 



As has been previously stated, the most important corn-g-rowin^ 

 section in the Hawaiian Islands is the Kula district, on the island of 

 Maui. This comprises some 7,000 acres on the leeward slope of 

 Hnleakala, at an elevation of between 2,500 and 5,0()0 feet. The soil 

 ranges in depth from inches to as many feet, and consists of a very 

 tine and powdery loam. This Kula region has been famous for its 

 fertility, the land having been in cultivation for sixty years. 



It was in this district that much of the wheat grown for export from 

 the Hawaiian Islands was raised during the time of the early gold excite- 

 ment in California. This district, in common with many others of the 

 group, is divided mainl}- into large holdings, but the (;orn land and the 

 land capable of the cultivation of corn is leased in parcels of small acreage 

 to Portuguese, .Japanese, and Chinese tenants. Many of these small 

 farms, if they may l>e termed such, especially those along the govern- 

 ment road which runs from Makawaoto Makena, have been in cultiva- 

 tion continuously, in some cases, for forty years. The climatic condi- 

 tions are such that the best results can not be counted on oftener than 

 three 3' ears out of live. Nevertheless the jnelds have in former years 

 been so heavj^ that the losses of the bad v'cars were more than made 

 up for by the intervening good seasons, and both the corn crop and 

 th(> potato crop have yielded large returns. As has been stated before, 

 the land is in itscdf extreme!}' rich, and its physical characteristics 

 are such that it would stand a good deal of poor cultivation. The 

 texture of the soil is so loose and friable that deep plowing and 

 thorough cultivation would l)e as easy here as on the black prairie 

 loams of the West. But good cultivation by the tenants of these
