consumption was 17.5 per cent for the 10 years 1903-4 to 1912-13 

 over the preceding decade, compared with an increase of 9.1 per cent 

 of the world crop of sugar consumed in the United States. The 

 percentage of the sugar supply of the United States contributed by 

 domestic production during the decade ending with 1912-13, as com- 

 pared with the decade ending with 1902-3, increased 36.6 per cent, by 

 noncontiguous possessions an increase of 64.4 per cent is shown, 

 while the percentage contributed by foreign countries decreased 20.9 

 per cent. Thus it is shown that the domestic production and re- 

 ceipts from the island possessions have gradually replaced the im- 

 ports from foreign countries ; that is, the percentage of the total 

 supplied by foreign countries was lower in the latter decade, being 

 as low as 46.6 per cent, compared with 79 per cent, the highest for 

 the preceding decade. 



HAWAII. 



The principal industry in the Hawaiian Islands is the growing of 

 sugar cane and the manufacture of raw sugar. About one-fourth of 

 the entire population, slightly less than 50,000 people, are directly 

 engaged in this industry, and the remainder depend upon it to a 

 greater or less extent. The making of sugar practically continues 

 throughout the year, though the greater portion of the crop is har- 

 vested from November to July. 



The Federal census reported 86,854 acres under cultivation in 1899, 

 of which 65,687 acres, or 75.6 per cent, were planted to sugar cane. 

 The area in cane increased to 186,230 acres in 1909. The total value 

 of all crops in 1899 was $19,610,551, of which $18,033,515 was sugar 

 cane. In 1909 the total value of all crops was $28,535,677, of which 

 $26,305,747 was sugar cane. 



In 1909 the growing of sugar cane was reported by 1,028 farms, 

 and of this number 46 were equipped with mills for making sugar. 

 The production of cane was 2,239,000 tons in 1899, 4,240,238 in 1909, 

 and 4,900,000 in 1913. The yield of cane per harvested acre increased 

 from 34 tons in 1899 to 42 tons in 1911 and to 43 tons in 1913. The 

 annual production of sugar for the last ten years has been about 

 500,000 tons, ranging from 367,475 tons in 1903-4 to 612,000 tons in 

 1913-14. The production of sugar per acre harvested increased from 

 8,253 pounds in 1898-99 to 11,400 pounds in 1914-15. The extraction 

 of sugar per ton of cane was 230 pounds in 1898-99, 249 pounds in 

 1910-11, and 250 pounds in 1913-14. Practically all of the sugar 

 produced in the islands has been shipped to the United States, aggre- 

 gating 500,000 tons annually during the last ten years. The annual 

 shipments to the islands from the United States during the same 

 period amounted to more than 1,000,000 pounds of refined sugar. 

 Imports from foreign countries have been about 50,000 pounds an- 

 nually.
