THE TRADE OP HAWAII. 



Statistics have recently been published by the Bureau of Statistics of the 

 Department of Commerce and Labor, showing the trade returns between Hawaii 

 and the United States mainland for the twelve months ending June, 1906, as com- 

 pared with the previous fiscal year. A careful analysis of the returns show that 

 during the year just ended, encouraging progress has been made, chiefly in what 

 are known as our diversified industries. The shipments to Hawaii from San 

 Francisco, New York and Los Angeles in eacn case decreased during the year in 

 question, while Puget Sound increased its shipments from $738,380 to $1,266,367. 



With regard to Hawaiian exports to the mainland our staple product only 

 amounted to $23,840,803 as against $33,946,036 in the previous year, leaving the 

 enormous deficit of $10,105,233. It is, however, gratifying to learn that our 

 exportation of refined sugar increased by over half a millon dollars during the same 

 period. Tlie refining of sugar in Hawaii is confined to one plantation and is among 

 one of the newest of our industries. The increase in this direction may therefore be 

 regarded as of special importance. 



Exportation of honey and bees-wax increased to the extent of $46,450, coffee 

 increased $74,976, canned fruits increased $85,706, hides and skins $42,333, leather 

 $14,592, tallow $7,046, rubber $1,028. and rice $141,598. 



The increase in canned fruits is chiefly attributable to the development of the 

 pineapple industry, and this item will no doubt continue to develop with marked 

 strides for many years. The export of rubber will, in a very short time, figure con- 

 spicuously in the return and will probably form one of our most valuable assets. 

 The production of leather, another of our new industries, has also materially 

 increased, and promises to still further develop. While the sales of Hawaiian rice
