As has been said, the general character of the mills was rude and primitive and it continued to be so up to 1850. The rollers were generally of wood and the kettles in which the juice was boiled were whalers’ trypots. The buildings were adobe or simple grass huts. Only one grade of sugar was made. The juice was boiled to a thick syrup and put into coolers to grain, after which the granulated mass was packed in mats, bags, boxes or barrels with perforated bottoms for the molasses to drain off. The mills were run by bullocks, horses and in some cases by water power, and were fed by hand, one stalk at a time. The whole process, both in the field and in the mill, was very crude and imperfect. The value of the sugar exported from the islands from 1836 to 1841 was $36,000 and that of the molasses for the same period $17,130. An article by the late William Ladd on the “Resources of the Sandwich Islands,” published in the “Hawaiian Spectator” for April, 1838, speaks thus prophetically of the manufacture of sugar, then in its infancy: “It is a very common opinion that sugar will become a leading article of export. That this will become a sugar country is quite evident, if we may judge from the varieties of sugar cane now existing here, its adaptation to the soil, price of labor and a ready market. From experiments hitherto made, it is believed that sugar of a superior quality may be produced here. It may not be amiss to state that there are now in operation, or soon to be erected, twenty mills for crushing cane propelled by animal power, and two by water power.” Just here it may be remarked that at that time the price of labor was a potent argument in favor of making the islands a sugar-producing country, for native labor was available in abundance and the current rate of wages was from 12½ cents to 37½ cents per day, or $2.00 to $5.00 per month. In an article on commercial development,[40] Thrum says: “Hawaiian produce in the early days had to seek distant markets, for we find shipments of sugar, hides, goat skins and the first shipment of raw silk moving to New York per the bark _Flora_ in 1840. A trial shipment of sugar was sent to France, but it did not offer sufficient encouragement for any renewals. The Sydney market was also exploited with sugar, where it obtained better figures than similar grades of Mauritius.” Between the years 1840 and 1850 a cane field and rude mill in Lahaina, Maui, were owned by David Malo, a well-known Hawaiian, who made molasses and sold it for home consumption. His apparatus consisted of three whaling-ship trypots set up on adobe and stone mason work. The crushing was done with wooden rollers, strengthened by iron bands. In 1841, Kaukini, governor of Hawaii, planted about one hundred acres of cane in Kohala and the crop when harvested was ground under contract by a Chinese named Aiko.
