Sugar history in the Hawaiian Islands is filled with pioneering. In sailing ship
days, Hawaiian sugar growers were many months from sources of supplies and from markets. This isolation built up among the Hawaiian growers an enduring spirit of cooperation. Growers shared with one another improvements in production. Without government aid of any sort, they built great irrigation projects. Without government help, they set up their own research and experiment organization. Pioneering together over the years, they have provided Hawaii with its largest industry.
