The planters of the Delta, on their transfer to Spanish domination, saw indigo, the chief product of their lands, shut out of market. French protection was lost and French ports were closed to them. Those of Spain received them only into ruinous competition with the better article made in the older and more southern Spanish colonies. By and by kinder commercial regulations offered a certain relief; but then new drawbacks began to beset them. Season after season was unfavorable, and at length an insect appeared which, by the years 1793-94, was making such ravages that the planters were in despair.
