 One of these demands (which it took place in 1740) required the use of Native Americans of the missions on the farms of the settlers as labor, and the right of the Isleños to trade their products in the presidio.However, "the missionaries appealed to the Viceroy, and they managed to retain their privileges".Travieso sent another demand in 1756, which was directed against the monopoly and rights that the missions had on the lands and waters surrounding the villages, to which the Canarians had no access.
