This is great to have on hand if you are researching early Texas settlers. Land terms: Vara 33 1/3 inches; League 4,428.4 acres; Labor 177.1 acres tillable land for one farmer; Sitio one square league for ranching; Hacienda five or more square leagues; Augmentation the amount of land due a settler because of change in his status (example marriage) to be added to his previous allotment. (Just think how large some Haciendas were.) Cassie
