In order to avoid abuses related to the demarcation of lands for sowing which are eventually not tilled, it is established that the person who occupies one 'albar' [field?] has to cultivate it inmediately […],  the person who did not cultivate them for three consecutive years shall lose the right [of cultivation], without considering cultivation the mere indication [of the land] with one or two furrows, but he has to cultivate in the three years and to sow in the fourth.
