Any cattle owner, as soon as his cattle became sick as a consequence of smallpox or any other contagious disease, shall report the Secretary of the Village Council so the persons in charge of the field demarcation ['amojonadores'] could indicate a field [where to take the sick cattle in], informing [also] the persons interested in the grass field or mountains to be demarcated. A similar declaration shall be made by the cattle owner within forty days after the last animal had recovered from its illness, removing then any ban upon the movement of the cattle ['dando por libre entonces todo el ganado'], upon pain of 4 duros.
