Section 21
SEC. 21. Any non-Christian Filipino who has not applied for a home-stead, desiring to live upon or occupy land on any of the reservations set aside for the so-called "non-Christian tribes" may request a permit of occupation for any tract of land of the public domain reserved for said non-Christian tribes under this Act, the area of which shall not exceed four hectares. It shall be an essential condition that the applicant for the permit cultivate and improve the land, and if such cultivation has not been begun within six months from and after the date on which the permit was received, the permit shall be cancelled. The permit shall be for a term of one year. If at the expiration of this term or at any time prior thereto, the holder of the permit shall apply for a homestead under the provisions of this chapter, including the portion for which a permit was granted to him, he shall have the priority, otherwise the land shall be again open to disposition at the expiration of the permit. For each permit the sum of one peso shall be paid.
