Section 17
SEC. 17. No patent shall issue under the provisions of this chapter until the land has been surveyed under the direction of the Chief of the Bureau of Public Lands and an accurate plat made thereof. The cost of such survey must he borne by the purchaser, if a corporation or like association, and if the survey be made in advance of the regular surveys of the Islands; but where the purchaser is an individual the cost of the survey shall be borne by the Insular Government. Patents shall not issue until after the expiration of five years from the date of the award, and before the same shall issue the purchaser must show actual occupancy, cultivation, and improvement of the premises for a period of five years immediately succeeding the date of the award, and that he has not sold the land or in any manner encumbered the title.
