Section 69
SEC. 69. Whenever any province, municipality, or other branch or subdivision of the Government shall need any portion of the land of the public domain open to concession for educational, charitable or other similar purposes, the President, upon recommendation by the Secretary of Agriculture and Commerce, may execute contracts in favor of the same. in the form of donation, sale, lease, exchange, or any other form, under terms and conditions to be inserted in the contract; but land so granted shall in no case be encumbered or alienated, except when the public service requires their being leased or exchanged, with the approval of the President, for other lands belonging to private parties, or if the National Assembly disposes otherwise.
