SECTION 1. Section eight of Act Numbered One hundred and ninety-eight, relating to official transportation, as amended by section two of Act Numbered Two hundred and thirty-seven, is hereby amended by striking out said section and substituting therefor the following:
"SEC. 8. The Insular Purchasing Agent shall contract with the interisland transportation lines and with railroad companies for the transportation of such officials as may be required by their official duties to go from one point to another in the Archipelago, and shall issue transportation requests to such officials upon said companies for passage according to the terms agreed upon. Payment of these transportation requests shall be made by the disbursing officer of the Department, Bureau, or Office against which the cost of the transportation is properly chargeable, and each Department, Bureau, or Office shall submit for appropriation, with the regular estimates, the amounts which will probably be required for the payment of such transportation expenses. The Insular Purchasing Agent shall furnish transportation requests, with proper stubs, in book form, signed by him, to the heads of such Departments, Bureaus, and Offices as may be designated by the Civil Governor, and to each provincial treasurer, to enable such officers to countersign and issue the same. The provincial treasurer will issue requests only upon the order of the head of the proper Insular Bureau for any Insular officer or employee, whose official duty requires him to proceed from the province of the provincial treasurer to some other part of the Archipelago. Each officer and provincial treasurer receiving such blank requests shall be accountable for them to the Insular Purchasing Agent. The Insular Purchasing Agent shall, with the approval of the Insular Auditor, make proper regulations for the issuing of such requests by the provincial treasurers and other officers to prevent their use for improper or unauthorized puposes."
