Section 56
SEC. 56. Postmasters at minor post-offices shall be required to deposit all surplus postal fluids in their hands at the close of each month with a depository to be designated by the Director of Posts, which shall he a larger post-office, convenience of location being considered. In case the receipts of any post-office are insufficient to meet its authorized expenditures, such deficiency may be met by a transfer draft of the Auditor upon a post-office receiving such deposits of surplus postal funds. Depository post-offices shall deposit their surplus receipts with the Treasurer of the Islands as revenues arising in the Bureau of Posts.
