In Broome v. The United States, 56 U.S. (15 How.) 143 (1854), it was held that a collector's bond might be deemed to be delivered when it was put in a course of transmission to the Comptroller of the Treasury, whose duty it is to examine and approve or reject such bonds. That decision proceeded upon the ground that the act of Congress requiring these bonds, and their approval, had allowed the collector to exercise his office for three months without a bond; and that consequently the approval and delivery were not necessarily simultaneous acts, nor need the approval precede the delivery; and the distinction between bonds of collectors and those of postmasters is there adverted to.
