Section 70
SEC. 70. Whenever a permit or order directs that goods be weighed and a special return be made therefor, the weigher shall weigh the goods designated and make a return separate and distinct from any other without delay. If the merchandise has been shipped before the order to weigh is received by the weigher, he shall indorse such fact on the back of the order and return it to the surveyor. Returns of the weighing of a cargo must be made to the collector within six days after the vessel has been discharged. Certificates or copies of weights shall be furnished by the surveyor at ports where there is such an officer, elsewhere by the collector.
