Section 69
SEC. 69. From every invoice of railroad iron or steel, or any other similar goods, a sufficient number of bars of equal length shall be weighed in order to ascertain the average weight thereof, such number of bars to be counted, and the proper returns made as in the ease of any other merchandise but if the weight as shown by the returns of the weigher does not vary more than five per cent from that stated in the invoice, the entry shall be liquidated at the invoice weight. If the interested party does not accept the increase in weight arising from the above method of appraisal, the entire consignment may be weighed, but if he does accept the proposed increase in weight the appraisement may be considered as ended.
