When said coal arrives at its destination, the said carrier shall cause the same to be weighed at that point, provided it has scales at that point, and if not, then it shall cause said coal to be weighed at the nearest track scales on its line between the point of shipment and the point of destination, and if the weight of said coal at the point of delivery is less that the weight set out in the bill of lading, the carrier delivering to the consignee shall be liable to the consignee for all deficiencies in weight, less the natural shrinkage, which shall not exceed one percent (1%) for a one hundred fifty-mile haul or less and one and one-half percent (1 1/2%) on more than a one hundred fifty-mile haul; and the measure of damage of the consignee for such deficiency or shortage shall be the value of the deficiency if the freight has not been paid; and in weighing cars of coal they shall be detached from the train and in the event the loss or shortage does not occur on the delivering line, the carrier delivering to the consignee shall be entitled to recover from the carrier upon whose line the loss or shortage occurred, such amount for the loss or shortage as the carrier delivering to the consignee may be required to pay to the consignee as may be evidenced by any receipt, judgment, or transcript thereof.
