Owners of negotiable grain warehouse receipts surrendered for shipment of grain or of grain in a public warehouse for which load slips only are furnished shall furnish the warehouseman with written instructions regarding the capacity of cars to be ordered from the transportation company and as to the manner of loading and billing shipments made in such cars as are furnished by the transportation company. The warehouseman shall load and bill all such shipments in exact accordance with instructions given, and is liable to the owner of the receipt so surrendered or of the grain for which load slips only are furnished for the amount of any excess freight paid, or for other damages suffered, by the owner of the receipt or grain resulting from the failure of the warehouseman to follow exactly the loading and billing instructions as given the warehouseman.
