Section 15. Preservation of identity of goods.

In order to permit at all times the identification of the goods deposited in a warehouse, and easy delivery therefrom, every warehouseman shall keep in his warehouse the goods of one depositor separate from the goods of other depositors, and also the goods of the same depositor separate from his other goods for which a separate receipt has been issued: Provided that where standardised and graded goods are stored in warehouse, subject to any agreement between the warehouseman and depositor the same variety of goods belonging to different depositors may be mingled together by the warehouseman, and each depositor will be entitled only to his portion of the goods according to weight or quantity as the case may be, as shown in his receipt.
