Cap. 16 Art. 1967Retention of pledge for other debts.

If the same debtor contracts another debt with the same creditor subsequently to the delivery of the thing pledged, the creditor, in the absence of an agreement to the contrary, shall have, in respect of the second debt, the same rights on the thing pledged as are competent to him in respect of the prior debt, even though it has not been expressly agreed that the pledge should be made liable for the payment of the second debt.
