52. How stoppage in transit is effected. - (1) The unpaid seller may exercise his right of stoppage in transit either by taking actual possession of the goods, or by giving notice of his claim to the carrier or other bailee in whose possession the goods are. Such notice may be given either to the person in actual possession of the goods or to his principal. In the latter case the notice, to be effectual, shall be given at such time and in such circumstances, that the principal, by the exercise of reasonable diligence, may communicate it to his servant or agent in time to prevent a delivery to the buyer.

(2) When notice of stoppage in transit is given by the seller to the carrier or other bailee in possession of the goods, he shall re-deliver the goods to, or according to the directions of, the seller. The expenses of such re-delivery shall be borne by the seller.
