practice. It was formerly the practice to deposit deeds and other things in the hands of third persons, to await the performance of covenants, upon which they were to be redelivered to one of the parties. When one of the parties contended that he was entitled to such things, and the other denied it, and the claiming party brought an action of detinue for them, the defendant was allowed to interplead, and thereupon he prayed for a monition or notice to compel the other depositor to appear and become a defendant in his stead. This was called a process of garnishment.
