Pound (Anglo-Sax. pund, a fold), in law, a pen, pinfold, or enclosure of any kind authorized by law and belonging to a town, city, or county, in which domestic animals that are wandering about, or trespassing, may be confined until claimed and taken out by the owner, by due process of law or in a lawful way. The practice of impounding stray or mischievous cattle is extremely ancient in England, and was adopted by the American colonies from their beginning. The whole process is carefully regulated by statutes in the United States, the provisions of which differ very much. In general they permit a sale of the property impounded for the cost of keeping, if it is not taken away and costs paid within a fixed time.
