is a custom regulating the manner in which tin is obtained from waste-land, or land which has formerly been waste-land, within certain districts in Corn- wall and Devon. The custom is described in the leading case on the subject as follows: “Any person may enter on the waste-land of another, and may mark out by four corner boundaries a certain area. A written description of the plot of land so marked out with metes and bounds , and the name of the person, is recorded in the local stannaries court, and is proclaimed on three successive court-days. If no objection Is sustained by any other person, the court awards a writ to the bailiff to deliver possession of the said ‘bounds of tin-work’ to the ‘bounder,’ who thereupon has the exclusive right to search for, dig, aud take for his own use all tin and tin-ore within the inclosed limits, paying as a royalty to the owner of the waste a certain proportion of the produce under the name of ‘toll-tin.’ ” 10 Q. B. 26, cited in Elton Commons, 113. The right of tiubounding is not a right of common, but is an interest in land, and, in Devonshire, a corporeal heredita- ment In Cornwall tin bounds are personal estate. Sweet.
