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.
