Chilworth Powder Mills, in the Parish of Saint Martha, in the County of Surrey. Trial [of William Tinkler and Richard Mountford] on an indictment, charging them as a nuissance; by which they were proved to be, not only no nuisance, but as safe as any, if not the safest, powder mills in the kingdom. Taken in short hand, by Thomas Jenkin, 2d April, 1817
