XXII. An account of a new and cheap method of preparing pot-ash, with observations

The agriculture society at Manchester has long recommended the making of reservoirs for the water which flows from dung-hills in farm yards. This water is strongly impregnated with the salts and putrid matter of the dung-hill, and by stagnation it acquires a much higher degree of putrescence, and probably becomes proportionably more replete with salts. When thus collected and improved, it is pumped into an hogshead, which being drawn upon a sledge, or small cart, is conveyed into the meadows, for the purpose of sprinkling them with this rich manure.
