are estimated to cost 10l. each. The least number generally required, (with good success,) for a ten-pot furnace, is from ten to fifteen pots per annum; but some manufacturers have set as many as fifty new pots in one year. Not merely is the expense of the pots to be considered, but the disappointment in not being able to execute orders that may be pressing, and the loss of metal running out of the broken or cracked pots through the furnace; whilst the fixed expenses for fuel and establishment are the same for the production of a small as for a large quantity of manufactures. During the Excise reign, no pot could be moved from the spot where it was dried, to be placed in the annealing arch, without a notice in writing to the supervisor; a second notice was required for gauging; a third for setting it in the furnace, again for filling the pot, and another for ladling it out; whilst the maker was forced to comply strictly with the act of parliament, by giving the officer six hours' notice for each of these intricate and vexatious requirements.

Foreign melting pots are usually made in wooden moulds, lined with cloth: if small, this plan answers where a great number are required; but British manufacturers almost invariable build their pots without moulds. The old and new clay being mixed together, and allowed to be saturated fully with water, the process of kneading by men's feet is repeated three times over, until the mass has a pasty consistence. It is then rolled into small pieces, about the size of a sausage; these wet clay-rolls are placed together (upon a lead slab) to the thickness of full four inches, to form the bottom, which is beaten with a wooden mallet, and pressed with the hand; the sides are raised by pressing the clay
