takes three vessels, one after the" other, and presents them un-ij^aryand other 



der a third hammer, placed near the two first, and moved like "ses. 

 them by the same arbor, which carries a small tripping wheel, 

 moved by water. The vessel is placed on the anvil, so that 

 the hammer, v/hich is pointed at its striking extremity, enters 

 into its cavity. The workman holds the vessel, and shifts its 

 position with his hands and knees. Every stroke of the ham- 

 nVer leaves a slight cavity of the size of a pea, which forms dif^ 

 ferent designs, according to the motion which the workman 

 gives to the vessel. These outlines are not made for the sake 

 of beauty, but to give strength and firmness to the vessel by 

 hammer hardening it. The young girls, afterwards, take the 

 vessels and scrape the interior sides, as was done with the bot- 

 tom; and lastly, the v/orkmen, on two kinds of anvils, the one 

 plain and circular for the bottom, and the other semi cylindric 

 for the sides, completes their figure with a wooden mallet. 

 Small cracks sometimes appear in the vessel, which the work- 

 man close, and the matter is suffered to cool ; after which, 

 the cake, which now has the forrn of a tuencated cone, is carried 

 against a piece of iron bended two ways. Fig. 8, and drove 

 into the wooden block, which supports the gudgeon of the ar- 

 bor of the hammers. This doubly recurved iron serves to 

 retain the cake which enters under it, and by that means 

 allows the small tongs. Fig. 7, to raise up the edges of the two 

 great plates, which, in part, covered the seven small ones. This 

 being done, the vessels, or hammered pieces, are taken out 

 from within each other. The first is always perforated on ac- 

 count of the immediate purchase of the hammer, and that of 

 the air, which, partly converted into scales, fall out by 

 the immediate action of the hammer. As these vessels, when 

 taken out, are more or less bended, the assistant sets them to. 

 right by a few strokes of the hammer, after which the master 

 workman cuts their edges with the shears.

After the vessels are cut round, they are delivered to ano- 

 ther workman, who takes them to his separate shop to finish. 

 His first operation is to set the conical surface fair by means of
