Method of making 
washed, the floor on which it is spread, and the ware 
house in which it is deposited, exhibit sufficient proofs of 
this; so also do the operations of beating, carding, spin 
ning, and weaving the wool, and those of shearing, comb 
mg, and fulling the cloth. It is indeed true that the 
scattered wool, produced from these various processes, is 
collected with some care ; but many of them are of such 
a nature, that the waste wool resulting from them, either 
is dirty, and mixed with other substances, or it is cut so 
short, that it is rendered incapable of being again used : 
in either case, the manufacturer throws it on the dung- 
hill. The making of the soap here described furnishes 
him with the means of bringing all these into use ; nothing 
more being requisite than to collect them in the baskets 
in which the wool is washed, and to wash them careful- 
ly ; as well for the sake of cleaning them, as to separate 
from them all foreign substances. When washed, they 
may be laid by till wanted. 
We may also, with equal advantage, make use of the 
cuttings and shreds of woollen cloth, which are found 
in the shops of woollen drapers, tailors, &c. and likewise 
of all sorts of garments, or other woollen articles, after 
they have been worn till they will serve no longer. 
On the Preparation of the Soap . 
When the ley is made, and the wool procured, no 
thing remains to be done, but to bring the ley to a boiling 
heat in a common caldron. When it is brought to that 
degree of heat, the wool is to be thrown in, a little at a 
time, and the mixture is to be stirred, that the solution 
may go on the faster. A fresh quantity of wool should 
not be added, until the preceding quantity is dissolved : 
and the process should be stopped, as soon as we find that 
the liquor will not dissolve any more wool
