And, when drawn off, they may be used with profit on 



fresh ashes, as long as there remain in the lies any salts, 

 which may be discovered by the taste.

The lie that runs off for use^ should be filtered as it passes 

 the bottom of the tub; and also as it runs into the receiver; 

 which process may be performed without any expense or 

 inconvenience. Previous to boiling the lie, it ought to stand 

 twenty four hours; and then be drawn into the kettles 

 w^itli great care, so as to leave all the sediment behind. 

 Every precaution should be taken to let nothing fall into 

 the lies previous to, and w^hilst boiling. Therefore, that 

 injurious practice of laying wood on the kettles for drying, 

 must be avoided. 



Strong lies may always be boiled half away in the first 

 operation, and others much more : after which they must 

 be taken with care out of the kettles, and put into a receiver 

 at hand. Being so shifted, a very small quantity of unslack- 



w 



ed lime may be put into it, which serves to clarify, and at 

 the same time, renders the lie more pungent to the taste. 

 Or, a quantity of lime may be mixed with the ashes, which 

 will answer the last purpose. 



After standing quiet until it cools to the state of blood 

 heat, it must be again shifted ; and in drawing off the lie in 

 every instance, the utmost care must be taken that all the 

 sediment, which is generally a chalky earth, is detained ; 



which process will effectually separate all the common salt :
