and, soot is composed of the grossest part of 

 the smoke. That which flies out of the chimney 

 is the best part of all. 



208. In case of a want of wood wherewith to 

 begin the fire, the fire may be lighted precisely 

 as in the case of paring and burning-. If the 

 kiln be large, the oblong square is the best 

 figure. About ten feet wide, because then a 

 man can fling the earth easily over every part. 

 The mode they pursue in England, where 

 there is no wood, is to make a sort of building 

 in the kiln with turfs, and leave air-holes at the 

 corners of the walls, till the fire be well begun. 

 But this is tedious work ; and, in this country 

 wholly unnecessary. Care must, however, be 

 takeu, that the fire be well lighted. The 

 matter put in at first should be such as is of 

 the lightest description; so that a body of earth 

 on fire may be obtained, before it be too heavily 

 loaded. 



209. The burning being completed, having 

 got the quantity you want, let the kiln remain. 

 The fire will continue to work, 'till all is ashes. 

 If you want to use the ashes sooner, open the 

 kiln. They will be cold enough to remove in 

 a week. 



210. Some persons have peat, or bog earth. 

 This may be burnt like common earth, in kilns, 

 or dry, as in the paring and burning method.
