 and 4,£ inches broad, and this piece of turf is afterward di- 

 vided in two. 



In order that the pieces of turf may dry quickly, they mould Method of dry- 

 be placed on planks, and difpofed fo that the air might freely ing lt * 

 circulate between them, and that they could receive the rays of 

 the fun. 



When the turf is thus dried to a certain degree, it is placed Should not he 

 under (beds to compleat the drying; for if it was expofed to ^n'the'fuxT^ 

 the fun till it was entirely dry, it would lofe its ftrength and 

 burn like (haw. 



It is alfo difadvantageous to cut a large proviflon of it for or ke pt too 

 many years, for the lafi made is always the Deft. The upper Upper and lowe- 

 and lower beds are alfo obferved to be of inferior quality to beds of itthc 

 thofe in the midft ; the belt turf is that of a brown colour in-^Jj. £ ind d * j. 

 dining to black, is heavy, and its texture is traverfed by a brown and 

 fmall quantity of roots ; trhis kind produces a ftrong and laft ing heav y* 

 fire, and its fmell is very fupportable. The more it is of a Br 'g htbrown or 

 bright brown colour, the greater number of roots in it, and the 

 lighter it is, the worfe is its quality. This fort confumes more 

 fpeedily, and may ferve to advantage where a quick fire is 

 wanted; its odour, it is true, is very difagreeable, but itsathes 

 i are excellent. 



The turf which inclines to a grey or yellow colour, and 9 rey ' ™ y e1 |? w 

 which is mixed with reed, is always the worft fort, but always 

 good enough to heat kilns or ovens, and itsathes are good; 

 this fpecies is feldom found below the depth of two ells ; it is 

 reproduced after feveral years. 



The fecond fpecies of turf is the crumbling turf (moder-torf) , Second fpecies, 

 this kind is found more abundantly in Holland; its cutting and ^crumbling 

 preparation require much more pains than the furface turf. 



The third fpecies, or the mountain turf, is dug up from pits Third fpecies, 

 and galleries, and is reduced to regular forms like the preced- the mountain 

 ing kind. 



It is objected to the ufe of turf that it cannot be employed Wood not pro- 

 as a fuhftitute for wood in all the places where wood is burned; Pj* for fuel in 

 but it mould not be forgotten that wood itfelf is not fit for every tfta n turf, 

 work where fire is required ; that in order to be employed in 

 founderies it mutt be charred with much trouble, and with a 

 Iofs of two thirds of its weight, and that wood as well as turf 

 is of different qualities and produces different effecls.
