Turf may be 

 charred* 



Advantages 



Turf is alfo fufceptible of amelioration, efpecially the fur- 

 fece turf, the crumbling turf, and the mountain turflikewife; 

 for it may be reduced to charcoal, and will thus fei ve for every 

 work which requires fife; and in this cafe it yields neither fmell 

 nor fmoke. The more ftrongly the turf is compreflfed before 

 its carbonization, the more excellent is the charcoal. 



Tocompenfate for the inferiority of turf to wood, granting 

 from the ufe of ^^ £ ^ ; nter j or ^ its u f e w jjj p revent the great price which 



will otherwife neceffarify be paid hereafter for timber for build- 

 ing, and will admit of the woodlands being proportionally re- 

 Cabbages, &c duced ; the places alfo where the furface turf has been dug up, 

 where Itlha* ^ !t nas not ^ een * rom to ° g reat a depth, may ferve for fitu- 

 becn extracted, at ions wherein to plant cabbages, beets, and madder, or they 

 Its ufe admits of w ill ferve forfifh ponds. The ufe of turf will admit of the 

 roanufaaories multiplication of manufactories which ufe fire, of mines and 

 where fire is forges j aged perfons and children may be employed in pre- 

 paring it ; its afhes form a good manure, and the mould which 

 falls from it may eafilybe converted into alhes.

The author's IT was my intention to have poftponed troubling you with 

 xeafon for early X ^ Q f n ow i n g experiments upon the condenfation of the gafes, 

 until I had brought them to a greater degree of perfecliori ; 

 but being informed that feveral of them have already, by 

 means of which I am ignorant, and probably in a mutilated
