 but also for many other purposes, is obtained by the burning 

 of wood in closed stacks, and the charcoal-makers are by no 

 means indifferent as to the species and quality of the timber 

 used. 



(25.) Lastly, we may refer to the numerous and increasing 

 substances obtained by the distillation of the products of 

 combustion of wood of various kinds. Various tars, pitch, 

 wood-spirits, soot, &c., are still obtained by these means. 



Enough has been said to illustrate some of the principal 

 and various uses to which timber is applied in different parts 

 of the world ; that these will increase, rather than diminish, is 

 very evident to all who watch the progress of events, whence 

 we may safely conclude that the foresters' art is likely to 

 flourish for a long time to come.
