 otherwise ; and as the interest upon the original outlay- 

 is so important an item, great judgment and economy 

 are required in forming young plantations. 



There are several ways of valuing mature or full- 

 grown plantations, which may all prove sufficiently 

 correct ; but the following appears to the writer the 

 most commendable : — If the subject is purely a fir or 

 larch plantation, ^fie whole is put down in feet ; but 

 if the plantation is a mixed one, consisting of a great 

 variety of trees, the following is the simplest and best 

 mode : — Every tree is marked in some way, if to stand 

 uncut, with chalk, which is quite sufficient, and soon 

 washes off with the rain without disfio-urement ; but 

 if to be cut down, the bark should be removed with a 

 marking axe, and a number put on in any way found 

 convenient. The following is the form in which the 

 valuator's book is filled up in valuing a general mixed 

 i^lantation : — 



is for oak, worth 30s. the tree ; A, ash, value 25 s. ; 

 E, elm, worth 203.; S C, sweet chestnut, value 30s.; 

 L, larch, value 20s. ; and so on with all the others. 

 After reaching home the whole is arranged and classi- 

 fied, and each species of tree put in a column by itself.
