1. Oak, from 1 cubic foot dimension and upwards. 



2. Ash, ditto ditto 



3. Larch, from 3 inches quarter girth and upwards. 



4. Sycamore of large size. 



5. Scotch Fir and Spruce of large size, and poles for pit 

 props. 



6. Birch and Alder. 



7. Beech and English Elm, trees and poles. 



8. Poplar, Lime, and Firs, other than Scotch and 

 Spruce. 



The demand, of course, varies in different parts of the country, 

 but the above gives a pretty good general idea of the comparative 

 demand for the kinds named in the order given. 



The next table following is intended to show what I believe 

 might be accomplished on one acre of poor land in a given time, 

 supposing the acre to be pure forest — that is all of one sort of 

 tree. The average from a general mixture may also be reckoned 

 approximately from the same table.

What I want to show here is the relative bulk of each kind of 

 tree under equal conditions on the same ground, and the sizes 

 given will be found to be pretty fairly constant everywhere. The 

 money value of an acre of timber depends in the first instance 

 upon the weight of the timber per acre, which may be reckoned 

 by the number of cubic feet ; and next upon the price per foot 

 that can be got for the trees as they stand in the wood ; and, 

 as has been already explained, this price depends upon situation 

 and circumstances. It will be seen from the table that the
