forests, they are considered as accessory, or minor, produce. 

 A distinction is thus made between principal and minor 

 forest produce. 



A forest-owner is, as a rule, concerned only with the rough 

 conversion of the produce of his forest, so as to facilitate its 

 transport. Sometimes, however, and for certain kinds of 

 produce, it may he advisable for him to prepare forest pro- 

 duce in the form in which it is directly utilizable for various 

 industries, in which case he carries on auxiliary forest 

 industries. To deal with these industries fully is quite 

 beyond the province of the present book, and they will be 

 described only in such detail as the ordinary routine of 

 forestry requires. 



The matter of which the science of Forest Utilization, thus 

 extended, is composed, may be comprised under four principal 

 headings, which are as follows : 



I. UTILIZATION OF PRINCIPAL FOREST I'ROIHTK, WOOD. 

 II. UTILIZATION OF MINOR PRODI-CK FROM TRKKS.
