CHAPTER IV. 

 CHOICE OF SOIL AND SITE. 



IT would be possible, under this heading, to write 

 very fully of the subject of geology, but we fail to see 

 the benefit which would accrue from it. As before 

 stated, it is of great importance that the forester 

 should possess an elementary knowledge of geology ; 

 but that he should be a geologist, in the true accepta- 

 tion of the term, we do not for one moment imply. 



It stands to reason that he should know something 

 of the earth's crust with which he has to deal ; how 

 this crust has been formed, and how, by volcanic 

 agency, each separate layer has been brought to the 

 surface for the use of man. He should know, too, 

 sufficient of the subject of structural or solid geology 

 to follow intelligently the various diversities of surface 

 soils. 



He should be able (when called upon to deal with 

 areas outside his own locality) by reference to a 

 geological map, to obtain an idea of the nature of the 

 soils likely to be found thereon. Not that structural 

 and surface geology are so closely analogous as to 

 render it possible to infer that one exists on account 

 of the presence of the other, but that there will be a
