16 STRONG DRINK AND TOBACCO S3I0KR 



I shall have to speak of the method of examiuing 

 leaf structure when treating of hops and tobacco, taking 

 it for granted that the reader knows what books to read 

 amongst the numerous published works on the micro- 

 scope and its management. For the rest, successful 

 study should depend less on books than on hearty desire 

 and a strong will.
