 stopped at pleasure ; 'while, by the ordinary methods, the 

 same effects can only be produced by artificial and empi- 

 rical means. 



"When it is wished that wood should be developed, 

 the vines (roots) must be placed in a trench, and covered 

 with three or four inches of earth with which have been
