gardens have improved under cultivation will see 

 possibilities in such plants as the thistle and the 

 burdock that are not revealed to casual inspection. 



Poisonous plants like the tomato and the potato 

 have been made wholesome within comparatively 

 recent times. 



The thistle and burdock have no poisonous 

 principle. Some species are wholesome and not 

 unpalatable even in their wild state, and all that 

 is required is to accentuate the good qualities that 

 the plants already possess in order to make them 

 worthy of membership in the coterie of garden 

 vegetables. 



— It should not be forgotten 

 that all of our present garden 

 plants were at one time wild, 

 and that to the wild we must 

 look for countless new 

 garden plants in the future.
