AGRICULTURE. 



He found one little plant which had been cut 

 off about an inch above the ground, and had put 

 out a new growth. "It bore three pods, each 

 containinor one seed."'"*' These were 

 planted the next spring, resulting in 

 two dwarf plants. P>om these, by 

 continued selection, the Burpee 



Bush Lima was de- 

 veloped. 



Suggestion : If 

 the school does not 

 own a garden plot, 

 the teacher should 

 secure a vacant lot 

 by paying a small 

 rental, or, perhaps, 

 b )' sharing the 

 products. If this 

 is not possible, then 

 the work of pruning 

 and cross-pollina- 

 tion must be done by those members of the 

 class who can have access to private gardens, 

 and their results reported to the class. 



If it is desired to secure a stout, bushy plant, 

 instead of a tall, single-stemmed one, let the 

 student take the chrysanthemum or cosmos for 

 example.
