118 SUMMER IN A BOG. 



posed on the ground germinate in the spring. 

 I call that hardy. 



Nature, which seems to resolve herself into 

 one dominant instinct to perpetuate — to multi- 

 ply and replenish the earth — ^has wonderful 

 methods of accommodating her productions to 

 their environments. 



The depth in the ground wlhich the root 

 seeks, placing it beyond the reach of the se- 

 verest cold, classes this vine with the ipomea 

 ("man-of-the-earth") which is one of the great- 

 est pests of the farm. The acquired hardiness 

 of the bulblets calls for a word of caution as to 

 their disposal in the fall. Like the seeds of 

 other cultivated plants which take kindly to the 

 wild state, the morning-glory, the "lace-plant," 

 or wild carrot, and others, they should be care- 

 fully burned. Here is a good place to apply the 

 ounce of prevention. If carried with other 

 refuse into the country it is certain to spread. 



While pursuing my inquiries in regard to 

 this plant, a curious reply was received from 

 a botanist as to its classification. The letter 

 has this remark: 



"I must say that I do not know whether it should 

 go into the State Flora or not. It does not seem to 

 seed at all, and is not able to spread beyond the gar- 

 den in which it was originally planted."
