MAN-OF-THE-EARTH 



SO that really it should be given the field when once placed. The 

 seeds should be cut or filed before planting; the outer covering 

 is so strong that, without this help, fully one-half will not germi- 

 nate. 



MAH-OF-THE-EARTH. WILD POTATO VINE 



Ipom&a pandurhta.

 tiful white Morning-glory flowers. Perennial. Sandy fields and banks

 cles one to five-flowered.

A vine that can achieve a massive root weighing twenty pounds 

 demands respectful treatment, for if it once becomes established 

 in a garden, it will probably remain. One should certainly think 

 twice before planting Man-of-the-earth. The blossom is the 

 beautiful cup of the Morning-glory, white with a purple eye, open 

 all day long, drinking in the sunshine. On a sandy bank where 

 little else will grow it is an acquisition.
