this and for our supply of wood to give to it the thousands 

 of acres not capable of profitable tillage, and the sides of our 

 roads and other grounds now either bare or exclusively de- 

 voted to other ornamental trees." (Agric. Kpt., '93, J. C. 

 Smock, 55.) 



"Owing to the depredations of the locust-borer, it is always 

 best to mix another species with the Locust. For this pur- 

 pose Primus serotina and the American Chestnut are excel- 

 lent. As with other leguminous plants, bacteroids, which 

 reside in a symbiotic state in tubercles on its roots, are able 

 in some mysterious way to accumulate nitrogen. The litter, 

 which is rich but thin, soon decays. Once established, the 

 locust hurst will never need renewal; hundreds of stool- 

 shoots and root-suckers are present to take the place of felled 

 trees on the admission of light. Besides a tap-root the Locust 

 has an extensive horizontal root system by which the soil is 

 held in place. It is for this reason used on railroad embank- 

 ments and dry soils subject to shifting." (Geol. Kpt, '99, 

 Gifford, 285.) 



"The seed ripens in September and should be gathered 

 during fall and winter. The pods containing the seed are 

 kept in a dry place over winter and the seed planted in the 

 spring. Spring planting is preferable to fall planting on ac- 

 count of danger from field mice during the winter. The seed 

 is thrashed out. Just before planting the seed should be 

 placed in scalding water, which will cause it to swell. If the 

 seed is not put in scalding water it will 'lie over' in the ground 

 and germinate the second year only. Sow t the seed in beds 

 where the young plants should remain one or two years, when 

 they may be set out permanently at four to six feet distance. 

 Do not plant them further apart than six feet. They may 

 also be grown from root cuttings or from sprouts. Trees 

 grown from seed are best as they are more healthy and possess 

 a greater reproductive power." (Hort. Kpt., '03, Meier, 

 213.)
