Suhsequent History of Croj)s on Different Plats. 



Plats 11 and 12. — The frost affected the crop somewhat 

 b}' heaving of the soil ; the growth was thin and of a light 

 color except in some instances where a deep color and large 

 growth was noticed. A subsequent examination showed in 

 these cases an exceptional development of tubercles on the 

 roots. The crop was harvested June 19. 



Plat 11. — Crop weighed green 200 pounds. 



Plat 12. — Crop weighed green 285 pounds. 



On account of unsatisfactorj" condition of the plats both 

 were ploughed July 15 and reseeded on July 30, 189(5, with 

 10 pounds of sweet clover seed each, to notice whether a 

 more liberal infection of the soil with suitable bacterium 

 thus secured would result in better and larger returns. Nov. 

 1, 1896, the crop was looking well and was one foot in 

 heiglit. The dark spots of growth had spread greatly. 



Plats 13 and 14. — The crops upon these plats looked 

 well in the fall and during the succeeding spring. The crop 

 was cut before it had reached lull bloom, June 23, on account 

 of its being badly lodged ; they were hai-vested as hay 

 June 29.
