Plats 11 and 12 were each seeded down with 8 pounds of 

 sweet clover seed. 



Plats 13 and 14 were each seeded down with 3 pounds of 

 mammoth red clover seed. 



Plats 15 and 16 were each seeded down with 3 pounds of 

 medium red clover seed. 



Plats 17 and 18 w^ere each seeded down with 2.^ pounds of 

 alsike or Swedish clover seed. 



Plats 19 and 20 were each seeded down with 4 pounds of 

 crimson or scarlet clover. 



Plats 11, 13, 15, 17 and 19 received their potash in form 

 of muriate of potash (80 to 82 per cent.) ; plats 12, 14, 

 16, 18 and 20 in form of hioh-grade sulphate of potash (95 

 per cent.). 



Subsequent History of Crops on Different Plats. 



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

 by 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 unsatisfactory condition of the plats both 

 were ploughed July 15 and reseeded on July 30, 1896, 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 iu ])etter and larger returns. Nov. 

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

 height. 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 full bloom, June 23, on account 

 of its being badly lodged ; they were harvested as hay 

 June 29.
