the crop harvested, the buckwheats ranked in this order : 

 silver-hull, Japanese, common variety. 



Stachys tubers {Stachys affinis), little tubers sent on by 

 the Department of Agriculture in Washington, were planted 

 (one row) April 21. They came up May 1 ; had reached a 

 growth of nine and one-half inches September 19, when 

 suckers came out. Frost did not affect the foliage before 

 October 28. The tubers were left in the ground for obser- 

 vations during the coming year. The tubers are considered 

 a substitute for potatoes in the south of France. 



Chinese potato bulblets, sent on for trial as a potato 

 substitute by the United States Department of Agriculture. 

 They were planted April 21, two feet apart in the row; 

 came up May 30, and were from two to three inches high 

 July 14. The plants send out runners from eighteen to 

 twenty inches in length. Leaves suffered from frost October 

 1. The bulblets were left in the ground for observations 

 during the coming year. 



Prickly comfrey {Symphytum officinale), one row. The 

 roots for planting were kindly presented by Col. J. D. W. 

 French, and were put in the ground Oct. 11, 1890, two 

 feet apart in the row. They produced a luxuriant growth 

 during the late spring; began to blossom June 5, and 

 reached a height of twenty inches, with numerous highly 

 foliaceous branches. The blossoms were removed, to pre- 

 vent a seeding out. The plants kept green until the middle 

 of October. 



English rye-grass {LoUum perenne), three rows. This 

 variety of grass has been raised for a number of years on 

 various fields of the station farm, to ascertain its decree of 

 resistance to the influence of our winter climate. After 

 repeated trials, it is safe to say that it is in an exceptional 

 degree liable to winter-killing in our locality. One-half of 

 the field was winter-killed during the previous winter. 



Campbell's spring wheat, three rows, two feet apart. 

 Sown May 4 ; appeared above ground May 22, and was ripe 

 for cutting August 22. It made a rather light growth. 



Winter wheat, twelve varieties, sent on from London, 

 Eng. (Nos. 1-12 below). Each variety occupied five feet 

 in the row, with one foot of space between them. They
