The frequent occurrence of a natural dense growth of a 

 blue variety of wild lupine, on sandy, unimproved, unpro- 

 ductive lands along the Connecticut River, suggested the 

 idea of trying the above described improved variety as a 

 green manure for the reclamation of abandoned farm lands 

 in neiffhborino- districts. 



The white lupine enjoys a high reputation as a green 

 manure upon a light, dry, sandy soil. The first season 

 (1884) was used for raising seeds ; and the second for test- 

 ing its value as a green manure. 



'Luzerne (Alfalfa). — Two varieties of this well-known 

 fodder plant — Medicago sativa and Medicago media — were 

 cultivated during the preceding year. Both were seeded 

 down broadcast at the same time ; they came up quite evenly. 

 Medicago media or sand luzerne soon, however, took the 

 lead ; they both produced fair crops. 



The plants passed well through a severe winter. As the 

 appearance of a foul growth rendered the continuation of the 

 experiment of doubtful benefit, it has been decided to repeat 

 the trial by seeding in drills to secure a better chance for 

 clean cultivation.
