year, so as to be off in time for a winter crop of wheat or 

 rye. Broad cast of the legumes as a cover, be preferable ; 

 though drillmg will be highly useful. Potatoes may occupy 

 a part, to be taken off in time for wheat. 3. Clover sown in the 

 winter grain. 4. Clover. This, course will be preferred in 

 a competition, unless the society shall be convinced, by the 

 results oi another course, that in practice, turns out better. 

 Manure admitted ; but the best products, with the least ar- 

 tificial manure, will be preferred. A gold medal for the best ; 

 and one of silver, for the second best experiment. 



The object of both the above premiums is, to introduce a 

 practice, found very beneficial where it has been fairly tried ^ 

 and to place the experiments in the hands of spirited and in- 

 telligent agriculturists, who will do complete justice to them- 

 selves, and the subject recommended to their exertions. 



4. Cover of Leguminous Crops. 



For the best and greatest crops of beans, pease, or other 

 legumes^ of th© kind beiore mentioned, sown broad-cast, as 

 covering on fallows, preparatory to winter grain. Not less 

 than five acres, and left clean and fit for wheat. These crops 

 ameliorate, and do not exhaust like all culmiferous plants 

 and those whose seeds produce oil. Oats — the worst and 

 most ruinous to succeeding winter crops. 



The object is, to introduce the practice of valuable and 

 improving covering crops, in preference to naked fallows, or 

 exhausting covers. A silver medal, or fifty dollars. 



5. Destruction of perennial xveeds. 



For the best set of experiments calculated for the destruc- 

 tion oi perennial weeds. The daisy or Maij weed^ ransted^ 

 garlic^ and St, Johri^s ivort^ to be particularly aim.ed at and 

 noticed. A botanical account oi th^ \Y&G^ds com-VCionly infesting 

 our fields, will highly recommend these experiments ; and 

 communications, relative to all or any of those enumerated, 

 will be gratefully received. This account should specitdly
