But, for reasons above stated, these results, in a different season and 

 in other circumstances, may vary. 



The weight of the stover, it will be seen below, docs not exactly 

 correspond with the grain, yet the largest yield produced also the 

 greatest amount of fodder.

Two acres of corn not included in the above were also planted with 

 different kinds of corn. One of these was mostly sweet. Of this 

 there was sold in the green state the amount of $41 T 2 ^. The bal- 

 ance at harvest time yielded 23 bushels of ears of sweet, 8 of pop, and 

 10 of a white corn, had of Rugglcs, Nourse & Mason. The other acre 

 was planted with seed corn from Hadley, Mass., and yielded 110 

 bushels of ears, of a very beautiful quality. These two acres were 

 fertilized with manure from the pigsty in 1853, at the rate of ten cords 

 to the acre, and the same quantity this year. Last year the product 

 was at the rate of 62£ bushels of shelled corn to the acre. This land 

 lies north of the institution. 



POTATOES. 



Of these there were nine acres in cultivation. 



The following experiments were made on the Sibley lot, containing 

 five acres ; soil light — rather sandy ; ploughed seven inches deep, 

 furrowed both ways, thirty-six by thirty inches, and planted with the 

 St. Helena potato. This field produced corn in 1853, and was then 

 manured with about seven cords of barn manure to the acre. This 

 year the crop was hoed twice, but not hilled at all. 



Lot No. 1. — This, like the others which follow, contained one acre. 

 It was manured with barn manure, one-half spread and ploughed in, 

 the balance put in the hill, at the rate of twelve dollars' worth to the 

 acre. Product, 5,189 lbs., or, at 60 lbs. per bushel, 864- bushels per 

 acre. 



Lot No. 2. — This was dressed with twelve dollars' worth of guano, 

 and produced 5,535 lbs., or 92-J bushels per acre. 



Lot No. 3. — This was dressed with twelve dollars' worth of Mapcs' 

 super-phosphate of lime, and produced 5,053 lbs., or 84J- bushels per 

 acre.
