and one-third cords to the acre, a cord estimated to contain one hun- 

 dred and two bushels.* 



The remaining six acres were divided into six equal lots, were 

 manured at equal expense, and subjected to the following experi- 

 ments : — 



Lot No. 1. — This was fertilized with ten dollars' worth of reservoir 

 manure from the sinks of the institution, mixed with soil, estimated 

 at its comparative value with stable manure, and it produced 87 

 bushels of ears, or of shelled corn 43J bushels per acre. 



Lots Nos. 2 and 3. — These were dressed with ten dollars' worth 

 of guano each to the acre, and produced 144 bushels of ears, or 72 

 bushels of shelled corn, being 36 bushels per aero. 



Lot No. 4. — This was manured with ten dollars' worth of Mapcs' 

 super-phosphate of lime, and produced 85 bushels of ears, or of shelled 

 corn 424 bushels per acre. 



Lot No. 5. — This was dressed with ten dollars' worth of De Burg"s 

 super-phosphate of lime, and produced 101 bushels of ears, or of 

 shelled corn 50^- bushels per acre. 



Lot No. 6. — This was dressed with ten dollars' worth of ground 

 bone, and produced 90 bushels of ears, or of shelled corn 45 bushels 

 per acre. 



On Lots Nos. 2 and 3 the seed corn was destroyed twice by the 

 strength of the guano, although it had been composted (see note) for 

 some weeks. f The crop was therefore late, and much injured by the 

 drought. 



On lot No. 5, dressed with De Burg's super-phosphate of lime, the 

 corn was the heaviest and stoutest, yielding only one bushel of soft, 

 or pig, corn to the acre. 



Thus it will be seen that of these lots, side by side, similarly con- 

 stituted and cultivated, and fertilized at equal expense, the results 

 were as follows : — 



Guano, not fairly tried, produced . . . 36.6 per acre. 



Mapes' super-phosphate of lime produced . . 12J 



Reservoir manure produced .... I,;' " 



Bone manure produced 45 



De Burg's super-phosphate of lime produced . 50J 



* The barn manure was composed of 120 cartloads of loam, and 10 do. of 

 meadow muck, to 220 loads of stable manure, and, when composted, estimated to 

 be worth one dollar a load, or three dollars per cord. The fifteen acres produced 

 1,312 bushels of ears, or G56 bushels of shelled corn, or at the rate of 43 11- lo 

 bushels per acre. 



t The above fertilizers, previous to use, were mixed with live times their bulk of 

 meadow muck, and applied to the several lots in the hill.
