THE MASSACHUSETTS SOCIETY FOR PROMOTING AGRICULTURE, 



Offers the following premiums for Experiments with Manures, and 

 competitors for the preceding can also compete for this, with the 

 same experiments : — 



1st premium, $100 ; 2d do., $100 ; 3d do., $100. 



A similar report of all the above items, except the nature of 

 the soil, will be required in 1864, and in 1865, when the premiums 

 will be awarded. No manure is to be apphed to the second and 

 third crop. 



The above premiums are open to competitors throughout the 

 Commonwealth. Competitors for premiums offered by other Agri- 

 cultural Societies are invited also to compete for the above, the 

 same experiments serving for both, by filing a duplicate statement 

 with the Secretary of this Society. 



In awarding the premiums, all other things being equal, prefer- 

 ence will be given to those which are tried on the largest space of 

 land, and also where the competitor weighs the whole crop instead 

 of an average rod. Notice of an intention to compete must be 

 given to the Secretary on or before the first day of January, 1864, 

 with the statement required in the terms of the premium. 



This offer of premiums for experiments on the application of 

 manures is distinct from those on the same subject offered by the 

 same Society, February 18th, 1861, and January 14, 1862, and 

 requires a different series of experiments. 



P. C. Brooks, Jr., Secretary. 



Boston, Feb. 1, 1863.

 ed, the other half ploughed in the usual manner, — statements of 

 the depth of ploughing, in each instance, together with all the 

 particulars of culture, required, $8 ; second best, 



COMPARATIVE VALUE OF CROPS AS FOOD FOR

 kinds of fodder used, with a statement in detail of the quantity 

 and value of the same, as compared with English hay, the ex-
