EFFECTS WITH PUTRESCENT MANURE.

hot from its fermentation when carrying to the field. It was then 

 about half rotted. The rate at which it was applied was about 

 807 heaped bushels to the acre, which was too heavy for the best 

 nett profit. The corn on the oldest marling (B) showed scarcely a 

 trace of remaining damage, while that on I) 2 (not manured) was 

 again much injured. On the manured part, D 1, and C, the 

 symptoms of disease began also to show early; but were so soon 

 checked by the operation of the putrescent manure, that very little 

 (if any) loss could have been sustained from that cause. The 

 following table exhibits all the measured products for comparison : 



The products of the spaces A and B, in 1828, were not only 

 estimated as usual from the measurement of the corn in ears (which 

 estimated quantities are those in the table), but they were also 

 shelled on the day when gathered, and the grain then measured, 

 and again some months after, when it had become thoroughly dry. 

 Care was taken that there should be no waste of the corn, or other 

 cause of inaccuracy. The result showed nearly double the loss 

 from shrinking in the corn not marled, and of course a proportional 

 greater comparative increase of product in that marled, besides the 

 increase which appears from the early measurement exhibited in 

 the table. The grain of A, not marled, when first shelled, mea- 

 sured a very little more than the quantity fixed by estimate made 

 as usual by measurement of the ears, and lost by shrinking 30 per 

 cent. The marled grain, from B, measured at first above 4 per 

 cent, more than the estimate, and after shrinking, fell below it so 

 much as to show the loss to be 16 per cent. The loss from shrink- 

 ing in this case was greater than usual in both, from the ..poverty 

 and consequent backwardness of the part not marled, and the un- 

 commonly large proportion of replanted and of course late corn on 

 the whole.
