CALCAREOUS MANURES— PRACTICE. §7 



it formed a beautiful green though low cover to even the poorest of the 

 marled land. Marked spots, which were so diseased by over-marling as 

 not to produce a grain of corn or wheat, produced clover at least as good 

 as other places not injured by that cause. The square, which had been 

 sown in the same manner, and on which the plants came up well, had 

 no clover remaining by April, 1826, except on a few small spots, all of which 

 together would not have made three feet square. The piece not marled, 

 white with poverty grass, might be seen, and its outlines traced, at some 

 distance, by its strong contrast with the surrounding dark weeds in winter, 

 or the verdant turf of white clover the spring before. 



1827. Still at rest. No grazing allowed on the white clover. 



1828. In corn— the land broken in January, five inches deep. October 

 14th, made the following measurements: 



In the square not marled, (A) 105 by 104i feet (thirty-six square yards 

 more than a quarter of an acre,) made one barrel of ears — 



Bushels, pecks.

Gain, 1^ 



New marling, 105 by 104^ feet, on the side that seemed to be the most 

 diseased, (D) 1^ barrels — or nearly 12 bushels to the acre. 



1832. Again in corn. Since 1826, the mild four-shift rotation had been 

 regularly adhered to. Ploughed early in winter five inches deep, and again 

 with two-horse ploughs just before planting, and after manuring the land 

 above the dotted line D x\ The manure was from the stable yard, the 

 vegetable part of it composed of straw, corn-stalks, corn-cobs, and leaves 

 raked from wood-land, had been heaped in a wet state a short time before, 

 and was still 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 net profit. 

 The corn on the oldest marling (B) showed scarcely a trace of remaining 

 damage, while that on D 2 (not manured) was again much injured. On the 

 manured part, D l,and C, the symptoms of disease began also to show 

 early — but were so soon checked by the operation of the putrescent ma- 

 nure, that very little (if any) loss could have been sustained from that cause.
