EXPERIMENTS IN MANURING. 
In view of the fact that France obtains fifty per cent. more wheat per acre © 
than the United States, and England more than a hundred per cent. greater 
crops, it is time that facts concerning fertilizers and improved modes of culture 
should be more carefully noted and better heeded. 
Mr. J. B. Lawes, who has been making wheat experiments in England for 
twenty-three successive years upon the same land, reports the result in the year 
just closed, with comparisons with three preceding years, and the average for 
fourteen’ years, as follows:

Mr. Lawes says: “From the progressive decline in the produce from year to 
year since 1863, it will, perhaps, be supposed that the result is in great meas- 
ure connected with a gradually declining condition of the land, and therefore 
not mainly the effect and the indication of variation in the productive character 
of the seasons. That the results are not due to the changing condition of the 
land, but to the changing character of the seasons is, however, evident. from 
the fact that several times during the last fourteen years the crops on these 
same plots have been as bad as, or worse than, in the present season ” 
The following statement shows the result in the most unfavorable seasons, | 
the worst being in 1853 : .

«The variation in amount of produce from year to year may, therefore, safely 
_be taken as almost wholly referable to season. The quality of the grain, as 
shown by the weight per bushel, is seen to be considerably above the average 
of the last fourteen years. y «
