quality and value of the grain. The truth is, that there is very 
much more difference in the quality of grain grown by the same 
manure in different seasons, than by all the variety of manures used 
in the experimental plots, in the same season. In fact, excluding 
Nos. 14 to 18, the differences in weight per bushel and in value are, in 
all other cases, explained by comparatively slight differences in 
condition, dependent on the adaptation of the climatic conditions 
during the ripening and harvest periods to the slightly varying 
stage of growth and maturity at the time, under the influence of 
the very various manuring." 
By taking the mean value of the wheat produced on the two 
half-plots which have the same manures, and arranging the whole 
plots in the order of the market A^alue of their produce, we get the 
results shown in Table II., page 435. 
In the year 1889, the top half of each plot was sown with only 
half the usual number of rows of wheat, the full number being 
sown in the bottom half. On the top half the rows were 15 inches 
apart or 9 to the land, and in the bottom half they were 1\ inches
