254 The Woburn Field Experiments, 1907. 
It will be seen that the crop was an exceptionally heavy 
one, the lowest yield (plot 2) being over 50 bushels per acre, 
and the highest (plots 1 and 3) 54^ bushels. When such crops 
as these are yielded it is clear that the land was doing its 
utmost under the influence of the specially favourable season, 
and under such circumstances it was not to be expected that 
the manurial differences would tell. The heavy crop was, in 
fact, the result of “ season ” rather than of manuring. The 
crop of plot 1 (decorticated cotton cake) looked decidedly the 
heaviest, and it produced most straw, but it “ went down ” a 
good deal more than the others, and the yield was not more 
than from plot 3. The quality of the corn was not good, and 
none of the samples were really “ malting ” ones. 
Rotation IV. 1907, Wheat. 
This followed the green crop (mustard) of 1906. Nine 
pecks per acre of “ Square Head’s Master ” wheat were drilled 
on October 18, 1906, and a very nice crop was grown which 
seemed to show little difference between the four plots. It 
was cut on August 23, and later on was threshed and weighed, 
the results being given in Table VI.

Here, again, but little difference was shown between the 
several plots, either in corn or in straw. The yield of plot 1 
(decorticated cotton cake) was slightly the highest, but this 
was probably accidental. The wheats were described as “four 
very nice samples of wheat, being well grown, strong, and good 
Millers’ wheats.” 
As the new plan of experiment only began in 1904, and 
only Rotation IV. has as yet concluded its first rotation-course, 
it will be well to defer making a general summary of the 
conclusions come to until the other Rotations (I., II., and III.) 
have completed their course.
