The seed, “ Square Head’s Master,” was drilled on October 
20, 1906, at the rate of 9 pecks per acre, after being dressed 
with sulphate of copper. Mineral manures (3 cwt. superphos- 
phate and \ cwt. sulphate of potash per acre, in accordance 
with the new plan) were applied on December 10 ; rape dust 
(about 3| cwt. per acre) on March 7, 1907, and the nitrogenous 
top-dressings of sulphate of ammonia and nitrate of soda 
between April 13 and May 7. The heavier dressings (plots 
8a, 8aa, 9a) were put on in two lots (April 13 and May 7), the 
lighter ones on April 29. 
During the winter a distinct improvement was made in 
these experiments by the enclosure with wire fencing of 
the entire area devoted to the continuous growth of wheat 
and barley. For some time past it had been noticed that 
damage was being done to certain plots by hares and rabbits, 
and as the area comprised plots the largest of which was only 
J acre in extent, any accidental loss came to be more con- 
siderable when multiplied up to give the produce of a full 
acre. The wiring-in of these small plots thus tends to remove 
more effectually any sources of error. 
The season, it will be well remembered, was one marked by 
an almost entire absence of warmth, this causing a late and 
prolonged harvest. It was not until about August 15 that the 
plots began to ripen, and no cutting was done until August 27. 
Even then the weather was very “ catchy,” and the crops 
could only be got in with difficulty. Finally, all were carted 
by September 11. The plots to which lime had been applied 
presented, throughout the year, very striking appearances, and 
were the subject of much interest to visitors to the farm. 
Continuous rain during the month of November delayed 
threshing beyond the usual time, and it was not until 
December 3 that this could be undertaken. The corn was 
subsequently weighed and valued. The results are set out in 
Table I., page 246. 
The general produce was above the avei-age of the last ten 
years and rather better than in 1906, the unmanured yield 
(plot 7) being 12j bushels per acre. Plots 1 and 4, as explained 
previously, are influenced by trees and cannot be taken fully 
into account. 
Nitrate of soda alone, at the rate of just over 1 cwt. per 
acre, gave an increase of 5 bushels (3b) which was Dn-ther 
increased by 8 bushels (3a) when the quantity of nitrate was
