FIELD EXPERIMENTS. 
Continuous Growing of Wheat {Stackyard Field ), 
1905 (29th Season). 
The land, after being cultivated, ploughed, and cleaned, was 
drilled on October 14, 1904, with “ Square Head’s Master ” 
wheat at the rate of 9 pecks per acre. The soil was in capital 
condition and the seed went in well. Mild weather following, 
the wheat began to show on October 28. A week later it was 
well np on most of the plots, but already the failure of plots 2a, 
5, and 8 (on which ammonia salts had been continuously 
used) was marked. On the contrary, plot 2b, to which lime 
in addition had been given in December, 1897, showed 
up favourably. Owing to windy weather the application 
of mineral manures was delayed until November 5. 
The application of lime to plot 2b of the continuous wheat 
series, as also in the case of plots 2b, 5b, 8aa, and 8bb of the 
continuous barley series, having produced such striking results, 
it was decided, now that the other plots (5 and 8, on which 
ammonia salts had been used) had begun to show failure of 
crop, to extend the experiment with liming. On plot 2b, lime 
had been put on in December, 1897, at the rate of 2 tons per
