the plots. Hoeing began on March 14th, and was finished the 
first time on the 24th. On the 27th, the nitrogenous top- 
dressing's of ammonia-salts and nitrate of soda were sown on 
plots 2, 3, 5, 6, 8 A and 9 A, these being, as usual, sown by a 
broadcast manure distributor, after being mixed with three 
times their bulk of dry sand. At that time, plots 2 and 3 
looked decidedly the thinnest in the field, thinner even than 
plot 1 (no manure). Plot 7 (unmanured for the 9th successive 
year) looked very well. Plots 2 and 3 looked rather frost-bitten. 
Early in April the land was again hoed, and then cross-hoed. 
The plots that had nitrogenous manures soon appeared of a 
much darker colour than those with mineral manures only. 
Fine warm weather came in April, and the plants made rapid 
progress. Any gaps were now filled up by transplanting. By 
April 20th, the effects of the top-dressings on plots 8 A and 9 a 
were plainly visible, the latter seeming then to be the best plot 
on the field. The dung on 10 B and 11b also showed its efficacy 
as compared with the unmanured half-plots 10 A and 11a. 
Plots 2 and 3 at this stage did not look better than the un- 
manured plots 1 and 7, but 5 and 6 were both good. Cold and 
also wet weather followed and made it difficult to get rid of the 
weeds, but this was successfully done by the end of May. The 
wheat came into ear about June 20th. In the later period, plots 
2 and 3, which had been rather backward, came on well. Plots 
8 A and 9 A, especially the latter, promised to be very heavy 
crops, while 5 and 6 were also capital. By the beginning of 
August nearly all the plots were quickly getting ready. A 
storm on the night of August 4-5, caused some of the wheat,, 
notably on plot 9 A, to go down somewhat. On August 20th and 
21st, the crop was cut, tied, and stacked. The produce was- 
threshed in the field on October 21st, the straw weighed at once,^ 
and the grain stored in the granary, and weighed on Oct. 24th. 
The results are given in Table I. 
Speaking generally, the produce was lower than in 1884, and 
more like that of 1883. 
The unmanured plots, the ninth successive crop, gave 21*3 
and 21'9 bushels per acre, as against 23"1 and 26 G bushels 
last year. Mineral mixtures alone only increased the produce 
to 22 4 bushels. 200 lbs. ammonia-salts per acre, on the 
other hand, gave a yield of 31*2 bushels, and 275 lbs. nitrate 
of soda of 28" 1 bushels, the increase in either case being com- 
paratively less than last year, ammonia-salts, as then, giving the 
higher yield. Minerals with 200 lbs. ammonia-salts per acre 
produced 37-5 bushels ; and minerals with 275 lbs. nitrate of 
soda per acre 38"9 bushels, the nitrate having a slight advan- 
tage. With double the quantities of ammonia-salts and nitrate
