Plot A, early opplication ; B, late application ; C, untreated. 
“ Snowdrop .” — Early applications lessened disease from 30 per 
cent, to 3'5 and 7'5 per cent., a largely increased crop also resulting. 
The advantage was with the double dressing. Late dressing also 
increased the crop, paying for the application, and it lowered disease 
from 30 per cent, to 14 per cent. 
“ Magnum .” — This crop had very little disease, and, on the 
plot dressed twice before disease came, there was entire absence of 
disease. There was some gain of crop, more than enough to pay the 
cost of application from the early dressings, the double dressing 
being the better. A small decrease of crop resulted from late 
application. Owing to the small extent to which disease prevailed, 
the influence of the dressing on prevention of disease is not marked. 
The general result of Mr. Scott’s experiments is to show a 
marked lessening of disease and also increase of crop from dressing 
the plots early, a double dressing before disease appeared being, on 
the whole, the best. The late applications had a less marked effect, 
though in the same direction, and there was only one case of loss 
through the applications, and that a very slight one. 
2. Bedford. Messrs. Malden Brothers' Farm . — There was not 
much disease here. The crops were weighed September 21 (“ White 
Elephant ”) and November 8 (“ Imperator”). With the “White 
Elephant,” an early dressing reduced disease from 5'5 per cent, to 
•05 per cent, and gave also a paying increase of crop. A still larger 
gain of crop was obtained by the later dressing, but there was more
