Report on Prevention a,nd Cure of Potato Disease.” 767 
and entirely absent in the case of the “ Magnum.” No lessening of 
disease occurred in the case of the “ Myatt’s,” but a slight increase of 
crop (which just covered the cost of application) was obtainable from 
both early and late dressings. With the “ Snowdrop,” an early appli- 
cation reduced disease from 9'4 per cent, to ^ per cent, and largely 
increased the crop. The later application, though not so successful 
either in lessening disease or in increasing the crop, still paid 
well for using it. 
In the case of the “ Magnum,” as there was no disease to check, 
the crop-increases alone need be taken, the early application largely 
augmenting the yield, and the later one less so, but still remunera- 
tively. The large amount of dressing required on the B plots is 
noticeable, the tops having been very large. These results show that 
both early and late applications pay well, increasing the crop and 
reducing disease, the earlier dressing being the better in both 
respects.
