for the Growth of Undiscased Potatoes.

suffered more than the late varieties ; but when the crop was 
raised it was found that there was 21 per cent, of the early, 
and 27 per cent, of the late, diseased. At Mojnalty (Leinster) 
the potatoes were grown in lazy beds in a field which had been 
a neglected pasture for a great many years, and which was 
ill very bad condition. On August 18th all the sorts were 
attacked by disease, the early again showing a greater injury 
that the late varieties. The disease first appeared in the 
potatoes growing under some large trees which bordered the 
field ; at the time of my visit the foliage in these patches wAs 
quite blackened. When the crop Avas raised more than a fifth 
of the late varieties were diseased, and a smaller proportion of the 
early ones. The potatoes were in a very flourishing condition at 
Mullaghmore (Ulster), when I visited them on the 19tli August, 
but the disease had made its appearance some days before, and 
already it was visible on the foliage of all the plots as well as of 
the general crop. In the prosecution of my inspection I found 
the disease present in the plots at Longtown and Perth, and 
more extensively at Ayr. At Elgin some of the general crop 
was injured by the disease, but as I have alreadv stated I did 
not detect any trace of the disease at the stations in Northum- 
berland and East Lothian. 
The result of this visit to the various localities left no uncer- 
tainty as to the competition for the Society's prizes, but it was 
determined to carry out the programme fixed upon. 
The condition of the crops as affected by the disease at the 
time they were raised is exhibited in the annexed (V.) and 
following (VI.) Tables : —
