832 Report on the Experiments with " Bo^(illie Bordelaue:' 
while in plot A there were only ^ per cent., but in plot B the proportion 
rose to 5^ per cent. Further and more decided experiments are, 
however, needed before trustv/ortby conclusions can be arrived at 
as to the influence of the mixture on the fungus causing the disease. 
It is, further, obvious from the table that the use of the mixture 
has secured a larger crop. In each case, except Cheshire, there is 
a distinct advantage, and in most of the plots a considerable gain 
stands to the credit of the mixture. 
The plots at Carmarthen were not attacked by the fungus caus- 
ing the potato disease, but an obscure malady, locally called " sea. 
blight," made its appearance suddenly. A small black spot showed 
itself on the leaf, which rapidly spread, until in a fortnight every 
leaf was dried up and dead. The dressing had a beneficial effect, 
which showed itself in the dressed plot keeping green for some 
weeks after the foliage of the potatoes in the rest of the field had 
been destroyed.

The dressing had a marked effect in this single experiment, no 
doubt due to what Mr. Riley observed, the continuance of the plants 
in active life for weeks after the untreated plants were all dead.
