with the purchase, for this product Is
frequently adulterated. Note to, that
the sulphate Of copper cannot be dis
solved In any metal vessal copper ex-
cepted). and that great prudence should
be observed in handling 1t, as it is a
strong poison.
The application of the "bouillie Dor.
delaise" is effected by means of special
instruments, like hoses which have been
called pulverisers, and which, when they
work we'll, pour out the liquid in fine
rain As rule, "bouillie" can be applied
for the first time as soon as the leaves
are fOrmed-that is, when the plants be-
gin to flower; but great care must lie
taken that this treatment precedes the
appearance Of the parasite mushroom.
This, as it is known. usually appears
about the first fortnight in July. The
treatment, therefore, should be carried
out about the end OF June or the begin
ming Of July. However, as the efficacy
Of this treatment Is only of limited du.
ration, it should be applied a second
time few weeks later. As a rule. these
two applications are sufficient, but on
low, damp SOIL or during very rainy
season, or under any circumstances fav.
Orable to the spread of the disease, ii
would be advisable to repeat the treat
ment three times, and at shorter inter
walls. Late potatoes almost always need
three treatments, particularly If the
summer has been rainy.-English CORE
