are formed. These ascospores germinate on the bushes 
the following spring, and give rise to the disease again. 
Now such a bad disease must be kept in check by 
all means possible, or the bushes may be practically 
ruined by it. The diseased parts may be dusted over 
with sulphur and quicklime, 2 parts of sulphur to 1 of 
lime. This is very effective, but it leaves the bushes 
rather unsightly, and for this reason is not so much used, 
especially where the bushes are grown in prominent posi- 
tions. The bushes affected may be sprayed with potassium 
sulphide, which does not make the foliage so unsightly, or 
they may be sprayed with Bordeaux mixture — the paste 
form being used — which does not leave a deposit on the 
leaves. If the bushes are badly attacked, the affected 
shoots and leaves may be cut off and burned before the 
winter ascospores are formed; this will keep the disease 
in check another season. 
If the season is favourable to the spread of this disease 
the bushes should be sprayed with Bordeaux mixture after 
the first crop of flowers is cut; this will keep the disease in 
check considerably in the autumn, the time most dreaded 
for this disease. 
HOLLYHOCK RUST 
This disease made such strides among the Hollyhocks 
that it was found almost impossible to grow these plants 
in some places. It is well known in appearance to all 
growers of these majestic plants. The leaves become 
yellow, and are soon covered at intervals with brown, 
hard, wart- like outgrowths. These spread to the stem,
