- fruit. To make a further trial, a row of Seedling Industry was 
taken containing thirty-five plants, each alternate plant being 
sprayed, and, although the plants were very close together, the 
sprayed ones could be easily distinguished from either end. — 
Considering the cheapness of the remedy, the potassium sulphide 
in a cheap form costing about twenty-five cents per pound and 
one pound making thirty-two gallons of mixture, it would seem 
as if the culture of gooseberries might be made profitable again. 
A DISEASE OF THE HOLLYHOCK. 
In the latter part of May, there was found on the grounds of 
one of our leading nurserymen, hollyhocks infested with a disease 
new to this section. Samples were sent to Professor W. G. Far- 
low, Cambridge, Mass.; Professor W. R. Dudley, Cornell Uni- 
versity, and Professor C. H. Peck, Albany, N. Y., all of whom 
pronounced it the true hollyhock blight (Piccmia malvacearum). 
_ Professor Farlow records its appearance in this country in 1886, 
and its introduction traced to seeds impurted from Europe, in. 
which country it made its appearance between 1870 and 1875, and 
spread to such an extent that in many places the cultivation of 
the hollyhock was for a time abandoned. 
The seed from which the affected plants were grown in the 
aforesaid nurseries, was bought of a seed firm who, presumably, 
imported direct from some point in Europe. ‘The disease 
attacked the plants on the Station grounds that were grown from 
seed raised here, and as we are at least one-fourth of a mile from 
those in the nurseries, it is difficult to tell whence it came, unless 
the spores of the fungus were carried by the wind. ‘The only 
efficacious remedy known is the total destruction of the plant by 
burning. Professor Peck suggested the application of Bordeaux 
mixture or any of the fungicides used against grape fungi. There 
has been tried at the Station the mixture used for gooseberry 
- mildew, sulphide of potassium, and a solution of one-fourth of a 
pound of salt to two gallons of water, but with no marked success. 
Tt is to be hoped that a remedy may be discovered for this 
disease, as the loss of this stately garden favorite would be felt 
the world over. :
