REMEDIES FOR MILDEW.

according to the supply required; and at the end of every fortnight, 
other two might be covered, until the whole were done. The first 
rows will be ready for use towards Christmas, and the succeeding 
ones would continue until Asparagus was ready in the open ground. 
I recommend sowing about every third or fourth year, and destroy¬ 
ing the old plants; for although they would possibly continue bear¬ 
ing for twenty years, the produce of the young plants is so very 
superior, that it will scarcely bear a comparison with that of the old.

REMEDIES FOR MILDEW ON FRUIT TREES. 
BY MR. W. TOWN SEND. 
Of all the diseases to which trees are subject, I know of no one so 
rapid in its progress, or so fatal in its effects, as the mildew. So 
soon as it appears on the tree, vegetation ceases, and in a few days it 
is wholly covered, if its progress be not stopped. Men of science are 
but little acquainted with the nature or cause of this disease, and still 
less with a proper remedy. It is undoubtedly a species of fungus. 
Rather than notice the varying, and in many instances, contradictory 
opinions of writers on this subject, I will state the result of several 
experiments made with a view of finding some economical preventive 
for this disease. In the spring of last year, I washed part of my 
trees with lime water, thinking that if the disease were caused by in¬ 
sects, it would be the means of destroying them. Such was not the 
case, however, for it again made its appearance upon them, as well 
as upon those that were not washed. The lime and water being 
again employed with considerable force against the trees for a few 
successive evenings, when the disease first made its appearance, it 
was entirely eradicated ; consequently I came to the conclusion that 
washing the trees, when in a dormant state, is of no utility in de¬ 
stroying the mildew. 
Mr. Harrison recommends that the following ingredients be applied 
just before the bloom expands. Having first sprinkled the tree with 
water, it should be dusted over (particularly the young shoots) 
with common sulphur, mixed with a little Scotch snuff and tobacco 
dust. This was found an effective remedy, when applied on the first 
appearance of the disease, but when applied to trees in a healthful 
state, it apparently had no effect, for the mildew appeared on the 
young shoots a few days after its application. It is evident, there¬ 
fore, there is no preventive yet discovered.
