pare water, as he recommends, would then have 
been of some use after the insects had been de- 
stroyed. “ This,” meaning the Honey Dew, “ is 
generally known, being a clammy substance which 
coagidates upon the leaves and wood of trees. It 
so much affects them sometimes, as to close up 
not only the poi’es of the leaves, but the wood 
also ill a great measure. A speedy removal is 
highly necessary, as the growth of the tree is 
frequently stopped by it. This may be done by 
frequently washing with pure water.” Many 
other similar accounts might be enumerated, but 
those are sufficient to show the existence of this 
erroneous opinion. If those of our friends who 
still waver in their opinion respecting the cause 
of this clammy substance, will take the trouble to 
examine the underside of the leaves and the ends 
of the young shoots which are hanging imme- 
diately over those shining leaves, they will be 
sure to find one or other species of the Aphides 
there residing j while those parts of the tiee oi 
plant where those insects do not exist, will be 
quite free from Honey Dew. To prove it is not 
produced from the atmosphere, we need only con- 
sider for a moment that were the Honey Dew to 
fall from the heavens, it would be impossible for 
one part of the tree to escape the fluid and the 
other part to retain it, or for one kind of tree 
to be completely covered with it, while trees of 
another kind shall be closely connected, and yet 
cpiite free. The sycamore, the gooseberry and
