post at the approach of the reviving spring. 
The depredations the Aphides infecting the 
apple tree commit are sometimes extensive. Tlie 
leaves and young shoots they infest ai’e not con- 
sumed by them, but by perpetually pumping out 
the sap, the leaves and ends of the young shoots 
become so crippled and so much exliausted, that 
if they survive at all, their progress is prevented 
for that season. When apple ti’ees are much in- 
fested, their appearance becomes unsightly, and 
the fruit is small, ill-flavoured and so dirty with 
the fluid they eject, that it is almost useless. 
I would remark here, that this species, with 
most others of its genus, is the cause of that sac- 
charine substance which is so generally seen on 
the upper sm-face of the leaves of the trees and 
plants, and which is the cause of so many false 
notions respecting the Honey Fall, a name given no 
doubt on account of the sweetness of the fluid. 
Many preposterous ideas have long existed, and 
still exist, respecting it, not among the illiterate 
only, but even among the learned. Hence we 
find that Pjliny, the Roman Naturalist, has been 
at a loss for its real source. He says “ I am at a 
loss wkether 1 shall call it the sweet of the heavens, 
the saliva of the stars, or a liquid produced by the 
purgation of the air! ! !” and it is not uncommon 
for persons at this day to make similar remarks to 
those of Pliny. This was exemplified in my pre- 
sence very lately by an experienced Horticulturist,
