syringe, such as the Abol Syringe, using the bend attached to get
at the under-side of the leaves where the fungus first appears, this
wash acts rapidly upon the pests.

_Mo-Effic_, a new preparation, has been highly recommended in the last
two years. I have not tested it myself. But Mr. Mawley considers it most
successful.

=Black Spot= is another troublesome pest. It attacks the foliage alone,
and not only spoils the appearance of the leaves, but so injures them
that they fall off prematurely. The disease can be best checked by
spraying with the _Liver of Sulphur_ wash, beginning early in the spring
and going on at intervals.

=Rose Rust= and =Rose Leaf Scorch= may also be combated with _Liver of
Sulphur_ wash.

But in all these three last diseases, it is a matter of the greatest
importance to collect the badly diseased leaves on the plant, and
especially to pick up every one lying on the ground, and to see that
they are burnt at once and not thrown on the rubbish heap, where they
will only infect the soil.

=Sooty Mould=, the unsightly black stuff which often covers the foliage,
is a parasitic fungus not upon the leaf itself but upon the "honey dew"
deposited by Green Fly. If therefore the honey dew is kept off by
destroying the Aphides which secrete it, _Sooty Mould_ will not appear.

INSECT PESTS.

=Green Fly=, or =Rose Aphis=, is alas! too well known in every garden to
need much description. But the reason why it is so difficult sometimes
to get rid of this pest is not so commonly known. The Aphides breathe
through pores at the sides of their bodies. And in order to kill them,
some substance must be used which will close these pores. Therefore
syringing with water or any clear liquid is absolutely useless; for if a
few Green Fly are knocked off one shoot they will only settle on some
other. We often hear people say after a thunderstorm, "This will clean
the roses and wash off the Green Fly nicely." Far from it. They only
increase the faster; while the caterpillars rejoice, and flaunt
themselves openly on every bush. Then in despair some one uses paraffin
or some violently caustic wash for spraying the Green Fly, and destroys
his roses thereby.

Nature has mercifully provided some enemies to prey on the Green
Fly--and these help in some small degree to keep the pest down. The
chief of these is the Ladybird, which both in its adult and in its
larval state devours them ceaselessly. The pretty green Lace-
