to keep the frost away from the
plants, as might be supposed, but rather to prevent the sun from getting
at the soil and thawing the frost that has taken possession of it.
Scientific investigation has proven that a plant, though comparatively
tender, is not seriously injured by freezing, if it can be _kept frozen_
until the frost is extracted from it _naturally_,--that is, gradually
and according to natural processes. It is the frequent alternation of
freezing and thawing that does the harm. Therefore, if you have a tender
Rose that you want to carry over winter in the open ground, give it
ample protection as soon as the frost has got at it--before it has a
chance to thaw out--and you can be reasonably sure of its coming through
in spring in good condition. What I mean by the term "ample protection"
is--a covering of one kind or another that will _shade_ the plant and
counteract the influence of the sun upon the frozen soil--not, as most
amateurs seem to think, for the purpose of keeping the soil warm. I have
already made mention of this scientific fact, and may do it again
because it is a matter little understood, but is one of the greatest
importance, hence my frequent reference to it.
If earth is used as a covering, it should be dry, and after it is put
on, boards, or something that will turn rain and water should be put
over it. Old oil-cloth is excellent for this purpose. Canvas that has
been given a coating of paint is good. Tarred sheathing-paper answers
the purpose very well. Almost anything will do that prevents the earth
from getting saturated with water, which, if allowed to stand among the
branches, will prove quite as harmful as exposure to the fluctuations of
winter weather. If leaves are used,--and these make an ideal covering if
you can get enough of them,--they can be kept in place by laying coarse
wire netting over them. Or evergreen branches can be used to keep the
wind from blowing them away. These branches alone will be sufficient
protection for the hardier kinds, such as Harrison's Yellow, Provence,
Cabbage, and the Mosses, anywhere south of New York. North of that
latitude I would not advise depending on so slight a protection.
Earth-covering is preferable for the northern section of the United
States.

canes are stiff and brittle. Their thorns are formidable. One person,
