OF CLEANING, ETC. 
If any of the plants require cleaning, either by fumigation 
or otherwise, let it be done before the young foliage appears, 
according to the directions heretofore given. Likewise tie 
neatly all that require it, clean and top-dress those that will 
not be shifted, having every plant, and all in the green- 
house, in perfect order before the throng of spring com- 
mences. The weather will now admit, in very fine mornings, 
of the plants being syringed, which may be done between 
seven and eight o'clock ; and the path or pavement should 
be washed out once a-week, which is a great improvement to 
the appearance of the whole interior. 
In winter, when any glass is broken it should be imme- 
diately mended. Broken glass in cold nights causes a very 
destructive current of air. It should always be made water- 
tight, for if the drops fall into the pots upon the roots, they 
will frequently prove fatal to the plants; therefore care ought 
to be taken during rain to remove those that stand in any 
manner exposed. 
MARCH. 
The plants in this compartment will begin to assume a 
different aspect, and air must be admitted every day if practi- 
cable, giving large portions in sunshine by the sashes regu- 
larly over all the house, opening those of the front a little, 
and likewise the doors in fine mild days. To perform this 
judiciously, give a little about eight or nine o'clock, more at 
ten, and the whole from eleven till twelve o'clock, shutting 
again by degrees. 
Eire heat will now be dispensed with, but in frosty nights 
have the shutters on about sundown. The sun is now power- 
ful, and the house can be early shut up in the afternoon, and 
will gain as much natural heat as will keep up the required 
temperature, viz., 36° to 45°. Perhaps there may be un-
