roller. 
Gravel Walks. 
Now is the time to begin to turn gravel walks where the surface 
is dirty, &c., especially in the middle states, observing, that this is 
to be done where necessary in all parts of the Union as early as 
possible in spring. 
The gravel walks which display a dirty surface, or are annoyed 
with weeds, should be turned as early in this month as the weather 
gets dry and comfortable, in order to render them neat and conve- 
nient for walking on. For the method of doing which, as well as 
that of their general formation and treatment, see the Flower-gar- 
den for next month, to which I particularly refer you, and advise 
as much of that work to be done in this as the weather and hurry 
of businesg will permit. 
Such gravel walks as were broken up and laid in ridges the be- 
ginning of winter, which is a very bad practice as noticed in page 
77, should now be levelled down, formed, dressed, and rolled, as 
directed next month. 
The necessity of due attention being paid to all your walks, on 
the opening of spring, is so evident, that it is scarcely necessaV-y to 
urge it; the having them neat and newly dressed will give a gay 
and sprightly appearance to the whole garden. 
THE GREEN-HOUSE. 
The green-house plants should now have plenty of air admitted 
to them at all favourable opportunities, particularly as the weather 
gets warm towards the latter end of the month, but due attention 
must be paid, in any sudden changes, which are very frequent at 
this season, to preserve them from cold, cutting, or frosty winds; 
during the prevalence of which, the windows, &c. should be kept 
close, for such weather would ruin some of the tender kinds, and 
would be of bad consequence to all. It need hardly be said that 
the windows and doors must be kept close every night, and should 
imperious necessity require it, in the early part of the month, the 
flues heated at night to counteract the power of severe frosts. 
Look over the tubs or pots every other day, and see where water 
is wanting, and let such as require it be supllied therewith, taking 
care to use moderation in that case. Water will be serviceable to 
most of the plants, but especially to all the woody kinds, which will 
now require more frequent refreshments, if fine mild weather, but 
always in moderate quantities; and be still careful, on the whole, not 
to give too much water at a time, for that would prove the destruc- 
tion of many kinds, and would be prejudicial to the plants in gene-
