planting. When they have been well hardened, and a judicious 
time selected for turning them out, they commence growing im- 
mediately ; whereas, if not well hardened, the leaves will turn 
entirely brown, and several weeks of the season will be lost be- 
fore they recover their vigour ; and perhaps then will not have 
sufficient time for flowering so well as they otherw ise would have 
done. Those who have the advantage of a spare wall, might 
also, with advantage, cover it with some of the more hardy of 
the hard-wooded New Holland plants, which seldom flower pro- 
fusely, until established for two or three years, receiving some 
slight protection in winter. These are more appropriate for 
w’alls, than such plants as will, in every season, flower well in the 
open ground. We will, shortly, give a list of shrubs which are 
suited to the purpose here suggested. 
191 M.vnure, the application of. The properties of various 
species of Manure, the comparative stimulus which they afford 
to different plants, and the best modes of applying them, are 
subjects of the first importance to the horticulturist. These con- 
siderations, hitherto much neglected, are now meeting due atten- 
tion from practical as well as theoretical men; and as general 
principles become estalilished, or particular facts of importance 
elucidated, we intend introducing them to our readers. Dr. 
Lindley, in his Theory of Horticulture, has some observations 
on the application of Manures, which are much to the purpose, 
and which we transcribe. They may be useful to be held in 
mind, w hen we, hereafter, treat on the preparation of stimulating 
substances. He says “ Provided manure is of a permanent char- 
acter, it does not very much matter at what time it is admin- 
istered, because, if it does not act at first, it will sooner or later; 
but when it is of such a nature as to he easily dissipated, like 
malt -dust, or soot, or yeast, a knowledge of the proper season 
becomes extremely necessary. Plants will not receive the influ- 
ence of manure so readily at any season as w hen they are in the 
most rapid and steady growth ; because at that time the absorb- 
ing force of their roots, and their vital energies are all greatest. 
It is for this reason that a top-dressing is almost useless to a 
lawn at midsummer, but better in the spring, and best of all in 
October. If applied at midsummer, the ground is dry, and the 
vegetation extremely languid. When a top-dressing is applied 
in the spring, the lawn profits by it so long as it continues to
