_Cult. Maples are for the most part trees of considerable 
size and beauty, and are chiefly used for plantations or avenues 
or the backs of shrubberies. Most of them will grow. from 
cuttings, which should be taken off at a joint, and planted in a 
sheltered situation in the open air, the earlier in autumn this is 
done the better, particularly if the weather be moist ; Mr. Sweet 
recommends the cuttings of most hardy trees and shrubs to be 
planted about the same time, as they succeed much better than 
if they are planted in spring, the usual time; the ground should 
Well fastened about them, so that the worms and frost may* ` 
not loosen them. They may be also increased by layers put 
own in the autumn. The seeds of this genus should be 
‘own if possible soon after they are gathered from the tree, 
“cause if sown then they will vegetate next spring, but if kept 
till spring few of them will vegetate the first year; these should 
e sown in a bed prepared for the purpose, and they should be 
Covered over about an inch thick of mould ; this bed should be 
tessed in spring before the plants make their appearance, and 
when the trees are of a sufficient size, which is generally after a 
year's growth, they should be planted out in rows, there they 
May remain until they are of sufficient size to be planted out 
mto plantations or shrubberies.

Cult. These trees are well adapted for the backs of shrub- 
beries. Cuttings taken off at a joint, and planted in a sheltered 
situation early in autumn will strike root. They may be also 
increased by layers put down at the same time, or by seeds.
