272 THE NURSERY. [March. 
rows, four feet distant, and plant from plant one foot in the row. 
Having two or three year's growth in these rows, they plant- 
ed successfully in any warm and tolerably rich sandy ground. They 
may also be propagated by suckers, which they throw up abundantly; 
especially, if some of their wide extending roots be cut through with 
an axe, &c. 
The Robinia glutinosa, is a charming plant; it produces in May nu- 
merous bunches of delightful flowers, grows to a good size, and is a 
gi'eat ornament in pleasure grounds. It may be propagated by seeds 
in like manner, or by grafting it on the former. 
The Robinia hisfiida^ or Rose Acacia, is a most beautiful flower- 
ing shrub, of humble growth, and may be propagated by suckers, 
which it produces in great numbers, or by grafting it on either of 
the above species. 
The. Ash, Lime, and Sour- Gum. 
The various kinds of Fraxinus or ash, are propagated by seeds, 
which are to be prepared in the same manner as directed for haws, 
in page 152, &c. for they do not vegetate till the second spring after 
the seeds are ripe. All the kinds take freely by grafting on one 
another. 
The Tilia americana, or American lime or Linden tree, together 
with every other species of the same genus, is easily propagated by 
layers, or by sowing the seeds in October or November, or in March, 
if preserved in dry sand till that time. Sow the seeds on an even sur- 
face, clap them in, with the back of a spade, and cover them a little 
better than half an inch deep. 
The Nyssa integrijblia, or Upland Tupelo-tree, or Sour-Gum, is 
propagated by seed, suckers, layers or cuttings; if by seed, sow 
them immediately when ripe, covering them an inch deep; some of 
them will come up the spring following, but many not till the se- 
cond year. The better way would be, to prepare them as directed for 
haws, and in the ensuing March examine them; if you then find ma- 
ny showing symptoms of vegetation, sow them; if not, let them re- 
main till that time twelve months. 
Deciduous Cypress, White Cedar, and Arbor Vitce. 
The Cufiressus disticha, bald or deciduous cypress, grows to an 
enormous large size, the foliage of which is uncommonly beautiful 
during the summer months. It is propagated by sowing the seed in 
March, in beds of good mellow earth, covering them half an inch 
deep; they must be kept very free from weeds, and when two years 
old, transplant them from the seed-beds into nursery rows. 
The Cufiressus Thyoides, or White Cedar, is propagated by sow- 
ing the seeds, which are very thin and flat, when taken out of the 
cones, in boxes of light earth, taken from swampy ground, and 
covered about the eighth of an inch, or a little better, with loose 
rich mould sifted evenly over them; they must have frequent 
sprinklings of water, and when up, and that the heat increases, the
