MARCH] THE NURSERY. 283 



and covering them half an inch deep. They will come up in the 

 course of the following month numerously, for no seeds grow more 

 freely, notwithstanding what some unexperienced persons assert to 

 the contrary. They require no preparation whatever; sow them as 

 above directed, and a good crop is certain. When a year old trans- 

 plant them out of the seed-bed into nursery rows, four feet distant, 

 and, plant from plant, one foot in the row. Having two or three 

 years' growth in these rows they may be planted successfully in any 

 warm and tolerably rich sandy ground. They may also be propa- 

 gated 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 

 numerous bunches of delightful flowers, grows to a good size, and is 

 a great ornament in pleasure-grounds. It may be propagated by seed 

 in like manner, or by grafting it on the former. 



The Robinia hispida, or rose acacia, is a most beautiful flowering 

 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, 

 on page 160, &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 

 surface, clap them in with the back of a spade, and cover them a little 

 better than half an inch deep. 



The Nj/ssa integrifolia, 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 second year. 

 The better way would be to prepare them as directed for haws, and 

 in the ensuing March examine them; if you then find many show- 

 ing symptoms of vegetation, sow them; if not, let them remain till 

 that time twelve months. 



DECIDUOUS CYPRESS, WHITE CEDAR, AND ARBOR- VITJS. 



The Cupressus 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 Cupressus thyoides, or white cedar, is propagated by sowing
