acorns not more than three-quarters, or at most, an inch deep, with 

 light loose mould. 



The whole of the above kinds may remain in these seed drills for 

 two years, keeping them at all times very free from weeds; and as 

 they are generally, but more particularly the walnut kinds, subject 

 to push down long tap-roots, and not to form many lateral ones, it 

 will be proper, nay it will be necessary, in order to insure success 

 in transplanting, when they have had one or twp years' growth, to 

 open, in the spring, a small trench close to each row, and then with 

 a very sharp spade to cut the descending roots about six or eight 

 inches under ground, casting back the earth when done. This 

 will cause them to throw out a number of laterals, and the spring 

 following you can transplant them with safety into nursery rows, 

 at greater distances, to remain till wanted to plant out where final- 

 ly intended. 



Robinia, or Locust Tree. 



The Robinia pseudo-acacia, or common locust-tree, is said to be 

 superior to any other kind of wood for ship tunnels, mill cogs, and 

 fence posts, as well as for various other purposes. Its culture is 

 very easy, as it maybe propagated in great abundance by collecting 

 the seeds in autumn when ripe, preserving them dry till March, 

 then sowing them in a bed of good sandy loam, which is their 

 favourite soil, 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 what- 

 ever; sow them as above directed, and a good crop is certain. 

 When a year old transplant 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 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 

 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 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. 



Tlie 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 151, &c. for they do not vegetate till the second spring after
