or big together, and transplant them out, placing the larger ones together in rows, and the smaller 
by themselves. 
The rows should be three feet asunder, and the plants a foot and a half distance in the rows; in 
this nursery they may remain two years, by which time they will be strong enough to plant where 
they are to remain; for the younger they are planted out, the larger they will grow; so that where 
they are designed to grow large, they should be planted very young; and the ground where the plants 
are raised, should not be better than where they are designed to grow; for when the plants are raised 
in good land, and afterwards transplanted into worse, they very rarely thrive; so that it is much the 
best method to make the nursery upon a part of the same land, where the trees are designed to be 
planted, and then a sufficient number of trees may be left standing upon the ground, and these will 
outstrip those which are removed, and will grow to a larger size. 
Where people live in the neighbourhood of Ash-trees, they may supply themselves with plenty 
of self-sown plants, provided cattle are not suffered to graze on the land, for they will eat off the 
young plants, and not suffer them to grow; but where the seeds fall in hedges, or where they are 
protected by bushes, the plants will come up and thrive. 
Species 2, &c. The other sorts are commonly propagated in the nurseries by budding or ingraft¬ 
ing upon the common Ash ; but are not so valuable as those which are raised from seeds, because the 
stock grows much faster than the grafts ; so that the lower part of the trunk, so far as the stock rises, 
will often be twice the size of the upper; and if the trees stand much exposed to the wind, the grafts 
are frequently broken off from the stock, after they are grown to a large size. 
Fraxinus Ornus is generally planted for ornament, the flowers making a fine appearance when 
they are in beauty, for almost every branch is terminated by a large loose panicle; so that when the 
trees are large, and covered with flowers, they are distinguishable at a great distance. 
All the other sorts serve to make a variety in plantations, but have little beauty to recommend 
them; and as their wood seems to be greatly inferior to that of the common Ash, there should be 
few of these planted, because they will only fill up the space where better trees might grow’. 
Genus 20. Gleditsia. Acacia . Class XXIII. Polygamia. 
Order II. Dioecia. 
This tree is common in most parts of North America, where it is known by the name of Honey 
Locust; it is called by the gardeners here Three-thorned Acacia. It rises with an erect trunk to the 
height of thirty or forty feet, and is armed with long spines, three or four inches long, which have 
two or three smaller ones coming out from the side, and are frequently produced in clusters at the 
knots of the stem. Leaves bipinnate, composed of ten pairs of leaflets, of a lucid green and sessile. 
The flowers come out from the side of the young branches, and being of an herbaceous colour, make 
no figure. Legume near a foot and half long, and two inches broad. Seeds smooth, surrounded by 
a sweet pulp. 
The leaves seldom come out till June in this country, and the flowers not till the end of July, 
This tree does not produce any flowers till it is of a large size. There was one in the Bishop of 
London’s garden at Fulham, which produced pods in the year 1728 , that came to their full size, but 
the seeds did not ripen. 
It appears from Plukenet that it was cultivated by Bishop Compton in 1700 .*
