I do not know of any in Scotland, except a few hundreds which I raised from seed about ten years ago, and which are now planted out in mixture with the Japanese _Cercidiphyllum_. The only fault I find with them is that, while the young growth is as tender as that of the common walnut, it is earlier in starting, and therefore more liable to injury from spring frosts. The timber of the black walnut is quite equal in quality and superior in beauty to that of the European species. The tree is sometimes confused with the kindred genus hickory (_Carya_), whereof there are many fine specimens in Great Britain; but the two genera may be readily distinguished from each other by cutting across a twig. The pith of all species of walnut is neatly chambered, that of the hickories is solid.

This life is most jolly." It is rather curious that, dearly as Shakespeare loved the woodland and ready as he ever was to enrich his verse with references to trees and flowers, he never mentions the holly except in this song from _As You Like It_. This is the more remarkable because holly is more widely distributed over Britain than most other forest growths, and must have been far more abundant in the sixteenth century before the land was infested by rabbits to the extent it is now; for these accursed rodents make a clean sweep of holly seedlings and also destroy large trees by barking them. It may be thought that the holly should be ranked as a shrub rather than as a forest tree; but when well grown it is fairly entitled to the superior rank, for there are many fine specimens in these islands upwards of 50 feet high. Dr. Henry measured one in 1909 near Ampthill, in Bedfordshire, 60 feet high and ll½ feet in girth. But this tree has no single bole, for it divides into seven large stems at about 18 inches from the ground. A far more shapely specimen is one which Lord Kesteven measured at Doddington Hall, Lincoln, and found in 1907 to be about 50 feet high, with a girth of 9½ feet at breast height. Being very patient of shade, the holly is sometimes drawn up to still greater height than this; Mr. Elwes having found some at Russells, near Watford, crowded among beech trees and rising to 70 and 75 feet.
