There, under the shadow of the elm trees which Bacon had planted, Pepys and his wife constantly walked.
The chief trees of the country are the aspen (Populus tremuloides), the ash-leaved maple (Negundo aceroides), oak (Quercus alba), elm (Ulmus Americana), and many varieties of willow.
The elm is also scarce.
The oak, elm, hazel, ash, apple, lime and maple disappear to the east of the Urals, but reappear in new varieties on the eastern slope of the border-ridge of the great plateau.
In the rest of Italy the elm and the maple are the trees mainly employed as supports.
