Laudator Temporis Acti

William Cowper, The Task, Book I (The Sofa), lines 300-320:

Nor less attractive is the woodland scene
Diversified with trees of every growth,
Alike yet various. Here the gray smooth trunks
Of ash, or lime, or beech, distinctly shine,
Within the twilight of their distant shades;
There, lost behind a rising ground, the wood
Seems sunk, and shortened to its topmost boughs.
No tree in all the grove but has its charms,
Though each its hue peculiar; paler some,
And of a wannish gray; the willow such,
And poplar that with silver lines his leaf,
And ash far-stretching his umbrageous arm;
Of deeper green the elm; and deeper still,
Lord of the woods, the long-surviving oak.
Some glossy-leaved and shining in the sun,
The maple, and the beech of oily nuts
Prolific, and the lime at dewy eve
Diffusing odours; nor unnoted pass
The sycamore, capricious in attire,
Now green, now tawny, and ere autumn yet
Have changed the woods, in scarlet honours bright.
