The juiceless foliage, and the tasteless fruit;
There she perceives them round the surface creep,
And while they meet their due distinction keep;
Mix'd but not blended; each its name retains,
And these are Nature's ever-during stains.
And wouldst thou, Artist! with thy tints and brush,
Form shades like these? Pretender, where thy blush?
In three short hours shall thy presuming hand
Th' effect of three slow centuries command?
Thou may'st thy various greens and grays contrive;
They are not Lichens, nor like ought alive;-
But yet proceed, and when thy tints are lost,
Fled in the shower, or crumbled by the frost;
When all thy work is done away as clean
As if thou never spread'st thy gray and green;
Then may'st thou see how Nature's work is done,
How slowly true she lays her colours on;
When her least speck upon the hardest flint
Has mark and form, and is a living tint;
And so embodied with the rock, that few
Can the small germ upon the substance view.
Seeds, to our eyes invisible, will find
On the rude rock the bed that fits their kind;
There, in the rugged soil, they safely dwell,
Till showers and snows the subtle atoms swell,
And spread th' enduring foliage;--then we trace
The freckled flower upon the flinty base;
These all increase, till in unnoticed years
The stony tower as gray with age appears;
With coats of vegetation, thinly spread,
