Because the circumambient air throughout
With its first impulse circles still, unless
Aught interpose to cheek or thwart its course;
Upon the summit, which on every side
To visitation of th'           air
Is open, doth that motion strike, and makes
Beneath its sway th' umbrageous wood resound:
And in the shaken plant such power resides,
That it impregnates with its efficacy
The voyaging breeze, upon whose subtle plume
That wafted flies abroad; and th' other land
Receiving (as 't is worthy in itself,
Or in the clime, that warms it), doth conceive,
And from its womb produces many a tree
Of various virtue.
