[6.] Air is of course the object, not the subject of the verb.
[7.] Save where the beetle, etc. Cf. Collins, Ode to Evening:
| "Now air is hush'd, save where the weak-eyed bat With short shrill shriek flits by on leathern wing, Or where the beetle winds His small but sullen horn, As oft he rises 'midst the twilight path, Against the pilgrim borne in heedless hum." |
and Macbeth, iii. 2:
|
"Ere the bat hath flown His cloister'd flight; ere to black Hecate's summons The shard-borne beetle, with his drowsy hums, Hath rung night's yawning peal," etc. |
[10.] The moping owl. Mitford quotes Ovid, Met. v. 550: "Ignavus bubo, dirum mortalibus omen;" Thomson, Winter, 114:
| "Assiduous in his bower the wailing owl Plies his sad song;" |
and Mallet, Excursion:
"the wailing owl
Screams solitary to the mournful moon."
