1)When passing through the woods, we must pause to see the squirrels busy (in?) hiding their nuts in the grass

2) "No time to turn at Beauty's glance, and watch her feet, how they can dance (Is the rephrase correct? We have no time to see the beautiful glance of a maiden and admire the skill of her dancing feet)
3) "No time to wait till her mouth can enrich that smile her eyes began" (How would you rephrase it? We should not miss the beautiful smile playing at her face??)
3)Can you help me rephrase this poem:
"Something removed roars in the ears of this house, hangs its drapes wingless, stuns mirrors till reflections lack substance. Some sound like the gnashing of windmills ground to a dead halt; a deafening absence, a blow." Something removed makes a deep, very loud noise in the ears of this house?? (personification)....
Thanks

1. "in" not needed.

2. That is an interpretation

3. We don't have time to wait for the smile in her eyes to become a smile on her mouth.

When a death occurs, everything associated with that person makes an impact. The author is saying that a death of someone living in a house would make the house itself grieve.
