Lines to a Persian Cat

The final lines are used as the title of Act 2.

The songsters of the air repair
To the green fields of Russell Square.
Beneath the trees there is no ease
For the dull brain, the sharp desires
And the quick eyes of Woolly Bear.
There is no relief but in grief.
O when will the creaking heart cease?
When will the broken chair give ease?
Why will the summer day delay?
When will Time flow away?
