Swallow Egg

Gentle swallow that we know
Every year dost come and go,
In the spring thy nest thou mak'st
In the winter it foresak'st
And divert'st thyself a while
Near the Memphian towers, or Nile:
But love in my suffering breast
Builds and never quits his nest
First one love's hatched;when that flies
In the shell another lies,
Then a third is half exposed'
Then a whole brood is disclos'd
Which for meat still peeping cry,
Whilst the others that can fly
Do their callow brethren feed,
And grow up, they young ones breed.
What will become of me
Bound to pain incessantly.
Whilst so many loves conspire
of my heart by turns to tire?
