Yearly their Eggs the pregnant Females lay,
One annual Birth restores the vast Decay.
But twice  the coming Sorrow mourn;
Again the Joys, again the Pangs return.
Three yearly Spawns the teeming  bless,
Renew the Race, and give the large Increase.
The curling  in each Season knows,
The glad Conception, and the wringing Throws.
But  all Kinds in num'rous Births exceed,
They still unweary'd with their Labour breed.
With five successive Spawns the  abound
E'er the swift Sun has trac'd his annual Round.
