Analysis of Spring Mud

There is a smell in the Spring
That does within me ring a bell
A strange and curious smell
That rings that bell
A malodorous pungent smell
The scent of spring decay
At a time before May
Deep within the earth in the mud
The earth again renews its blood
The snow has wet and melted
The Flora that dwelt it
The decay seeps up from underground
And leaves a strange smell around
Just for a couple of days
Before the beginning of May
