Analysis of In falling Timbers buried

In falling Timbers buried—
There breathed a Man—
Outside—the spades—were plying—
The Lungs—within—

Could He—know—they sought Him—
Could They—know—He breathed—
Horrid Sand Partition—
Neither—could be heard—

Never slacked the Diggers—
But when Spades had done—
Oh, Reward of Anguish,
It was dying—Then—

Many Things—are fruitless—
'Tis a Baffling Earth—
But there is no Gratitude
Like the Grace—of Death—
