He had dismounted, thinking at the spring
To spend the night—and then the grisly thing—
Of course the horse had bolted; plain enough!
But why was all the soil about so rough
As though a herd of horses had been there?
The riddle vexed him till his vacant stare
Fell on a heap of earth beside a pit.
What did that mean? He wormed his way to it,
The newly wakened wonder dulling pain.
No paw of beast had scooped it—that was plain.
