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.
