The burros trotted tirelessly; the dogs, once more free, pattered tirelessly; and Lassiter led on with never a stop, and at every open place he looked back.

The shade under the walls gave place to sunlight.

And presently they came to a dense thicket of slender trees, through which they passed to rich, green grass and water.

Here Lassiter rested the burros for a little while, but he was restless, uneasy, silent, always listening, peering under the trees.

She dully reflected that enemies were behind them--before them; still the thought awakened no dread or concern or interest.
At his bidding she mounted and rode on close to the heels of his burro.
The canyon narrowed; the walls lifted their rugged rims higher; and the sun shone down hot from the center of the blue stream of sky above.
Lassiter traveled slower, with more exceeding care as to the ground he chose, and he kept speaking low to the dogs.
