Dunn did not reply, but, buttoning his coat, placed one hand on his companion's shoulder, and sullenly bade him "lead the way." Advancing slowly and with difficulty, the desperate man might have been taken for a peaceful invalid returning from an early morning stroll. His right hand was buried thoughtfully in the side-pocket of his coat. Only Brace knew that it rested on the handle of his pistol.
From time to time the latter stopped and consulted the faint trail with a minuteness that showed recent careful study. Suddenly he paused. "I made a blaze hereabouts to show where to leave the trail. There it is," he added, pointing to a slight notch cut in the trunk of an adjoining tree.
"But we've just passed one," said Dunn, "if that's what you are looking after, a hundred yards back."
Brace uttered an oath, and ran back in the direction signified by his companion. Presently he returned with a smile of triumph.
"They've suspected something. It's a clever trick, but it won't hold water. That blaze which was done to muddle you was cut with an axe; this which I made was done with a bowie-knife. It's the real one. We're not far off now. Come on."
They proceeded cautiously, at right angles with the "blazed" tree, for ten minutes more. The heat was oppressive; drops of perspiration rolled from the forehead of the sheriff, and at times, when he attempted to steady his uncertain limbs, his hands shrank from the heated, blistering bark he touched with ungloved palms.
"Here we are," said Brace, pausing at last. "Do you see that biggest tree, with the root stretching out half-way across to the opposite one?"
"No; it's further to the right and abreast of the dead brush," interrupted Dunn quickly, with a sudden revelation that this was the spot where he had found the dead bear in the night Teresa escaped.
"That's so," responded Brace, in astonishment.
"And the opening is on the other side, opposite the dead brush," said Dunn.
