Once Wahb decided to retreat, it was all too easy to do so next time; and the result worked double disaster. For, since the big stranger was allowed possession of the sulphur-spring, Wahb felt that he would rather not go there. Sometimes when he came across the traces of his foe, a spurt of his old courage would come back. He would rumble that thunder-growl as of old, and go painfully lumbering along the trail to settle the thing right then and there. But he never overtook the mysterious giant, and his rheumatism, growing worse now that he was barred from the cure, soon made him daily less capable of either running or fighting. Sometimes Wahb would sense his foe's approach when he was in a bad place for fighting, and, without really running, he would yield to a wish to be on a better footing, where he would have a fair chance. This better footing never led him nearer the enemy, for it is well known that the one awaiting has the advantage. Some days Wahb felt so ill that it would have been madness to have staked everything on a fight, and when he felt well or a little better, the stranger seemed to keep away. [Illustration] Wahb soon found that the stranger's track was most often on the Warhouse and the west slope of the Piney, the very best feeding-grounds. To avoid these when he did not feel equal to fighting was only natural, and as he was always in more or less pain now, it amounted to abandoning to the stranger the best part of the range. [Illustration] Weeks went by. Wahb had meant to go back to his bath, but he never did. His pains grew worse; he was now crippled in his right shoulder as well as in his hind leg. The long strain of waiting for the fight begot anxiety, that grew to be apprehension, which, with the sapping of his strength, was breaking down his courage, as it always must when courage is founded on muscular force. His daily care now was not to meet and fight the invader, but to avoid him till he felt better. Thus that first little retreat grew into one long retreat. Wahb had to go farther and farther down the Piney to avoid an encounter. He was daily worse fed, and as the weeks went by was daily less able to crush a foe.
