Presently he tired of this amusement, and, dropping from branch to branch, he squatted down into the old attitude and moved towards the stables, creeping along in the same strange way as before. The wolfhound was out now, barking furiously, and more excited than ever when it actually caught sight of its master. It was straining on its chain and quivering with eagerness and rage.

Consider, Watson, that the material, the sensual, the worldly would all prolong their worthless lives. The spiritual would not avoid the call to something higher. It would be the survival of the least fit. What sort of cesspool may not our poor world become?" Suddenly the dreamer disappeared, and Holmes, the man of action, sprang from his chair.
