A traveller was making his way through the Black Forest in Germany. A pack was on his back, of a size which required a stout man to carry it, and a thick staff was in his hand. He had got out of his path by attempting to make a short cut, and in so doing had lost his way, and had been since wandering he knew not where. Yet he was stout of heart, as of limb, and a night spent in the depths of the forest would have concerned him but little had he not set a value upon time. "I have lost so much in my days of ignorance and folly," he kept saying, "that I must make up by vigilance what has been thus misspent. I wish that I had known better. However, I am now ready to spend all, and be spent in the work of the Good Master I serve." (From Chapter one)
