"I scarcely follow you," I said, somewhat puzzled. "I mean that every man, no matter what his station in life, is ready to perform services for another, providing the sum is sufficient in payment." I smiled at his philosophy. "There is a good deal of truth in that," I remarked; "but of course there are exceptions." "Are you one?" he inquired sharply, in a strange voice. I hesitated.

"But in this matter there must be no hesitation on our part; it
