“Come up to London,” said Leslie. “Well, that is what we surmised before we applied to you.”

“We must have time, sir. A hunter does not secure his game by rushing at it. He stalks it.”

“If you are successful in finding their whereabouts, mind that your task ends there. You will give us due notice, and we will see to the rest.”

“Certainly, sir; and I have men on the look-out. The bundle of hay is being pretty well tossed over, and some day I hope to see the shine of the needle among the puzzling dry strands. Good morning.”

“Is that man a humbug, sir, or in earnest?”

“Earnest,” replied Uncle Luke. “He proved that before.”
