Bowlegs touched a spring with his foot, and the chair containing the stunned detective sank from sight.

The tramp stared at the opening in the floor wonderingly.

"I declare!" he finally exclaimed, "you've got this thing in shape to work to perfection, pardner."

The saloon-keeper smiled without reply.

"Where's the chap gone ter?"

"He is safe," answered Bowlegs. "I'll excuse you now."

"Wal, I swar, that are's cool."

Nevertheless the tramp departed. At the bar he swallowed a huge glass of brandy, and then passed upon the street.

From this it will be seen that Billy Bowlegs was in league with the notorious scoundrel who is known to the reader as Andrew Barkswell.

This, it will be remembered, was on the same night that the robbery was committed at the Alstine mansion.
