"Molasses, boss," said Spike, deferentially.

He poured the contents of the bottle on a piece of paper, which he pressed firmly against the window-pane. Then, drawing out a short steel instrument, he gave the paper a sharp tap. The glass broke almost inaudibly. The paper came away, leaving a gap in the pane. Spike inserted his hand, shot back the catch, and softly pushed up the window.

"Elementary," said Jimmy; "elementary, but quite neat."

There was now a shutter to be negotiated. This took longer, but in the end Spike's persuasive methods prevailed.

Jimmy became quite cordial.

"You have been well-grounded, Spike," he said. "And, after all, that is half the battle. The advice I give to every novice is, 'Learn to walk before you try to run.' Master the a, b, c, of the craft first. With a little careful coaching, you will do. Just so. Pop in."

Spike climbed cautiously over the sill, followed by Jimmy. The latter struck a match, and found the electric light switch. They were in a parlor, furnished and decorated with surprising taste. Jimmy had expected the usual hideousness, but here everything from the wall-paper to the smallest ornaments was wonderfully well selected.

Business, however, was business. This was no time to stand admiring artistic effects in room-furnishing. There was that big J to be carved on the front door. If 'twere done, then 'twere well 'twere done quickly.

He was just moving to the door, when from some distant part of the house came the bark of a dog. Another joined in. The solo became a duet. The air was filled with their clamor.

"Gee!" cried Spike.
