“I had the same trouble when I opened it,” said Frank, who was hurrying into his clothing as rapidly as possible.

“The confounded thing won’t come down, and that settles it,” cried Bob, hopelessly.

“Never mind, let it go. I am ready to start.”

Frank moved swiftly toward the door and unlocked it. As he did so, the face of Raymond appeared at the window.

“Quick!” whispered the young man, and he flung open the door for Bob to pass through.
