When the adventurers reassembled upon the roof it was found that a remarkably queer assortment of articles had been selected by the various members of the party. No one seemed to have a very clear idea of what was required, but all had brought something.

The Woggle-Bug had taken from its position over the mantle-piece in the great hallway the head of a Gump, which was adorned with wide-spreading antlers; and this, with great care and greater difficulty, the insect had carried up the stairs to the roof. This Gump resembled an Elk's head, only the nose turned upward in a saucy manner and there were whiskers upon its chin, like those of a billy-goat. Why the Woggle-Bug selected this article he could not have explained, except that it had aroused his curiosity.

Tip, with the aid of the Saw-Horse, had brought a large, upholstered sofa to the roof. It was an oldfashioned piece of furniture, with high back and ends, and it was so heavy that even by resting the greatest weight upon the back of the Saw-Horse, the boy found himself out of breath when at last the clumsy sofa was dumped upon the roof.

The Pumpkinhead had brought a broom, which was the first thing he saw. The Scarecrow arrived with a coil of clothes-lines and ropes which he had taken from the courtyard, and in his trip up the stairs he had become so entangled in the loose ends of the ropes that both he and his burden tumbled in a heap upon the roof and might have rolled off if Tip had not rescued him.

The Tin Woodman appeared last. He also had been to the courtyard, where he had cut four great, spreading leaves from a huge palm-tree that was the pride of all the inhabitants of the Emerald City.

"My dear Nick!" exclaimed the Scarecrow, seeing what his friend had done; "you have been guilty of the greatest crime any person can commit in the Emerald City. If I remember rightly, the penalty for chopping leaves from the royal palm-tree is to be killed seven times and afterward imprisoned for life."

"It cannot be helped now" answered the Tin Woodman, throwing down the big leaves upon the roof. "But it may be one more reason why it is necessary for us to escape. And now let us see what you have found for me to work with."

Many were the doubtful looks cast upon the heap of miscellaneous material that now cluttered the roof, and finally the Scarecrow shook his head and remarked:

"Well, if friend Nick can manufacture, from this mess of rubbish, a Thing that will fly through the air and carry us to safety, then I will acknowledge him to be a better mechanic than I suspected."

But the Tin Woodman seemed at first by no means sure of his powers, and only after polishing his forehead vigorously with the chamois-leather did he resolve to undertake the task.

"The first thing required for the machine," said he, "is a body big enough to carry the entire party. This sofa is the biggest thing we have, and might be used for a body. But, should the machine ever tip sideways, we would all slide off and fall to the ground."

"Why not use two sofas?" asked Tip. "There's another one just like this down stairs."

"That is a very sensible suggestion," exclaimed the Tin Woodman. "You must fetch the other sofa at once."

So Tip and the Saw-Horse managed, with much labor, to get the second sofa to the roof; and when the two were placed together, edge to edge, the backs and ends formed a protecting rampart all around the seats.

"Excellent!" cried the Scarecrow. "We can ride within this snug nest quite at our ease."

The two sofas were now bound firmly together with ropes and clothes-lines, and then Nick Chopper fastened the Gump's head to one end.

"That will show which is the front end of the Thing," said he, greatly pleased with the idea. "And, really, if you examine it critically, the Gump looks very well as a figure-head. These great palm-leaves, for which I have endangered my life seven times, must serve us as wings."

"Are they strong enough?" asked the boy.

"They are as strong as anything we can get," answered the Woodman; "and although they are not in proportion to the Thing's body, we are not in a position to be very particular."

So he fastened the palm-leaves to the sofas, two on each side.
