"I'm sure the trees do not belong to these awful creatures. They are fit for any mischief, and it's my opinion they would try to kill us just the same if you hadn't picked a dinner-pail."
"I think so, too," agreed Dorothy. "But what shall we do now?"
"Stay where we are," advised the yellow hen. "We are safe from the Wheelers until we starve to death, anyhow; and before that time comes a good many things can happen."
4. Tiktok the Machine Man
After an hour or so most of the band of Wheelers rolled back into the forest, leaving only three of their number to guard the hill. These curled themselves up like big dogs and pretended to go to sleep on the sands; but neither Dorothy nor Billina were fooled by this trick, so they remained in security among the rocks and paid no attention to their cunning enemies.
Finally the hen, fluttering over the mound, exclaimed: "Why, here's a path!"
So Dorothy at once clambered to where Billina sat, and there, sure enough, was a smooth path cut between the rocks. It seemed to wind around the mound from top to bottom, like a cork-screw, twisting here and there between the rough boulders but always remaining level and easy to walk upon.
Indeed, Dorothy wondered at first why the Wheelers did not roll up this path; but when she followed it to the foot of the mound she found that several big pieces of rock had been placed directly across the end of the way, thus preventing any one outside from seeing it and also preventing the Wheelers from using it to climb up the mound.
Then Dorothy walked back up the path, and followed it until she came to the very top of the hill, where a solitary round rock stood that was bigger than any of the others surrounding it. The path came to an end just beside this great rock, and for a moment it puzzled the girl to know why the path had been made at all. But the hen, who had been gravely following her around and was now perched upon a point of rock behind Dorothy, suddenly remarked:
"It looks something like a door, doesn't it?"
"What looks like a door?" enquired the child.
"Why, that crack in the rock, just facing you," replied Billina, whose little round eyes were very sharp and seemed to see everything. "It runs up one side and down the other, and across the top and the bottom."
"What does?"
"Why, the crack. So I think it must be a door of rock, although I do not see any hinges."
"Oh, yes," said Dorothy, now observing for the first time the crack in the rock. "And isn't this a key-hole, Billina?" pointing to a round, deep hole at one side of the door.
"Of course. If we only had the key, now, we could unlock it and see what is there," replied the yellow hen. "May be it's a treasure chamber full of diamonds and rubies, or heaps of shining gold, or--"
"That reminds me," said Dorothy, "of the golden key I picked up on the shore. Do you think that it would fit this key-hole, Billina?"
"Try it and see," suggested the hen.
So Dorothy searched in the pocket of her dress and found the golden key. And when she had put it into the hole of the rock, and turned it, a sudden sharp snap was heard; then, with a solemn creak that made the shivers run down the child's back, the face of the rock fell outward, like a door on hinges, and revealed a small dark chamber just inside.
"Good gracious!" cried Dorothy, shrinking back as far as the narrow path would let her.
For, standing within the narrow chamber of rock, was the form of a man--or, at least, it seemed like a man, in the dim light. He was only about as tall as Dorothy herself, and his body was round as a ball and made out of burnished copper. Also his head and limbs were copper, and these were jointed or hinged to his body in a peculiar way, with metal caps over the joints, like the armor worn by knights in days of old. He stood perfectly still, and where the light struck upon his form it glittered as if made of pure gold.
"Don't be frightened," called Billina, from her perch. "It isn't alive."
"I see it isn't," replied the girl, drawing a long breath.
