As soon as he got to the part where he had to pull the Witch's hat down over her head, he said, "I'll keep my eye on the clock and let you know when the half hour is up." With that, he jammed the hat down over her eyes and down to her shoulders and then made a beeline for the window.
After Graham had escaped from the castle, he thought about the Witch standing there for a full half-hour and thinking how beautiful she was going to be when she took the hat off and looked at herself in her mirror. He laughed out loud as he imagined how she would really look with that gooey mess all over her hair and face and clothes. But he knew that once the reality dawned on her that the spell was a fake, that she was just as ugly as ever, and that he had escaped, she would be absolutely beside herself with rage. The boy's elation began to change to fear as he considered the possible repercussions of his actions. Here he was in a strange yellow land with no idea of where he was going or where to hide.
He had been traveling through a wooded area which, for now, offered some measure of security, since he would be hidden from aerial surveillance, when he came upon a clearing. Actually, it was more than just a clearing; it was a perfectly round grassy clearing about fifty feet in diameter, and dome-shaped. As he studied the dome, it began to slowly rise, exposing a round house with windows and doors and a grass-covered roof. Graham stood perfectly still, waiting to see if anyone came out. When it was obvious that no one was coming, he cautiously walked toward the house to see if he could see through the window. Suddenly, a loud, mechanical-sounding voice filled the air. "WARNING! YOU ARE APPROACHING TOO CLOSE TO THE VEHICLE. PLEASE STEP BACK."
At this point, Graham was more than a little confused. He knew that this sort of proximity alarm system was favored by some motor vehicle owners back home. But the device seemed very out of place in Oz. Not to mention the fact that the sound was emanating from a house, not a car. At that moment, the round roof slowly started to spin and rose about four feet above the house and hovered there. The outside walls receded back into the ground to reveal a bright, shiny spaceship shimmering in the sunlight. A ramp unfolded to reveal two equally shimmering space beings. They descended (or rather, floated) down the ramp and stopped less than three feet from the boy. They were not very tall--about four feet in height--and they were dressed in metallic-looking one-piece spacesuits that closely followed the contour of their slender bodies. They had quite large heads, which were somewhat out of proportion to their overall physique. Their eyes were large and doe-shaped and were the blackest of black with no pupils visible. He sensed an intelligence emanating from their eyes that was far in excess of ordinary people. Their skin was of a dull grayish hue; no color at all.
