The Chemist smiled. "What you say is quite true, Jack, we have got to have food and water; those are the only things necessary to our trip."

"We can make ourselves small now and have supper," suggested the Very Young Man. "Then we can fill up the bottles for our belts and take enough food for the trip."

"No, we won't," interposed the Big Business Man positively. "We won't get small again. Something might happen. Once we get through the tunnels——" He stopped abruptly.

"Great Scott! We never thought of that," ejaculated the Very Young Man, as the same thought occurred to him. "We'll have to get small to get through the tunnels. Suppose there's a mob there that won't let us in?"

"Is there any other way up to the forest?" the Doctor asked.

The Chemist shook his head. "There are a dozen different tunnels, all near here, and several at Orlog, that all lead to the upper surface. But I think that is the only way."

"They might try to stop us," the Big Business Man suggested. "We certainly had better get through them as quickly as we possibly can."

It was Aura who diffidently suggested the plan they finally adopted. They all reduced their size first to about the height of the Chemist's house. Then the Very Young Man prepared to make himself sufficiently small to get the food and water-bottles, and bring them up to the larger size.

"Keep your eye on me," he warned. "Somebody might jump on me."

They stood around the house, while the Very Young Man, in the garden, took the drug and dwindled in stature to Oroid size. There were none of the Oroids in sight, except some on the beach and others up the street silently watching. As he grew smaller the Very Young Man sat down wearily in the wreck of what once had been Lylda's beautiful garden. He felt very tired and hungry, and his head was ringing.
