"I'll look it over," said Bell, briefly. He swung down the catwalk painted on the wings. He began a swift and hasty survey. Soot on the exhaust stacks proved that the motors had been tried, at least. Everything seemed trim and new and glistening in the cabin. The fuel tanks showed the barest trace of fuel. The oil tanks were full to their filling-plugs. He swung back up. "Taking a chance, of course," he said curtly. "If the motors were all right when they were tried, they probably are all right now. They may have been tuned up, and may not. I tried the controls, and they seem to work. For a new ship, of course, a man would like to go over it carefully, but if we've got to hurry...." "I think," said Ortiz, and laughed, "that haste would be desirable. Herr Wiedkind--No! _Amigo mio_, it was that damned Antonio Calles who listened to us last night. I found pencil marks beside the listening instrument. He must have sat there and eavesdropped upon me many weary hours, and scribbled as men do to pass the time. He had a pretty taste in monograms.... I gave all the orders that were needful for you to take off from the flying field. I even went there myself and gave additional orders. And Calles was there. Also others of The Master's subjects. My treason would provoke a terrible revenge from The Master, so they thought to prove their loyalty by permitting me to disclose my plan and foil it at its beginning. "I would have made the journey with you to The Master, but as a prisoner with the tale of my treason written out. So I returned and changed the orders to the chauffeur, when all the Master's loyal subjects were waiting at the flying field. But soon it will occur to them what I have done. They will come here. Therefore, hasten!" "We want food," said Bell evenly, "and arms, but mostly we want fuel. We'll get busy." * * * * * He shed his coat and picked up a hand-truck. He rammed it under a drum of gasoline and ran it to the walkway nearest to the floating plane. Coiled against the wall there was a long hose with a funnel at its upper end. In seconds he had the hose end in one of the wing fuel-tanks. In seconds more he had propped the funnel into place and was watching the gasoline gurgling down the hose. "Paula," he said curtly, "watch this. When it's empty roll the drum away so I can put another in its place." She moved quickly beside it, throwing him a little smile. She set absorbedly about her task.
