"They've crashed in the door, and are pumping out the water again!" exclaimed Abbot. "We're trapped!"
"Not yet!" grimly replied the girl at his side. "Can you work the radio door controls?"
"Yes."
"Then quick! Open the doors into the lock!"
He pressed a button. Ahead of them two gates swung inward, followed by a deluge of water.
"Come on!" spoke the girl. "Full speed ahead, before the water gets too low."
Abbot did so. Out into the lock they sped, in the face of the surging current. Then Abbot pushed another button to close the gates behind them. But the water continued to fall, and they grounded before they reached the end of the lock. Quite evidently the rush of the current had kept the doors from closing behind them. The city was being flooded through the broken door of the storeroom.
But Abbot opened the next gate, and again they breasted the incoming torrent. This time, although the level continued to fall, their craft did not quite ground.
"They must have got the gates shut behind us at last," said he, as he opened the next set and pressed on.
