He found himself in a side room, smaller than the outer chamber, the whole center of which was occupied by a huge glass bell jar, some thirty feet in diameter. Inside it was much strange-looking apparatus on tables, and trays of operating instruments--knives like those in the outer room, and the same thin prongs. The great jar was empty of water, and on one side was an entrance port. The king tossed Keith into a corner and quickly donned a metal-scaled water-suit. When he had it all on, and the glass body-container fastened into place, he picked up his captive again and advanced through the bell jar's entrance port into a small water chamber. A moment later Wells felt his body grow heavy as the water of the compartment ran out, and then there was a click and he found himself inside the jar, still held in the merciless grip of a tentacle. He twisted around to find the cold eyes of the octopus staring at him only a foot away. And as he wondered what was going to happen next, the king unfastened the glass face-shield of the commander's sea-suit with a quick flip of the tip of a tentacle. Keith's arms were pinned to his sides; he could not move to try to refasten the face-shield. Fearful, he held his breath; held it until his face was purple and his lungs were near to bursting. But at last the limit was reached, and with a great wrench he sucked in a full breath. It was clean, fresh air! * * * * * The air was like a breath of his own world brought down to this cold realm of octopi. Once he had caught up with his breathing it poured new life into his limbs, jaded from the artificial air of the sea-suit. Keith felt his muscles respond, felt his whole body glow with new strength and life. Twelve inches away the king was watching his every reaction closely through the huge helmet of glass. The thought passed through the commander's mind that he was not only king, but chief scientist of this strange water civilization. Then, while his lungs swallowed hungrily the good, fresh air, several tentacles began to feel around him in an attempt to unfasten the rest of his sea-suit. Wells blanched at the sudden realization of how helpless he would be if the suit were taken from him. He would then not only be a prisoner of the octopi, but a prisoner of the glass jar, unable ever to leave it, and more than ever at the mercy of his captor's least whim. Not that he had any delusion that he would live long in any case: it was just the simple strong instinct of self-preservation that made him grab at every chance for life. This thought flashed through his mind, even while the octopus was fumbling with the catches of his suit. And along with it was born a desperate plan of escape. He was in his own element, air; the octopus out of his. If he could crack the glass of the king's helmet, and let the water out and air in!... The glass was only twelve inches away.
