broken into a confused buzzing as the terrified, blinded beetles plopped into the stream.
None of them, fortunately, fell into either of the three shells, but the mass of struggling monsters in the water was hardly less formidable to the safety of the occupants than that menacing cloud overhead.
"Get clear!" Tommy yelled to Dodd, trying to help the shell along with his hands.
HE heard Bram's cry of baffled rage, and, looking backward, could not refrain from a laugh of triumph. Bram's trained steeds had taken fright and overset him. Bram had fallen into the red mud beside the stream, from which he was struggling up, plastered from head to feet, and shaking his fists and evidently cursing, though his words could not be heard.
"How about your marsupial lion now, Bram?" yelled Dodd. "No monotremes before the pleistocene! D'you get that? That's my slogan now and for ever more!"
Bram shrieked and raved, and seemed to be inciting the beetles to a renewed assault. The air was still thick with them, but Tommy was waving the cigarette-lighter in a flaming arc, which cleared the way for them.
Then suddenly came disaster. The flame went out! Tommy closed the lighter with a snap and opened it. In vain. In his excitement he must have spilled all the contents, for it would not catch.
Bram saw and yelled derision. The beetle-cloud was thickening. Tommy, now abreast of his companions on the widening stream, saw the imminent end.
AND then once more fate intervened. For, leaping through the air out of the places where they had lain concealed, six mantises launched themselves at their beetle prey.
Those awful bounds of the long-legged monsters, the scourges of the insect world, carried them clear from one bank to the other--fortunately for the occupants of the shells. In an instant the beetle-cloud dissolved. And it had all happened in a few seconds. Before Dodd or Tommy had quite taken in the situation, the mantises, each carrying a victim in its grooved legs, had vanished like the beetles. There was no sign of Bram. The three were alone upon the face of the stream, which went swirling upward into renewed darkness.
Tommy saw Dodd bend toward Haidia as she lay on her shell couch. He heard the sound of a noisy kiss. And he lay back in the hollow of his shell, with the feeling that nothing that could happen in the future could be worse than what they had passed through.
DAYS went by, days when the sense of dawning freedom filled their hearts with hope. Haidia told Dodd and Tommy that, according to the legends of her people, the river ran into the world from which they had been driven by the floods, ages before.
There had been no further signs of Bram or the beetle horde, and Dodd and Tommy surmised that it had been disorganized by the attack of the mantises, and that Bram was engaged in regaining his control over it. But neither of them believed that the respite would be a long one, and for that reason they rested ashore only for the briefest intervals, just long enough to snatch a little sleep, and to eat some of the shrimps that Haidia was adept at finding--or to pull some juicy fruit surreptitiously from a tree.
Incidents there were, nevertheless, during those days. For hours their shells were followed by a school of the luminous river monsters, which, nevertheless, made no attempt to attack them. And once, hearing a cry from Haidia, as she was gathering shrimps, Dodd ran forward to see her battling furiously with a luminous scorpion,
