The three-horned dinosaur was now fleeing madly for its life! But Renny had no way of knowing that. He happened to be directly in the path of the thing. There was no time for a leap sidewise.
'Only one chance!' Renny gritted — and sprang high into the air, flinging his two-hundred-and-fifty-pound frame directly between the two massive horns set over the dinosaur’s eyes.
Renny’s hands, each one a gallon of knuckles, clasped the horns. They clung tightly.
When the hulking beast ran straight forward, not even shaking its vast head, Renny merely hung on. The space between the horns was ample to accommodate him. The smaller lower horn furnished a footrest.
'If I get off, the thing will turn on me!' Renny reasoned — wrongly.
This particular dinosaur was a peace lover, despite its formidable looks. Its only idea now was to get away from the terrible tyrannosaurus. Such a small object as Renny clinging to its head bothered it not at all for the time being.
The steam was dissipating now, and Renny could take in his surroundings. His amazing steed had a bald skin. It reminded Renny of an elephant’s hide, although rougher and thicker. It was hard as sole leather to his touch.
'A bullet wouldn’t faze the thing!' he decided.
RENNY'S scant knowledge was sufficient to inform him the major portion of this creature’s brain probably lay in its spine. It was even likely the spinal cord served as a brain, a function not uncommon in the prehistoric members of the dinosaur tribe.
The stampeding beast wallowed through a small body of water without slackening pace. Renny was drenched. He noted the water was very warm, like piping hot coffee. It did not scald, though.
The breathing of Renny’s conveyance was becoming labored. The thing was short of wind. Renny began to have an unpleasant feeling it would soon stop. He wondered how he would dismount without meeting disaster.
The problem solved itself.
Blindly, as unvarying in its wild course as a bullet, the triceratops hit a great tangle of lianas and ferns and small coniferous trees. It gauged through by main strength.
Renny was left behind, hanging over a vine!
To this vine Renny clung for a time. He listened. The ground was about seven feet below. Renny didn’t know but what other predatory monsters might be about. He glanced up nervously, fearing sight of the gruesome, batlike flying reptiles.
Exploring, Renny found he still had his pistol-like machine gun.
'Wish I had a pocketful of hand grenades too!' he muttered. He dropped down from the liana and set out on the triceratops’s back trail. He found traveling difficult. Clinging creepers and packed ferns interfered.
Renny had penetrated the thick jungles of the upper Amazon. He had explored in rankest Africa. But he had never seen a jungle which approached this for denseness. Without the path the dinosaur had opened, Renny would have been baffled.
As it was, he had to be alert steadily, lest he stumble into the waist-deep tracks of the monster.
He soon noted the unusual character of the growth. Many of the trees were of a type he had never seen before. But others had a familiar look.
'The ones I don’t recognize became extinct ages ago,' he concluded. 'The others, more fitted to changing conditions in the outside world, survived.'
Renny chuckled. He felt exhilarated, now that he had escaped with his life.
'What I mean, this is a sure-enough example of how evolution has worked on the rest of the world!'
Suddenly came the dismaying knowledge that night had almost arrived.
Renny was conservative. He knew the safe thing to do.
'I’ll hunt a tree for the night!' he concluded.
But he was not fortunate enough to be in a region of tall growth. He saw that climbing any of the small ferns or evergreen trees about him would not give him safety from the hulking dinosaurs.
He began to run, hoping to reach Doc before darkness. But, as though the very moist, depressively hot air were turning a jet-black ink, night started closing in.
Sprinting, Renny reached the body of water through which his huge steed had plowed. About to plunge in, he hesitated. A great gurgling arose beyond the enormous rushes that edged the shore. The sound was like huge tanks of water emptying in succession. Then a vast body, which was apparently dunking up and down and making the noises, must have rolled over.
A miniature tidal wave came boiling inshore. It reached above Renny’s knees! What a monster this prehistoric beast must be!
Over the rushes suddenly projected what Renny at first took to be the head and neck of a snake. A work- a-day-world serpent magnified a thousandfold! A large barrel could not have held the head!
For all its snaky look and fantastic size, the head had a peaceful look, though. A repetition of the loud water noises showed that the long, lithe neck was attached to a monster body.
Slowly, the weird beast came dragging out of the water.
RENNY felt a ticklish sensation in his scalp, which might have been his hair standing on end.
The thing was longer than a freight car!
'Good — ' Renny spun and fled.
He knew he had just looked at a member of the family of largest creatures ever to tread the earth. Even the ferocious, meat-eating killer, the tyrannosaurus, was eclipsed by the bulk of this colossus.
The great reptile he had just seen was a 'thunder lizard,' or brontosaurus.
Renny recalled they were popularly supposed to be peaceful giants, haunting the water and feeding on lake plants and shore growth. The theory held by scientists is that they were not meat devourers.
Renny had no desire to test the accuracy of that theory. Compared to the thunder lizard in size, he was like a mouse beside a fat hog. He didn’t know but what the beast might decide to try a man for a change of diet.
So Renny ran for all he was worth. The thunder lizard, apparently curious or playful, lumbered after him. The earth shook in a pronounced manner under its incalculable weight.
Quitting the trail opened by the armor-plated monster which had brought him here, Renny dived into the tangled vegetation. He lost his hundreds of tons of gamboling pursuer.
'Whew!' He mopped his forehead with both sleeves. 'Whew!'
He felt his way onward, machine gun ready in one hand. So dark had become the night that he could not even see the weapon he held. He halted often to listen to the awful uproar of the night.
Once a nocturnal fray broke out near by, and the course of the battle brought it directly for Renny! He fled madly. Strong in his nostrils was the fetid, near-suffocating odor of a great carnivore. He knew here was genuine danger! It was another of the monster killers of prehistoric ages, a tyrannosaurus. His parachute had fallen upon one of those!
Renny crept away, marveling at the variety of ear-splitting sounds emitted by the weird beasts of the crater. He reasoned the things could see somewhat in the darkness. He had noticed the eyes of the reptiles were particularly fitted for vision in restricted light. But in darkness such as this, it was impossible for them to see much. They must hunt largely by the sense of hearing, perhaps some of them with the organ of smell.
'What a place to have to live in!' he muttered.
It was only a moment later that fresh disaster overtook him.
Came a great fluttering sound from above his head! It was as if some one were shaking a large carpet up there.
'What the — ' Then Renny knew what it was. One of the flying reptiles! A pterodactyl — one of the horrors which had disabled their plane!
Wildly, Renny flung up his gun.
But before he could pull the trigger, the gruesome marauder was upon him!
RENNY now got one of the few pleasant surprises of the night. He realized this aлrial, batlike thing was much smaller than the one which had assailed the plane. Probably it was a chick of the species!
