Nowhere about them could Bradley see signs of other Wieroos, nor of those other menaces which he had feared might bring disaster to his plans for escape--the huge, winged reptilia that are so numerous above the southern areas of Caspak and which are often seen, though in lesser numbers, farther north.
Nearer and nearer loomed the mainland--a broad, parklike expanse stretching inland to the foot of a low plateau spread out before them.
The little dots in the foreground became grazing herds of deer and antelope and bos; a huge woolly rhinoceros wallowed in a mudhole to the right, and beyond, a mighty mammoth culled the tender shoots from a tall tree. The roars and screams and growls of giant carnivora came faintly to their ears. Ah, this was Caspak.
With all of its dangers and its primal savagery it brought a fullness to the throat of the Englishman as to one who sees and hears the familiar sights and sounds of home after a long absence.
Then the Wieroos dropped swiftly downward to the flower-starred turf that grew almost to the water's edge, the fugitives slipped from their backs, and Bradley told the red-robed creatures they were free to go.
When he had cut the ropes from their ankles they rose with that uncanny wailing upon their lips that always brought a shudder to the Englishman, and upon dismal wings they flapped away toward frightful Oo-oh.
When the creatures had gone, the girl turned toward Bradley.
"Why did you have them bring us here?" she asked. "Now we are far from my country. We may never live to reach it, as we are among enemies who, while not so horrible will kill us just as surely as would the Wieroos should they capture us, and we have before us many marches through lands filled with savage beasts."
"There were two reasons," replied Bradley. "You told me that there are two Wieroo cities at the eastern end of the island.
To have passed near either of them might have been to have brought about our heads hundreds of the creatures from whom we could not possibly have escaped. Again, my friends must be near this spot--it cannot be over two marches to the fort of which I have told you.
It is my duty to return to them. If they still live we shall find a way to return you to your people."
"And you?" asked the girl.
"I escaped from Oo-oh," replied Bradley. "I have accomplished the impossible once, and so I shall accomplish it again--I shall escape from Caspak."
He was not looking at her face as he answered her, and so he did not see the shadow of sorrow that crossed her countenance.
When he raised his eyes again, she was smiling.
"What you wish, I wish," said the girl.
Southward along the coast they made their way following the beach, where the walking was best, but always keeping close enough to trees to insure sanctuary from the beasts and reptiles that so often menaced them. It was late in the afternoon when the girl suddenly seized Bradley's arm and pointed straight ahead along the shore. "What is that?" she whispered. "What strange reptile is it?"
Bradley looked in the direction her slim forefinger indicated.
He rubbed his eyes and looked again, and then he seized her wrist and drew her quickly behind a clump of bushes.
"What is it?" she asked.
"It is the most frightful reptile that the waters of the world have ever known," he replied. "It is a German U-boat!"
An expression of amazement and understanding lighted her features.
"It is the thing of which you told me," she exclaimed, "--the thing that swims under the water and carries men in its belly!"
"It is," replied Bradley.
"Then why do you hide from it?" asked the girl. "You said that now it belonged to your friends."
"Many months have passed since I knew what was going on among my friends," he replied. "I cannot know what has befallen them.
They should have been gone from here in this vessel long since, and so I cannot understand why it is still here. I am going to investigate first before I show myself. When I left, there were more Germans on the U-33 than there were men of my own party at the fort, and I have had sufficient experience of Germans to know that they will bear watching--if they have not been properly watched since I left."
Making their way through a fringe of wood that grew a few yards inland the two crept unseen toward the U-boat which lay moored to the shore at a point which Bradley now recognized as being near the oil-pool north of Dinosaur. As close as possible to the vessel they halted, crouching low among the dense vegetation, and watched the boat for signs of human life about it. The hatches were closed--no one could be seen or heard. For five minutes Bradley watched, and then he determined to board the submarine and investigate. He had risen to carry his decision into effect when there suddenly broke upon his ear, uttered in loud and menacing tones, a volley of German oaths and expletives among which he heard Englische schweinhunde repeated several times.
The voice did not come from the direction of the U-boat; but from inland. Creeping forward Bradley reached a spot where, through the creepers hanging from the trees, he could see a party of men coming down toward the shore.
He saw Baron Friedrich von Schoenvorts and six of his men--all armed--while marching in a little knot among them were Olson, Brady, Sinclair, Wilson, and Whitely.
Bradley knew nothing of the disappearance of Bowen Tyler and Miss La Rue, nor of the perfidy of the Germans in shelling the fort and attempting to escape in the U-33; but he was in no way surprised at what he saw before him.
The little party came slowly onward, the prisoners staggering beneath heavy cans of oil, while Schwartz, one of the German noncommissioned officers cursed and beat them with a stick of wood, impartially. Von Schoenvorts walked in the rear of the column, encouraging Schwartz and laughing at the discomfiture of the Britishers. Dietz, Heinz, and Klatz also seemed to enjoy the entertainment immensely; but two of the men--Plesser and Hindle--marched with eyes straight to the front and with scowling faces.
