'We were sneaking past Ashair without lights,' he said, 'on our way down river to capture a few slaves; but what in the world were you doing out here in the middle of Horus?'
'I was swimming to Ashair to steal a boat,' replied the ape-man.
'Are you crazy?' demanded Thetan. 'No man could hope to live in these waters. Why, they are alive with flesh eaters.'
'So I discovered, but I think I should have gotten through. I must have been half way across. It was not my life that was at stake, Thetan, but those of my friends who are prisoners in Ashair. I must reach Ashair and get a boat.'
Thetan thought for a moment; then he said, 'I'll take you. I can land you on the shore below the city, but I advise you to give up all thought of it. You cannot enter Ashair without being discovered, and that will be the end of you.'
'I don't want to go ashore,' replied Tarzan. 'I have two companions across the lake from the city. If you will take the three of us to a point above the temple of Brulor , I won't have to go ashore and steal a boat.'
'What good will that do you?' demanded Thetan.
'We have water suits and helmets. We are going into the temple to get our friends, and I've got to take Brulor and The Father of Diamonds to Herat to get him to release Magra and Gregory.'
'They've already escaped,' said Thetan, 'and Herat is furious.' He did not say that he had helped them, as other Thobotian warriors were listening.
'That really doesn't make much difference,' said Tarzan. 'We can't escape from Tuen-Baka without Herat 's aid. We'll need a galley and provisions. If I bring Brulor and The Father of Diamonds to him, he'll give us what we need, I'm sure.'
'Yes,' agreed Thetan, 'but you won't ever bring Brulor and The Father of Diamonds to Herat . What chance have you, practically unaided, to do what we have been trying to do for years?'
Tarzan shrugged. 'I still must try,' he said. 'Will you help me?'
'If I can't dissuade you, I'll help you. Where are your friends?'
Tarzan pointed in the general direction of the cave where he had left Helen and Herkuf, the torch was extinguished, and the galley's nose turned toward the shore.
From the quay at Ashair, six galleys put out without lights into the darkness of the night to search for the quarry, which they could no longer see since the torch had been extinguished; and as they rowed from shore, they fanned out, some up river, some down, to cover the most territory in their search.
The shore line ahead of the galley bearing Tarzan was a long, black silhouette against the night sky. No landmarks were visible; and the shore was a straight, black line without breaks or indentations. Only the merest chance might bring them to the spot where Helen and Herkuf waited. When they were quite close to shore, Tarzan called Herkufs name in a low voice; and immediately there came an answering hail from their right. A few minutes later the keel of the galley touched gravel a few yards from shore, and Tarzan leaped out and waded to where Helen and Herkuf stood. They were amazed that he had returned so soon, amazed that he had returned at all, for they had seen the torchlit galley and believed that he had been captured by Asharians.
Briefly he explained what had occurred; and, telling Herkuf to follow with the water suits and helmets and weapons, he tossed Helen to a shoulder and waded back to the galley, which turned its nose toward Ashair as soon as Herkuf was aboard. Tarzan, Helen, and Herkuf immediately donned their water suits, leaving their helmets off, temporarily, so that they could talk.
Silently, the galley glided out into the lake, the oars dipping without noise as they were plied by thirty well trained slaves, who had learned by long experience the necessity for stealth in passing through the lower waters of Horus where Asharian galleys might be lying in wait for them—Asharian galleys and Asharian warriors who might send them to the bottom chained to their thwarts. About mid-lake a torch suddenly burst into flame to the right of them; then another to the left, and in quick succession four more between them, forming a semi-circle toward the center of which they were moving. With the lighting of the torches, a loud Asharian war cry broke the deathly stillness of the night; and the Asharian galleys moved to encircle that of Thetan.
Nothing but immediate flight might save the Thobo-tians; and as the prow of the galley turned quickly toward the lower end of the lake in an effort to elude the jaws of the closing circle of enemy galleys, Tarzan called to Helen and Herkuf to don their helmets as he adjusted his own; then, seizing Helen's hand and signalling Herkuf to follow, he leaped overboard with the girl, while Thetan urged his slaves to greater speed.
Chapter 29
HAND IN HAND, Tarzan and Helen sank gently down to the darkness of the lake's bottom. If Herkuf were near them, they could see nothing of him; and so Tarzan waited for the coming of the new day that would lift the black veil from the mysteries of Horus's depths, as to proceed without Herkuf might easily foredoom the entire venture to failure. That they might never find him, Tarzan was aware; but he could only wait and hope.
It was an eerie experience for Helen Gregory that was rendered doubly trying by the recollection of her previous experiences in this silent world of horrors. Dimly seen, great forms glided through the forest of grotesque treelike plants that waved their dark foliage on every hand. Momentarily, the girl expected some hideous monster to attack; but the night passed and dawn broke without their having once been threatened. It seemed a miracle to her, but the explanation probably lay in the fact that they had remained quietly sitting on the gravelly bottom. Had they been moving, it might have been different.
As the light of the new day filtered down to them, Tarzan looked about for Herkuf; but he was nowhere to be seen. Reluctantly, the ape-man started off across the lake toward the temple of Brulor . What he could accomplish alone, he did not know, as part of the plan was to enter the temple during a period of meditation and release the prisoners; but of the three, only Herkuf was familiar with the mechanism that operated the doors to the air chamber and emptied and refilled it; only Herkuf knew the exact time of the periods of meditation.
Unable to communicate with Tarzan, Helen followed where he led, ignorant of his new plans but more secure in her faith in him than he was of himself in this particular venture, where every condition varied so from all that he had been accustomed to meet in the familiar jungles that he knew so well.
They had gone but a short distance in the direction in which Tarzan thought the temple lay, when they came upon Herkuf. He, too, had been waiting for daylight, feeling certain that Tarzan would have done the same and that, having leaped overboard almost simultaneously, they could not be far separated. It was with feelings of the greatest relief that they found themselves reunited.
Herkuf took the lead now, and with Tarzan and Helen following, commenced the tiresome and dangerous journey toward Ashair, all of them now greatly encouraged after the long hours of doubt and uncertainty.
They had not gone far when they came upon the wreck of a large galley partly embedded in the sand. That it had been there for years was attested by the size of the marine growth which had sprouted through its ribs, entwining the skeletons of its slaves still lying in their rusted chains.
Herkuf evinced considerable excitement; and, motioning them to wait, clambered into the interior of the craft, from which he presently emerged carrying a splendid jeweled casket. That he was overcome by excitement was obvious, but hampered by his helmet he could only express it by waving the casket before their faces and dancing jubilantly. What it was he had recovered, they could not guess, unless it were that the casket contained treasure of fabulous worth.
At last, and without further adventure, they approached the temple of Brulor; and here they went cautiously, seeking the shelter of the trees and plants that grew in the gardens of the ptomes, moving stealthily from one to another, each time assuring themselves that no ptome was in sight, knowing that at any moment one might emerge from the air chamber that they could now see. Approaching the temple, they found a place where they could hide concealed from the gardens and the air chamber door. Here they must wait until Herkuf signalled that the time had arrived when it might be safe to enter the temple. How long that would be only he could guess with any degree of accuracy. Near them was a window through which they could have looked into the temple had they dared; but as long as it was light outside they could not take the risk; and so they waited, tired, hungry, and thirsty; waited for night to fall.
Inside the temple the caged prisoners were gnawing on their evening meal of raw fish. Atan Thome enlarged
