At the entrance to the temple Ko-tan had relinquished the guidance of the guest to Lu-don and now the latter led Tarzan through those portions of the temple that he wished him to see. He showed him the great room where the votive offerings were kept, gifts from the barbaric chiefs of Pal-ul-don and from their followers. These things ranged in value from presents of dried fruits to massive vessels of beaten gold, so that in the great main storeroom and its connecting chambers and corridors was an accumulation of wealth that amazed even the eyes of the owner of the secret of the treasure vaults of Opar. Moving to and fro throughout the temple were sleek black Waz-don slaves, fruits of the Ho-don raids upon the villages of their less civilized neighbors. As they passed the barred entrance to a dim corridor, Tarzan saw within a great company of pithecanthropi of all ages and of both sexes, Ho-don as well as Waz-don, the majority of them squatted upon the stone floor in attitudes of utter dejection while some paced back and forth, their features stamped with the despair of utter hopelessness. "And who are these who lie here thus unhappily?" he asked of Lu-don. It was the first question that he had put to the high priest since entering the temple, and instantly he regretted that he had asked it, for Lu-don turned upon him a face upon which the expression of suspicion was but thinly veiled. "Who should know better than the son of Jad-ben-Otho?" he retorted. "The questions of Dor-ul-Otho are not with impunity answered with other questions," said the ape-man quietly, "and it may interest Lu-don, the high priest, to know that the blood of a false priest upon the altar of his temple is not displeasing in the eyes of Jad-ben-Otho." Lu-don paled as he answered Tarzan's question. "They are the offerings whose blood must refresh the eastern altars as the sun returns to your father at the day's end." "And who told you," asked Tarzan, "that Jad-ben-Otho was pleased that his people were slain upon his altars? What if you were mistaken?" "Then countless thousands have died in vain," replied Lu-don. Ko-tan and the surrounding warriors and priests were listening attentively to the dialogue. Some of the poor victims behind the barred gateway had heard and rising, pressed close to the barrier through which one was conducted just before sunset each day, never to return. "Liberate them!" cried Tarzan with a wave of his hand toward the imprisoned victims of a cruel superstition, "for I can tell you in the name of Jad-ben-Otho that you are mistaken." 10 The Forbidden Garden Lu-don paled. "It is sacrilege," he cried; "for countless ages have the priests of the Great God offered each night a life to the spirit of Jad-ben-Otho as it returned below the western horizon to its master, and never has the Great God given sign that he was displeased."
