The thing had been very cunningly wrought from a single block of wood, very probably a section of a tree, upon which the features had been carved and afterward the interior hollowed out until only a comparatively thin shell remained. Two-semicircular notches had been rounded out from opposite sides of the lower edge. These fitted snugly over his shoulders, aprons of wood extending downward a few inches upon his chest and back. From these aprons hung long tassels or switches of hair tapering from the outer edges toward the center which reached below the bottom of his torso. It required but the most cursory examination to indicate to the ape-man that these ornaments consisted of human scalps, taken, doubtless, from the heads of the sacrifices upon the eastern altars. The headdress itself had been carved to depict in formal design a hideous face that suggested both man and GRYF. There were the three white horns, the yellow face with the blue bands encircling the eyes and the red hood which took the form of the posterior and anterior aprons. As Tarzan sat within the concealing foliage of the shrubbery meditating upon the hideous priest-mask which he held in his hands he became aware that he was not alone in the garden. He sensed another presence and presently his trained ears detected the slow approach of naked feet across the sward. At first he suspected that it might be one stealthily searching the Forbidden Garden for him but a little later the figure came within the limited area of his vision which was circumscribed by stems and foliage and flowers. He saw then that it was the princess O-lo-a and that she was alone and walking with bowed head as though in meditation--sorrowful meditation for there were traces of tears upon her lids. Shortly after his ears warned him that others had entered the garden--men they were and their footsteps proclaimed that they walked neither slowly nor meditatively. They came directly toward the princess and when Tarzan could see them he discovered that both were priests. "O-lo-a, Princess of Pal-ul-don," said one, addressing her, "the stranger who told us that he was the son of Jad-ben-Otho has but just fled from the wrath of Lu-don, the high priest, who exposed him and all his wicked blasphemy. The temple, and the palace, and the city are being searched and we have been sent to search the Forbidden Garden, since Ko-tan, the king, said that only this morning he found him here, though how he passed the guards he could not guess." "He is not here," said O-lo-a. "I have been in the garden for some time and have seen nor heard no other than myself. However, search it if you will." "No," said the priest who had before spoken, "it is not necessary since he could not have entered without your knowledge and the connivance of the guards, and even had he, the priest who preceded us must have seen him." "What priest?" asked O-lo-a. "One passed the guards shortly before us," explained the man.
