Zoanthrohago bowed. "And now," he said, "to the discussion of our experiments, which we hope will reveal a method for increasing the stature of our warriors when they go forth to battle with our enemies, and of reducing them to normal size once more when they return." "I hate the mention of battles," cried the king, with a shudder. "But we must be prepared to win them when they are forced upon us," suggested Zoanthrohago. "I suppose so," assented the king; "but once we perfect this method of ours we shall need but a few warriors and the rest may be turned to peaceful and useful occupations. However, go on with the discussion." Zoanthrohago concealed a smile, and rising, walked around the end of the table and stopped beside the ape-man. "Here," he said, placing a finger at the base of Tarzan's skull, "there lies, as you know, a small, oval, reddish gray body containing a liquid which influences the growth of tissues and organs. It long ago occurred to me that interference with the normal functioning of this gland would alter the growth of the subject to which it belonged. I experimented with small rodents and achieved remarkable results; but the thing I wished to accomplish, the increase of man's stature I have been unable to achieve. I have tried many methods and some day I shall discover the right one. I think I am on the right track, and that it is merely now a matter of experimentation. You know that stroking your face lightly with a smooth bit of stone produces a pleasurable sensation. Apply the same stone to the same face in the same manner, but with greatly increased force and you produce a diametrically opposite sensation. Rub the stone slowly across the face and back again many times, and then repeat the same motion rapidly for the same number of times and you will discover that the results are quite different. I am that close to a solution; I have the correct method but not quite, as yet, the correct application. I can reduce creatures in size, but I cannot enlarge them; and although I can reduce them with great ease, I cannot determine the period or endurance of their reduction. In some cases, subjects have not regained their normal size under thirty-nine moons, and in others, they have done so in as short a period as three moons. There have been cases where normal stature was regained gradually during a period of seven suns, and others where the subject passed suddenly from a reduced size to normal size in less than a hundred heart-beats; this latter phenomenon being always accompanied by fainting and unconsciousness when it occurred during waking hours."
