midnight
A heavy war spear which he sometimes carried in one hand and again slung by a thong about his neck so that it hung down his back completed his armament and his apparel . The diamond-studded locket with the pictures of his mother and father that he had worn always until he had given it as a token of his highest devotion to Jane Clayton before their marriage was missing . She always had worn it since , but it had not been upon her body when he found her slain in her boudoir , so that now his quest for vengeance included also a quest for the stolen trinket . Toward midnight Tarzan commenced to feel the physical strain of his long hours of travel and to realize that even muscles such as his had their limitations . His pursuit of the murderers had not been characterized by excessive speed ; but rather more in keeping with his mental attitude , which was marked by a dogged determination to require from the Germans more than an eye for an eye and more than a tooth for a tooth , the element of time entering but slightly into his calculations . Inwardly as well as outwardly Tarzan had reverted to beast and in the lives of beasts , time , as a measurable aspect of duration , has no meaning . The beast is actively interested only in NOW , and as it is always NOW and always shall be , there is an eternity of time for the accomplishment of objects .
