four o'clock
Thus the youth of Wallencamp , yes , and those who heeded not the swift decline of years , by reason of the immortal freshness of their spirits , disported themselves . And I was not amazed , catching a glimpse through the school-house windows of this joyous boat on one of her return voyages up the lane , to see Grandma Keeler swaying wildly in the stern . Meanwhile , I managed to keep my flock indoors . But when , at four o'clock , I took my ruler in hand to give the usual signal of dismissal , the Phenomenon 's heels had already vanished through the window , and the repressed animal spirits of a whole barbaric epoch sounded in the whoop with which the Modoc shot through the door . Finally , I , myself , rode up the lane in the boat . The path was well worn by this time , and there was no danger of a catastrophe . It seemed to me a novel performance enough , but I had not yet been to ride in Lovell 's sleigh .
