About midnight
By noon we had passed the meadow of our night 's camp . After a hasty lunch we accompanied our men a few miles farther , then said farewell and godspeed , and hurried back in order to reach home before sunset . We cooked ourselves a meal , and built ourselves a fire . About midnight we heard the sounds of horses rapidly approaching . Immediately we leaped from our bunks and seized our rifles , peering anxiously into the darkness . A moment later , however , we were reassured by a shrill whistle peculiar to Buck Barry , and a moment later he and Don Gaspar rode into camp . We assailed them with a storm of questions -- why had they returned ?
