ten o'clock
A little fire , some tea and bouillon -- made in the pan after the tea was consumed -- and the two boys found a bed on the soft sand with no covering but the deep Mexican sky . At dawn they were up and away after a bath in the muddy river . Elmer was now the guide and he readily picked up Buck 's old wagon trail . Sharp at ten o'clock a halt was made for breakfast , bouillon now without tea . Ned , his face a little more sunken and his legs a little more unsteady than the day before , was sitting on the ground resting his burning feet , when Elmer suddenly touched him on the shoulder , set the soup pan quickly on the sand and drew his revolver . Far down the trail a horseman was approaching . Behind him in the distance followed a wagon .
