Whether this sudden change of aspect was the result of a determination by a minority of the rustlers not to let the execution take place, or whether by some miraculous means one of his own friends had succeeded in joining the organization, he could not determine, although he tried to sound the man in the mask when the others were busy with their horses. His only reply was a low hiss commanding silence.
