From the book:If you open your mouth again, I'll drive my fist down your throat! The young man, or boy rather, - for he was not yet eighteen years old, - who made this very emphatic remark, was a stalwart, well-built youth, lithe of limb, elastic in movement, slender, straight, tall, with a rather thin face, upon which there was as yet no trace of coming beard, high cheek bones, and eyes that seemed almost to emit sparks of fire as their lids snapped rapidly together. He spoke in a low tone, without a sign of anger in his voice, but with a look of earnestness which must have convinced the person to whom he addressed his not very suave remark, that he really meant to do precisely what he threatened. As he spoke he laid his left hand upon the other's shoulder, and placed his face as near to his companion's as was possible without bringing their noses into actual contact; but he neither clenched nor shook his fist. Persons who mention weapons which they really have made up their minds to use, do not display them in a threatening manner. That is the device of bullies who think to frighten their adversaries by the threatening exhibition as they do by their threatening words. Sam Hardwicke was not a bully, and he did not wish to frighten anybody.
