It shall constitute a misdemeanor for any stock rancher, as defined in this act, having charge of horses or other stock to herd, move, drive, or range the same or permit or suffer them to be herded, moved, driven, or ranged on the land or possessory claims of another person. Proof that such stock rancher did herd, move, or range such stock on such land or possessory rights is prima facie evidence of guilt, unless the evidence produced on the trial shows that the accused acted diligently and in good faith and with an innocent purpose to prevent such trespassing.
