Rufus Wheeler Peckham, Northern Pacific Company v. Egeland…
“ The act of jumping under such circumstances cannot, with any regard to common sense, be regarded as of the same obviously dangerous character, and to as great an extent, as that of riding on the pilot of an engine. If plaintiff reasonably though he could with safety obey the order by taking care and jumping carefully, and if, because of the order, he did jump, the jury ought to be at liberty to say whether, under such circumstances, he was or was not guilty of negligence. ”
