[2] "_Deodand._ By this is meant whatever personal chattel is the immediate occasion of the death of any reasonable creature: which is forfeited to the king, to be applied to pious uses, and distributed in alms by his high almoner; though formerly destined to a more superstitious purpose. * * * Wherever the thing is in motion, not only that part which immediately gives the wounds (as the wheel which runs over his body,) but all things which move with it and help to make the wound more dangerous, (as the cart and loading, which increase the pressure of the wheel) are forfeited."--_Blackstone, Book I, Chap. 8, XVI._ Recurring, however, to the accident of December 24, 1861, the numerous casualties in that case were due to the crushing of the rolling stock which was not strong enough to resist the shock of the sudden stop. Under these circumstances the light, short English carriages rode over each other and were broken to pieces; under similar circumstances the longer and heavier cars then in use in America would have "telescoped;" that is, the platforms between the cars would have been broken off and the forward end of each car riding slightly up on its broken coupling would have shot in over the floor of the car before it, sweeping away the studding and other light wood-work and crushing stoves, seats and passengers into one inextricable mass, until, if the momentum was sufficiently great, the several vehicles in the train would be enclosed in each other somewhat like the slides of a partially shut telescope. Crushing in other countries and telescoping in America were formerly the greatest, if not the worst, dangers to which travel by rail was liable. As respects crushing there is little to be said. It is a mere question of proportions,--resisting strength opposed to momentum. So long as trains go at great speed it is inevitable that they will occasionally be brought to a dead-stand by running upon unexpected obstacles. The simple wonder is that they do this so infrequently. When, however, now and again, they are thus brought to a dead-stand the safety of the passenger depends and can depend on nothing but the strength of the car in which he is sitting as measured by the force of the shock to which it is subjected. This matter has already been referred to in connection with the Shipton and Wollaston accidents,[3] the last of which was a significant reminder to all railroad managers that no matter how strongly or with how careful a regard to scientific principles cars may be constructed, just so long as they are made by human hands it is easy to load on weight sufficient, when combined with only a moderate momentum, to crush them into splinters.
