The following occurrence lately took place on the French Northern Railroad. It is an example of the advantage that sometimes arises from meeting opposition with a bold front: The passengers upon the Northern Railroad narrowly escaped destruction some days ago. A large cart, laden down by the weight of an enormous block of stone, had become fastened in among the rails, and 1;he efforts of the three horses to disengage it were perfectly unavailing. The whistle ot the express train was heard in the distance. The wagoner, determined to save his horses at least, cut the reins and the harness and made off. The engineer saw the obstacle, reversed the steam and gave the signal for the brakes. But the engine, which was a Crampton, refused to obey, and the machinist saw the utter impossibility of stopping it in time,o he put on the steam again, and drove the train with full force upon the terrible obstacle. The wagon was shivered to atoms, and the stone sent flying in splinters for rods in all directions. The train was not thrown off the track, and the passengers were unaware of any shock. Thsy did not hear of the danger they had run till they stopped at the next station. The engine was battered, but its vitality was not decreased. The engineer, whose coolness and decision saved the passengers, is a Pole, and will be bhe object of some tribute of gratitude from the company.
