As a train was proceeding at express rate along the London- nd Northwestern Railway on the 10th of May last, the engine driver perceived a cow upon the road; he shut off steam, applied the brakes, but could not stop before the cow was entangled in the wheels of the engine, all the Cars were thrown off the rails, and three passengers were killed. There was evidence to show that the persons in charge of the train had acted with wonderful presence of mind at the moment of the occurrence, and a gate-keeper was engaged trying to drive off the cow. Had the English locomotive been provided with an American cowcatcher this accident would not have occurred.
