As one of the Harvard square cars was making its inward trip from Cambridge to Boston, Wednesday evening, an exciting scene occurred at the Boston & Albany Railroad crossing, Cambridgeport. The car, which was crowded with passengers, was not stopped in accordance with the law, and suddenly the horses got beyond the control of the driver, and made a dash forward. As a locomotive was approaching under a fair rate of speed, the gates, one on each side of the track, were closed across the street, but the horses dashed through the gate on the Cambridge side, tearing it from the hinges, and dragging the car after them. The car stopped exactly across the track. The engineer and fireman of the locomotive also saw the danger, and, reversing the steam and applying the brakes, they succeeded in stopping the engine, but not till it had approached to within four feet of the car. In the mean time the horses had continued unmanageable, and finally the leaders broke away and ran. Other horses were sent from the stables, and, after quiet had been restored, the car proceeded on its way.
