On Saturday morn., a sad accident occurred in Webster & Knowlton's saw mill at Cambridge Corner, near Berwick, N.S. A young man named Charles WEBSTER, the only son of the senior proprietor, while adjusting a belting, got the belt wound around his right arm. Before the machinery could be stopped, the unfortunate fellow was revolved around the shafting several times. He lingered two hours when death terminated his sufferings.
