JAMES RADLEY'S NEW AND IMPROVED SPARK-ARRESTER, SPARK-ARRESTER. ANSWERS EITHER FOR WOOD OR COAL BURNING ENGINES. A large number have been running for a year past on Engines of the Baltimore and Ohio, Galveston, Houston and Henderson, Galveston, Houston and San Antonio, Houston and Great Northern, and more recently on the Louisville and Nashville Railroads. The Pipe has proved itself the most perfect Spark Arrester known: 1st-As perfectly safe from throwing fire; 2d-The escaping smoke and steam are driven out with great force above the top of the cars and clear of the train, thus keeping the cars free from cinders and smoke; 3d-Its steaming qualities cannot be excelled. By reference to the Cut, it will be seen that the area of the opening of the wire cloth is more than three times that of the opening at the top of the pipe, thus insuring a freer exhaust than in other pipes.
