ADDENDA.
ANTHRACITE COAL BURNERS.
For anthracite coal, a long and shallow fire-box is constructed, and the back driving-wheels are placed at the same distance from the main pair as the latter are from the front drivers. This reduces the rigid wheel-base to some extent, but retains the same weight on drivers.
