Prime among the features that we. O 68 THE LOCOMOTIVE. [July, retain under all circumstances is the provision, under some form or other, for thecooling of the columns that support the beams from which the boilers are sus-pended, as will presently be explained in detail. Fig. i shows a front elevation of several horizontal tubular boilers, withportions of the settings in section. Heavy I-beams pass across the battery, over-head, and from these beams hangers pass down to the boilers, as shown. TheI-beams from which the boilers are suspended rest, at their ends, upon columnsof cast or wrought iron, which transfer the weight directly to the foundation ofthe setting. At the outside wall of each battery thus fitted up, the iron support-ing columns are built into the brickwork of the setting, in such a way that theirouter surfaces come flush with the outer face of the setting wall. The brick-work of the setting comes solidly into contact with these outside columns, andgives them lateral support. The outside
