In anyevent whenever an engine is designed to work with a verylew pressure in the receiver, it may even be desirable to in-crease the above two elements. Which among the diverse methods employed—all evidentlybeing of a nature to insure a free steaming locomotive—are those which at the same time give the most economic per-formance of the steam consumed?
