If we checkthe Mikados performance on a 50 percent, cut-off, it becomes 2,320 horsepoweron a steam consumption of lbs. perhorsepower hour, or 1 lb. less than thedecapod, but with a sacrifice of 1,380horsepower to effect the relative saving. These are but a few of the interestingitems that may be developed from thesetable-, which should be most carefullystudied.
