These tables are de-serving of the most careful study. Take the matter of speed first. At 40revolutions per minute the Mikado couldonly develop 1,320 horsepower on fullgear, with a steam consumption of hour, while with a 75 per cent, cut-offit developed 1,300 horsepower on a steamconsumption of about 25 lbs. per made it possible for the engineer tothrow away 25 per cent, of the necessarysteam with no results. The best resultsat 40 revolutions per minute with the Mi-kado were obtained when developing1,000 horsepower on a 50 per cent, cut-off and a steam consumption of lbs. : l|||i||||||||i|||||i|||| l« nj #,r.«..
