ELLIOTT, BRIGHTON, MASS. shutting fire doors and allowing cold air to rush in over the fire, wasting coal and causing black smoke to is- sue from the stack. There are no fire doors, in fact, in the general ob- servance of the term, and only the requisite, steady amount of air neces- sary for the proper mixture is al- lowed to enter the fire chamber through the air ducts referred to. Be- sides this, air is admitted to the outlet or flue just above the boiler and this checks the suck or draught of the flue, preventing waste of fuel and con- sequently smoke. Now every green- houseman knows what a great nui- sance the chimney stack is when belching forth great clouds of smoke. This precipitates soot which falls upon the glass keeping out light and find- ing its way through the ventilators to damage the flowers. All this is pre- vented by the use of the Doylalr sys- tem, which has been thoroughly tested, not only on stationary plants, but on locomotive engines actually running, a train having been taken from the stock yards in Chicago to Argo and return, a distance of 25 miles, without any sight of smoke coming from the chimney and with practically no stoking. The little amount of skilled labor needed is, in fact, ona of the side is- sues where considerable saving is made , though even this, important as it is, cannot compare with the won- derful saving in fuel that is caused by the use of this device. The manufac- turers claim that they can show, by actual working tests, a saving of 50 per cent in coal when their system is installed and properly understood, and its working is so simple that any one can manage it. Furnaces equipped this way cost very little more than the ordinary boiler and take up less room per unit of heat produced. Then its great cleanliness and the small amount of ash made, even from coal of low quality a
