The design of water-tube boiler shown in these engravingsemploys straight tubes, connecting at the upper and lower endswith water spaces, and above the water considerable steam spaceis provided. The chambers and dome are of steel plate, rivetedand bolted together as indicated, aud the furnace is surroundedby the water bottom. The last-mentioned member, the tubes,the dome and smokestack constitute the whole of this simpleconstruction, which may be easily repaired. The tubes are expanded into the upper and lower tube outside course of tubes are down comers and a diaphragmseparates from the next row, which are steam-forming The Watson Radial Water-Tube Boiler, The furnace has a baffle plate, as shown in the sectional smoketube is attached to an internal flange of the uppertube sheet and it is also secured to the top flange of the dome. Such a boiler ought to be a rapid steamer, and it is stated thatone of them has shown a pressure of 150 pounds per square inchwith cold water in 15 minutes after the fire was lighted. Thegage showed steam pressure in eight minutes, and in 10 minutes10 pounds pressure was obtained, after which the blower assistedin bringing up the pressure. This is made possible by the smallamount of water in the boiler and the favorable disposition of theheating surface. The circulation is also favorable to this boiler has been severely tested, the firing having been heavy enough to burn anthracite coal at the rate of 60 pounds per squarefoot of grate per hour by using forced draft. It is stated thatsuch a rate has been kept up
