All the heating surfaces are below the water line,•which ensures safety to tlie boiler. The circulation of the vrater withiathe boiler is perfect, thus holding the sediment in suspension, so thatit may be expelled by blowing out The cylinder aud its pai-ts arekept hot by immersion in the steam, so that no caloric is lost, and th«^toA has a vertical movement, ^o that th«t« is but Uttle wear and MACHINISTS ENGINEERS DEPARTMENT, 439 tear resulting froin friction. It is hardly possible to explode theboiler in any contingency, and 100 lbs. of coel will nm a four-horseengine for 10 hours. The whole machine is composed of about 130component parts, all interchangeable, so that each article can be fur-nished by the manufacturer, as it may be required to effect r
