These were fixed to a sole-plateat the top of the chimney 12 feet abovethe furnace and used as exhausters. Theash-pit doors being open, it was found thatthe in-draft at the furnace doors wasonly .25-inch water gage. The power ofthe furnace was considerably less than inthe other experiments, although using fourtimes the quantity of steam. The resultwas anticipated, but the experiment was.

The first experiment was with a Kort-ing steam-jet blower, the initial nozzlebeing .25 inch diameter, which gave apressure of .20 inch water gage. Thesecond experiment was with a small high-speed engine geared direct to a Sturte-vant centrifugal blower, and by using ex-actly the same weight of steam the pres-sure was increased to .60 inch. In thesetwo experiments the furnace gases passedthrough a multitubular boiler 10 feet longand 6 feet diameter to a stack which was40 feet high above the grate. Two otherexperiments were afterwards made with-out the boiler and the furnace gases passeddirect to a special chimney 12 feet highover the furnace, and it was found that■with the same blast pressure the incinerat- raade to convin
