FiEiKG OF Sawdust and Shavings.—The air was forcedinto the furnace with the planer shavings at a velocity of about12 feet per second, and at an average temperature of about GOdegrees Fahrenheit. The shavings were forced through a pipe12 inches in diameter, above grate, into the combustion pipe had a blast gate to regulate the air in order to main-tain a pressure in the furnace, which a little more than bal-anced the ascending gases in the funnel or chimney. Allthe fireman had to do was to keep the furnace doors closed andAvatch. the water in the gauges of his boiler. The combustionin the furnace was complete, as no smoke was visible. Theshavings were forced into the combustion chamber in a spray-like manner, and were caught into a blaze the moment theyentered. The oxygen of the air so forced into the furnacealong with the shavings gave full support to the combustion. u Maxims and FIRING WITH VARIOUS FUELS. The amount of shavings consumed by being thus forced intothe furnace was about fifty per cent, less than the amountconsumed when the fireman had to throw them in with hisshovel. It is an important pointwhen burning shavings or saw-dust with a blast, to keep theblower going without c( ssation,as there have been disastrousaccidents caused by the flamesgoing up the shutes, thencethroiioh the small dust tubesleading fr^ra the bin to thevarious machines. In firing shavings by hand it is necessary to burnthem from the top as otherwise the fire and heat are only pro-duced when all the shavings are charred. To do this, providea half-inch gas pipe, to be used as a light poker; light theshaving fire, and when nearly burned take the half-inch pipeand divide the burning shavings through the middle, banking them against the side-walls, asshown in Fig. 9
