The Smoke Nuisance.

An invention, which seems destined in a. remarkable degree to load to the mitigation of what is popularly known • as the Bmoke nuisance, was (says the Sydney Morning Herald of May 20th) on Saturday afternoon exhibited at work on board the steamship Narrabeen in the presence of a consider-' able number of gentlemen who take an interest in scientific matter. Tile invention is'known as Don's' Smoke Preventor - and Fuel Economisor,' lor which it is stated that no ■ fewer ■ than thirty-six' patents have been obtained- % in 'various countries The instrument is nothing • more than an air injector fitted above'fla ; door ot each furnace! and. Bon&f trived that it aucks the air from tlio atmosphere, • and delivers it wiC'' greatjorce on the : surface of the fi K> The effect of this- is to drive w atoms of oxygen into contact with the atoms of hydrogen and, earbon-' the instant they are born, the result being visible flame. By this chemical union, not only is the flowoi volumes of denso smoke charged with smut prevonted, but the furnace is kept at a much more even' temperature than under ordinary- con.'" ditions, and a saving of fuel is effeo- "< teil which is represented as being so great that with the new smoko preventer in use less than £9O-worth ■■■ of coal will generate a volume ; of steam equal to that for the production of which under ordinary conditions the consumption costs £IOO, ■ Four of Don's injectors were used on Saturday, one being applied to each, furnace., The Narrabeen first proceeded as far asCobkatoo Island, • thence she made atrip to and back to the Circular time occupied in steaming being two hours and a half and the vessel doing " about ten knots an honr.
