THE DUST NUISANCE.

The dost niusance is a veritable nuisance in every town in New Zealand, and from time to time there ia much talking and writing, concerning tbe need for dealing with it, and concerning tbe best means to that end. Bat. the nuid&nce is more persistent than the talk or the efforts to overcome U, for it is never overcome, bat remains | a nuisance for ever. Still, there have of late been advances in tbe methods of at least modifying the evil, and it would appear that tbe most satisfactory consists in a machine which is known as the "Tarspray," which won tbe fisrt prize in a competition carried out in London some time ago under tbe encouragement of the Royal Automobile Society. The Melbourne City Council recently gave £250 for one of these machines, and it seems that it is pleased with its bargain. Essentially, tbe machine consists in a tartank, a small boiler to keep the tar jiquified, and a force pump with wbieb It ifl sprayed on to the roadway. Tbe pump, being worked from tbe wheels by chain gearing, comes into action only when the machine is moving, though arrangements are made for shutting off tbe spray, if necessary. The supply on any given area is practically constant under all conditions, for should tbe horse pulling tbe machine travel fast,- tbe volume of tbe spray will be proportionately increased; and, on tbe contrary, if be travels slowly, the volume will be similarly reduced. A Ceature of tbe tarspray is tbe bigb pressure at which the tar is delivered —between 751bs and lOOlbs to the square inch. Leaving tbe spraying nozzle with great force, and in a highly "atomised" state, therefore, it penetrates beneath tbe surface instead of lying about in pools, as it does under tbe old method. It is thus rendered not only less objectionable to pedestrians, but tbe result is a large saving both in time and tar.
