Smoke Dissipated.

The practical way to obviate the annoyance of smoke Is to dissipate it before it leaves the chimney top in a gaseous volume. A German professor believes he has found a way to secure this result without chemical or mechanical aid. Described In Die Umschau, the professor’s chimney Is perforated on all sides by what might be called little horizontal windows. As the furnace smoke and gases rise they are mixed with air, both before and after emergence, by the eddy forming action of the wind passing- through the openings, x From the time the smoke enters the chimney and reaches the height of the lower openings, which receive the wind from any quarter, the intermingling begins, and in each stage of Its upward movement the volume becomes less and less. At the mouth of the chimney the outpour is comparatively small and so diluted with air that only a sheet of dark blue smoke waving like. a flag to the leeward Is seen, where, under other conditions, there would be a cioudlike column of dense black smoke a mile long. Chimneys constructed on the professor’s plan look not unlike windowed towers.
