The bituminous Coal Smoke seems to be particularly annoying to the Pittsburgers a1 the present time, the damp atmosphere having condensed the immense clouds of smoke constantly thrown out by the numerous factories of the city, and caused it to descend in showers oi sooty flakes, rendering the city more than usually uncomfortable. The Gazette is agitating the institution of a commission by the City Council to inquire into the subject of remedying the trouble by causing the consumption of the coal smoke. We think the sooner the people oi Pittsburg set about this, the better. The smoke is fine coal, suspended in the atmosphere—the volatile products of bituminous combustion. This smoke can be consumed in properly constructed furnaces and fire-places, and thus a saving of fuel will be effected, together with that greater blessing, a purer atmosphere.
