On t]te Influence of Pressure on C]temica1.4~nlt~j. 285 to Mr. WIn. Melbourn, of North Shields, was offered for the purpos% and a series of experiments were made upon the furnaces, the plan adopted being very simple, consisting of a proper admission of air into the furnace, which, combined with careful stoking, was expected to consume the smoke. After certain alterations were effected, the tug was taken to sea, with a party of steam-tug owners, and their solicitor, Mr. Kewney, and the inspector
... , and the inspector of nuisances, on board. It was found that the improvement effected was verygreat, upwards of 75 per cent. of the smoke being consumed, and the remainder being of a character far less offensive, being thin and light colored. The inspector considered that the result was very satisfi~ctory. Dr. Richardson and Mr. Reed were determined, however, to effect a perfect consumption of smoke, if possible; and made further alterations. On the 5th ult. the ]~'xpert proceeded to sea, on a voyage fi'om Newcastle to Warkworth, a distance of 30 miles, having on board Mr. Miller and Mr. Taplin, govermnent engineers (sent from Woolwieh and :Portsmouth to test the experilnents going on at Elswick to consume the smoke, with a view to re-introduce the Northern coM into the naval yards) ; and also Dr. Richardson and Mr. Reed, and a party of steamboat owners and their solicitor. It was found that the alterations, which were of a simple character and comparatively inexpensive, entirely effected the consumption of the smoke, there being none whatever visible throughout the voyage out or home, except when Mr. Reed, in order to exemplify the efficiency of the system, stopped the admission of the air, and allowed the production of the smoke at plea~sure~ or the entire consumption, as he thought fit. The other steam-tugs in the association, and the steam-ferries on the Tyne, will be fitted up with the apparatus forthwith, and it is anticipated that a great nuisance to the river and harbor towns of the Tyne, occasioned everysea-tide by a black fall of smoke hanging over them, and sometimes entirely obscuring the view of tl~e sea~ will be entirely removed.
