Captain Steinson thought that air would always have a bad effect if there were pyrites. Mr. Bunninq thought that whether the ventilators were of iron or of wood, if the heat had arrived at a certain point at which active combustion had taken place, ventilation must do harm of necessity, because it absolutely fed the flame and increased the combustion. Mr. Fotheegill said, that looking practically at this question, he thought that these ventilators, the size of which must necessarily be very small, could not reach the bulk of the cargo, and that the parts not reached would still be liable to spontaneous combustion. Mr. J. S. Mitcalfe said, he had particulars of about 150 ships which had been burnt at sea, and he believed there were only two amongst the number which were not ventilated. The others were either thoroughly ventilated, partially ventilated, or had the hatchways ventilated. Mr. Wallace said, it had been stated by one speaker that when the coal had been thoroughly ground to a fine powder, it was not liable to spontaneous combustion, although, doubtless, while being ground it had absorbed a large amount of oxygen. It appeared, also, that when the coal was in the condition known as "small," presenting a very large surface to oxidation, it was liable to spontaneous combustion. It was also in a condition of allowing a certain amount of air to circulate through it. He could not help thinking that Mr. Steavenson's suggestion of putting coal in air-tight bunkers might be effectual, because it would prevent more
