“This Committee,” said Mr. Beckett, “have been told that, by the mechanical effects of smoke upon the chest and lungs, disease takes place; that is, by swallowing a certain quantity of smoke the respiratory organs are injured; can you give any opinion upon that?”—“One would conceive,” replied the Professor, “that that is the case; but when we compare the health of London with that of any other town or place where they are comparatively free or quite free from smoke, we do not find that difference which we should expect in regard to health.”

Mr. E. Solly, lecturer on chemistry at the Royal Institution, expressed his opinion of the effect of smoke upon the health of towns:—

“My impression is,” he said, “that it produces decided evil in two or three ways: first, mechanically; the solid black carbonaceous matter produces a great deal of disease; it occasions dirt amongst the lower orders, and, if they will not take pains to remove it, it engenders disease. If we could do away the smoke nuisance, I believe a great deal of that disease would be put an end to. But there is another point, and that is, the bad effects produced by the gases, sulphurous acid and other compounds of that nature, which are given out. If we do away with smoke, we shall still have those gases; and I have no doubt that those gases produce a great part of the disease that is produced by smoke.”

On the other hand Dr. Reid thought that smoke was more injurious from the dirt it created than from causing impurity in the atmosphere, although “it was obvious enough that the inspiration of a sooty atmosphere must be injurious to persons of a delicate constitution.” Dr. Ure pronounced smoke, in the common sense of visible black smoke, unwholesome, but “not so eminently as the French imagine.”

Many witnesses stated their conviction that where poor people resided amongst smoke, they felt it impossible to preserve cleanliness in their persons or their dwellings, and that made them careless of their homes and indifferent to a decency of appearance, so that the public-house, and places where cleanliness and propriety were in no great estimation, became places of frequent resort, on the plain principle that if a man’s home were uncomfortable, he was not likely to stay in it.

“I think,” said Mr. Booth, “one great effect of the evil of smoke is upon the dwellings of the poor; it renders them less attentive to their personal appearance, and, in consequence, to their social condition.”

It was also stated that there were “certain districts inhabited by the poor, where they will not hang out their clothes to be cleansed; they say it is of no use to do it, they will become dirty as before, and consequently they do not have their clothes washed.” The districts specified as presenting this characteristic are St. George’s-in-the East and the neighbourhood of Old-street, St. Luke’s.

It must not be lost sight of, that whatever evils, moral or physical, without regarding merely pecuniary losses, are inflicted by the excess of smoke, they fall upon the poor, and almost solely on the poor. It is the poor who must reside, as was said, and with a literality not often applicable to popular phrases, “in the thick of it,” and consequently there must either be increased washing or increased dirt.

To effect the mitigation of the nuisance of smoke, two points were considered:—

A. The substitution of some other material, containing less bituminous matter, for the “Newcastle coal.”
