No man has more occasion to bless the introduction of the steam-engine, machinery, the galvanic battery, and science in general, than the working mechanic, because it has mitigated his physical toil by giving him the duty of simply directing the labour instead of actually performing it; whilst it has deprived him of one kind of employment it has provided him with something better. But a few years ago the operatives in the silver-plating trade had to lay the silver on the articles with their hands, with the aid of a soldering iron; now they have simply to set their batteries in action and watch the electricity doing it for them. In a similar manner the working engineer at his metal-turning lathe has merely to direct the action of his tools whilst the steam-engine performs the heavy labour of turning. There is not a man in this kingdom who has not derived some advantage, in one way or another, from scientific research. The advantages of gas light, electric light, rapid postal service and transmission of goods, railway travelling, steam-ships for navigation, cotton apparel, photography, cheap pottery, improved medicine and surgery, telegraphic forecasts of weather, Australian preserved meats, &c., &c., have been reaped more or less by everyone, even the very paupers. Not only has travelling been {36} considerably cheapened and immensely increased, but also rendered more safe:--in travelling by diligence in France the average number of persons injured was 1 to every 30,000 carried; and killed, 1 in every 335,000; but by railway, notwithstanding the average length of the journey has greatly increased, the former has been diminished to 1 in 580,000, and the latter to one in five millions; safety in travelling by sea has also been greatly increased by means of improved lighthouses. By the rapid transmission of messages by telegraphs and of commodities by steam-ships and railways, the horrors of famine have been largely diminished; the health of this nation has also been improved by greater variety of foods, and the increasing cost of meat has been restrained. It is well known that in periods of famine, the great loss of life has arisen, not from universal scarcity of food, but from the loss of time in ordering and conveying it. Whilst also the steam-engine has been the means of relieving hundreds of thousands of men from mere animal toil; it has, with the aid of the printing-press, supplied them with cheap daily intelligence.
