To address a meeting in Glasgow gives one a feeling of pleasure; but, before going further, I trust that when I have finished you may not be able to say of me, as the two Highlanders did after leaving church--"Eh, man! wasna that a grand discoorse?--it jumbled the head and confused the understanding!" This city has brought forth one of the greatest of men--though, like many others, he had to fight an uphill battle in his early career--that man was James Watt. But what a career was his! and what a benefit to all now living has proved the result of his perseverance, for to his genius are we mainly indebted for the manifold applications of the wondrous power of _Steam_! That word is enough; and the engines it now propels are a powerful testimony to the talent of the great man who brought this mighty power to bear on the vast machinery, not only of this great country, but of the whole world. Contrast, for one thing, the travelling facilities of Watt's early days with those we now possess through his persevering industry. Fourteen days was then the usual time for a journey from Glasgow to London, while at present it can be performed in a less number of hours. Railways! what have they not done! We see towns spring up in a few years where only a few cottages formerly stood, and wild glens transformed into fruitful valleys, by means of railways in their neighbourhood developing traffic and trade, and creating employment by placing them in communication with larger towns, and thus opening up new sources of material prosperity. Look at the magnitude of our railways. With respect to locomotives alone, in 1866 there were 8125 of these, and the work performed by them was the haulage of 6,000,000 trains a distance of 143,000,000 miles. As each engine possesses a draught-power equal to 450 horses, these 8125 locomotives consequently did the work of more than 3,500,000 horses, and as the average durability of a locomotive is computed to be about fifteen years, each will have in that time traversed nearly 300,000 miles! Then, again, there have to be replaced about 500 worn-out locomotives every year, at a cost for each of about £2500 to £3000, entailing an annual expenditure of nearly £1,500,000 sterling. All this money circulates for the country's benefit, keeping our iron, copper, and coal mines, our furnaces and our workshops, all at work, and our people well and usefully employed, and thus proving one of the greatest advantages of applied science and art to this country and the world at large. If it had not been for steam, this valuable Institution might not have been in existence, having for its chief objects the promotion of the growth and increasing the usefulness of the applied sciences.
