We have dwelt upon the picture because it combined mechanical with manual dexterity. A hammerman who might sit for one of Homer's blacksmith heroes, and machinery which effects in a few minutes what an army of such hammermen could not do. If our painters of mythological Vulcans and sprawling Satyrs want to display their powers over flesh and muscle, they may find something real and not vulgar among our iron factories. After seeing the operations of forging or of casting, we may take a walk round the shops of the turners and smiths. In some, Whitworth's beautiful self-acting machines are planing or polishing or boring holes, under charge of an intelligent boy; in others lathes are ranged round the walls, and a double row of vices down the centre of the long rooms. Solid masses of cast or forged metal are carved by the keen powerful lathe tools like so much box- wood, and long shavings of iron and steel sweep off as easily as deal shavings from a carpenter's plane. At the long row of vices the smiths are hammering and filing away with careful dexterity. No mean amount of judgment in addition to the long training needed for acquiring manual skill, is requisite before a man can be admitted into this army of skilled mechanics; for every locomotive contains many hundred pieces, each of which must be fitted as carefully as a watch. If we fairly contemplate the result of these labours, created by the inventive genius of a line of ingenious men, headed by Watt and Stephenson, these workshops are a more imposing sight than the most brilliant review of disciplined troops. It is not mere strength, dexterity, and obedience, upon which the locomotive builder calculates for the success of his design, but also upon the separate and combined intelligence of his army of mechanics. Considering that in annually increasing numbers, factories for the building of locomotive, of marine steam-engines, of iron ships, and of various kinds of machinery, are established in different parts of the kingdom, and that hence every year education becomes more needed, more valued, and more extended among this class of mechanics, it is impossible to doubt that the training, mental and moral, obtained in factories like those of Wolverton, Crewe, Derby, Swindon, and other railway shops, and in great private establishments like Whitworth's and Roberts' of Manchester, Maudslay and Field's of London, Ransome and May of Ipswich, Wilson of Leeds, and Stephenson of Newcastle, must produce by imitative inoculation a powerful effect on the national character. The time has passed when the best workmen were the most notorious drunkards; in all skilled trades self-respect has made progress.
