There ought to be no accidents from the breaking of railway carriage axles: such an occurrence as the breaking of an axle is an everlasting disgrace; for axles could be constructed that no known “fair application” of strain could possibly break. A simple combination of steel and iron faggoted in segments, as before described, and rolled hollow, would enable axles to last double the time of those at present in use: 40,000 miles travelling is stated to be the maximum distance an axle can be safely trusted; the destruction being mainly due to the heating in the journals, or to galvanic action changing the fibrous iron into crystalline in the immediate vicinity of the bearing. Axles constructed of different metals, as steel and iron in conjunction, would not be so affected; and might be rendered still less likely to be so by a small hollow in the centre of the axle. But this is a digression; though I may be pardoned for it, in consideration of the importance of the subject.
PLATE. II.
DAMASCUS BARRELED GUN
FANCY STEEL BARRELED GUN
The opposite [plate (No. 2)] represents my mixture in imitation of Damascus; the process necessary to produce it, as well as its companion, has already been described. These two also come under the head of best barrels, as they are costly, and when honestly made (not plated) constitute, with the defects before enumerated, good barrels.
The cost of a really good first-rate gun must and will always vary, according to the circumstances of manufacture or the peculiar arrangements of the manufacturer. Joseph Manton is entitled to the gratitude, not only of the present generation of gun-makers, but of all succeeding ones, for this reason,—he not only gave a character to English guns, but so linked his name with improvements, that it will never be forgotten. His was the mind to know and appreciate the value of good workmanship; he elevated the English artisan with himself, and raised the gunmaker to the acme of mechanical skill: for, without invidious comparison of the ability required in other professions, we may say that a first-rate workman as a gun-maker[11] (I mean only a gun-maker) is one of the very best mechanics England can boast of, or in truth any part of the world. Gun-making is the profession of a man of mind: any man or any workman cannot make a gun, working by square and rule entirely, as other mechanics do: no, the true gun-maker is an artist, and Joe Manton made him so.
[11] Barrel welders, borers, lock-filers, &c., are not technically gun-makers: the latter are those workmen who, having barrels, locks, wood for stock, &c., make them into a gun. It has been customary to say gunsmiths; but this appellation can be applied to the worker in iron only.
