Complete as we have shown the organization of the Arsenal to be, both as regards its mechanical resources and its staff, it is generally understood that the Government do not intend to depend upon it wholly for the supply of the munitions of war. In the case of small-arms, its powers, as we have seen, are wholly inadequate to the task. In those branches, however, where the manufacturing power is ample, they will not attempt to push it to the point of excluding the private manufacturer from a share in the business. This is, we think, a wise decision; for, however excellent may be the present arrangements now everything is new and the broom is fresh, it cannot be denied that the tendency of this and all other Government establishments is to go to sleep, since they neither possess the stimulus of private gain to teach them economy, nor that unity of direction which gives such vigour to private enterprises. The principle of competition ought therefore to be kept up, and we should run the private manufacturer against the public one in order to keep down price, and pit the Royal Factory against the trade in order to keep up quality. Another great gain will accrue from the determination of the Government, which is, that the private manufacturers will not lose the art of making certain stores of war--an art which can not be learned in a day. It would be unwise for the authorities to put all their eggs into one basket, and this they would most assuredly do by entirely depending upon their own powers of production, and in disassociating themselves from the great and fertile manufacturing power of England, which generally knows so well how to economize and progress.
