like paper. Every possible support that can be afforded by runners is given to the saw; still, with every aid, it is astonishing to see metal, which we have been taught to believe rigid, flexible as indiarubber. Adjoining are frame saws, working up and down by steam, and cutting half a dozen or more boards at the same time. It was in this department that the Queen's carriage was built at a great expenditure of skill and money--a carriage which is considered one of the masterpieces of this particular craft. There rises up in the mind, after the contemplation of this vast workshop, with its endless examples of human ingenuity, a conviction that safety in railway travelling is not only possible, but probable, and even now on the way to us. No one can behold the degree of excellence to which the art of manufacturing material has been brought, no one can inspect the processes by which the wheel, for instance, is finally welded into one compact mass, without a firm belief that, where so much has been done, in a little time still more will be done. That safer plans, that better designs, that closer compacted forms will arise seems as certain and assured a fact as that those forms now in use arose out of the rude beginnings of the past; for this great factory, both in its machine-tools and in its products, the wheels and rails and locomotives, is a standing proof of the development which goes on in the mind of man when brought constantly to bear upon one subject. As with the development of species, so it is with that of machinery: rude and more general forms first, finer and more specialized forms afterwards. There is every reason to hope, for this factory is a proof of the advance that has been made. It would seem that the capability of metal is practically infinite. But what an enormous amount of labour, what skill, and what complicated machinery must be first employed before what is in itself a very small result can be arrived at! In order that an individual may travel from London to Oxford, see what innumerable conditions have to be fulfilled. Three thousand men have to work night and day that we may merely seat ourselves and remain passive till our destination is reached.
