While there are few persons who can give a very clear account of the processes by which several of our commonest articles of utility are manufactured, there are a great num ber who desire to know something more about them. It is only necessary to listen to the remarks of the visitors at any Industrial Exhibition, to discover that there are a hundred scientific and mechanical problems which remain unsolved by several inquirers, who scarcely know where to look for information. This is so obviously the condition of the younger portion of such an assembly, that surely nothing but that fear of innovation which exercises so depressing an in?uence in many of our schools, would have prevented the use of some recognised work on this subject, as one of the ordinary read ing books. The present volume is a faithful record of a series of visits to some of the great workshops in various parts of the country. It would be impossible, within the compass of a single volume, to include a reliable account of one of each variety amongst the multitude of England's workshops, Â but it is believed that the manufactures here described are sufficiently various to be generally interesting, and the writers have endeavoured to present them in as popular a form as the nature of the subject would admit. It is of course not to be understood that all the manu factories mentioned here are represented as having a superior claim to others engaged in the same branches of industry, either as regards the extent of their operations, or the quality of the articles which they produce. To this there are a few well-known and important exceptions; but in the majority of instances the places were selected either because they were more accessible, or from other circumstances, which, at the time, made this selection desirable.
