Book excerpt: Excerpt from The Manufacture of Carbons for Electric Lighting and Other Purposes Books and pamphlets abound upon most branches of electricity and allied subjects, but one notable exception is that of electric-light and electrolytic carbons, such as are extensively used in every civilised country of the world. It is true that "The Electrician" Printing and Publishing Company published, some years ago, a small pamphlet on the subject, but this simply related to the experiments that were made by a gentleman who was not engaged in practical business, but whose work will always find a place in the history of the development of the carbon industry. That so little has been written upon the subject of the manufacture of carbons, and that such a gap has existed for so long a time, is obviously due to the fact that very few have had a chance of thoroughly inspecting carbon works, which are usually as zealously guarded as a fortification. Carbon manufacturers have always been of the opinion that the less said upon the subject the better for them, and it is well known that the art of manufacturing high-grade carbons was always regarded as a sort of secret, of which a few only had the monopoly.
