PREFACE.

THE PRACTICAL METAL-WORKER'S ASSISTANT, as, now presented to the public, possesses some very valuable and essential features not found in former editions, and which, it is believed, will render it even more useful in the future than it has been in the past, great as has been its popularity.

Dr. Percy's treatise on the Manufacture of Russian SheetIron and Professor Fesquet's treatises on the Manufacture of Malleable Iron Castings and Improvements in the Manufacture of Bessemer Steel, are one and all important, especially in this country, at the present moment, when a new era is opening upon us, under the beneficent and wise policy which gives some heed to our industries, and is producing such magnificent results. Under this policy, as is most evident, the various departments of the Iron and Steel manufacture are advancing with rapid strides towards such a position as, it is believed, must within two decades, if not sooner, place them at the head of those industries throughout the world. Not only in these, but in all of the other branches of metal working, must this volume prove an important aid to the practical workman.
