textbook. Basic description is attempted, and the bibliography has been specifically chosen to guide the reader toward a fuller treatment of his special ised interests. No fully satisfactory term has yet emerged to describe the processing of minerals, which is also called "ore dressing," "mineral dressing," "mineral engineering" and, in the University of London degree course "mineral technology." The dressing of ores was an excellent description of the older processes which aimed to break down rock to appropriate sizes, grade it, and separate the heavy fraction from the light one in each grade or size by gravity methods. The work done in the mill today goes far beyond these simple operations, and requires some knowledge of physical chemistry, particularly the branches which deal with the physics and chemistry of surfaces and of the interphase between solid particle and the surrounding liquid. At the same time, the engineer must not become so absorbed in the study of fundamental and applied technology as a physico-chemical science that he overlooks the mechanical, economic, and humanistic aspects oli his work. He is an engineer, a chemist, a physicist, and an administrator and, as such, should have a sound scientifj. c and cultural education. Technically, his work is to extract the valuable minerals from the ore sent to his mill; economically, it is to balance all the financial costs and returns in such a way as to ensure the maximum profit from the operation."

This book is intended both as a resource for engineers and as an introduction to the layman about our most important metal system. After an introduction that deals with the history and refining of iron and steel, the rest of the book examines their physical properties and metallurgy. To elaborate on the importance of iron and steel, we can refer to the fact that modern civilization as we know it would not be possible without it. Steel is essential in the machinery necessary for manufacturing that meets our needs. Even the words themselves have come to suggest strength. Phrases such as 'iron willed', 'iron fisted', 'iron clad', 'iron curtain' and 'pumping iron' imply strength. A 'steely glance' is a stern look. 'A heart of steel' refers to a very hard demeanor. The Russian dictator, Stalin (which means steel in Russian), chose the name to invoke fear in those under him.
