MANY kinds of marcasite* are found since every metallic mineral, and perhaps some of the semiminerals, produces its own. I believe that [28v] rnarcasites are nothing other than the secondary materials and the menses of the conception of metals which, through insufficient time, have yet to arrive at their perfect age; and thus, because of

The present and future activity of western coking coals is discussed. A general description of location, quantity, and quality is used as a basis for discussing development, mining, and marketing problems facing these reserves. As the need for coke from the West increases, solutions to the present mining and transportation problems will be forthcoming. Improved mining and blending technology, coupled with a more economical transportation solution, must precede a rapid development of the West's coke reserves. Ever increasing demands on coke production enhance the prospects of an accelerated development of these reserves.

OUR citizenry must comprehend the cold, fundamental, economic truth that the ability to create wealth depends upon primary wealth; that only primary wealth can insure our economy, liquidation of our debts, national solvency, national security.

H. M. HOWE, Bedford Hills, N. Y.-We may clear the matter very easily, at least to a very great extent, if we look at these islands of ferrite that occur in steel castings as simply corresponding to the ferrite ghosts in steel forgings, representing the differentiation that takes place in the solidification off the molten mass. In that solidification you have dendritic crystals forming and in between those dendrites you have con-

THE wave of nationalism co-mingled with communism which is sweeping from the Philippines across the Asiatic continent into the Middle East has climaxed in a tragedy in Iran which is shaking the foundations of the United Nations. Iran, who a few short years ago stood before the UN as a supplicant for protection against the occupation of the province of Azerbaijan by the Soviet, today defies its jurisdiction in the oil dispute with Great Britain.

Time Now For Thinking In these turbulous times a natural restiveness is created among the younger men of the mining profession. Many of them are veterans of World War II and the question is raised in their minds as to whether or not to go back into military service. There is time to think about this question now and it is advisable to do so in order that snap decisions may be avoided if war is declared.

ISOMETRICAL drawing and clinographic projection are generally preferred to perspective drawings for representation of small objects or complicated mechanisms, as they present to the eye a sufficiently accurate picture of the object, while they possess great advantages over perspective in the simplicity and rapidity of execution, and the facility they give for taking measurements directly from the drawings.
