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.

W. M. Courtis, Detroit, Mich. (communication to the Secretary) : Having made a rapid examination of the deposits described in this paper, I am not inclined to generalize confidently concerning its geological relations. But, since an analysis furnished by me has been included in the paper, it may be of further use to give the results of other samples and analyses. I give, therefore, a table of analyses by different parties, showing the average from surface-specimens:

The question as to what grades of ore it pays to conserve for the future, and the valuation of low-grade reserves, are becoming immediate and definite as applied to the individual ore deposits, and seems to call for some sort of quantitative answer.

Take a look at the maintenance force in some of Wyoming's surface coal mines and you'll notice a significant change-the workers are younger than ever and many have had little or no prior experience. The change is quite a departure from industry's previous "experienced only" hiring policy. It results, in part, from a successful training program offered by Casper College in Casper. Wyo..

COPPER sometimes is added to steel and cast iron as an alloying element to improve or impart specific properties. However, in some steels it exerts an impurity effect in impairing response to fabrication by hot working and deep drawing. The resid-

THE occurrence of superplasticity in Al-Zn alloys is of interest because of its possible industrial exploitation.' The eutectoid composition (78Zn-22A1) has been the most extensively studied;'-= neck resistant flow and high strain rate sensitivity of flow stress (characteristic of superplasticity) are associated with a micron-size grain conferred on the alloy by an homo-genization and quench.5'6 Compositions away from the eutectoid have received comparatively little attention, especially from the viewpoint of relating the structural

Diphenyl guanidine is used as an accelerator in vulcanizing rubber. Other rubber accelerators are also flotation collectors, e.g., dithiocarbamate, thiazole, and the xanthates. Urea and its derivatives are good flotation collectors,1 and guanidine is the nitrogen analog of urea. These two characteristics suggested testing diphenyl guanidine as a flotation collector. Diphenyl guanidine has been tried in flotation work previously, but references give no details.2-4

The airplane, while not a product of the war, owes its present very prominent place to the war; if it had not been for the war its development would have been retarded many years. War planes were made for various purposes, but their most important use was for photographing the enemies' lines. The same methods; with some modifications, are now
