IT is certainly fitting and proper that the shortage of engineers should be the topic of frequent editorials in the professional magazine of mining engineers, but many of you are directly concerned with another shortage; namely, the shortage of skilled miners. It is often said that the military organization is built around the noncommissioned officer and it is similarly true that the mining organization depends for its production on the skilled miner-the NCO of the mining industry.

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 four different modes, more or less practiced for subdividing slag (that is, producing slag sand), are the following: 1. Crushing the slag from the lump in Blake's crusher, by edge runners or other suitable means. 2. Blowing water, steam, cold or hot air, into the stream of viscous slag whilst it runs from the furnace. So treated, the slag takes

AN X-ray diffraction pattern for "calcined cold precipitated ferric oxide" is reproduced diagrammatically along with data for other iron oxides by R. C. Mackenzie.1 This pattern, which shows spacings higher than those for any other form of iron oxide, was obtained from material prepared and photographed at several different times over a period of weeks, but later attempts to reproduce the results were unsuccessful the pattern of hematite being obtained every time.2

TO recover the remaining ore tonnages along the south side of the Inspiration orebody, the company began open-pit operations in early 1948 in addition to underground mining. Due to the differences in elevation between the orebody and the existing ore handling and treating plants, the truck haulage operation is up hill. Road grades were established at 7 pct maximum.

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..

(Read at the Amenia Meeting, October, 1877.) DURING the summer of 1870, I had an opportunity to visit the laboratory of the late David Forbes, Esq., in London, and was much interested in a labor-saving device which lie had attached to his agate mortar. The mortar was placed in the centre of a small table, and about ten inches to the right of the mortar, a post, perhaps two

The total production of crude oil in Canada showed only a small improvement in 1936 over 1935, but developments of great importance took place in Alberta on the west flank of the Turner Valley field in the foothills southwest of Calgary. These have led to renewed activity in drilling such as has not been experienced for many years, and undoubtedly this will result in a very considerable increase in the oil production during 1937.

(communication to the Secretary*):—The authors say, "The factor which determines the completeness of combustion of tlie volatile matter, after it has bee11 mixed with a certain amount of air, is the length of time the mixture is allowed to remain in the combustion-space; but this length of time depends on the extent of the space itself."
