SINCE we used Chief Buehler's name last year to give our annual report a semblance of respectability, we can follow the good precedent thus established by telling of the work his Missouri State organization has been carrying on, as reported by H. S. McQueen. Considerable value is set upon their magrletorneter working which has covered over 13,000 sq. mi.), for the indications it gives of the major structural features of the region. Numerous geological problems have been tackled Ly resistivity techniques, among which are the locating and outlining of filled sink deposits of sulphides, of iron ore, and of fire clay; tracing of faults and solution channels; mapping of the preglacial structural pattern; measurement of depth of overburden; and

The ores of zinc which are important as sources of that metal are of two classes, viz., the sulphide and the oxidized. The latter includes six varieties: zincite (the red oxide) and franklinite (the oxide of zinc, iron, and manganese), which are found abundantly only in New Jersey; and the hydrous and anhydrous carbonates, the hydrous and anhydrous silicates, which are of widespread occurrence. The hydrous carbonate is known mineralogically as hydrozincite, zinconise, or zinc-bloom; the anhydrous silicate is recognized as willemite. With respect to the anhydrous carbonate and the hydrous silicate, however, there is a confusion of name which is of old standing. Attempts to clear it away were long ago made by the mineralogists with the result that there is now a more or less national uniformity of nomenclature; but there is still an international disagreement, sometimes very perplexing and always leading to inexactness in expression, which may be considered an adequate excuse for this return to a time-worn subject. The name calamine, together with Galmei of the Germans, is commonly supposed to be derived from xadµela, which was used by the Greeks to designate the peculiar kind of ore employed with copper in their brass-making, and also the accretions which formed in the brass-founder's furnaces. Agricola, however, says that it is from calamm, a reed, in allusion to the appearance of the material, cadmia fornacum, which collected 011 the furnace-walls. But whatever the derivation of the word, it was used until within one hundred years to include all the oxidized

ANDREW FLETCHER, newly elected Treasurer and Director, has spent his entire mining career in the employ of the St. Joseph Lead Co. and brings to the Institute Board a career rich in financial experience and varied in interest and accomplishment. "Drew" Fletcher was born in New York City on Feb. 6, 1895. After graduating from the Sheffield Scientific School of Yale in 1916 as a mechanical engineer, he became a shipyard mechanic in Wilmington, Del. The next thirteen years saw. him gradually enlarging his responsibilities until he ultimately became the head of the W. & A. Fletcher Co., in Hoboken, N. J., ship repairers. In 1929 his program for merging the Fletcher plant with five other New York shipyards was finally consummated in the formation of the United Dry Docks, Inc., which subsequently was purchased by Bethlehem Steel, with the result that today the old Fletcher yard and organization has been expanded into one of the finest ship repair units in the United States.

WINFIELD SCOTT MORRIS, known from Coast to Coast within the petroleum industry as "Buck" Morris, is and has been for several years an outstanding man in the Petroleum Division of the A.IM.E., so it is most natural to have him as the Chairman of the Division. "Buck" has been such a vociferous promoter of everything TEXAS that most of his friends believe him to be a "Longhorn" by birth-but the records show he was born at Wilmington, N. C., on July 29, 1901. He worked his way through college and graduated from the University of North Carolina in 1924 with a B.S., followed by a C.E. in 1927. His graduation thesis was entitled "De¬sign of a Modern Oil Refinery."

WITH the supply of zinc, like that of most other nonferrous metals, inadequate to meet the demand, efforts to increase domestic ore supplies and production capacity have been of primary interest. No major sources of new ore have been disclosed during the year but improvements have been reported in facilities for mining and concentrating ores from existing mines. The American Zinc, Lead and Smelting Co. has announced its intention of erecting a new mill in the Ouray district of Colorado. The Consolidated Mining and Smelting Co. of Canada is reported to be planning improvements costing $3,000,000 to its Sullivan mine and concentrator at Kimberley, B.C., where the sink-float process is to be used for preliminary ore treatment. In the reduction field, the St. Joseph

PROBABLY no man has been of greater service to the Institute and has kept more in the background than Henry Krumb. A Vice-President continuously) for the last eleven years, apparently neither his picture nor a biographical sketch ever have adorned these pages and were he forewarned in the present instance he would order us to "forget it." He is a Columbia School of Mines man, Class of '98. He worked underground at Rossland, B. C. for a time, then for a year and a half a. chief engineer of the famous Camp Bird at Ouray, Colo. For three wars he was examining engineer for the Guggenheims and since 1901 has been an independent consulting engineer with experience throughout the Americas.

Discussion of the paper by CHARLES A. MITKE, presented at the San Francisco meeting, September, 1915, and printed in Bulletin No. 105, September, 1915, pp. 1941 to 1958. GERALD SHERMAN, Bisbee, Ariz.-Mr. Mitke justly might have made much stronger his claim for increase in efficiency of labor due to the introduction of forced ventilation. The product per man shift in stoping in the Gardner division has practically doubled. While it is true that improved methods have been responsible for a great part of this gain, and what is due to better ventilation cannot be definitely known, yet it is also true that the results could not have been obtained in that division as it was in 1912. . The paper discusses the two systems of ventilation in use, exhaust and pressure. In both the object is the same, to take foul air or gas out of the mine by the most direct course and replace it by fresh. In coal mines, the exhaust system is in almost universal use, and since the most advanced work in ventilation has been in that class of mines, it was naturally the first one to be considered. It has the advantage of leaving all adits, shafts, or other openings free for use. Doors are only needed to direct the course of the air, and not to confine it. Its disadvantages appear in case of fire, or if the ground over the mine is much broken by subsidence. The fan must work in gas in the case of a -fire, and may be. damaged or destroyed either by heat or by corrosive gas. At the time of the fire in the Lowell division of the Copper Queen, a small exhaust fan was placed over a ventilating raise, but the vanes and housing were destroyed by sulphurous gases within a few weeks. If the ground above the mined area is much broken, as is frequently the case when the ore deposit is thick vertically, a good deal of air is likely to pass through it, particularly if it is near the surface. Leakage from this source is a loss to the exhaust system by short circuiting, which is exaggerated by a contraction or block in the air course. It serves as an added outlet in the pressure system. This is strikingly shown at the United Verde, where many jets of steam may be seen coming up through the ground above the stoped country on a cold day.

THERE have always been in this world men of such keen intelligence that with their discourse they have been capable of infinite and various inventions that are as beneficial as they are simultaneously harmful to the human body. Wherefore, from day to day, we see unfolded before our eyes some of these that greatly astound our minds, and we remain so stupefied that when-we think of them we are not able to control our faculties for some time, both from considering by what necessity or purpose these men were goaded, as well as from contemplating the profound subtlety of their discoveries, which, in truth, are such that they are awarded the greatest commendation by noble minds. By following their counsels and with their aid, there have been* some astute and lever captains who have had certain pots or balls of earthenware carried by their infantry, expressly filled with compositions of powder or other unctuous liquors disposed to ignite easily. When they meet the enemy in battle and come up close to them, they try to strike vigorously with these in the first assault in an effort to throw them into disorder and to make them give way by breaking them up and drawing them out of formation. The smoke is harmful, but the fire very much more so. These are made in this way. Take the number of vessels that you have to make-it does not matter whether they are raw or baked as long as they are well freed from the moisture of the clay-and fill them a little more than half full with coarse gunpowder which has mixed in it pounded Grecian pitch and at least a third of crushed sulphur. Then pour in a covering a dito thick of strained pig fat mixed with powder. This keeps it from falling out when it is thrown and keeps the fire slower until it reaches the enemy. When this has been made, open up the pig fat a little at one side when you wish to throw it and put in a little fuse or a little good powder and apply fire, holding it in your hand until you see that the fire has taken hold well. Then throw it, choosing your time. A liquid composition is also made in a kettle in which are put pork fat, petroleum oil, oil of sulphur, live sulphur, [163] doubly refined saltpeter,

JOHN HUNTER NEAD, chief metallurgist of the Inland Steel Co., Chairman of the Iron and Steel Division for 1939, a native of Missouri and graduate of the University of Michigan, first taught chemistry after graduating from college and then decided to follow the field of his college specialization and be a metallurgist. In succession he was associated with the H. H. Franklin Co., Syracuse, N. Y., the Watertown Arsenal, the Racine Steel Castings Co., and the Minneapolis Steel and Machinery Co. During the World War he held a commission as Captain in the Ordnance Department and served both overseas and on the technical staff in Washington. Returning to civilian life, Hunter Nead was research metallurgist and then chief metallurgist of the American Rolling Mill Co. from 1919 until 1931, when he went to his present position with Inland.

NOT a few physical metallurgists started their profession- al careers as chemists or physicists, only to surrender later to the attractions of metallurgy. The present Institute of Metals Chairman varied this more usual sequence in hat his first love was electrical engineering, when as a recent graduate he served on the staff of the General Electric Co., of Schenectady. Soon turning to metallurgy as a more interesting field, he was metallurgist and then chief engineer of the Wads- worth Watch Case Co. from 1920 to 1927. Since 1927 he has been with the International Nickel Co. at the Bayonne, N. J., research laboratories where he is staff adviser.

THIS issue is about Chuquicamata and the new sulphide plant. Chuquicamata is moving into a new cycle of productivity; she has begun to give up the sulphide copper which lies deep-seated beneath the oxide ore zones in large but yet unknown quantity. After forty years of production, Chuqui may be likened to a strapping youngster, with adolescence and maturity still ahead. Mining operations are being projected-not for decades -but for generations. Although there are still many years of open-pit mining ahead, planning of future underground mining has been started. The bottom of the orebody is still unknown, but enough work has been done to show that Chuqui is one of the largest known copper orebodies in the world. Until recently, only the oxide ores have been mined and these have been treated at the rate of 50,000 to 60,000 tons per day by leaching. Construction of the sulphide plant was timed to coincide with reduction in production of oxide ores. The new sulphide concentrator and smelter, designed in keeping with the magnitude of the orebody, will be brought on the production line at the rate of 30,000 tons per day. The capacity of the plant now planned can be expanded to treat 60,000 tons of sulphide ore. Little wonder that Chuqui is a name legendary in the remotest mining circles. But to those who have known her more intimately, and there is hardly a mining camp without a Chuqui graduate, she means much more. She is an orebody that has made engineers. Reposing at 10,000 ft on the western flank of the Andes in the arid northern reaches of Chile, water is scarce, common fuels absent, and volcanoes and earthquakes add drama and hazard. It is these natural difficulties which have created the fascination and challenge which have caused many engineers to devote their lives to unlocking this treasure house of nature.
