New York was bathed in pale winter sunshine and, surprisingly, coatless weather. The time was the AIME Centennial and 100th Annual Meeting. From advance peeks into the fabulous schedule of events we were well aware that the Centennial Committee, New York Host Section and AIME staff' had pulled out all the stops, laying on the best of everything, but the weather gimmick was the frosting on the cake. The Formal Greetings Session on the first morning, Joe Alford confided, was the greatest AIME experience of his life. Without doubt the honor bestowed on AIME by the greetings and felicitations of the presidents of the world's leading professional engineering societies was the greatest moment in AIME history-save one. That one exception was in 1928, when 1920 AIME President Herbert C. Hoover was elected President of the United States.

Lithium raw materials usable with present technology consist of pegmatite ore and shallow evaporite brine. Deposits of these materials occur in many parts of the world. Those advantageously located supply the present lithium industry. Less favorably located deposits will come into production as markets expand and present sources are depleted. In this discussion, materials listed as reserves include fully explored and partly explored deposits. For those closely drilled and assayed, the data provide measurements rather than estimates, and such reserve tonnages are "proved." For deposits partly explored, the data support reserve estimates of "probable" tonnages. Materials lacking exploratory data are classed as resources, and their "possible" tonnages are inferred mostly from indirect evidence and are essentially objectives for exploration. All figures for pegmatite ore apply to total materials in the ground.

GWILLIAM H. CLAMER* (Philadelphia, Pa.).-Sulphur is not so detrimental in its effect if oxygen is also present, so that in sulphur-carrying bronzes and brasses, it is advantageous to maintain a certain percentage of oxygen. As a matter of fact, it would be possible sometimes to correct difficulties by actually adding oxygen. If the cathodes were charged directly into an electric furnace in a neutral or reducing atmosphere, a very high grade of copper would result by a simple melting operation. This would very largely eliminate the loss occasioned by melting in a reverberatory furnace. In such a furnace a large amount of slag is produced during the oxidizing stage of refining. Notwithstanding the fact that melting in an electric furnace might be somewhat more expensive than melting in a fuel furnace, the ultimate result would be a saving and the production of a very high grade of copper.

Drilling activity in Nebraska continued to decline during 1944. Nine tests for oil and gas were completed during the year and four wells were drilling at the close of the year. Four wells were drilled in Richardson County, three in Hitchcock County and single wells were drilled or drilling in Butler, Gage, Holt, Nemaha and Scottsbluff Counties. Only one of the completions resulted in commercial pro- duction, the others being abandoned as dry holes. A number of stratigraphic test holes were drilled in the state by the Stanolind Oil and Gas Co. and the Sinclair-Prairie Oil Co., in Johnson, Otoe, Chase, Dundy and Garden Counties. No new fields were discovered during 1944 but the limits of the Barada field, Richardson County, was extended a short distance southward. Oil production continued to drop and about two thirds as much oil was produced in 1944 as in 1943.

The Reconstruction and Research Division of the United States Council of National Defense has, up to date, prepared two reviews on the above subjects: one covers foreign countries and the other covers the activities in the States. These reviews contain information appearing in various Governmental and public periodicals. While the information on foreign countries is necessarily incomplete and fragmentary, its summation is perhaps the most complete work of this kind so far accomplished. The information from the states consists mainly of bills and ordinances introduced in the state legislature, municipal councils, legislature committee reports, programs suggested by governors, and other state and local officials and local organizations It is realized that a good deal of this information will be useful to engineers studying conditions in the various states, and especially to those who want an insight into the general condition in all the states. For instance, the reconstruction problem in each state involving highway, reclamation, buildings, etc., are covered in detail.

F. McMillan Stanton was born in New York City on May 23, 1865, the son of an English father and of a mother whose family was linked with that of Peter Stuyvesant. Mr. Stanton took his degree from the School of Mines of Columbia University in 1887, worked for two years as an assayer and surveyor and then went into the mining field on his own account. After a few years, he was offered a position with the Atlantic Mining Co., and began the work which was to continue with marked success for twenty-three years. In 1910, Mr. Stanton retired and went to Europe for a rest. Upon his return in 1914, he was elected treasurer and director of the Mohawk Mining Co., the Wolverine Copper Mining Co. and the Michigan Copper Mining Co., to which group was later added the White Pine Extension, Copper Co., and continued to serve these companies until the time of his death, Sept. 12, 1916.

IN mining in Malaya has been a courageous ad- venture in private enterprise, attended by all the hazards of prospecting in unexplored areas of tropical jungles-jungles that still cover four-fifths of the country. To assess the contribution of an industry to a country's revenue, it is necessary to consider not only duties levied on the products, but also the revenue from all businesses and individuals directly and indirectly deriving income from the industry. Exact figures are not obtainable, but from 1850 until shortly before the first World War, tin mining in Malaya was a dominant factor in the Federation's development. Even at the turn of the century, tin export duty alone represented 45 pct of total Government revenue, while in the 40-year period up to the end of 1937, tin ore duties collected by the Federated Malay States Government amounted to 383,- 81 0,284 Malayan dollars,* approximately one-fifth of the total revenue for the same period.

The tight electric power supply is one of the most dramatic problems facing the mining industry in 1971. This is caused by rising demands for energy. Clean-fuel and air-pollution controls have contributed to the problems of producing energy from sulfur oil and coal. Coking coal has become scarce. One stimulating development is that coal is no longer the cinder in the mining industry's eye. In fact, it may be the favorite candidate as a base for fuel within a few years. Synthetic gas from coal is the watchword. In dedicating a multi-million- dollar project aimed at converting coal into oil and gas, Hollis M. Dole, Assistant Secretary of the Interior, recently made it clear that coal, which has been taking a back seat to nuclear fission research and study grants, is now coming into its own. Conversion pilot plants are being activated in all parts of the nation.

Presence of hot water brought on by volcanic action nearby has severely complicated mining in the Limon gold mine in Nicaragua. Routine pumping problems have been multiplied and ventilation is a major problem. Enclosing rock is so hot that 20 pct of all power generated at the mine is consumed by forced ventilation. But hot water underground, however disagreeable and troublesome, may be handled and surmounted like any other difficulty if the estimated profit margin permits. Empresa Minera de Nicaragua's Limon mine is a 400-ton gold-silver producer located in western Nicaragua about 60 miles northwest of the capital city, Managua, and some 45 miles from the Nicaragua-Honduras border. Limon is situated in a low- lying district with a nearby chain of active and semi-active Tertiary volcanoes.

The following very cordial letter, addressed to the President of the American Institute of Mining Engineers by the President of the graduates of the School of Mines of Saint-Etienne, will he deeply appreciated by all American engineers and will perhaps be of use to engineers going "Over There." Members are requested to communicate the substance of this letter to friends or acquaintances in France: Dear Mr. President: Now that the American armies are crossing the ocean to come to our side in the defence of the liberty of the world, and the intellectual elite of your great country is very ably cooperating with us in this supreme struggle, we ardently desire to give them a whole-hearted reception upon their arrival on the shores of France. The representatives of your illustrious association will be more especially welcome among their French colleagues, and both at Saint-Etienne and at Pans, we desire that their sojourn he rendered comfortable and congenial in every way possible. We therefore put ourselves unreservedly at their disposal. At Paris especially those of our colleagues

For the producer of industrial rocks and minerals, marketing is often the only means of survival. His material must be sold. There is little of the impersonal force of the market regulating supply and demand. No commodity exchanges facilitate his efforts to dispose of the material he produces, and the success or failure of his business depends primarily on prompt and correct response to market needs and requirements. This response is particularly vital where materials of low unit value must be shipped to distant consumers owing to a relative rarity of suitable deposits. The advantage of positive response to change can best be illustrated by hypothetical cases showing how problems can be turned into opportunity through marketing ingenuity. Three such cases dealing with materials of unit values in the range of $5 to $100 per ton are outlined below.
