The problem of increasing blast-furnace efficiency through diminution of flue-dust production while operating with burdens consisting largely of fine ores has of recent years attracted the attention of metallurgists, whether directly or indirectly interested in the economies of iron smelting, and the various methods evolved from theory or practice have been submitted to wide discussion. After the very thorough and, at that time, exhaustive view of the whole subject, which was afforded to the industry by the meeting of this Institute in February, 1912, the subject was again taken up at the meeting of the Verein deutscher Eisenh?ttenleute at D?sseldorf in December, 1912. While American and German conditions are not entirely identical, it may be of interest to give here the words of the gentleman summing up the discussion at the Diisseldorf meeting: " The chief advantage offered by the use of briquettes lies in the fact that disturbances in the furnace, caused mostly by the presence of fine ores in the burden, are avoided, and that blast pressure can be considerably reduced. The resulting economies cannot be overrated, as, with lower blast consumption per ton of product, the installation will be able to take care of increased production. In consequence of lower pressure and speed of blast, heat is more efficiently utilized, flue gas temperature is lowered, and coke particles are less liable to be carried along with the flue dust, of which considerably less is produced. Finally, by increased regularity of operation and higher temperature in the lower parts of the furnace, the quality of the product is improved. The question of briquetting iron ores has grown to be one of the most important in the iron industry, and it is not any more a question of what is the cost of briquetting a ton of ore, but what, in using ore briquettes, is the cost of production of a ton of iron." Dr. A. Weiskopf, of Hannover, admirably condenses in these words

AN unprecedented expansion of the mineral industries began in mid-1950. There are few minerals on the strategic list for which some source of supply here at home has not been found. All types of inducements have been utilized, ranging from RFC loans to guaranteed-price purchase contracts. No one can deny that tremendous progress toward mineral self-sufficiency has been made. Despite the greatness of these accomplishments, made' in the name of national defense, one cannot help but. have a feeling of uneasiness over the price which has been paid-in indebtedness, in freedom, and in the sacrifice of private enterprise. The people of the Soviet have been enslaved by a military state which attempts complete control of the economy. A similar yoke has been imposed on the business life of this nation. Of course, there is a difference in degree of control and in purpose. We are dedicated toward defense and the resistance of aggression. And, our personal liberties have not been usurped. The realization of the extent to which this nation has been forced by Communist aggression to adopt the practices of the socialized state is appalling.

Pneumatic stowing is commonly employed in European coal mines, but is not used in the United States. This paper reports a study conducted to analyze the conditions under which pneumatic stowing might be advantageously used and the techniques and costs involved in order to effect this. Although stowing may reduce the subsidence in a mining area, this does not entirely eliminate the surface damage. Besides, the cost of stowing will run about $1.50 to $3 per ton of coal mined not including the cost of fill material, if it has to be bought and transported to the mine. Stowing my, however, be economically viable under special circumstances such as in thick, steep, or contiguous seams.

Theodore Dehon Rand was appointed Treasurer of the American Institute of Mining Engineers by the Council, at the Boston meeting of February, 1873, to fill a vacancy caused by the resignation of the treasurer who had been elected at the first meeting in Wilkes-Barre in May, 1871. He was elected by the Institute to this offce in the following May, and yearly thereafter until 1903. He often alluded with amusement to the abrupt way in which he was injected into this position, by my coming to his office and asking him to accept the appointment as Treasurer, on the ground that he was eminently fitted for the position by reason of his legal and business knowledge, his interest in geology and mineralogy, and more particularly because he was a neighbor of the person (to wit, myself) who was slated for the Secretaryship, and they could thus convenient.ly confer on Institute matters. He consented, on condition that the duties should not involve too.much additional work for him. This assurance was easily given, for the Institute then

The following notes, prepared in 1908, as the result of a personal examination and extensive explorations under my direction in 1906, have been revised and greatly augmented after two subsequent visits and further explorations in 1910. The hard iron-ores of the south coast of Oriente Province, in the island of Cuba, have been known for many years, in fact one mine has been in operation for more than 20 years; but it is only within the past four years that the large mantle-deposits of brown ores of the north coast have attracted serious attention. A. C, Spencer' has described these ores in a paper, entitled Three Deposits of Iron Ore in Cuba, which refers to the Mayari, Moa, and Cubitas deposits. C. M. Weld,2 in a scholarly paper, The Residual Brown Iron-Ores of Cuba, has discussed the character and possible genesis of these deposits with particular reference to the Moa field, calling attention also to the Taco and Navas fields in addition to those described by Spencer. Descriptive articles with reference to the Mayari field, and a few words about the Moa deposit, have also appeared3 It is the purpose of the present paper to give some account of the exploration of the Moa deposit arid to call attention to its commercial importance. Location. The Moa district is situated on the north coast of the Province of Oriente, which is the most easterly province of the

It is my desire to call attention to a new industry which was started about four years ago, through the discovery by Mr. John Holland, a resident of this city, of the methods employed in working the metal iridium. This metal has been known since the year 1803, having been discovered by Smithson Tennant while investigating the metallic residue which remained when platinum ores were dissolved in aqua regia. The metal is classed among the rare metals, as it is not found in large quantities, although it is quite widely distributed geographically. It is found in California, Oregon, Russia, East India, Borneo, South America, Canada, Australia, and in certain parts of France, Germany, and Spain. The principal sources of supply of the metal are Russia and California; it is nearly always found with either platinum or gold, is extracted from those ores as a by-product, and is always found in small grains or fine powder, the largest pieces being about the size of a grain of rice. In nature it is generally alloyed with other metals, and the two metals with which it is most commonly alloyed are platinum and osmium; the platinum alloy is called platin-iridium, and the osmium alloy osmiridium, or iridosmine. The grains of platin-iridium are

Forty years ago the atom was split and the Age of Fission dawned. Uranium was the element used in this earth-shaking accomplishment. Thitherto almost unknown to the man in the street, uranium soon became widely and persistently sought. And the quest for this unique material is not likely to diminish during this century. To find is one thing; to own is another. Who owns uranium in the ground? Where no mineral rights in the land have been severed by devise, grant, reservation or lease, the uranium belongs to the fee simple owner of the land. But where there has been a conveyance or reservation of all or part of the "minerals", determining WHAT a substance is has been the traditional way of determining WHO owns it. What, then, is this element called uranium? The 1907 edition of Watts Dictionary of Chemistry calls it "a lustrous, hard, silver-white metal". Of nature's three prime divisions it falls within the embrace of the mineral kingdom - substances neither animal nor vegetable. In its natural state uranium always is combined with other elements or substances in the form of an ore mineral. May we, then, put to rest any doubt or question as to the nature of uranium and classify it for all purposes, including that of ownership, as mineral? Not quite! That self-same logic would find oil and gas primly ensconced in the animal or vegetable kingdom. Technically, oil and gas are not minerals but legally they have been classified as such. Why? The Supreme Court of Tennessee sought the answer in 1897 in the case of Murray v. Allard, 43 S.W. 355. After citing authorities pro and con, and while admitting their origin to be "decomposition of marine or vegetable organises" that court firmly concluded that since they were obtained by a form of mining, oil and gas were minerals. From the above example two elementary truths emerge. First, for purposes of ownership, uranium is and will be whatever the courts say it is. Secondly, the courts historically and currently favor a practical rather than technical test to determine the "mineral" character of a substance. So now we turn to the jurisprudence for enlightenment and definition. EARLY CASES ALLOT URANIUM TO MINERAL OWNERS Two early cases involving the ownership of uranium followed what had been well-settled mineral within the meaning of the conveyances involved, confirming ownership in the mineral owners. In 1956 the U. S. District Court for New Mexico in the case of New Mexico and Arizona Land Company v. Elkins, 137 F. Supp. 767, appeal dism'd 239 F.2d 645 (10th Cir. 1956), found that a 1946 deed reservation of "all oil, gas and minerals underlying or appurtenant to said lands" included uranium and thorium. The court reasoned that uranium and thorium, being minerals within the scientific, geological and practical meaning of the term, would certainly constitute minerals within the purview of the reservation. While agreeing that uranium and thorium were "minerals", defendants argued that at the tine of execution of the conveyance it could not have been the intention of the parties to reserve them because they had no commercial value in the locality and were, in fact, not known to there exist until their later discovery in 1950. The court re¬jected, as a matter of law, this "lack of knowledge" theory citing the Supreme Court of Kentucky holding in Maynard v. McHenry, 113 S.W. 2d 13, that: "The mere fact that a particular mineral has not been discovered in the vicinity of the land conveyed or is unknown at the time the deed is executed rules of construction and held that uranium was a does not alter the rule . . ." that a grant or exception of "mineral" in a deed includes all mineral substances which can be taken from the land unless restrictive language is used indicating that the parties contemplated something less general than all substances legally cognizable as minerals. Further, argued the defendants, the only feasible mining procedure for such substances was open pit or strip mining, which would destroy the value of the land for grazing or agriculture. Finding that the language of the reservation was clear and unambiguous, the court would not permit the admission of extrinsic evidence as to mining procedures required. Elkins is the first uranium case construing the granting clause involved. In 1958 the Texas Court of Civil Appeals at San Antonio, in Cain v. Neuman, 316 S.W. 2d 915, no writ, held that a 1918 lease conveying "all of the oil, gas, coal and other minerals in and under" the land involved covered uranium. The lease provided a royalty of 1/10th on "other minerals." "We find no Texas precedent which discusses uranium," said the court, "but the usual arguments that uranium is not embraced within a lease are that the ejusden generis rule excludes uranium from the meaning of the lease

The volumetric behavior of five mixtures of black oil and natural gas and of two mixtures of condensate and natural gas from a field in the San Joaquin Valley was experimentally established. This work was carried out at roo°, I9o° and 250°F in the pressure interval between 400 and 5000 psi. The viscosity of the liquid phase of four mixtures of black oil and natural gas was experimentally measured in the above-indicated temperature and pressure intervals. The effect of methane upon the precipitation of bitumen from the black oil was studied at 230°F. Introduction The solution of a number of the economical and technological problems which arise in connection with petroleum production is dependent upon the availability of the necessary quantitative information covering the materials involved. This requires data concerning physical properties of naturally occurring hydrocarbon mixtures at the pressures and temperatures characteristic of underground petroleum reservoirs. The experimental determination of the desired data for each situation encountered is relatively time-consuming. However, it is considered to yield results sufficiently more reliable than those obtained from correlations to justify the effort. For these reasons there was undertaken a laboratory investigation of the viscosity of the liquid phase and the volu- metric and phase behavior of mixtures of oil and gas samples obtained from wells in a field located in the San Joaquin Valley. Terminology The nomenclature of petroleum engineering is not at present entirely standardized. Many commonly used technical terms are not everywhere given the same meanings. For the purposes of this paper the following definitions will be adopted: Black oil refers to the dark-colored, hydrocarbon liquid obtained when the producing horizon of the well lies partly in the condensed hydrocarbon phase of the reservoir. Condensate is the term applied to the relatively volatile, pale yellow or amber-colored hydrocarbon liquid that is often obtained from the surface separator system when the producing horizon of the well lies in the gas cap of the reservoir. The gas obtained from the surface separator system is called natural gas regardless of whether the well is producing black oil or condensate. As might be expected from the multi-component character of naturally occurring hydrocarbon materials, the compositions of black oil, condensate and natural gas are subject to considerable variation depending upon the temperatures and pressures prevailing in the surface separator system as well as upon the overall composition of the material produced from the reservoir. In order to obtain samples capable of reproducing the total hydrocarbon material produced by the well, all oil and gas mixtures used in this investigation were com-

The decline in deliverability of conventional natural gas supplies and the general energy crisis have resulted in national programs directed toward the commercialization of energy conversion technologies. Foremost among these efforts is the gasification of coal. Coal reserves represent our most abundant fossil fuel resource. Its utilization is hampered both by its form value and its pollution qualities. Coal gasification is commercially feasible today and projects requiring hundreds of millions of dollars and years of construction time are underway. This paper provides a perspective for the scope, time, and cost of these venture projects. Resource requirements, plant products, and coal gasification processes are discussed. Emphasis is placed on the effects of coal feedstock and prices on plant economics.
