This paper describes the evolution of transportation at an important mining property, beginning at a time when the railhead was 400 mi. distant, and tracing the steps leading to the development of what is probably the heaviest ore train ever operated in underground mine service over narrow-gage tracks, a 300-ton ore train on a 20-in. track, at working costs closely approximating those obtained on systems involving much greater capital expenditure. Useful where geological and financial considerations render inadvisable the excavation and maintenance of large tunnels and heavier rolling stock. THE problem of transportation in the Clifton-Morenci district of Arizona has been one of peculiar difficulty and consequently has been an important factor in the cost of mining and treating the ores produced. From the crude beginning made over 50 years ago, many changes have been necessary to keep pace with the increased output of copper. A heavy-duty haulage system has developed on the original 20-in. track gage to meet the existent metal-mine conditions.

THE year 1923 was one of great importance in northern Louisiana and southern Arkansas, so far as the' development and expansion of previously discovered oil and gas fields were concerned. However, the search for new fields failed to produce a single discovery that led to important development during the period; in this respect, the year was one of discouragement to the prospector. During the winter and spring months, an especially active "wildcat" campaign was in. progress in southern Arkansas, and a large number of tests were drilled in northern. Louisiana but this activity subsided during the summer and fall. By the close of the year, only routine drilling was in effect in the fields; and only two new areas-Cotton Valley, in Webster Parish, and an area in Union Parish, La.-were showing any important activity because of favorable oil showings. Further drilling is contemplated in both of these areas, and the present feeling is that one or the other may produce the next oilfield in this territory. Briefly, the development of the Smackover field was the overshadowing event of the year. In. southern Arkansas, important development also took place in the East El Dorado, Stephens, and Irma fields; but all of these were relatively small. In northern Louisiana, many new oil wells were drilled in the Bellevue field, and many new gas wells in the Monroe field. In the old Caddo field, a large number of the deep Woodbine wells were plugged back to the "chalk rock," where a high gravity oil is obtained. In the other fields, only a few small wells were drilled. Therefore, Arkansas, furnished the real development of the year in this area. The production for the year showed a material increase over that of 1922, due, chiefly, to Smackover, and practically altogether to the Arkansas fields. In Louisiana, every field, except Caddo, Bellevue, and Elm Grove, showed slight to marked declines; while in Arkansas, El Dorado was the only field that declined throughout the year.

THE year 1923 was marked by slight progress in exploring and developing the petroleum resources assumed to exist in Central America. Actual drilling for oil took place only in Costa Rica and Panama. The Sinclair Consolidated Oil Corpn., through its subsidiary the Costa Rica Oil Corpn., drilled in southeastern Costa Rica.. Its, Panaman subsidiary is reported to have abandoned drilling in Bocas del Toro. The Texas Co. drilled in Chiriqui, and the Panama Gulf Co. in Garachiné, Province of Darién. No oil was obtained in any of these wells;' shows of gas were met in Costa Rica. Concession hunting continued during the year. A number of concessions, several of which appear to be purely speculative, were submitted for ratification. Some confusion has been caused by overlapping concessions and claims to oil lands, caused partly by the imperfection of existing maps. A conflict between the Sinclair, and Gulf companies in Panama has been compromised. The Amory concession in central Costa Rica, held by the British Controlled Oilfields, Ltd., was voided by decision of the arbitrator, Chief -Justice Taft. Geologic exploration took-place in Guatemala and in Panama. The chief contribution of the year to Central American geology was a description by Katherine Van Winkle Palmer of Lower Miocene foraminifera and mollusks from southeastern Costa Rica. A new petroleum law was promulgated in Panama.

THE law of supply and demand is, in general terms, that law which governs the price of any commodity in an unrestricted competitive market. There are several variables which, for the purpose of this discussion, will be defined only as they apply to the petroleum industry: Production: The volume of petroleum that is moved from leases. Stocks: The volume of petroleum that is in the hands of the tank farm and pipeline companies. Inventory: The value of the stocks at the market. Consumption: The indicated delivery of oil to others than those who hold stocks. Demand: The potential absorbing power of the consuming market. Demand is the expression of the needs of the consumer and may depend on the economic value of the oil to the consumer. In times of low prices, the demand is the same as the consumption but during periods of high, prices or deficiency in supply, the demand may be greater than consumption. A general expression of the law is, as follows: Production or consumption Some relation between stocks and or controls price or demand inventory

IN a study of the blast-furnace process, the Bureau of Mines has made many experiments for the purpose of determining the exact nature of the combustion of coke in the neighborhood of the tuyeres. Two papers1 presented at a meeting of this Institute discussed somewhat the practical aspects of coke combustibility in its relation to the operation of the blast furnace. In a later paper,2 Sherman and Kinney discussed the possible effect of variations in the combustibility of cokes on the furnace operation, and find that the "reoxidation theory" of Koppers and the "heat concentration theory" of Brassert3 are insufficient to explain the variation in the conduct of different cokes that has been observed by furnace operators. In their report to the D-5 Committee of the American Society for Testing Materials, with which the Bureau of Mines has been cooperating, Perrott and Fieldner4 seem to agree with Sherman and Kinney that, for practical purposes, the nature of the combustion of coke at the tuyeres of any furnace is constant and is affected neither by the physical properties of the coke nor by the nature of the furnace operation. They omit as unimportant any tests on the combustibility of coke from their proposed methods for standard tests on coke. In the last two papers, it is pointed out that performance tests, in which all other factors except coke quality are kept constant, are to be desired and

THE places where, yesterday, oil was unknown contain tomorrow's fields. Unquestionably, some states that now yield little or no oil have great potentialities, and developments in these states, although perhaps of less immediate interest than those in regions where great pools now exist, may easily be of greater ultimate importance than the results of exploration closer to known fields. Not long ago, Montana had only a quarter of an oil pool, and that was regarded by many as an accident that had strayed from Wyoming. More recently, the northern line of Louisiana was a dead line that would not be crossed by any Louisiana operator who valued his reputation for sanity. Within the past few months, Colorado has shown that it is far from being a negligible factor in the oil supply of the Rocky Mountain states, and it is now known that western Kansas, long shunned by many reputable geologists and operators, should be reckoned with. There may be a vast difference between what a wildcat well yields and what the well signifies. The fact that no commercial production is encountered may be lamentable and may well be disastrous to an individual or a company, but the same well that spells ruin to one may convey to another the information that will result in opening a new field. In presenting the conclusions, in this paper, the writer recognizes fully the possibility of erroneous deductions, particularly since he has had contact with only a few of the wells that are mentioned. Information comes principally from the scout. maps and files maintained at the Geological Survey by M. E. Latimer and G. K. Drach, without whose cooperation this summary would not be possible, supplemented by some personal contact and second-hand information gained by. conversation and correspondence. However, it is felt that the data contain few errors, and that the conclusions are at least reasonable.

THE Verde mining district is in Yavapai County, in north-central Arizona. Jerome, the principal town, has a population of 6000 and the two important mines of the district-the United Verde and the United Verde Extension-lie almost within its limits. Perched high on the southwest side of the Verde valley, at elevations of 4800 and 5500 ft. (1463 and 1676 m.) respectively, both mines have long tunnels from their lower levels through which the ore is hauled to the smelters. Clarkdale, the smelter town for the United Verde mines, lies in the Verde valley 4.1 miles (6.5 km.) distant in an air line from Jerome and at an elevation of 3560 ft. The two towns are connected by the standard-gage railroad of the Verde Tunnel and Smelter R. R., a subsidiary of the United Verde Copper Co. This road is 11 miles long and has a compensated grade of 4 per cent. At Clarkdale it connects with the Verde valley branch of the Santa Fe railroad. Clemenceau, the smelter town for the United Verde Extension mine, lies 3.5 miles (5.8 km.) in a southeasterly direction from Clarkdale, at an elevation of 3420 ft. It is connected to the Verde Valley branch of the Santa Fe railroad at Clarkdale by the Arizona Extension R. R., . a subsidiary of the United Verde Extension Mining Co. The portal of the haulage tunnel, at an elevation of 3757.5 ft., is also connected with the smelter town by 4 miles of standard-gage track belonging to? the same company. In the vicinity of Jerome, the great southern escarpment of the Arizona plateau forms the northeast side of the Verde valley. The general level of this escarpment, or "rim" as it is called, is about 4000 ft. above the Verde River. A corresponding elevation is reached only by the highest peaks of the Black Hills, which bound the valley to the southwest. Two lava-capped mesas, known as "Mingus" and "Wood chute mountains," form the culmination of the Black Hills. That part of the Old Black Hills mining district which lies between their crests and the Verde River is now known as the Jerome, or Verde, mining district. If the . smelter towns are not included, a strip about 7 miles long by 3 miles (11 by 5 km.) wide, embraces practically all of the properties belonging to the Jerome district. This strip lies parallel to and along the side of the Verde valley from First View, 2 miles northwest from Jerome, to the vicinity of Allen Springs, at the south end of Mingus mountain and all within the boundaries of the Prescott national forest reserve.

BINGHAM has produced 6 per cent. of this country's copper. In total production, it ranks fourth among the copper camps of North America, the order being Butte, Michigan, Bisbee, and Bingham. In its annual production, it held that same rank until 1919, when its production was exceeded by the combined production of the Globe-Miami district of Arizona. Bingham has also been a lead camp of the first order. Utah ranks third among the lead-producing states, and its production comes largely from three camps which, in the order of their productivity, are: Bingham, Tintic, Park City. Bingham's silver production is important, but it does not rank high as a silver producer. Utah owes its rank as first among the silver-producing states to Tintic, a camp 40 miles due south of Bingham. The United States Mineral Resources reports a total production from Bingham for the period 1865-1920 having a gross value of $528,043,432. Bingham is on the eastern flank of the Oquirrh range 30 miles south-west of Salt Lake City, from which it can be reached in an hour by auto, or by the Denver & Rio Grande or the Bingham & Garfield railroads.. The automobile route is a paved road across the floor of Great Salt Lake Valley, through farming country. The Bingham & Garfield railway leaves the level of Great Salt Lake at the northern end of the Oquirrh range, and in 20 miles it climbs 2100 ft., and deposits the traveler upon a shelf cut in the side of Bingham Canyon below most of the mines, which are farther up Bingham Canyon and its tributary Carr Fork. Below lies the town, a narrow ribbon running for a couple of miles along the bottom of a canyon 2000 ft. deep-an almost impossible site for a community numbering, in prosperous times, 5000 to 7000 inhabitants drawn from all quarters of the globe. Up the canyon and down, and beneath the steep slopes nearby, and beneath the town itself, are the mining operations of over half a century.

A study of specimens shows that the key to both oxidation and enrichment at Duck-town is the behavior of pyrrhotite, which is in part dissolved and in part replaced by marcasite. Enrichment takes place chiefly at the expense of marcasite. THE material that forms the basis of this paper was collected in the spring of 1922, during a ten-day visit to Ducktown by the writer in the company of Prof. L. C. Graton. The time available for the work was far too short to allow anything like a thorough study of the deposits, and structural and stratigraphic questions, though they have an important bearing on the origin of the primary ores, were necessarily left untouched. Attention was focussed on the zone of oxidation and enrichment; and by devoting most of our time to the upper levels, open pits, and old workings, and examining the deeper levels only thoroughly enough to obtain a fair idea of the nature of the primary sulfide ore, we were able to make a reasonably complete survey of the various orebodies. With this field work for a background, the writer later made a study, in the Harvard laboratories, of the specimens obtained during the visit. As some of the facts brought to light by this study appear to be new, it seems worth while to set forth the outstanding features and a proposed explanation of them. Much of the Ducktown material that is obviously of greatest significance, as regards oxidation and enrichment, is soft and crumbly. Notwithstanding the desirability of gaining from such material all possible information as to its mineral composition and textural relationships, but little has heretofore been learned regarding it; but, by suitable preparation of this material in connection with the present study, it has been possible to examine it under the microscope without any disturbance of its texture and about as satisfactorily as if it were hard, fresh ore. The information thus gained has contributed measurably to the results set forth in this paper.

THE prices of crude petroleum and its derivatives have shown an upward trend from 1915 to 1920, and a downward trend from 1920 to 1923, see Table 1. Over the former period, oil prices were dominated by the rapidly increasing demands and inflation incident to the war and its aftermath, while over the latter period oil prices were influenced at the outset by deflation and then by the conditions of overproduction that have characterized the past three years. The purpose of this paper is to analyze the broader features of the more recent price movements in the petroleum industry and to relate these features to basic economic conditions in the industry.

LITTLE new oil was found in West Virginia, during 1923, but there were important discoveries of gas. Most of the large oil producers have contented themselves with pumping old wells or in drilling only enough new wells in defined territory to maintain a fairly constant production, the attitude being that no, profit is made in producing high-grade oil at a low price and that an eventual loss is sustained by draining the reserves of a limited commodity that, at some more favorable time, will be of much value. The representative of one large company said: "We have done nothing but pump old wells during 1923 and we have made no plans for 1924." Careful attention to producing wells has been the rule, there having been few abandonments; the belief is prevalent that small wells will eventually become profitable under more favorable marketing conditions. In natural gas, the opposite point of view prevails. Because of the vast capabilities of the state for producing gas, its output being ahead of all others, great systems of transportation and distribution into the markets of four adjoining states have been built and a demand has been created that no present, or apparently potential, production can satisfy. This demand has become so great that large distributing companies not only discourage new applications for service but advise old customers to install coal furnaces for auxiliary fuel; some have requested public-service commissions to grant higher 'rates against large industrial consumers than those allowed for domestic heating. The response to this known market has been a rapid increase in price, both at the well mouth and at the door of the ultimate consumer, and the industry has become so stable that the only uncertainty, or hazard, appears to be the question of the presence of gas in fair quantity in a given territory under consideration. Several oil companies have now forsaken their policy of selling gas, wells outright when drilled and ;have organized gas departments to drill for gas and to dispose of the daily output by meter to distributing corporations. With such companies and with other producers whose interest is chiefly gas, the year has been busy and profitable. Some new territory of apparently large value has been proved and deeper producing sands in old fields have been tapped.

THE petroleum industry of Indiana made somewhat notable progress during the year 1923, considering the number of handicaps it encountered. The price of labor and materials continued to have an upward slant while the price of crude oil took a decidedly downward course. In spite of these adverse conditions, the quantity production will closely approximate that of 1922, when it passed the million-barrel mark. The progress of the industry in Indiana should be considered fairly satisfactory as long as the present production is maintained. In other words, if the loss of production from the waning old wells can be offset by the production from the new for a period of 10 or 15 years longer, the industry may have cause for congratulation. SUB-TRENTON INVESTIGATIONS In recent years a number of tests of strata lying below the Trenton limestone have been made in Indiana. Several of these tests were completed in 1923. Indications of oil were reported by drillers from several horizons below the Trenton. The most satisfactory of these came from the St. Peter sandstone lying immediately below the Trenton limestone, but no production has yet been obtained from any of the Sub-Trenton horizons. Glen Valley Wells.-Two wells in Marion County were drilled into the St. Peter sandstone, 1 mi. north of Glen Valley and 9 mi. south of Indianapolis. About 30 ft. of sand saturated with a dense asphaltic oil was found in the upper part of the St. Peter sandstone in one of the wells, which contained about 10 per cent. of the light oils, or more easily volatile constituents, and about 90 per cent. of a dark, dense, asphaltic residue. The oil resembled the residue of an asphaltic petroleum from which the more volatile oils had disappeared.

Application of shrinkage stoping methods, without filling, in the mining of large silver-gold orebodies in the Mogollon district, where the ore is hard and wall rocks stand well without timbering and where veins make little water. Vertical and inclined shafts in use with both surface and underground hoisting stations. Storage pockets used on main hoisting levels, with electric signals and telephones for communication. Power is generated by De La Vergne engines having a total sea-level rating of 1540 hp. On account of the remote location of the camp, transportation is an important item of expense, amounting in 1922 to $0.641 per ton of ore milled or $0.265 per ton-mile on all freight hauled. THE Mogollon mining district is in the southwestern part of New Mexico near the southern end of the Mogollon range, from which the district takes its name. The town of Mogollon is but 37 1/2 mi. in an air line northeast of Clifton, Ariz. The air-line distance from Silver City is 52 1/2 mi. and from Tyrone, 57 mi. Supplies are transported by motor truck from Silver City. The distance by road is 75 mi., half of which is an improved highway of modern construction. Transportation has always - been a large item of expense in carrying on operations in the district. Valuable ore is said to have been discovered in the Mogollon Mountains as early as 1870 but the first regular prospecting was carried on in 1875, by James C. Cooney, a sergeant from Fort Bayard. His discovery of rich silver-copper ores in the region of Mineral Creek led to the establishment of the Camp of Cooney. Remote from any settlements where there was a semblance of law and order, and harassed by the Apaches, development was slow and nearly 10 years elapsed before the village of Mogollon was established on Silver Creek. Prospecting in this section of the district had disclosed the outcrops of several promising veins containing silver-gold ores. Among the early claims located were the Last Chance, Top and Confidence, on what has proved to be the most productive vein in the district.

THE development in the Gulf Coastal Plain for the year 1923 was entirely devoid of any spectacular feature and was considerably less than that of 1922. No large fields were discovered and the principal advances lay in the extension of the old fields and the finding of a new dome and other possible producing structures, which, however, so far, have given only small wells. While the production of some fields, such as those at Hull and Orange, was materially increased at times by comparatively large wells, the output as a whole shows a marked decrease over that of the preceding year.

A survey of geological conditions, production and prices in Indiana oil fields. Shows no production and indefinite prospects from the sub-Trenton formation; good production and much untested territory in Trenton formation; and fair production from the Pennsylvanian with fair prospects for the future in both the Pennsylvanian and Mississip-pian formations. THE petroleum industry of Indiana made somewhat notable progress during the year 1923, considering the number of handicaps it encountered. The price of labor and materials continued to have an upward slant while the price of crude oil took a decidedly downward course.

Describes important developments in, four counties, all of which brought in 40° oil. Indications are favorable for the future, although the daily production of the agate decreased 19,000 bbl. during the year 1923. THE state of Kansas had a daily average crude-oil production of about 87,000 bbl. at the beginning of the year. This showed a steady but consistent decline during the 12 months, so that the daily average production at the end of the year was slightly over 68,000 barrels. GREENWOOD COUNTY THE most active development in Kansas during the year was in Green-. wood County, in a line from near Sallyards in T 25-R 9 to east of Madison in T 22-R, 11. The main part of. this development has been in a succession of pools beginning at the south with the Polhamus pool in 34-24-9 and 3 and 4-25-9; Thrall pool in 28, 29, 32 and 33-23-10; Burkett pool in. 13, 23, 24 and 26-23-10; Seeley and Wick pool in 22, 27, 28, 32 and 33-22-11 and 5, 6, 7, and 8-23-11; Frohm pool in 11, 14 and 15-22-11; Madison pool in 31 and 32-21-12 and 6, 22, 12 and 1-22-11. Some of these pools, have two or more sands, locally called Bartlesville and Burgess Sands. They range in. depth from 1850 ft. near Madison to 2450 ft. near Sallyards, the general dip being to the west. The thickness of these sands runs from 20 to 100 ft., the initial production of the wells being 50 to 1000 bbl. of 40-gravity oil or better.

THE advent of the Rocky Mountain States into prominence as an oil-producing region is comparatively recent. Scarcely more than a decade has passed since the number of producing oilfields in this part of the country were few and their combined yield small and relatively unimportant. However, oil was discovered and recorded near the present site of Lander, Wyo., as early as 1833 and in 1867, on the comple-tion of the Union Pacific R. R., the site of this oil discovery was located, among other things, as a natural resource of economic importance. In that year a well was drilled for oil, to a depth of 480 ft., near Evanston, Wyo., but later was abandoned. In 1883, the Lander district witnessed the successful completion of the first oil well in the state. In Colorado, oil was first produced from shallow open wells near Canon City and sold to prospectors in 1864; in 1887, the Florence oilfield was discovered and a commercial production developed. While the Rocky Mountain States have never gained the prominence as an oil-producing region attained by the Pacific Coast, Mid-Continent, or Gulf fields, a substantial and increasing production is being taken from the Rocky Mountain province. At the close of 1923, the oil industry in this region has 38 oil and 21 gas fields producing, or capable of producing, oil or gas in a commercial way with a combined annual yield of nearly 47,000,000 bbl. of oil, a daily refining capacity aggregating about 90,000 bbl., upwards of 17,000,000 bbl. of crude in storage, and an 8-in. pipeline, nearing completion, 600 miles long which will connect the most prolific oilfield of the Rocky Mountain States with a trunk pipeline between Mid-Continent and the east at Carrollton, Mo. Several of the larger standard and independent operating companies are now represented in this region and, in the last ten years, there has been developed at Casper one of the large refining centers of the west. Fig. 1 illustrates the rise in production of four of the larger fields, also in the total production of the state; in addition there is given the yield of the larger fields of Wyoming and Montana for 1923.

IN 1923, Oklahoma took second place as an oil-producing state; whereas in 1922 it was the leader. California surpassed it, in 1923, by nearly 100,000,000 bbl. In 1923, Oklahoma produced, according to statistics of The Oil & Gas Journal, 165,013,685 bbl., or an increase of approximately 10 per cent. over the preceding year; the increase in California was approximately 90 per cent. The number of wells drilled in Oklahoma and the results of the two years are contrasted in the following table from data published in a preliminary bulletin by the U. S. Geological Survey. 1922 1923 Oil wells 4,149,68%. 3,515, 60% Gas wells 571, 9 %u 587, 11% Dry holes 1,428,23% 1,731,29% Total wells 6,148 5,833 The initial production from wells drilled in Oklahoma in 1923, according to The Oil & Gas Journal, was the largest in the history of the state, being 1,277,936 bbl. It has been 32 years since oil development began in the state, last year being the largest in the amount of production. The production of the past year would have been considerably greater were it not for the shutdown order in the Burbank field and curtailment of production in the Hewitt and Tonkawa pools.

ACTIVE drilling operations for oil were carried on during the summer of 1923 in various parts of, western Canada, particularly in Alberta. During the early part of the summer, interest centered in southern Alberta, in the Coutts area, just north of the producing Kevin-Sunburst field of Montana; but on Nov. 14 a strike of oil by British Petroleums Ltd. at its well near Wainwright, 120 mi. east of Edmonton, diverted public attention to a new field. According to present estimates, this well has a possible production of from 60 to 100 bbl. a day; the oil is 15° Be. with an asphaltic base and is obtained from a sand at the depth of 2019-2036 ft. The oil stands at 1700 ft. in the casing and there is sufficient gas pressure to cause it to flow when the well is opened. The oil horizon is in a sandstone in rocks of Colorado age. It is known that there is a terrace structure of which the western edge extends in a northwesterly direction from the vicinity of Hardisty to Viking, where it probably swings more to the north. At Viking a small dome-like structure on this terrace gives rise to an important gas field. Wainwright lies directly northeast of Hardisty. The exact structure in the Wainwright field is unknown. At Fabyan, 6 mi. northwest of Wainwright, the Imperial Oil Co.1 last year brought 1n a large gas well estimated at 14,000,000 cu. ft.; the escaping gas sprayed a small amount of heavy black oil over the derrick. The gas was obtained at a depth of 2727 ft., deeper drilling encountering a water sand. The results of drilling in the Wainwright field are encouraging for future development.
