Outstanding advances among the metals, marked the mineral production records for Canada during the first half of 1925. Production of metals and non-metals reached a total value of $90,347,698. as compared with $84,307,385. in the first half of 1924, an increase of 7.16 per cent. Metals and non-metals produced during the calendar year 1924 were valued at $17 4,202,537.; production during the first half of 1925 showed a sum equal to 51.86 per cent of this total. Advances among the metals were general. Gold rose to a new record. Lead advanced 62.41 per cent over the high mark attained in the first half of 1924. Nickel production was well maintained. Copper was up a million pounds. Silver showed increased values. Zinc followed the trend in lead to almost double the output recorded in the first half of 1924. Cobalt production continued to improve. Despite the loss due to the protracted strike in the Nova Scotia coal mines which reduced the output of coal in that province; during the six months ending June, to less than half the tonnage reported in the first six months of 1924, improved conditions throughout the rest of the non-metal mining field resulted in the production of non-metals during the half-year reaching a total value of $31,199,233. as compared with $36,844,286. in the first half of 1924; the loss in the value of coal output al one amounted to $5,723,873, while the decrease in the aggregate value of non-metals amounted to only $5,645,053.

Since April, 1923, the Scientific & Industrial Research Council of Alberta has had an analyst, Mr. W. P. Campbell, steadily employed analyzing coal samples taken by the provincial Mine Inspectors. Mr. Campbell has also analyzed a number of coal samples taken by one of the Council's Geological Survey parties. We have thus, at the time of writing, over four hundred analyses of Alberta coal, made by the same analyst, and strictly comparable. These samples come from widely distributed points, some 88 townships being represented. The stream of samples is still flowing in, and it is hoped by the end of this year that the number of townships represented will be increased at least fifty percent. The time has arrived to publish some of the data collected; but it must be clearly understood that this is merely a progress report, subject to revision as further information is obtained. Three hundred and fifty-three coal mines in the province were operated during 1923. The production per mine varied from 5 up to 500,000 tons. With this number of mines to examine (and fresh mines are being opened every year) it is a large task to make even a proximate analysis of representative samples from every mine. Any chemist will appreciate the fact that to make ultimate analyses representative of even the larger mines will be a long and tedious task. It has seemed better to make a comprehensive survey by proximate analysis and determination of calorific value before beginning the more thorough survey by ultimate analysis. This paper, therefore, deals only with proximate analyses and calorific values; and, owing to limitations of time and space, does not deal with other chemical and physical characteristics of coal, such as storage quality and fusibility of ash, important though these are.

Iron ore, when subjected to reducing gases at a temperature suitable for reduction of the oxide but not high enough to melt the ore or metal formed, is converted into metallic iron. The product, being the original piece of iron oxide minus its oxygen, is sponge-like in appearance when viewed under a magnifying glass, and hence is called 'sponge iron. Sponge iron was probably the form in which some of the first iron was recovered from the ores. As early as the eighth century the Catlan forge developed into a low shaft furnace known as the high bloomary, in which iron was produced in the form of a pasty mass. These furnaces were increased in height, and with increased temperatures came the production of liquid cast-iron, at first undesirable because of lack of knowledge of methods for working it. In 1340 the first true blast-furnace was built iri Belgium. Some castings were made, but the greater part of the iron was converted into wroughtiron blooms by a crude puddling process. Charcoal was the universal fuel until the latter part of the seventeenth century, when coke was first used in England. Larger scale developments of methods of refining pig-iron followed. In I 885 Bessemer built his first converter in England, and within a few years the Siemen' s regenerative open-hearth furnace was developed, also in England, to produce steel. Then followed the enormous expansion in the metallurgy of iron. The idea of a direct process for the production of iron and steel has persisted during all of this time.

That the construction of the Pacific Great Eastern railway has not been accompanied by an immediate and great development of traffic is not due to lack of natural resources in the district traversed, but to conditions that have delayed their development. Prior to the commencement of construction of the railway there was no inducement to prospect for any other mineral than gold, on account of lack of transportation. The war began soon after the commencement of construction; diverting practically all capital that might have been available for opening up the country; and since the war, capital has continued shy of new investments. If the war had not occurred it is probable that prospecting and development would have been carried out concurrently with the railway construction. Moreover, much of the district is covered deeply with drift, marine and alluvial deposits, rendering prospecting for lode mines a more expensive and slower proceeding than can generally be undertaken by the ordinary prospector, without capital. On the other hand, the presence of large porphyry dykes, granitic intrusions, and the finding of rich float in places are indications that rich miIY.ral deposits probably exist in several localities in the Lillooet district, in the Cariboo proper, and also nearer the coast. Two or three mines producing the tonnage of the? Britannia would materially alter the earnings of the railway and pay interest on the bonds. There are, however, other possibilities, in addition to large metaliferous mines, in the non-metallic minerals of the district.

Introduction This paper describes some of the mineral resources that are tributary to that portion of the Pacific Great Eastern railway included in the Western Mineral Survey District, No. 6, of British Columbia. This district extends 38 miles northerly from Squamish, the ocean terminus of the railway at the head of Howe sound, to Alta lake. Beyond Alta lake the railway continues northerly through two other mineral survey districts: the Central Mineral Survey District No. 3, and the Northeastern District No. 2. District No. 6 includes that section of the Coast Range from which the waters flow southerly towards Howe sound. The division between District No. 6 and District No. 3 is represented by an imaginary line across the summit between the headwaters of the Cheakamus river, flowing south into the Squamish, and the Green river which flows north and empties into the head of Lillooet lake near Pemberton meadows, about 20 miles from Alta lake. History: - The history of the route of the P. G. E. railway dates back to the old Cariboo days when a pack-horse trail traversed the country northerly from Squamish to the Pemberton meadows, and also south-easterly from Squamish to the head of Seymour creek, thence southerly down that creek to the north arm of Burrard inlet.

The case of the P. G. E. railway is a peculiar one. Traversing, as it does, to a large extent, a mineralized country there are as yet no producing mines along its route although I am convinced that mines will be developed in the region tributary to the railway. The Fitzimmons group of claims, a copper property near Mons station, 37 miles from Squamish is now (unless recently relinquished) under bond to the Granby Company. On Cadwallader creek, in the upper Bridge river country, certain gold properties, referred to later, are being developed. Prospectors are fairly active in the Pemberton meadows area. There are also a large number in the Bridge river, Gun creek, and Whitewater districts. East of Marguerite station some development work is being prosecuted on some copper claims located there. In addition here and there throughout the entire route of the railway prospecting is being undertaken. At Hat creek, 15 miles from Pavilion station there is an enormous deposit of lignite. It is by no means certain that this coal can be profitably mined and hauled to the railway, but as a cheap fuel it offers possibilities in the recovery of by-products by destructive distillation. Logical procedure would ? indicate the expenditure of considerable money on development and, if results justify, the construction of a spur from the main line to the deposit.

A glance at the map discloses the fact that the Pacific Great Eastern railway either traverses or crosses some of the most important rivers of the province: the Squamish with its branches the Stawamus, Mamquam and Cheakamus; and the Green, Lillooet, Birkenhead, Fraser and Quesnel rivers. Each of these and some of their tributary streams, having their ?sources and upper reaches in the higher altitudes in regions of abundant snowfall, is capable in greater or less degree of furnishing water under suitable heads for the economic production of power. Beginning at its present terminus at Squamish the railway has the only hydro-electric development within its territory among the whole list of streams mentioned. A 225 horsepower installation at the edge of the East branch of the Squamish river, using water from Stawamus river, a branch of the former, under a head of 418 feet, is a modest beginning. Two or three additional sites, where water may be used under somewhat similar heads, may be found on this little stream. Next above Squamish, along the route of the railway, is the Mamquam, a long tributary of the Squamish from the eastern slopes. It has a drainage area of something like 130 square miles with widely varying discharges of from less than 50 to about 14,000 cubic feet per second. The preliminary investigations so far have disclosed no suitable storage sites, so the Mamquam may be regarded as a small continuous power stream - probably less than 1000 horsepower.

We are indebted to the Consolidated Mining and Smelting Company of Canada Limited for the several pictures in this issue showing the progress made in new construction at Tadanac and at Bonnington Falls, B.C. Plate No. 1 shows the down-stream side of the No. 1 hydro-electric station of the West Kootenay Power and Light Co. Limited at Bonnington Falls, on the Kootenay river, at which 17,500 k.v.a. will be developed to meet the requirements of the enlarged zinc and lead refineries at Tadanac. The generators, exciters and switch apparatus were supplied by the Canadian General Electric Company and the step-up transformers by the Canadian Westinghouse Company Limited. The plant throughout was designed, manufactured and erected by Canadians. Plate No. 2 shows the casting room of the new lead-plant and plate No. 3 the new tank-room of the electrolytic lead refinery at Tadanac. These additions will increase the capacity of the lead refinery by some 150 tons daily. The extensions also include practically doubling the zinc plant, and the gold and silver refineries. With the exception of the new stack, all designing construction and installation of the various plants is being done by the Company's own employees at Tadanac. Plate No. 4 shows the progress made in the construction of the new reinforced concrete stack at Tadanac. This stack, of 21 feet inside diameter at the top, will be brick lined and when completed will rise 400 feet above its foundations: the tallest of its kind in the world. The construction is in charge of the Rust Engineering Company of Pittsburgh, Pa. Plate No. 5 is a panorama of the Tadanac smelters and refineries. The photograph was taken from the roof of the lead smelter and gives an excellent idea of the size of the plant and its surroundings. Tadanac produces electrolytic lead, zinc and copper and fine gold and silver. During 1924 the company treated 1,333,523 tons of ore and produced: 161,400,- 769 pounds of lead; 92,197,824 pounds of zinc; l,382,750pounds of copper; 4,074,044 ounces of silver, and 26,976 ounces of gold.

Alberta is labouring, and has laboured, under serious difficulties in the marketing of ?her coals, due to a number of conditions which now obtain, but all of which appear capable of solution, and their elimination would insure a very largely increased market for the vast coal resources of that province. It is perhaps necessary to again mention the fact that 15 per cent of the world's coal resources are to be found in Alberta; 21 per cent of that of North America; 72 per cent of that of the British Empire, and 87 per cent of that of all Canada. While we talk largely of the great wealth of Canada, the immensity of her vast natural resources, it is axiomatic that the mere presence of any natural product in a country does not in itself constitute wealth for that country, unless these raw materials can find a market, either in their raw state, or by the process of manufacture. There are many factors, however, which enter into the marketing of any commodity. The chief of these, in my opinion, is price competition. High costs of production materially reduce the radius in which any product can be marketed, and this applies particularly to coal. Mining costs in the province of Alberta are necessarily high at the present time, due in a large measure to the ease with which the 'gopher hole' mine can be opened with small capital.

This paper describes the progresses used in the manufacture of steel wheel-centres, tyres and axles at the works of the Commonwealth Steel Products Co., Newcastle, N.S.W., Australia. The plant is adjacent to the Northern railway and consists of three main buildings, namely: the foundry, the forging and rolling shop, and the machine shop. The foundry contains a 6-ton Heroult electric furnace, together with all necessary mechanical appliances for moulding. Reheating furnaces, steam hammers and tyre rolling mill are installed in the forging shop. The machine shop contains lathes, boring machines, and hydraulic presses. Until this plant commenced operations all wheels used in Australia were imported, previ.ous to the war, from England and Germany, and latterly from England only. Besides being of great benefit to the country in that there is now a domestic source of supply of these articles, there is also the advantage of retaining the home market; and in addition, a small portion of the population are now engaged in highly technical occupations requiring a great degree of skill. The plant began to operate in October 1919, and by 1921 was in a fair way to meet the domestic demand for those articles of railroad equipment which it manufactures.

The battle of the gold standard is not limited to one country alone, or even to a single group of countries. It is being waged merrily in many important commercial and industrial quarters. Though it is not always a practical issue calling for immediate attention, it is none the less, quite widely, engaging the thought of bankers and other students of finance. The controversy arises, in the last analysis, because of the desire of men to secure a stable currency. There are two ways of restoring a reasonably stable currency system: (1) the re-establishment of the gold standard, or (2) the deliberate and artificial management of a paper currency. Both systems are well known. The gold standard was in use prior to the war in the principal commercial countries. A currency of inconvertible paper has been at times employed in the past in various countries; for example in Britain from 1797 to 1821, and in the United States from 1862 to 1879. The gold standard, as all are aware, implies the selection of gold as the standard of value. The unit of value is a fixed weight of gold and, so long as the standard remains unimpaired, all other means of payment are maintained at a parity with standard gold coins. And gold coins alone constitute the standard money, inasmuch as their value as bullion equals their value as coins. Under the gold standard this would not be true of any other form of money, although all other varieties of money, including bank notes, government notes and silver coins would be freely convertible into gold money. Strictly speaking, the gold standard also implies that the gold money in turn shall itself be freely convertible, through melting, into gold bullion and freely exportable.

Reference to the original use of the terms Laurentian and Huronian (and its extension), shows that the former was applied to granitized sedimentary and metamorphic pre-Cambrian rocks, and the gneissoid igneous rocks associated therewith, and the latter to non-fossiliferous rocks supposed to be later. But it appears from the work of Collins, Quirke and others that there is more or less of an overlap, and that of the original Laurentian the Grenville limestone, and some of the granites, may be later than the lowest part of the original Huronian. Before we can decide whether to abandon one or the other of the two terms, or how to delimit them, it is important to know the extent of this overlap. The Pb :U ratio, though not to be depended upon too minutely, does give a real idea of the age of a mineral as it increases with the decay of uranium, and so is greater the longer the time since the uranium was separated: and there are reasonable prospects of help there from in getting a knowledge of the relative age of different granites to assist in solving the problem, as facts already collected show. 1. Historical review of the use of the words Laurentian and Huronian: 2. Difficulty encountered: 3. Popular account of atomic disintegration: 4. Methods of estimating age by it: 5. Applications.

The northern part of the P. G. E. railway traverses and opens up that part of the province known as the Cariboo district, comprising the Cariboo and Quesnel Mining Divisions, which are a part of the Northeastern Mineral Survey District. Williams lake, a divisional point on the P. G. E. is near the southern boundary of the Quesnel Division and from this point the railway runs northerly to Quesnel, its present terminus. From Quesnel the railway is projected and partially constructed to Prince George on the Canadian National railway; therefore its general trend is northerly through the heart of the Cariboo district. Early History There is no need to outline at any length the early history of mining in the Cariboo. It is sufficient to say that the great gold rush to the Cariboo, in the early sixties, was practically the commencement of mining in British Columbia. These early placer mining operations centred around the old towns of Quesnel Forks, Keithley Creek, Barkerville and Van Winkle, the latter now called Stanley. Many millions of dollars of placer gold have been taken out and the end of production is not in sight yet. The maximum yearly production was reached about 1863, after which there was a gradual decline in output. During the war years production was at a very low figure but a steady, even if small, increase has occurred in the last three years and prospects are encouraging for a much greater output.

This little sketch of the late Willet G. Miller, Provincial Geologist of Ontario, is intended to be neither a biography of his career nor a eulogy of his life. His biography has already been written in an incomparable manner by Mr. T. A. Rickard, his eulogy by Canon Cody. What more can be said of Dr. Miller than is summed up in the words of that great Canadian divine, Canon Cody, that he was "Big in body, big in heart, and, as we learned, big in brain." This article, then, will merely record a few personal reminiscences of the man himself, and while they are necessarily disjointed, they may at least serve to illustrate certain traits in his character which are not generally known or appreciated outside of the circle of his intimate friends. In the latter part of May in the year 1904, Willet G. Miller, with two? assistants, set out for the small village of Haileybury to begin his geological work in the area a few miles to the south which he was soon to name Cobalt. At that time the Timiskaming and Northern Ontario railway was not finished, although the right-of-way was cleared and partly graded. The nearest railway station was on the Canadian Pacific at the south end of lake Timiskaming, from which point the old steamer Meteor carried passengers and freight up the long, narrow and deep waters of lake Timiskaming, a very pleasant trip of some sixty miles. On this particular trip there was a fairly large crowd on board consisting of settlers going into the clay belt north of lake Timiskaming, of lumbermen, and of a few merchants and commercial travellers who were interested in the small business centres of Haileybury, New Liskeard and Ville Marie. Scarcely any attention was paid to the reports of the newly found silver deposits, although the daily papers had announced discoveries in the district six months before. As a matter of fact, the chief excitement on board was afforded by a moose, which, in swimming from the Ontario to the Quebec shore of the lake, crossed the bow of the boat, the captain steering to within a few yards of the terrified animal.

From the view point of the mining engineer, the square-set method of stoping as practised at Butte, Montana, is one ?of the outstanding features of well conducted mining operations in that camp. The following information was obtained in the course of two months underground work in the Granite Mountain mine, during the summer of 1920, which is one of the properties of the North Butte Mining Company, situated on the well known Speculator vein. Most of the information was derived from personal observation and from discussions with various miners and with members of the staff. Geology The copper mining area of the Butte district is some two miles long by one and a half miles wide, a mineralized area in a great batholith of monzonite granite, locally known as the Boulder batholith. This extensive body of granite is traversed by several series of mineralized fault-fissures which differ in strike but generally dip steeply. Geologists agree that following the formation of the fissures, alkaline solutions ascended and decomposed the felspathic portions of the granite in the immediate vicinity of the fissure walls, and that these alkaline solutions were followed by cupiferous solutions which filled the fissures and replaced the granite next to the walls. A zone of oxidized ore, varying in thickness from 10 to 400 feet, overlies a sulphide zone containing chalcocite, enargite, bornite and chalcopyrite, with a small amount of quartz gangue. The veins are from 3 to 100 feet in width and contain, on the average, 3 per cent of copper, 2 ounces of silver, and 15 cents in gold per ton.

This paper is in the nature of a protest against the dangerous propaganda afoot for the prevention of new mining undertakings and which is based on the imaginary 'blue ruin' conditions supposed to exist in the industry. An article by Mr. G. R. Pratt, A.M.E.I.C. in the first issue of the Western Canada News, February 2nd, 1925, and entitled "Review of Coal Mining in Alberta", is an excellent example of this type of propaganda. The article is a tissue of misstatements, faulty deductions and erroneous conclusions. For instance it contains the statement that some coal measures in Alberta are mined at great depth - whereas we all know that there is no coal mined at great depth anywhere in the province; another error is the classification of all mines under one head irrespective of whether they are mining prospects, 'country banks', or pukka mines equipped with railway facilities; and I believe that suppressio veri is tantamount to suggestio falsi. The bulk of his article hinges on a Table 1, which shows the details of coal produced in Alberta during 1923. Studying this table Mr. Pratt, in the manner of a conjurer producing rabbits from a hat, offers the following for the confusion of the public:- (1) "Waste effort, want of capital, waste of coal resources which result from unrestricted development"; the fact being that the waste is due to the failure of the Department of the Interior to exercise the powers which are inherent in the form of lease.

Canada is a very large country with a small population which is growing very slowly. We have great natural resources, but with our limited population we are continually looking afield for new capital to develop these resources. Our mining areas are among the most important fields offering opportunities for new capital and because of the wide-spread appeal which mining makes this industry commands a great deal of attention. While we are glad to see new capital from any source, we welcome it particularly from Great Britain, for, although we offer equal opportunities to the nationals of any country we would be glad to see the development of our natural resources financed as far as possible within the Empire. However, when we invite ne capital we must accept certain responsibilities, and while we have opportunities to offer, we should ask ourselves how these opportunities are taken advantage of and what sort of treatment the foreign investor receives.

The method of feeding blast-furnaces to be described below is simply the application of well-known principles, and an attempt to carry that application to its logical conclusion. It does not involve radical changes in equipment, nor does it require unusual skill on the part of the furnaceman. In fact, much of its value lies in its very simplicity. Before giving details of the method it will be well to consider briefly the conditions under which it was used at the Nickelton plant of the British America Nickel Corporation, in the Sudbury district, before that plant closed down. The Sudbury nickel ore consists chiefly of pentlandite, chalcopyrite and pyrrhotite in a gangue of norite or greenstone. The proportions of sulphide and gangue vary widely in different mines, the former constituting about 45 per cent of the total in the British America sorted ore. The gangue is fairly uniform in analysis, carrying about 55 per cent Si02, 18 per cent A120 3, 13 per cent FeO and smaller quantities of CaO, MgO, Na20 and K20. The ore has been frequently described as refractory, a word which seems suitable when one considers the many unsuccessful attempts to smelt it pyritically, as well as the high percentage of coke normally used at all the plants in the district.

Gypsum was first exploited as ?a commercial proposition in this province by the Union Mining Company which, in 1900 opened quarries on the east shore of Lake Manitoba, near the present site of Gypsumville. This company established a mill at the head of Portage Bay on the lake, and the manufactured plaster was carried by the companies boats to McArthur's siding on the Whitemouth river near Westbourne, Man., from which point it was distributed. In 1904 a reorganization took place and the Manitoba Gypsum Company Limited bought out the original company, and operated the original mill for about one year when it was destroyed by fire. There were many factors which rendered the operation of a mill at the quarries very difficult; lack of rail transportation for bringing in supplies, and the impossibility of local power development made manufacturing costs very high. Satisfactory distribution could not be affected because of water transportation and poor terminal facilities at McArthur's siding. For these reasons the new mill was built at Winnipeg, where cheaper power and better distributing facilities permitted the industry being placed in a better position. The company continued to bring the gypsum rock by steamer to Totogan, from which point it was transported by rail to Winnipeg. This period was one of steady expansion as the product became better known and more universally accepted as a wall finishing material. Unfortunately, in 1909, this new mill was destroyed by fire, causing a serious set-back to the company, at a time when the steady growth of the western market gave every promise of the industry being placed on a profitable basis.

In this section of the province only the most meagre of surveys have been made and because these are not sufficient to determine with any degree of accuracy even the total forest area, the information presented in this paper is not complete. Area: -The area south of the Canadian National, and served by the Pacific Great Eastern, is roughly 38,000. square miles, 30,000 of which is classed as productive. This is approximately equal to the productive area of Norway, or half of Finland-or of 30 per cent of Sweden. It is larger than that of either Nova Scotia or New Brunswick. Eliminating from the productive area 3600 square miles of grass-land and areas capable of agricultural development, 26,000 square miles (16,600,000 acres) remains as absolute forest-land, as compared with the 55,000,000 acres of Sweden, the 37,500,000 acres of Finland, the 17,000,000 acres of Norway, and the 7,600,000 acres of Austria.
