The United States of America has held the record of being the largest coal producing country in the world since the year 1899, prior to which date the greatest output was furnished by the United Kingdom. Since then, moreover, the production in the States has rapidly increased, until now it is approaching double the output of this country, the figures for the year 1913 being 504,520,000 tons and 287,410,000 tons respectively. Not- withstanding this, the exports from the United States have been comparatively small, whereas, of course, the exports from this country are high compared with the production. It may here be mentioned that the total exports of bituminous coal from the United States during last year were 14,413,000 tons, of which nearly 8| million tons represented supplies to Canada, whilst, of the balance, a million tons were consigned to Cuba, about 564,000 tons to the Argentine, 527,000 tons to Brazil, 392,000 tons to Mexico, and 343,000 tons to Panama. As regards European shipments, Italy called for over 1| million tons, and requisitions for Greece and Spain amounted to slightly over 100,000 tons for each country. These figures relate only to bituminous coal, the total export of anthracite during 1915 amounting to 3,682,000 tons, of which 3,621,000 tons were supplied to Canada. In comparing these figures with the previous two years, it is found that the total exports of bituminous coal have decreased, being 15,702,000 tons in 1914, and 16,083,000 By F. J. WARDEN-STEVENS, M.I.M.E., A.M.I.E.E., &c. 500ft. in width and 35ft. deep; the port of Newport News is near the mouth of James River at the north of Hampton Roads, whilst the port of Norfolk is at the south. The port of Norfolk includes Bewails Point, and Lamberts Point, which is situated further south, near the mouth of Elizabeth River. The distances to the Atlantic from Newport News is about 28 miles, from Lamberts Point about 27 miles, and from Sewalls Point about 22 miles. The ports of Newport News and Norfolk are both in the State of Virginia, and serve for the shipment, from the Western Virginian fields, Of the well-known New Rivenand Pocahontas bituminous coals, the best seams of which produce the highest grades of steam coal available in the United States, and compar- able with the Welsh steam classes of this country. The average analysis of New River coal shows 76 per cent, fixed carbon, 18 per cent, volatile and 6 per cent, ash, with a heating value of 14,800 British thermal units, the average analysis of coal from the Pocahontas seams being almost similar, with perhaps slightly lower vola- tile and higher ash contents. A third coal field adjoining is the Kanawha, which produces a coal with a higher volatile content averaging about 33 per cent. Newport News. About two-thirds of the total tonnage dealt with at Newport News consists of bituminous coal, the ship- steel, hopper type electric transfer cars of 100 tons capa- city, thus providing for the contents of two wagons of 50 tons capacity, or one of 100 tons capacity. The weight of these transfer cars is recorded automatically while passing over track scales when they leave the dumper. They are then elevated, by electric hoists, to the pier deck—a height of 90 ft. above low water level. From the elevators these cars pass on to rail tracks, and travel along the pier deck to one or other of a series of bins, where they are discharged. At each side of the pier, beneath the deck, there are 33 of these bins, situ- ated 30 ft. apart, each of which has a capacity of 110 tons. The equipment is in duplicate, there being two car dumpers and two hoists, one for each side of the pier, and the combined capacity totals 6,000 tons per hour. There is a depth of water at the pier of between 33 ft. and 36 ft. at low tide, and as the average variation of tide is only 2| ft., large vessels can come alongside the pier for loading cargo or bunkers, and several vessels can be loaded at once. The hoppers serve a length of 1,000 ft. on either side, and allow of loading into all the hatchways or ports of a vessel at the same time by means of adjustable chutes connected with the bins. Sewalls Point. Concerning the port of Norfolk, the Virginian Railway serves the coaling piers at Sewalls Point, and the Nor- folk and Western Railway the piers at Lamberts Point. At Sewalls Point there is a steel and concrete trestle pier of 1,045 ft. in length, with a deck 65 ft. wide, at an elevation of from 69 to 76 ft. above water level at high tide. There is a rail track on the deck of the pier at both sides for the loaded cars, which serve 31 hoppers of 60 tons capacity on each side, and a central track is .g;, L-. tons in 1913, thus indicating that the European war con- ditions affecting coal supplies have not been to the advantage of the total coal exports from the U.S.A. Whilst the State of Pennsylvania has by far the greatest output, and produces nearly one half the total coal raised in the United States, Western Virginia ranks second in this respect, and produces the classes of steam coal in most demand for oversea export and bunker supplies, in competition with the Welsh steam coals of this country. A considerable proportion of the coal has, of course, to be railborne long distances, and Western Virginia coal provides the largest railway mile tonnage of any of the bituminous coal fields, although the pro- duction is only about one-half of the production of bituminous coal in the State of Pennsylvania. A reference to some of the principal coal shipping ports of the United States is at the present juncture opportune, a,s it is doubtless the intention of that country to extend the oversea markets for its coal, and the Panama Canal is, of course, expected to aid that object considerably. Hampton Roads. It is proposed to refer first to the Hampton Roads ports, which have come into prominence on account of the facilities now afforded for coal shipments from the Western Virginian coal fields. Hampton Roads claims to be the largest coal shipping centre on the Atlantic coast, providing important railway terminals for coal traffic and modem coal shipping equipment, enabling some twenty vessels to be loaded at one time. Hampton Roads are entered from Chesapeake Bay, on the Atlantic Coast of the United States, about 165 miles south of Baltimore, there being a deep-water channel Coal Shipping Pier and Lifts at Newport News. ments of which during 1913 amounted to 3,061,000 tons; and this quantity was increased during 1914 to about 4,000,000 tons. The coal is railborne from the mines, an average distance of about 400 miles, by the Chesapeake and Ohio railway, in train loads of about 5,000 tons, and the storage siding tracks at the port amounting to 72 miles in length, are capable of accom- modating no less than 4,000 railway wagons. To give a further indication of the extent of the coal traffic it may be mentioned that the above-named railway company possesses about 36,000 wagons for coal, many of which are of large capacity—50, 75, and 100 tons; and, in fact, the whole of the New River coal tonnage shipped from Newport News is conveyed over the Chesapeake and Ohio railway. There are five piers at Newport News equipped especially for coal shipments, the smallest of these piers being 342 ft. in length and 45 ft. wide; whilst the largest, which was completed as recently as 1914, is 1,200 ft. long and 67 ft. in width. All these piers are of the elevated trestle design, the older ones being of timber and pile construction; but the latest is con- structed of steel and is supported on concrete pillars. It should be stated that this newest pier is now almost exclusively used, owing to the special equipment pro- vided, which allows for rapid loading and, therefore, quick despatch. As an example of this, it may be mentioned that 7,469 tons were loaded in 2| hours, of which about 200 tons represented bunkers—an average loading speed of over 2,700 tons per hour. It will be of interest to briefly refer to the arrange- ment and equipment of this pier. The railway wagons gravitate from the service sidings to an electrically- operated car dumper, whereby they are discharged into available for the return of the empty cars. The equip- ment provided for this pier includes a car dumper, the cradle of which will take railway wagons 50 ft. in length. This dumper is operated electrically by two motors, each of 130 horse-power, and is provided with another motor, of similar power, for hauling the loaded wagons up the inclined approach track into the cradle of the dumper. The dumper discharges the wagons into transfer or pier cars, which are of the hopper type, and have a capacity of 60 tons. There are 10 of these transfer ears, all electrically equipped with two motors for travelling, the electricity being taken from an overhead trolley wire system on the pier deck. The operation of the hopper doors and the brakes of the cars are effected by an air compressor on the car, and they are controlled from a driver’s cabin at either end for travel in both directions. The transfer cars from the dumper approach the pier by an inclined track with a gradient of 1 in 4, instead of being raised by lifts as in the case of Newport News. After leaving the dumper, the loaded cars are weighed automatically while gravitating over a track scale, and are pushed up the inclined track by a track trolley operated by an electric haulage winch. They then travel electrically along the pier, and are dis- charged by their hopper doors into the bins, which, as mentioned, are operated by compressed air, there being four doors, which can be opened and closed either inde- pendently or together. These transfer ears, when dis- charged, travel on the central track, and gravitate by way of another but longer incline of slighter gradient back to the dumper for another load. Connected with each of the bins on the pier is a hopper, which is capable of vertical adjustment in elevation, having a range of
