CATALOGUES AND PRICE LISTS RECEIVED. We have received from Messrs. Robert Hudson Limited (Gildersome Foundry, near Leeds) a catalogue of colliery and railway plant, listing a large variety of specialities. The British Aluminium Company Limited (109, Queen Victoria-street, E.C.) have just brought out a new edition of their attractive pamphlet on electric power transmission, which deals in an informative manner with the employment of aluminium conductors. Amongst the new matter is a table of safe currents for overhead aluminium lines, calcu- lated on Forbes formula, giving a maximum temperature rise of 50 degs. Fahr, and 100 degs. Fahr, in still air; and matter dealing with line regulation, erection, scrap value, etc. To those interested in the subject this booklet will be found really useful. Messrs. E. A. Reed and Company Limited (14, Victoria- street, S.W.) have got out a new’ catalogue of elevating and conveying machinery, etc. Amongst the specialities shown are lattice-braced bucket and inclined steel tray conveyors (these are fitted with bushed roller steel chains, with lubri- cators fitted to all the pins); shaking conveyors and screens, with eccentric drive and balancing device; push-plate con- veyors, fitted with self-lubricating side rollers; hand con- veyors of various types. A hand-propelled tripper is shown, and these are arranged also for power drive, whilst in cer- tain classes of travelling trippers the motion is communicated from the belt itself. Messrs. Reed are makers likewise of gas works, mining, and contractors’ plant, including coke breakers and screens, vertical pumps, valves, and structural work generally. The Consett Iron Company Limited (Consgtt, Co. Dur- ham) send us a circular setting forth the advantages of corrugated steel crowntrees as a substitute for timber in mines. These crowntrees, it may be noted, are being used at the company’s own collieries. Any length can be rolled, with a variation in thickness of in. to f in. The usual size is 6 ft. long by 5 in. wide by A in. thick; of this size there are about 60 to a ton. Thus it is calculated that the net cost at £7 per ton, debiting the value as scrap if recovered, is Is. 6d. each. It is reckoned that a steel crowntree should have a useful life of two or three times as long as a timber one, and, taking into account the saving in the cost of labour in setting, a considerable economy can be anticipated by the use of steel. The makers, it may be added, will send sample lots for trial. Messrs. Siebe, Gorman and Company Limited (of 187, Westminster Bridge-road, S.E.) have sent us a new cata- logue of rescue apparatus. This covers a wide range of smoke helmets, self-contained oxygen breathing apparatus, resuscitating apparatus, etc., and shows how the call for such appliances can be adequately met in this country. Of the “Proto” self-contained apparatus, it is only necessary to say that each succeeding modification has added to its simplicity, safety, and commodity. One feature alone—the dependence upon positive pressure—has commended it to many users. Variations are described in the one-hour type specially designed for the London Fire Brigade, and the “ Salvus ” self-rescue apparatus, which has been evolved for enabling miners who may be trapped after an explosion or fire to make their way in safety to the pit shaft. Many mining engineers have a strong predilection in favour of the hose type of apparatus, especially for combatting gob- fires, and here again Messrs. Siebe, Gorman and Company have expended the wealth of their experience. Their latest smoke helmets are blocked out of best raw hide. They are fitted with strong mica window’s in aluminium hinged frames, or fixed round goggles, and with air inlet connections and valve for escape of excess and vitiated air. A simple arrangement inside the crown adjusts the helmet to suit all sizes of heads, and a flexible leather extension, which is tucked under'the wearer’s coat or vest, effectually seals the lower part of the helmet. An ample supply of air is delivered by special double-acting bellows through air tube—asbestos covered if necessary—having embedded wire or armouring and metal couplings. The tubes are not attached direct to the helmets, but to waistbelts, thus preventing pull. Any of the helmets can be fitted with telephone or speaking apparatus. The bellows again may be worked from the waist or on the ground, or a rotary pump or blower may bo used instead. One interesting pattern is also furnished with a signal horn and a safety lamp fed with surplus air from the helmet. In place of the latter, a full or half-mask may be supplied. The catalogue illustrates besides a variety of other appliances and accessories, such as oxygen meters, high-pressure pumps for charging cylinders, com- pression pumps, animal air tester, etc., electric and oil safety lamps, resuscitating apparatus, diving apparatus, respirators, goggles, first-aid outfits, analysis apparatus, etc. Immingham Coal Exports.—Returns for the week ending November 13 show that the coal exported from Immingham consisted of the following shipments :—Foreign : To Aalborg, 1,437 tons; Aarhus, 1,442; Alius, 2,011; Bergen, 1,529; Gefle, 3,965; Harlingen, 1,432; and Oxelosund, 2,252. Coastwise : To London, 2,575 tons; and Poole, 2,390 tons, making a total of 14,068 tons foreign and 4,965 tons coastwise, against 29.171 tons foreign and 1,750 tons tons coastwise during the corresponding week of last year.

The Safest and Most Reliable Means of reviving persons apparently asphyxiated is to administer Oxygen by a simple form of apparatus, as shown, and at the same time use the Schafer method of resuscitation which is known to all St. John Ambulance and Red Cross Students.
