JUNE 18, 1925 AIR WORK IN CANADA IN previous issues of FLIGHT we have given certain informa-tion in connection with the splendid work done by aircraft in Canada, especially as regards that very important branch,Aerial Survey—one of those spheres of activity in which, to our way of thinking, aircraft is particularly fitted and shouldbe utilised to a far greater extent than it has up to now. This week we are able to publish, thanks to the courtesy ofNatural Resources, Canada " (published by the Canadian Department of the Interior), some notes on Canada's 1925programme of aerial activity. The programme of flying operations to be carried out during the coming season forthe Forest Branches of the Government's service by the Royal Canadian Air Force, was drawn up at a recent annualinter-departmental conference on flying operations, held at Ottawa. This Conference was held under the chairmanshipof the deputy Minister for National Defence and representa- tives from twenty branches of the Dominion GovernmentService were present. It was announced that some thirty-three aircraft would be available for civil Government operations,distributed at the various stations, as follows :—Dartmouth, N.S. Air Station, 2 ; Ottawa Air Station, 4 : Manitoba area,16 ; High River, Alberta, Air Station, 7 ; and Vancouver Air Station, 4. One or more aircraft in each section will befitted out for aerial photography. The growing importance which aviation is assuming incarrying on the work of the various branches of the Dominion Government's service is shown by the increasing demandson pilots and equipment in the Royal Canadian Air Force. As in the past, the work of the Department of the Interioris the largest item on the programme. The plans for 1925 show extensive work for the Forestry, Topographical Surveys,National Parks, Water Power and Reclamation, International Boundary Commission, and Ordnance Land branches of theDepartment. In the programme which we outline herewith, the photographic work for the coming session is a remarkableincrease over the work done in 1924, when 40,000 sq. miles were covered by aerial photography. The 1925 programmeprovides for at least double last year's area. The major part of the photographic work will be done for the Topo-graphical Survey Branch of the Interior in connection with its aerial surveys. The actual mapping is under the Topo-graphical Society. Forest patrol work has also been extended by the advantage of a new sub-station near The Pas to servethe west part of Northern Manitoba and by the inclusion of the northern part of the Clearwater Forest reserve in westernAlberta in the area to be patrolled. Considerable progress has been made in perfecting organisa-tion and developing equipment which will ensure maximum efficiency in forest fire protection at costs within the economicmeans of the Forest authorities. The Royal Canadian Air Force and the Dominion Forest Service are devoting all their energies to this end. The details of the coming session'sprogramme are as follows :— The Department of Agriculture.—Investigation of the upperatmosphere in connection with the spread of wheat rust diseases ; continuation of work on white pine blister rustcontrol. Department of Customs.—Patrols for preventive purposes.Department for Indian Affairs.—Transportation for parties- paying Treaty money in Northern Manitoba.Department of Fisheries.—Fishery patrols in Northern British Columbia.Department of Mines.—Vertical photography for mapping an area north of Georgian Bay.Department of Public Works.—Photographic survey of the Portland Canal, B.C.Department of Railways and Canals.—Photography of Hudson Bay Railway line and Churchill River District.Department of Interior, Photographic Surveys.—Vertical photography for mapping Windsor, N.S., and Fredericton,N.B., sectional sheets ; oblique photography for mapping counties Annapolis, Queens, Kings, Lunenberg, N.S. ; verticalphotography of Three Rivers, Quebec, and Kitchener, Ontario, sectional sheets, and of areas in the upper Gatineau water-shed and the Rouyn mineral areas, Quebec ; oblique photo- graphy of the Churchill River from Fort Churchill, Manitoba,to Pakkatawagan ; completion of oblique photography in The Pas mineral area ; extension of previous photographicsurveys in Ontario and Manitoba ; photography for the com- piliation of Battleford, Victoria, Fort Assinibione, Peace Hills-and Red Deer sectional sheets. Forestry Branch.—Photography over forested areas inMaritime Provinces ; vertical and oblique photography of the Peatawawa forest reserve ; patrols for the detection andsuppression of fires over the forested areas surrounding Lake Winnipeg and Lake Winnipegosis ; continuation of the airpatrols of the Crowsnest, Bow River and Clearwater forest reserves.Canadian National Parks.—Photographing historical sites in Maritime Provinces, Ontario, and Quebec ; fire patrol forWaterton Lakes, Rocky Mountains and Kootenay parks ; photographic reconnaissance in unsurveyed portions ofJasper Park area. Water Power and Reclamation Service.—Photographs oipower sites in Nova Scotia, New Brunswick, Ontario, Quebec, and British Columbia.International Boundary Commission.-—Photographing of International Boundary in southern Manitoba and southernAlberta. Ordnance Lands Branch.—Aerial surveys of the Rideau canal. From the above, it will be seen that they are going to be pretty busy in Canada from now on. CERRIC ALTHOUGH we have referred on previous occasions to the" Cerric " cellulose enamels and other products manufac- tured by Cellon (Richmond), Ltd., of Richmond, Surrey—the makers of the world-famous " Cellon " aeroplane dope— we rvould like to draw our readers' attention once again tothese " Cerric " products, for we understand that they are now attaining a high degree of popularity, not only in theaviation world, but especially in the motor-car industry. " Cerric " products, we need hardly remind our readers,consist of black and coloured " enamels" and lacquers belonging to the cellulose family; they are, in fact, anapplication to general uses of the process of doping, so important in aircraft production, having been developed fromthe various properties of the cellulose solutions employed in the manufacture of " Cellon " aeroplane dope." Cerric " enamels differ from ordinary enamels—and to some considerable advantage—in that they do not need" stoving," can be applied very rapidly and evenly by spray, dry very quickly, and are unaffected by oil, petrol, etc.,materials treated with " Cerric " being readily washed. Very much the same applies to the lacquers, which give aparticularly fine finish to metal parts. We may say that " Cerric " is now being largely used inconnection with aircraft construction, being particularly suitable for cowlings and all other metal parts, as it protectsthem from the atmosphere, petrol and oil, etc. The coloured enamels can also be used for treatment of the inside ofcockpits, cabins, etc., especially when it is remembered that oil and petrol will not cause any ill effects and that they takeand " enjoy " a wash and polish—in fact, the more you polish the better. This is a great advantage in the case of the woodsolutions (which replace French polishing and varnish) gener- ally used for instrument-boards, ply-wood parts, etc.The rapidity of spray application of the " Cerric " materials and the short time required for drying have made themparticularly suitable for aircraft work, as they accelerate output to a very large extent. We understand that Cellon,Ltd., are now meeting with a very steady demand for motor- car finishes in " Cerric " and already a number of firms haveinstalled spray plants for these materials. For those of our readers who require their cars repainted and wish to givethis type of finish a trial, we may say the following firms are in a position to undertake this work :— Messrs. Mulliner and Co., Bedford Park Works, Chiswick,London, W. 4. ,, Carolus, Ltd., 12, Orsett Mews, Gloucester Terrace,London, W. Union Motor Co., 36, Ethelberger Street, Battersea, London, S.W.,, Birming Car Painting Co., Station Works, Station Road, Northfield, near Birmingham.Rapolac Co., 12, Kelvindale Lane, Glasgow. Of course, for domestic purposes there is practically " noend " to the uses to which " Cerric " may be applied to great advantage. 378
