MAY 18. 1922 Photographic Surveys of St. Croix River, N.B.—Vertical and oblique photographs of portions of the St Croix River, which forms the International Boundary between the Province of New Brunswick and the State of Maine, were undertaken by seaplane from the Halifax Air Station on behalf of the Inter national Boundary Commission. Sections of the river in the vicinity of St. Stephen, Oak Bay and Milltown were covered, and proved of value to the Commission, as they reproduced exactly all natural features, and supplemented the surveys already made by their engineers. We could mention a number of other examples of the way in which Canada is making use of the seaplane, but sufficient has, we think, been said to indicate that not only the Canadian 13 B Air Board, but a very great number of other Canadian Government Departments are fully alive to its possibilities. Comparison with the attitude towards the seaplane at home leaves one with a feeling that all is not well. We willingly grant that Canada has facilities and possibilities which do not exist in England, but a very great deal might be done towards a greater utilisation of the seaplane than is the case, even if the purposes for which it was used were somewhat different. But that is another story, to which we may return at a later date. In the meantime, we congratulate Canada on its energetic Air Board, and on its other progressive and wide awake Government departments. They have provided us with an excellent example to follow. H 13 A NEW GAS FOR AIRSHIPS ACCORDING to our American contemporary Aerial Age, the new gas for airships, " Currenium," which has been dis covered was demonstrated recently at Los Angeles. This gas possesses a lift about equal to hydrogen, and has non- inflammable and non-explosive qualities which should render it a valuable asset in connection with airship work. It is a manufactured gas, and can be produced in any quantity by an electrolytic process at an estimated cost of $30 per thousand cubic feet, $100 less than it costs to produce helium. " Currenium " has been developed by Dr. Edward Curran, head of the research department of the International Trans portation Co., of Los Angeles. It is the result of several years of research work on the part of Dr. Curran, who produced the gas successfully in 1918, since when he has continued the development of the process, and has succeeded in producing a 100 per cent, purity gas. As a result a new company has been formed known as " Airway Load Carriers," a combina- tioa*of the International Co. and the Hall Aeroplane Co., and both the new gas and the Hall " Helicoidal " propellers will be put to practical use. The new gas weighs 6.2 lbs. per 1,000 cubic ft. at a baro metric pressure of 30 ins. and a temperature of 400 F. Its lift under these conditions is, therefore, 73.8 lbs. per cubic ft. In the demonstration, previously referred to, made by Dr. Curran a flame was passed through the gas and an electric spark inserted in it without occasioning fire or explosion. The purity was allowed to drop below 80 per cent., with similar results. A small elongated balloon was filled with " Currenium " of low purity, and a flame applied to the end of the balloon. The gas did not explode, and the balloon was only burned where it came into contact with the flame— the gas escaping through the hole thus made. Under certain conditions of extremely low purity—which would never be allowed to exist in aircraft—it was found possible to unite " Currenium " with oxygen and air, and cause a flame, but without explosion.

By using this air service the passengers will save at least five hours in the journey to and from Paris. For passengers arriving at the French port from New York a motor-car will be waiting and will proceed to the aerodrome, from which they will fly direct to the capital. Outward- bound passengers from Paris will be able to arrange for an aerodrome motor-car to call for them at their hotel. It is possible to take a certain amount of baggage. 283
