FLIGHT, AUGUST 17, iy;*3 BOOK REVIEWS " The Modern Diesel," a Review of high-speed Com pression-ignition Engines for Road Transport, Aircraft and Marine Work. Published by Iliffe <~ Sons, Ltd. Obtain able from FLIGHT Office. Price 3s. 9d., post free. ""THE second edition of this book is an improvement on *• the first in that an opportunity has been taken to supplement the particulars and illustrations with those relating to the latest types. The 194 pages of the book contain 130 illustrations, and the whole subject of the work ing of the Diesel type of engine is dealt with in a manner which is equally far removed from the " popular " and the " high-brow." The result is that the book can be read and understood by almost anyone, certainly by any reader with a slight knowledge of the principles of ordi nary car-type petrol engines. At the same time, even those who can claim more than an elementary knowledge of the working principles of the compression-ignition engine will find this book worth buying, as it gives particulars of a considerable number of engines as used in road and marine transport, and of several compression-ignition aero engines. The book begins with a brief historical review, giving the origin of the compression-ignition engine, and gives an account of the two " schools " of design, Diesel and Akroyd-Stuart. The fundamental principles of operation Lire described, and explained by simple diagrams, and the importance of the fuel injection pump is well brought out. Of greatest interest to FLIGHT readers may be assumed to be the section which deals with compression-ignition aero engines. The types described arid illustrated include the Beardmore " Tornado " and flat horizontal 12-cylinder engines, the Bristol " Phoenix," the Clerget 9- and 14- cylinder engines, the Fiat, the Junker " Jumo IV " and " Jumo V " (the latter somewhat incompletely), the May- bach, the Packard and the Rolls-Rovce " Condor." " Airsense," by W. O. Manning (Sir Isaac Pitman cr- Sons, Ltd.). Obtainable from FLIGHT Office. Price 3s. H)d. post free. 1V/IK. MANNING, well known as one of our early ivl designers, has produced a book for which many people have been waiting. It is just the sort of volume which we all want when we are asked the why and wherefore of flying by the younger generation, and, indeed, even by those of more mature years who are for the first time taking an interest in flying and want to get a clear idea of what an aeroplane is and how it works. The language is clear, concise and simple, and the mean ing is therefore plain to everyone, but—and this seems a rather big "but"—it would have greatly enhanced the value of the work if there had been included in it a larger number of diagrams and illustrations. Words, however well and correctly used, cannot make any semi-technical description as clear alone as when they are accompanied by a diagram. No doubt questions of cost have been responsible for this paucity of illustrative matter, but there is a definite danger that Mr. Manning (for his publishers) have been " penny- wise and pound foolish." However, in spite of this, no one will feel that they have anything but good value for their money. Apart from actual aeroplanes and flying, there are six chapters devoted to explanation of the petrol engine and how it works, also very valuable for " explanatory purposes. In a chapter on " Wings that Rotate or Flap Mr. Manning has, perhaps, not brought out the great advantages already obtainable with that type of flying machine as much as he might have done; he has rather stressed the limitations. Incidentally, " Autogiro " is the name of Sefior de la Cierva's flying machine, not autogyro. It is to be hoped that those innumerable people who write to FLIGHT asking " how and why " will in future save us a great deal of work by first getting a copy of this book. § s TWO FRENCH MEETINGS A Rallye International has been organised by the \ ichy Aero Club to take place during the forthcoming week-end. Only those who arrive between 3 p.m. and 5 p.m. on Saturday, August 19, will be regarded as taking part. The programme which has been arranged—only those pilots who sent in application forms before August 10 will be guests of the Club—includes an Air Meeting on the ^unday, at which M. Pierre Cot, the Minister for Air, will preside. In the evening there will be a Grand Banquet given by the town of Vichy and the Aero Club. \ isitors will depart on the Monday. Customs will have 1 be cleared at a recognised customs aerodrome as no facilities exist at Vichy. Hangar accommodation cannot guaranteed, and visitors are advised to bring their rt ii pickets and cockpit covers. Those who are guests >t the Club will receive, besides hospitality, a contribution towards their travelling exnenses. travellin expenses £3 "Hie French Air Transport Merger ACCORDING to The Times Paris correspondent the tuidation of the Aeropostale Company has been completed the sale of the company with all its assets, including s organisation, aircraft, ships, contracts, and aerodromes * ranee, Africa, the Cape Verde Islands, and South - lerica, to the new company which was recently formed •-meter the auspices of the Air Ministry to acquire all the "oldl ^r HneS' The Price is 77'000'000 f- (£616,000 V l° paid in 15 equal instalments, beginning on F 1934.

There was no discussion Bienvenue Aerienne is the title given by the organisers, whose address is 6, Rue Galilee, Paris, to aerial week, intended to be a return for hospitality shown French aviators abroad on many occasions. It is planned to take place during the week September 17-24, and will be in the form of a leisurely tour, with plenty of time for the social side. On September 17 visitors are asked to arrive at Rheims about 3 p.m. On September 18 they will fly to Orly, on September 19 to Buc, on September 20 to Lyons and Cannes, and on September 24 visitors will return from Cannes to their respective homes. On the arrival at Rheims visitors will be given tickets which entitle them to free hotel accommodation and petrol. British flying folk are asked to write as soon as possible to the address given above, stating the names and number of occupants in the machine, the registration letters, and the make and power of the engine. § § 5 at the meeting, and 13,224 votes, representing about 170,000,000 f. of capital, were given for the sale. All the pilots of the Air Union and the other French air lines will be " pooled " when these companies are amalgamated on September 1, so that every one of them will eventually be competent to fly any liner on any route now served by the constituent concerns of the new combine. In order to become thoroughly conversant with all the details of the different services at present under taken by Aeropostale, Air Orient, Cidna and Air Union, individual pilots, all of whom are fully-trained navigators and have several thousands of hours flying experience, will work in company with a colleague who is already familiar with the routes and conditions of the services concerned. Thus, a cross-Channel navigator will work with and under a pilot who has had long experience of the far-eastern route on a plane travelling to India, and vice versa. In this way, every pilot will in time be able at a moment's notice to take control of any 'plane of the amalgamated services. 837
