By five o'clock, every passage in the Grand Palais was nothing but a solid phalanx of humanity, and to pet about visiting the stands independent of the gentral movement of the crowd was almost a sheer impossibility. As was only natural to expect, most of the prominent French aviators were there. On f ntering the Grand Palais one is immediately struck with the magnitude c f the uniform decorative scheme. Under the central dome of the building is hung a huge light cloth bearing the mono gram of the exhibition, and radiating on all sides are brightly coloured hangings, each stand having its double name banners. The scene at night with the lights full on is ready magnificent. As for the aeroplanes themselves they were particularly noticeable for the excellence of workmanship that was evident in their con struction. Monoplanes were more in preponderance than ever, there being 29 as opposed to the 14 biplanes on exhibition. Verily the mono plane seems to be heading its double-decked rival for we see Farman, Sommer, and even Paulhan, once three of the greatest adherents to the biplane type, exhibiting rionoplanes. With the biplanes, only four retain the disposition of the engine to the rear of the pilot, and these are the products of Maurice and Henry Farman, Roger Sommer, and Voisin. The remaining ten of the biplanes are of the engine-in-front type and consist of the machines of the following firms:—Albatroswerke, Astra, Breguet (2), Caudron, Clement Bayard, Goupy, Savary, Sloan, and Zodiac. It is interesting to notice the growing popularity of the fuselage as the central unit in the obstruction of biplanes. Of the 14 biplanes at the Salon, 9 incorpoiate the use of this feature in construction. These include the names of those firms mentioned above as repre senting the engine-in-front type of machine, with the exvption of Savary and Caudron, and wiih the addition of Voisin, who is showing his Canard. With reference to the form of the bodies themselves there is a decided tendency in favour of bodies of the torpedo type, a feature that was foretold in these pages two or three months ago. It is rather surprising that the advantages of this type, as concerns the reduction of head resistance, have not been seen before, but now that Tatin and Paulhan have jointly demonstrated that, using a body of approximately streamline form, and paying due attention to the subject of reduced head resistance, it is possible to attain speeds in the neighbour of 80 miles an hour, we may confidently expect this type to gain great popularity. All-steel construction is also coming steadily into favour, eight machines now representing this type of construction, viz., Breguet, Clement Bayard, Morane-Saulnier, Porche and Primard, R.E.P., Sommer, and Train. Of these seven, Sommer and the Morane- Saulnier combination have been converted to belief in the advantages of all-steel construction since the last A«ro Salon in Paris. The Ponche and Primard monoplane is, with the exception of the main skids and propeller, constructed entirely of metal. Even the steel skeleton of the wings is metal-covered, sheet aluminium being em ployed. Steel, as is already known, plays a considerable part in the construction of both the Nieuport monoplane and the Voisin Canard. One very curious feature al out the landing chassis of this year's machines is that, in those which miy be classed as close copies of 140 1,000 90 900 70 90 900 900 900 96 900 140 1,200 160 1,200 160 1,200 1101,100 2601,300 140 1,250 140 1,30 1301,250 130 1,250 1301,250 1301,250 160 100 no 170 180 290 no 150 210 78 100 135 160 75 90 115 •45 8,000 14,000 5,000 8,500 10,500 12,000 17,000 12,000 14,000 20,000 11,500 10,000 13,000 18,000 4,500 7,500 10,500 15,000 The 14»cyl. 140-h.p.
