last forced landing the machine was slightly damaged, andhad to be brought back to the Tempelhofer Aerodrome by road. By the evening of Sunday, May 31, no machinesof Class A had returned, while nine Class B machines had completed the circuit, and six of Class C. The fastest timein the 40-80 h.p. class was made by Billik on the U.10 in 9 hrs. 14 mins. The best time of the day was made byUngewitter on an Albatros L.69 with 100 h.p.' Siemens engine, covering 600 miles in 9 hrs. 4 mins. The first machine toreturn on Monday, June 1, was the little twin-engined Daimler L.21, piloted by Lorzer. The little Darmstadt" Mohamed " with Blackburne engine also covered the complete circuit. Second Circuit (June 2-3)The second circuit in the Rundflug was the longest in the competition, measuring no less than 1,130 km. (705 miles).Forty machines started on this circuit, and two crossed over to it from the first circuit, which they had abandonedon the way. The following machines (engines shown in parenthesis) completed the second circuit in the times given :Albatros L.69 (Siemens 100 h.p.), 10 hrs. 14 mins ; TIdet U.10 (Siemens 80 h.p.), 10 hrs. 56 mins. ; Udet U.8 (Bristol"Lucifer" 100 h.p.), 10 hrs. 10 mins.; Albatros (Siemens n des Berliner Hughafens \ TunpelhoTer Ftld This outline diagram shows the location of theTempelhofer Aerodrome, Berlin, and gives an excellent idea of the central position.

Third Circuit (June 4-5)Thirty-two machines started on the morning of June 4 on the third circuit of the German Rundfiug, which had alength of 1,058 km. (660 miles), and about six more com- petitors crossed over en route from their incompleted secondcircuit. As distinct from the four previous days, the weather was somewhat unfavourable on June 4, with local fog in JUNE 11, 1925 places. This resulted in causing delay, not so much at thestart, as the weather at Berlin was fairly good, but in the districts around Erfurt and Wiirzburg. Considerable dis-satisfaction was expressed at the action of the German Air Police, who actually prohibited a considerable numberof competitors from starting in the mist, although wireless weather reports had stated that conditions were not sobad elsewhere. The first to arrive home after having com- pleted this circuit was Polte on the Udet U.8 with Bristol"Lucifer" engine, who arrived at 4.09 p.m., having com- pleted the circuit in 10 hrs. 51 mins. He was followed laterby Basser on a Heinkel H.D.21, and the following machines came in later at varying intervals : the Albatros L.68,Udet U.10, Heinkel H.D.32 (Bristol "Lucifer") Junkers T.29, and Heinkel H.D.21.During this circuit two regrettable accidents occurred. One was to the Albatros L.69 piloted by Ungewitter, whichwas completely smashed, although the pilot escaped with a broken leg. It appears that owing to the misty atmosphereUngewitter was flying very low, and when his engine failed he had no opportunity of gliding to a suitable field, but camedown in a garden. The trees broke his fall somewhat, but, nevertheless, the machine was badly damaged, and Unge-witter was taken to hospital in Bamberg. His passenger was uninjured. Spiesz, on a Caspar C.24, had to make aforced landing near Wiirzburg, and damaged his machine badly, although he and his passenger were not injured. Fourth Circuit (June 6-7)Excellent weather prevailed during the completion of the fourth circuit, a distance of 1,070 km. (670 miles). By10 a.m. the following machines had started : Daimler L.20, Daimler L.21, Udet U.10, Albatros L.68, Baumer monoplane,Dietrich monoplane, Heinkel H.D.32, Dietrich monoplane, Baumer biplane, Albatros L.68, Junkers T.29, Dietrichbiplane, Dietrich D.P.2a, Heinkel biplane, Udet " Flamingo," Hemkel H.D.21, Hemkel H.D.21, Junkers T.26, Heinkelbiplane, Dietrich biplane, Udet U.8 (Bristol "Lucifer"), Hemkel H.D.32, Albatros L.68, Caspar " Kobes," JunkersT.29, Heinkel H.D.21, Junkers K.16, Udet "Flamingo," Junkers T.26, Riesler (40 h.p. Anzani), Caspar C.T.I. Some-thing like 35 machines started in this circuit, of which the great majority succeeded in completing the distance of670 miles, while a not inconsiderable number of those that had been unable to complete the third circuit commencedthe fourth at various points along the route. So far the most consistent performances had been put up by Polteon the Udet U.8 with 100 h.p. Bristol " Lucifer " engine, and by Baumer on the Baumer monoplane with 60 h.p.Wright engine. The Baumer monoplane particularly has proved very fast for its low-engined power, a point which,although not counting directly in the competition, is taken into consideration where two machines of the same powerhave completed the same distance. Herr Baumer was again first home on Saturday, June 6. Having left the Berlinaerodrome at 4.30 he returned to his starting point at 12.42, having completed the 670 miles in 8 hrs. 12 mins., whichtime included two compulsory landings and one forced landing en route. Polte's flying time was 10 hrs. 17 mins.,and Basser on a Heinkel H.D.21 with 100 h.p. Mercedes, was third with a time of 10 hrs. 44 mins. Fifth and Last Circuit (June 8-9)The last stage of the Round-Germany competition had been regarded as a fairly easy one in view of the fact thatmost of the country over which this circuit lies is of a com- paratively flat nature and that, consequently, it should bepossible, with safety, to make forced landings almost every- where. The distance is one of 1,034 km. (645 miles). Thirty-eight competitors started from Berlin on this stage. Baumer was again the first man home, returning shortly after oneo'clock, after having completed the circuit in 8 hrs. 8 mins. As before, Polte was second in the Udet U.8 with Bristol" Lucifer," his time being 8 hrs. 48 mins., and Basser was third in his Heinkel H.D.21 with 100 h.p. Mercedes. Bytea-time 11 of the 38 machines had returned to the Temple- hofer Aerodrome, and 24 more by next evening. French Aeroplane Rally ON May 31 a national aeroplane rally, organised by theAero Club of Auvergne, took place at Aulnat aerodrome, the principal event being a competition between aeroplanesflying from various centres to Anlnat. Forty machines, from 15 h.p. to 280 h.p., set out from different towns, andof these 31 landed at Aulnat within the six hours' time limit allowed. Among the competitors was Capt. Pelletier d'Oisy,on a Morane Saulnier (120 Salmson), Fronval, on a similar machine, and Coste, on a Spad Berline (120 Salmson).Fronval, who flew with two passengers 548 miles, was the winner ; Coste second, with five passengers and 555 miles(from Orly), and d'Oisy third, with two passengers and 510 miles (from Villacoublay). Proposed Aerodrome for ColchesterTHE Air Ministry has placed before the Colchester Town Council a proposal for the establishment of a large aerodrome,involving an expenditure of about .£500,000, at Colchester. 360
