THE FOUR COURSES : The final course has to be flown twice, and Hatfield is the turn ing point the first time around. BELOW : The location of the four courses. The distances are: First, 223.8 miles.

Fourth (twice), 205.6 miles. selves are not very useful to our readers for forming an opinion of the sort of speeds the machines will have to do in order to stand a chance in the race, we have taken the liberty of making the best guess we could. Taking the limit machines at 110 m.p.h., which is the lowest speed at which machines are handicapped in the race, it was found that this made the scratch machine do about 172 m.p.h. As the Coupe Deutsch Comper " Swift " is reputed to be capable of about 178-180 m.p.h., and an allowance should be made for time spent in taking off and lost in rounding the corners of the different rounds, this appears fairly reasonable, and the speeds which we have worked out are based on 110 m.p.h. for the limit man and 172 m.p.h. for the scratch man. Actually, it is quite likely that the handi- cappers have calculated their figures on 112 m.p.h. for the limit machine, which would make the scratch machine about 176^ m.p.h. Thus it will be seen that if we have not " guessed " quite right, and the speeds actually used as a basis by the handicappers are slightly different, the speed column of our table should still be useful in giving a good indication of the relative speeds which the different machines should do.

Enclosures have been erected from which the start and finish of the racing aeroplanes can be seen. Tickets are Is. 6d., 2s. 6d. and 5s., while the charges for vehicles are: Motor cars 2s. 6d., motor cycles and sidecars Is. 6d. and motor cycles solo 6d. The car parks have been so arranged that motor cars can be parked right up to the rails, so that, should the weather be unkind, spectators will be able to watch the flying from the comfort of their cars. For those who prefer to be in the open there are large supplies of chairs. The race for the King's Cup has been so arranged this year that it virtually consists of a series of short races. It may even be that the start of one heat will take place before the finish of the previous heat, so that there should be something to watch all day. If, however, any gaps should occur, preparations have been made for certain interesting events to be flown, so that literally there should be few moments during the day when there is not at least one aeroplane in the sky. The race will be flown in a number of heats, and over four separate courses. The start and finish of all are at Hatfield, and the first course is to Felixstowe and Bircham Newton. The distances are: Hatfield-Felixstowe, 67.9 miles ; Felixstowe-Bircham Newton, 70.3 miles ; Bircham Newton-Hatfield, 85.6 miles ; total, 223.8 miles. At 110 m.p.h. an aeroplane will cover this distance in a couple of minutes over 2 hr. At 180 m.p.h. a machine would take about 1£ hr. to cover the course. Felixstowe and 660
