SEPTEMBER 16, 1926 ooo ooooo o o o o o [" FLIGHT " photograph. One of the " Eliminated " : The Cranwell C.L.A.4 biplane damaged an un- dercarriage and was refused per- mission to repair. It is therefore out of the com- petition.

Yesterday Bulman consumed 61 lbs. of petrol in carrying a useful load of 430 lbs. over a distance of 312 miles, correspotiding to a mileage of 35-8 miles per gallon, or to 6-S6 ton-miles per gallon. Today he consumed 67-8 lbs. in carrying 430 lbs. a distance of 366 miles, a mileage of 37 -7 miles per gallon, or 7 -24 ton-miles per gallon. Bulman's average during the first two circuits was 128-8 lbs. of petrol for carrying a useful load of 430 lbs. over a distance of 678 miles, this corresponding to an average mileage of 36-9 miles per gallon, or 7-08 ton-miles per gallon In spite of his tank troubles, which must have lost him a not inconsiderable amount of petrol, Hinkler on the Avro " Avis " did not do at all badly. His " figure of merit " for the two circuits was 3-12, and his consumption on the second circuit was 144 lbs., or approximately 20-58 gallons. His mileage during the second circuit was 17-8 miles per gallon,-, or 6-58 ton-miles per gallon, as compared with 18 miles per gallon and 6-66 ton-miles per gallon in the first circuit. It will be seen that, whereas Bulman did rather better on his second circuit than on his first, Hinkler did not do quite so well in the second circuit, the difference no doubt being accounted for bv the leakv tank.
