The fighting on the other aide, which now ensues as

a regular result of the air raids on England, is a most interesting development. More German machines aro driven down there than on this aide, and the reason is very simple. The raiders climb to an enormous height on leaving their aerodromes, and it is an extremely difficult matter for our defenders to climb high enough when warning has been given here. The process of climbingabove ten thousand feet, where the rarefied air gives little support, is a most slow and laborious busioesa,and it is possible at allonly to theanoat powerfulmachines. The Dunkirk airmen, however, have enough time to climb to the necessary height and be ready to waylay the raiderson their return. To counteract this move the Germans send out supports for the raiders, and it seems likely that the Dunkirk battles, both in number of machines engaged and in the results, will vastly exceed in im- portance the operations on this side. We must make up our minds tient the bast chance of bringing down raiders is not here, but towards the end of their return journey.
