"Don't know 'im. Prince 'oo?" "Aladdin." "What--the pantomime feller? Lor', you must be gettin' on in years! Well, now, did this chap give yer a reference?" The spirit looked puzzled, and Alf decided that in Aladdin's time servants could not have had characters. He continued his catechism. "An' what's yer name, mate?" "Abdulkindeelilajeeb was I aforetime, O Master, but now I am called Abdulzirrilajeeb." "Gorblimey," said Alf blankly. "You don't expect me to do that when I speaks to yer, I 'ope!" Then after a pause he added, "I shall call yer Eustace." The djinn looked pleased. "In truth, O possessor of wisdom, it is a lordly name." "'Tis well," replied the possessor of wisdom with a melodramatic wave of the hand. "Now, tell me. Yer always poppin' up an' askin' for orders--what is it you want to do? What's yer partickler line?" "My Lord hath but to command," said the newly-christened Eustace with superb simplicity. "Garn, what a whopper!" Alf snorted incredulously. He had an ingrained dislike of "swank" in any form; and he looked about him at once, seeking some impossible task with which he might upset this complacent creature's vanity. His imagination failed utterly to respond to the sudden strain placed upon it. His eye wandered round the unedifying landscape and found no source of inspiration. In despair he glanced up at the skies, and there he found the idea he sought. High in the air above the British lines--so high that they were only just visible--were two aeroplanes. That they were Boche and Briton, engaged in a duel, was plain; but which was which it was impossible to make out. No doubt an expert would have known at once by a dozen signs; but Alf's data for distinguishing friend from foe in the air began and ended with the official markings--the tricolor rings of the Allies or the German black cross painted on the wings of the machines. When these signs were not visible he worked, as did most of his mates, on the rough principle that if an aeroplane dropped bombs on you it was certainly a Boche, while if it refrained it was probably British. He directed the djinn's attention aloft. "Now then," he said in triumphant tones. "See them two airyplanes up there? Well, if yer so bloomin' clever, 'op up and bring down the Boche one to me 'ere." Eustace disappeared immediately, and Alf, incredulous though he was that anything out of the ordinary was going to happen, gazed up at the two tiny machines, still diving and circling in their attempts to out-maneuver one another. The duel was, however, nearing an end. As Alf gazed, one of the two suddenly turned tail and fled. The other gave chase, and seemed on the very point of victory, when suddenly the pursuing plane seemed to check in mid-air and began to descend.
