Basra, if not of Mesopotamia. So sure had the Turks been that they had struck a medal for the occasion, celebrating the triumph of the capture of Basra. Our men found sacks full of these cheap aluminum badges in the Turkish trenches, and they were sold afterwards in the bazaar at Basra by the thousand. But the Turks never wore them, for, at the most extreme and critical moment, across the plain there came a swirling column of dust, a flashing of wheels, and a thundering of hoofs. The sight was too much for the Turks. Another battery, or even a whole brigade of artillery, after those three exhausting days of fighting, was not worth waiting for. So they rose from their trenches and began to flee, and the Arabs, changing their minds with incredible swiftness, fell on them in the rear and cut and slashed them about considerably. In the meanwhile the strange column galloped up. But there were no guns. In place of guns stood a strangely assorted collection of wagons, spring carts, tongas--anything on wheels--that a certain doctor had got together and brought up at full speed to take away the wounded. The Turkish Commander, Suleiman Askari, committed suicide. [Illustration: DONKEY LABOUR IN THE HEAT OF THE DAY.] A New Zealander came into hospital one day from Shaiba way. He was a wireless man, and being so, had found something in the desert that puzzled the science of his mind. He explained the matter. Out there it is a white, undulating expanse, burning hot, but with more air than in Basra. There are extraordinary effects of perspective. A man standing a short way off may assume gigantic proportions, or look like a dwarf. A motor car near by would seem to lose its solidity and dissolve into a few filmy lines. The mirage of water is everywhere. An Arab might lie in the open and no one would see him. A post might look like a horseman at full gallop. It was a country of topsy-turveydom as regards the subjective estimate of the eyes. But what puzzled the wireless man was this. He thought he understood how eye-strain and difference of refractive power of the layers of heated air, or reflected light from the ground and such physical considerations could cause these illusions. But what he could not understand was how it came about that several men would experience exactly the same illusion. Why should a post simultaneously appear as an Arab on horseback or an Arab crawling stealthily on the ground to half a dozen men? Mirage, like Rumour, is a curious thing. It may have some inner connection with the set of a man's feelings. It has its pleasant side when it paints water and palms where there is no water nor any palms. It has its sinister side when it clothes the most innocent features of the landscape in images of dread. Who knows how it touched up that flying column of ambulance wagons in the eyes of the Turks? There are certain areas that are constantly the site of mirage. Our gunners found this a continual difficulty at the
