"Ah! The uncle of America! That understands itself! He sent me out a cognac, too! And did he present you to his _dame de compagnie_? She put her head out of a porthole to look at our boat. A Lur, like the others, but with a pair of blistering black eyes! And a jewel in her nose!" "It takes you, Gaston," said Guy Matthews, "to discover a dame of company!" II When the white motor-boat had disappeared in the glitter of the Ab-i-Diz, Senhor Magin, not unlike other fallible human beings when released from the necessity of keeping up a pitch, appeared to lose something of his gracious humor. So, it transpired, did his decorative boatmen, who had not expected to row twenty-five miles upstream at a time when most people in that climate seek the relief of their _serdabs_--which are underground chambers cooled by running water, it may be, and by a tall _badgir_, or air chimney. The running water, to be sure, was here, and had already begun to carry the barge down the Karun. If the high banks of that tawny stream constituted a species of air chimney, however, such air as moved therein was not calculated for relief. But when Brazilians command, even a Lur may obey. These Lurs, at all events, propelled their galley back to the basin of Bund-i-Kir, and on into the Ab-i-Shuteit--which is the westerly of those two halves of the Karun. Before nightfall the barge had reached the point where navigation ends. There Magin sent his majordomo ashore to procure mounts. And at sunset the two of them, followed by a horse boy, rode northward six or seven miles, till the city of Shuster rose dark above them in the summer evening, on its rock that cleaves the Karun in two. The Bazaar by which they entered the town was deserted at that hour, save by dogs that set up a terrific barking at the sight of strangers. Here the _charvadar_ lighted a vast white linen lantern, which he proceeded to carry in front of the two riders. He seemed to know where he was going, for he led the way without a pause through long blank silent streets of indescribable filth and smells. The gloom of them was deepened by jutting balconies, and by innumerable _badgirs_ that cut out a strange black fretwork against amazing stars. At last the three stopped in front of a gate in the vicinity of the citadel. This was not one of the gateways that separate the different quarters of Shuster, but a door in a wall, recessed in a tall arch and ornamented with an extraordinary variety of iron clamps, knobs, locks, and knockers.
