The private houses in Tlamco were of sun-dried bricks, covered with stucco, elaborately ornamented and delicately tinted. They were seldom more than one story high, with ceilings of ornamental woods, while the walls were tinted or hung with simple cotton tapestries. The flat-roofs were often bright with potted plants, and these dwellings were invariably surrounded by flowers and a stretch of greensward. The hospitals, the barracks, the Brotherhood houses and those occupied by the priestesses faced the cardinal points and were the squares within the circular streets. They were uniformly four stories high, with truncated sloping roofs, and terraced grounds, forming ornamental bits of landscape among the trees, and commanding a fine view of bay and harbor. Clusters of sunflowers grew here and there in out-of-the-way places. Free use was made of cherry, laurel, clove and lavender plants along the highways, because they were known to produce ozone; and the gardens contained their favorite flowers—narcissus, hyacinth and mignonette in abundance. Orondo was giving an audience to the mathematicians who were employed in the Hall of Quippos, at Iaqua, where the government accounts were kept. And when it was known that Alcamayn had arrived Orondo sent and begged his presence. When the jeweler stepped into the hall, he found the place littered with quippos of all kinds. They were scattered about on chairs, on the tables, and some were hanging upon the walls, while clerks called the numbers and tallied the curiously knotted cords in a monotonous drone. There were intricate estimates for the warriors shown by the red cords and fringes; yellow denoted the gold used in the mechanical arts and industries and in the temples; but these were few and simple in combination compared with the white ones, indicating the enormous amount of civil transactions for the current month. Silver was used for state accounts, and its knots were curious little buttons, full of meaning for the men who mastered the art of the quippos. The largest bundle of all was the green, which, by its varying shades and fanciful combinations recorded the amount of wheat, corn and all agricultural produce owned or used by the pueblo city of Tlamco. “One knot! Red signal corps,” called the teller. “Signal corps, ten,” answered the tally. “Two single knots, and one knot doubly intertwined, silver, Alcamayn.” “Two knots, twenty; one doubly intertwined, one hundred,” repeated the tally. “One knot, triply intertwined, yellow, Alcamayn.” “Hold!” cried Orondo. “Alcamayn, hast thou made requisition for a thousand grains of gold? Thy parchment is not properly stamped, and we cannot give thee so much treasure on irregular demand.” “Wilt thou grant me to see it?” said Alcamayn, reaching out for the document. “I must have both gold and silver quickly. There will scarce be time enough to prepare the gifts needed because of thy going to the Monbas.”
