All private dwellings, however, were built, as in the country, around a square interior garden, and the windows, except those of the front rooms employed for business purposes, looked out upon this. The space occupied, however, was of course much smaller than where ground was less precious, few dwellings having four chambers on the same floor and front. The footway ran on the level of what we call the first story, over a part of the roof of the ground floor; and the business apartments were always the front chambers of the former, while the stores of the merchants were collected in a single warehouse occupying the whole of the ground front. No attempt was made to exhibit them as on Earth. I entered with my host a number of what we should call shops. In every case he named exactly the article he wanted, and it was either produced at once or he was told that it was not to be had there, a thing which, however, seldom happened. The traders are few in number. One or two firms engaged in a single branch of commerce do the whole business of an extensive province. For instance, all the textile fabrics on sale in the province were to be seen in one or other of two warehouses; all metals in sheets, blocks, and wires in another; in a third all finished metal-work, except writing materials; all writing, phonographic, and telegraphic conveniences in a fourth; all furs, feathers, and fabrics made from these in a fifth. The tradesman sells on commission, as we say, receiving the goods from the manufacturer, the farmer, or the State, and paying only for what are sold at the end of each year, reserving to himself one-twenty-fourth of the price. Prices, however, do not vary from year to year, save when, on rare occasions, an adverse season or a special accident affects the supply and consequently the price of any natural product—choice fruit, skins, silver, for instance—obtained only from some peculiarly favoured locality.
