To a stranger, however, such an answer as the one I received might have been exceedingly bewildering, and increased his difficulties rather than diminished them. The old law maxim of "_Cujus est solum, ejus est usque ad coelum_," would scarcely apply to real estate in the city of Edinburgh; for houses are not only _rented_ by floors or _flats_, but titles, in fee simple and by deed, are given for floor above floor, oftentimes in the same house; a custom that is difficult to account for, unless from the curious fact that so many of the houses in Edinburgh are built so high, by the sides of hills and precipitous ledges, that an adjoining tenant may oftentimes step from the surface of his cultivated fields into the tenth or twelfth story of his neighbour's back windows, and, by this singular mode of conveyance, able to walk into a comfortable dwelling without the expense of building, and without curtailing the area of his arable ground. By thus getting, for a trifle, the fee simple for the upper story, and of course the privilege of building as many stories on the top of it as he should require, when he could afford the means to do it, his neighbour below was called a "flat." The law, which is generally cruel to most flats, relinquished one of its oldest and most sacred maxims, to support the numerous claims of this kind which the side-hills and ledges in the building-grounds of the city had produced; and so numerous were the _flats_, and so frequent the instances of this new sort of tenure, that the term "flat" has become carelessly and erroneously applied to all the floors or stories of buildings in Edinburgh that are to be let or sold separately from the rest of the house. It was arranged that our stay in Edinburgh was to be but for a few days; and, with this view, we had begun to see its sights pretty rapidly during the two first since our arrival. Many fashionable parties were calling on the Indians in their apartments, and leaving them presents; and at their second night's exhibition the room was crowded to great excess with the fashion and nobility of the city. The Indians discovered at once that they never before were in the midst of audiences so intellectual and genteel. There was nothing of low and vulgar appearance in any part of the room; but all had the stamp of refinement and gentility, which stimulated their pride, and they did their utmost.
