Most, if not all, of the houses here are of one story--a few, indeed, that stand on the hill-side, have a small room under the elevated side of the main floor. The floors are uniformly, as far as I have seen, made of clay, as also is the roof. They wet it and make it into a kind of mortar, and have a heavy stone roller with which to make it smooth. For the roof, pieces of timber are laid across, mostly a few strong beams, then across them smaller pieces of boards, and flat stones; and on these the earth is laid, in a wet state, and the roller made to pass over it, until with that and their feet they make it hard and smooth. All the roofs are flat, having some little channels to collect the water, and a low place at one side to let it off. There is a way of ascending to the top, which, in large houses, is a fine place for walking and taking the air. These roofs do very well in dry weather, but in the rainy season the water, it is said, comes through, and gives much annoyance to the inmates. The sides are usually made of stone, very coarsely put together; very little mortar is used--often none. They plaster the inside with clay, such as they use for making the floors; and give it a slight coat of whitewash. It is, to be sure, done in poor style; still the houses do pretty well for a summer residence. Generally they have but one room, but occasionally they have two or three. These flat roofs and their earthen materials illustrate what was meant by the grass upon the house-tops--grass does often spring up in the wet season, but the heat of the sun withers it and it comes to nought.
