All the partition-walls, dividing off the several apartments, are necessarily of masonry; both because the pressure from above is enormous; and, that wood cannot be trusted, where the white-ants could honeycomb its interior, without being much, if at all, noticed on its surface. These partition-walls are carried up about six inches above the tarras roof; whereby the latter appears to be divided into chequers, corresponding with the several apartments. Small channels are cut, to allow the water to pass into the spouts, or drains; from which jars, of about a hogshead in measurement, are filled with water intended for table use. Some spouts are made to extend full a yard from the wall, and, in some instances, have canvas hoses attached, for the purpose of leading the water into the jars; but the more modern practice is to build pipes of pottery within the wall, or to clamp them to it with iron, until their lower ends, which are crooked for the purpose, form a proper debouchure. The latter mode, however, in very heavy rains, subjects the walls to be damped, in consequence of the fall of water being greater than the pipes can instantly carry off. This may give some idea of those deluges which at times take place, almost instantaneously.
The tops of houses are invariably enclosed with breast-parapets, or with balustrades; which give a very finished appearance to these superb buildings. With the exception of those ridges formed by the continuation of the partition-walls, the roofs afford a pleasant promenade at certain seasons: some of them command most interesting views. During the very hot weather, probably from the end of April to the setting in of the rains in the first or second week of June, many gentlemen have their cots, (as the bed, with all its apparatus, is usually called,) carried to the tops of their houses, and sleep there during the night. This may appear a very hazardous proceeding; but, when it is considered, that no dew, worthy of notice, falls at that season, and, that the cots have generally curtains, which would receive, and absorb, what little might fall, we may, on the whole, pronounce it to be less dangerous than should at first be supposed. If, indeed, this were to be done more to the southward, near the mouth of the Hoogly river, where the immense marshes, the ouze left by the returning tides, and the jungles, which every where abound, produce the most deleterious exhalations, we should then be correct in exclaiming against the practice: but few, very few, instances could be adduced of any serious indisposition having attended it; while, on the other hand, it is confessed by all who have adopted it, that the greatest refreshment ever resulted; enabling them to rise early, divested of that most distressing lassitude attendant upon sleeping in an apartment absolutely communicating a febrile sensation, and peculiarly oppressive to the lungs.
