Having determined upon the precise site, that which seems most recommended by considerations of healthiness, convenience, &c.; we have next to attend to what appertains exclusively to architectural treatment and character. The general idea of the building, as to its chief masses and parts, extent and arrangement, being sketched out, regard must be had to the greater or less space of the immediate site; to obtaining for it due effect of light and shade, and a background calculated to set it off, upon all which circumstances, it depends nearly as much as a work of sculpture does. In like manner as statues in general have only three sides from which they are calculated to be seen, so also have buildings; nor can I help being of opinion that much harm has been done of late years, both in architecture and sculpture by the attempt at equal display on all sides. The greater part of antique statues were evidently intended to have a wall or background behind them; nor is there, perhaps, any thing more at variance with the effect which statues ought to produce, than the present frequent practice of erecting them in the centre of large squares.
Nearly all productions of architecture, more especially structures adapted for habitation, offer one side stamped as the principal or front, and another, which is its reverse; in which respect they bear a greater analogy to living beings than to plants; the latter having no definite foreside, on the contrary, any part becoming the front, that is towards the spectator. Such being the case, the same rules that are to be observed for displaying a statue, or representation of a living figure to advantage, ought to be attended to in regard to the position of buildings. Agreeing with you that a sheltered situation is the most desirable for your intended villa, I will attempt to explain it upon the theory of the following general principles; namely, upon our beholding any building of the kind, it ought immediately to be evident wherefore it is so placed, and that by being placed precisely where it is, it is part and parcel of its immediate vicinity.
But to confine myself to our particular instance. I think I shall be able to provide an exceedingly agreeable site for your residence, as I learn that a supply of water may be obtained in the grounds, capable of floating superficies of about fifty thousand square feet, and depth in proportion. Accordingly I propose, after the manner shewn in the accompanying ground sketch, (Plate I.) to avail myself of this circumstance, in order to give animation to the now comparatively tame and lifeless character of the place. The reservoir on the upper terrace would keep the basin constantly filled to the level of the lower terrace, before the water escapes into the valley below. By this means, a
