The windows may have tolerably broad architraves, but no cornices; an ornament both haughty and classical in its effect, and, on both accounts, improper here. They should be in level lines, but grouped at unequal distances, or they will have a formal and artificial air, unsuited to the irregularity and freedom around them. Some few of them may be arched, however, with the curve _a b_, the mingling of the curve and the square being very graceful. There should not be more than two tiers and the garrets, or the building will be too high. So much for the general outline of the villa, in which we are to work by contrast. Let us pass over to that in which we are to work by assimilation, before speaking of the material and color which should be common to both. 246. The grand outline must be designed on exactly the same principles; for the curvilinear proportions, which were opposition before, will now be assimilation. Of course, we do not mean to say that every villa in a hill country should have the form _a b c d_; we should be tired to death if they had: but we bring forward that form as an example of the agreeable result of the principles on which we should always work, but whose result should be the same in no two cases. A modification of that form, however, will frequently be found useful; for, under the depression _h f_, we may have a hall of entrance and of exercise, which is a requisite of extreme importance in hill districts, where it rains three hours out of four all the year round; and under _c d_ we may have the kitchen, servants' rooms, and coachhouse, leaving the large division quiet and comfortable. 247. Then, as in the curved country there is no such distortion as that before noticed, no such evidence of violent agency, we need not be so careful about the appearance of perfect peace; we may be a little more dignified and a little more classical. The windows may be symmetrically arranged; and, if there be a blue and undulating distance, the upper tier may even have cornices; narrower architraves are to be used; the garrets may be taken from the roof, and their inmates may be accommodated in the other side of the house; but we must take care, in doing this, not to become Greek. The material, as we shall see presently, will assist us in keeping unclassical; and not a vestige of column or capital must appear in any part of the edifice. All should be pure, but all should be English; and there should be here, as elsewhere, much of the utilitarian about the whole, suited to the cultivated country in which it is placed.
