81. It is utterly impossible to give rules for the attainment of these effects, since they are the result of a feeling of the proportion and relation of lines, which, if not natural to a person, cannot be acquired, but by long practice and close observation; and it presupposes a power rarely bestowed on an English architect, of setting regularity at defiance, and sometimes comfort out of the question. We could give some particular examples of this grouping; but, as this paper has already swelled to an unusual length, we shall defer them until we come to the consideration of street effects in general. Of the chimney in the abstract, we are afraid we have only said enough to illustrate, without removing, the difficulty of designing it; but we cannot but think that the general principles which have been deduced, if carefully followed out, would be found useful, if not for the attainment of excellence, at least for the prevention of barbarism. OXFORD, _Feb. 10, [1838]._ VI. THE COTTAGE--CONCLUDING REMARKS. "Nunquam aliud Natura, aliud Sapientia, dicit." _Juvenal_ xiv. 321. 82. It now only remains for us to conclude the subject of the cottage, by a few general remarks on the just application of modern buildings to adorn or vivify natural scenery. There are, we think, only three cases in which the cottage is considered as an element of architectural, or any other kind of beauty, since it is ordinarily raised by the peasant where he likes, and how he likes; and, therefore, as we have seen, frequently in good taste. 83. I. When a nobleman, or man of fortune, amuses himself with superintending the erection of the domiciles of his domestics. II. When ornamental summer-houses, or mimicries of wigwams, are to be erected as ornamental adjuncts to a prospect which the owner has done all he can to spoil, that it may be worthy of the honor of having him to look at it. III. When the landlord exercises a certain degree of influence over the cottages of his tenants, or the improvements of the neighboring village, so as to induce such a tone of feeling in the new erections as he may think suitable to the situation. 84. In the first of these cases, there is little to be said; for the habitation of the domestic is generally a dependent feature of his master's, and, therefore, to be considered as a part of it. Porters' lodges are also dependent upon, and to be regulated by, the style of the architecture to which they are attached; and they are generally well managed in England, properly united with the gate, and adding to the effect of the entrance. In the second case, as the act is in itself a barbarism, it would be useless to consider what would be the best mode of perpetrating it. In the third case, we think it will be useful to apply a few general principles, deduced from positions formerly advanced.
