We may here, therefore, close our inquiries into the subject of construction; nor must the reader be dissatisfied with the simplicity or apparent barrenness of their present results. He will find, when he begins to apply them, that they are of more value than they now seem; but I have studiously avoided letting myself be drawn into any intricate question, because I wished to ask from the reader only so much attention as it seemed that even the most indifferent would not be unwilling to pay to a subject which is hourly becoming of greater practical interest. Evidently it would have been altogether beside the purpose of this essay to have entered deeply into the abstract science, or closely into the mechanical detail, of construction: both have been illustrated by writers far more capable of doing so than I, and may be studied at the reader's discretion; all that has been here endeavored was the leading him to appeal to something like definite principle, and refer to the easily intelligible laws of convenience and necessity, whenever he found his judgment likely to be overborne by authority on the one hand, or dazzled by novelty on the other. If he has time to do more, and to follow out in all their brilliancy the mechanical inventions of the great engineers and architects of the day, I, in some sort, envy him, but must part company with him: for my way lies not along the viaduct, but down the quiet valley which its arches cross, nor through the tunnel, but up the hill-side which its cavern darkens, to see what gifts Nature will give us, and with what imagery she will fill our thoughts, that the stones we have ranged in rude order may now be touched with life; nor lose for ever, in their hewn nakedness, the voices they had of old, when the valley streamlet eddied round them in palpitating light, and the winds of the hill-side shook over them the shadows of the fern.
[60] I have spent much of my life among the Alps; but I never pass, without some feeling of new surprise, the Chalet, standing on its four pegs (each topped with a flat stone), balanced in the fury of Alpine winds. It is not, perhaps, generally known that the chief use of the arrangement is not so much to raise the building above the snow, as to get a draught of wind beneath it, which may prevent the drift from rising against its sides.
