““The first and last lesson of the useful arts is that Nature tyrannizes over our works. They must be conformed to her law, or they will be ground to powder by her omnipresent activity. Nothing droll, nothing whimsical will endure. Nature is ever interfering with Art. You cannot build your house or pagoda as you will, but as you must. There is a quick bound set to your captice. The leaning tower can only lean so far. The verandah or pagoda roof can curve upward only to a certain point. The slope of your roof is determined by the weight of snow. It is only within narrow limits that the discretion of the architect may range: gravity, wind, sun, rain, the size of men and animals, and such like, have more to say than he. It is the law of fluids that prescribes the shape of the boat, — keel, rudder, and bows, — and, in the finer fluid above, the form and tackle of the sails. Man seems to have no option about his tools, but merely the necessity to learn from Nature what will fit best, as if he were fitting a screw or a door.””
