Q. Whether are four-wheeled or six-wheeled engines preferable? A. Much controversial ingenuity has been expended upon the question of the relative merits of the four and six-wheeled engines; one party maintaining that four-wheeled engines are most unsafe, and the other that six-wheeled engines are unmechanical, and are more likely to occasion accidents.
I see that it is a machine in this respect, that it is set going by a force exterior to itself the warmth of the sun acting upon it, and upon the moisture in the soil; but it is unmechanical in that it repairs itself and grows and reproduces itself, and after it has ceased running can never be made to run again.
The moment he appeared at the kitchen door with the candle in his hand, a faint whimpering began in the chimney-corner, and a brown-and-tan-coloured bitch, of that wise-looking breed with short legs and long body, known to an unmechanical generation as turnspits, came creeping along the floor, wagging her tail, and hesitating at every other step, as if her affections were painfully divided between the hamper in the chimney-corner and the master, whom she could not leave without a greeting.
This is the direction in which they have both made their mistake, they treated the unmechanical old Italian work as they would a modern copy of a Cremonese maker, and which had been built upon a machine cut block that served for ever so many warehouse fiddles; these old Italians had to use the hand bow saw, which was not adapted, unless great care was taken, for getting very true upright sides, hence the upper and lower tables are as often as not differing in size, sometimes the upper is largest, at others the lower.
Then follows a little horseplay, and only those who, like myself, regard horses as unmechanical and self-willed instruments of war, know how terrifying a sight and how difficult a task the emboxing of a company's horses can be.
Structure determines function, and function reacts upon structure. This interaction goes on throughout life; cause and effect interchange or play into each other's hands. The more power we spend within limits the more power we have. This is another respect in which life is utterly unmechanical.
McGinnis drifted to this instinctively, as does the born mechanician, to the gist of any problem in mechanics. "Take shame to ye fer this, me man, whoivver ye were," said McGinnis, and the blood shot up under his freckles in indignation. "This is so bad it's not only unmechanical and unprofissional it's absolutely unsportsmanlike!"
It had neither paddle-wheel nor screw; but by some gear not rightly comprehensible to the unmechanical mind, it fetched up over its bow a small bright chain which lay along the bottom of the canal, and paying it out again over the stern, dragged itself forward, link by link, with its whole retinue of loaded skows.
Chemically, the constituents of all of them are undoubtedly the same. It is one of the most curious and suggestive things in living nature. It shows how plastic and versatile life is, and how utterly unmechanical.
Professor Czapek is convinced that "some substances must exist in protoplasm which are directly responsible for the life processes," and yet the chemists cannot isolate and identify those substances. How utterly unmechanical a living body is, at least how far it transcends mere mechanics is shown by what the chemists call "autolysis."
