There is no variation in this step; but you can vary the movement by going backwards or forwards at pleasure, instead of continuing the rotatory motion. The Valse
Now, as nothing is really stationary in Leaplow, these two great landmarks are always acting, likewise, on the rotatory principle, changing places periodically; the perpendicular becoming the horizontal, and vice versa; they who toe their respective marks, necessarily taking new views of things as they vary the line of sight.
Nor was this all; he knew that in every wind, however strong it might be, there are periods of calm. If he could start in one of these he would avoid much rotatory motion. The deciding, therefore, of the exact moment for making a fair start was not so easy a matter as one might suppose.
Nor was it till long afterwards that I learned how much the force and direction of the Trade-winds are liable to modification by the particular position which the sun occupies in the heavens; or how far the rotatory motion of the earth, combined with the power which the sun possesses of heating certain portions of the circumambient air, are the regulating causes of the Trades, Monsoons, and, indeed, of all the other winds by which we are driven about.
Hammers, tongs, hoes, axes, adzes, handles to them; needles, bows and arrows, with the mode of feathering the latter; spears, for killing game, with spear-heads having what is termed "dish" on both sides to give them, when thrown, the rotatory motion of rifle-balls; the arts of spinning and weaving, with that of pounding and steeping the inner bark of a tree till it serves as clothing; millstones for grinding corn into meal; the manufacture of the same kind of pots or chatties as in India; the art of cooking, of brewing beer and straining it as was done in ancient Egypt; fish-hooks, fishing and hunting nets, fish-baskets, and weirs, the same as in the Highlands of Scotland; traps for catching animals, etc., etc., have all been so very permanent from age to age, and some of them of identical patterns are so widely spread over the globe, as to render it probable that they were all, at least in some degree, derived from one Source.
But as the star or other celestial object is always apparently moving, in consequence of the real rotatory movement of the earth, the telescope is made to follow it automatically by an ingenious clock-work arrangement. No place, short of the temple of the living God, can be more solemn. The jars of the restless life around it do not disturb the serene intelligence of the half-reasoning apparatus.
When it is out of the circuit, the next second, it is not a magnet, and it lets the clapper go. The clapper, oscillating to and fro, imparts a rotatory motion to a fly-wheel, which transmits it to the drivers on the rails. Such are our motors. They are no novelty, for trial has proved them practicable.
Nature thus set up a double joint for the movements of the head, one between the atlas and axis for rotatory movements, another between the atlas and skull for nodding and side-to-side movements. And all these she increased by giving flexibility to the whole length of the neck. Makers of modern telescopes have imitated the method Nature invented when fixing the human head to the spine.
If we put into the pail grains of any material a little heavier than water, and then give the water a rotatory motion by stirring it, the grains ought, by the centrifugal force imparted to them, to collect around the sides of the pail; but, sinking to the bottom, they do in fact tend to collect at the centre, carried inward by those currents which the friction of the sides and bottom indirectly produces.
Its chief characteristic which is futility, not failure could not be achieved but by the long abuse, the rotatory reproduction, the quotidian disgrace, of the utterances of Art, especially the utterance by words. Gaiety, vigour, vitality, the organic quality, purity, simplicity, precision all these are among the antecedents of trash. It is after them; it is also, alas, because of them.
