ONE:A walking excursion of one day took me to201 Brussels. I might have done it in a few hours less, but I lost my way in the wood-paths near Brussels, for at a certain moment I read on a finger-post, "Brussels four miles"; and after walking for a long time, and wondering whether I should ever finish those four miles, I read suddenly: "Brussels��eight miles!" That gave me such a shock that once more I had nearly taken the wrong way.

ONE: ONE:Wind-power, aside from the objections of uncertainty and irregularity, is the cheapest kind of motive-power. Steam machinery, besides costing a large sum as an investment, is continually deteriorating in value, consumes fuel, and requires continual skilled attention. Water-power also requires a large investment, greater in many cases than steam-power, and in many places the plant is in danger of destruction by freshets. Wind-power is less expensive in every way, but is unreliable for constancy except in certain localities, and these, as it happens, are for the most part distant from other elements of manufacturing industry. The operation of wind-wheels is so simple and so generally understood that no reference to mechanism need be made here. The force of the wind, moving in right lines, is easily applied to producing rotary motion, the difference from water-power being mainly in the comparative weakness of wind currents and the greater area required in the vanes upon which the wind acts. Turbine wind-wheels have been constructed on very much the same plan as turbine water-wheels. In speaking of wind-power, the propositions about heat must not be forgotten. It has been explained how heat is almost directly utilised by the steam-engine, and how the effect of heat is utilised by water-wheels in [42] a less direct manner, and the same connection will be found between heat and wind-wheels or wind-power. Currents of air are due to changes of temperature, and the connection between the heat that produces such air currents and their application as power is no more intricate than in the case of water-power.The glowing enthusiasm of Plato is, however, not entirely derived from the poetic traditions of his native city; or perhaps we should rather say that he and the great writers who preceded him drew from a common fount of inspiration. Mr. Emerson, in one of the most penetrating criticisms ever written on our philosopher,129 has pointed out the existence of two distinct elements in the Platonic Dialogues��one dispersive, practical, prosaic; the other mystical, absorbing, centripetal. The American scholar is, however, as we think, quite mistaken when he attributes the second of these tendencies to Asiatic influence. It is extremely doubtful whether Plato ever travelled farther east than Egypt; it is probable that his stay in that country was not of long duration; and it is certain that he did not acquire a single metaphysical idea from its inhabitants. He liked their rigid conservatism; he liked their institution of a dominant priesthood; he liked their system of popular education, and the place which it gave to mathematics made him look with shame on the ��swinish ignorance�� of his own countrymen in that respect;130 but on the whole he classes them among the races exclusively devoted to money-making, and in aptitude for philosophy he places them far below the Greeks. Very different were the impressions brought home from his visits to Sicily and204 Southern Italy. There he became acquainted with modes of thought in which the search after hidden resemblances and analogies was a predominant passion; there the existence of a central unity underlying all phenomena was maintained, as against sense and common opinion, with the intensity of a religious creed; there alone speculation was clothed in poetic language; there first had an attempt been made to carry thought into life by associating it with a reform of manners and beliefs. There, too, the arts of dance and song had assumed a more orderly and solemn aspect; the chorus received its final constitution from a Sicilian master; and the loftiest strains of Greek lyric poetry were composed for recitation in the streets of Sicilian cities or at the courts of Sicilian kings. Then, with the rise of rhetoric, Greek prose was elaborated by Sicilian teachers into a sort of rhythmical composition, combining rich imagery with studied harmonies and contrasts of sense and sound. And as the hold of Asiatic civilisation on eastern Hellas grew weaker, the attention of her foremost spirits was more and more attracted to this new region of wonder and romance. The stream of colonisation set thither in a steady flow; the scenes of mythical adventure were rediscovered in Western waters; and it was imagined that, by grasping the resources of Sicily, an empire extending over the whole Mediterranean might be won. Perhaps, without being too fanciful, we may trace a likeness between the daring schemes of Alcibiades and the more remote but not more visionary kingdom suggested by an analogous inspiration to the idealising soul of Plato. Each had learned to practise, although for far different purposes, the royal art of Socrates��the mastery over men��s minds acquired by a close study of their interests, passions, and beliefs. But the ambition of the one defeated his own aim, to the destruction of his country and of himself; while the other drew into Athenian thought whatever of Western force and fervour was needed for the accomplishment of its205 imperial task. We may say of Plato what he has said of his own Theaet��tus, that ��he moves surely and smoothly and successfully in the path of knowledge and inquiry; always making progress like the noiseless flow of a river of oil��;131 but everywhere beside or beneath that placid lubricating flow we may trace the action of another current, where still sparkles, fresh and clear as at first, the fiery Sicilian wine.
