For a half century past no considerable change has been made in engine lathes, at least no new principle of operation has been added, but many improvements have been made in their adaptation and capacity for special kinds of work. Improvements have been made in the facilities for changing wheels in screw cutting and feeding, by frictional starting gear for the carriages, an independent feed movement for turning, arrangements to adjust tools, cross feeding and so on, adding something, no doubt, to the efficiency of lathes; but the improvements named have been mainly directed to supplanting the skill of lathemen.

Throwing it open, he faced Jeff.A FEW words by way of introduction.Sandy had lost his suspicious look. His interest, as much as that of his older chums, was caught and chained by the coming possibilities and he put down the letter to listen to Jeff.
ONE:An additional influence, not the less potent because unacknowledged, was the same craving for a principle of unity that had impelled early Greek thought to seek for the sole substance or cause of physical phenomena in some single material element, whether water, air, or fire; and just as these various principles were finally decomposed into the multitudinous atoms of Leucippus, so also, but much more speedily, did the general principle of knowledge tend to decompose itself into innumerable cognitions of the partial ends or utilities which action was directed to achieve. The need of a comprehensive generalisation again made itself felt, and all good was summed up under the head of happiness. The same difficulties recurred under another form. To define happiness proved not less difficult than to define use or practical knowledge. Three points of view offered themselves, and all three had been more or less anticipated by Socrates. Happiness might mean unmixed pleasure, or the exclusive cultivation of mans higher nature, or voluntary subordination to a larger whole. The founder of Athenian philosophy used to present each of these, in turn, as an end, without recognising the possibility of a conflict between134 them; and it certainly would be a mistake to represent them as constantly opposed. Yet a truly scientific principle must either prove their identity, or make its choice among them, or discover something better. Plato seems to have taken up the three methods, one after the other, without coming to any very satisfactory conclusion. Aristotle identified the first two, but failed, or rather did not attempt to harmonise them with the third. Succeeding schools tried various combinations, laying more or less stress on different principles at different periods, till the will of an omnipotent Creator was substituted for every human standard. With the decline of dogmatic theology we have seen them all come to life again, and the old battle is still being fought out under our eyes. Speaking broadly, it may be said that the method which we have placed first on the list is more particularly represented in England, the second in France, and the last in Germany. Yet they refuse to be separated by any rigid line of demarcation, and each tends either to combine with or to pass into one or both of the rival theories. Modern utilitarianism, as constituted by John Stuart Mill, although avowedly based on the paramount value of pleasure, in admitting qualitative differences among enjoyments, and in subordinating individual to social good, introduces principles of action which are not, properly speaking, hedonistic. Neither is the idea of the whole by any means free from ambiguity. We have party, church, nation, order, progress, race, humanity, and the sum total of sensitive beings, all putting in their claims to figure as that entity. Where the pursuit of any single end gives rise to conflicting pretensions, a wise man will check them by reference to the other accredited standards, and will cherish a not unreasonable expectation that the evolution of life is tending to bring them all into ultimate agreement.
This analogy with subsequent developments is aided, so far as it goes, by the admixture of a certain Platonic element with Virgils Stoicism, shown chiefly by the references to an antenatal existence of the soul, introduced for the purpose of bringing Romes future heroes on the scene. This, however, is the last example of an attempt on the part of a Roman writer to combine Platos teaching with Stoicism.286 At a time when the Romans were more conscious of their literary dependence on Greece than was the case after the Augustan age had reached its zenith, they were probably drawn by the beauty of its literary form to study a system which could otherwise interest them but little. Thus, not only is Cicero full of admiration for Platoas, indeed, might be expected with so highly cultivated a disciple of the Academybut Cato, according to the well-known story, spent his last hours reading and re-reading the Phaedo; and his nephew Brutus also occupied an intermediate position between the Old Academy and the Porch. The Roman love of simplification and archaism induced subsequent thinkers either to let Platonism drop altogether, or to study those elements in which it differed from the pure naturalistic doctrine under their Pythagorean form. It may even be doubted whether Virgils psychology is not derived from Pythagoras rather than from Plato; Ovid, so far as he philosophises at all, is unquestionably a follower of the former;287 and in the moral teaching of the Sextii, who flourished under Augustus, Pythagorean principles are blended with Stoicism.288 It is another manifestation of the same effort to grasp every Greek doctrine by its roots, that Horace should proclaim himself the disciple of Aristippus rather than of Epicurus.289 Even he, however, feels183 himself drawn with advancing years towards the nobler faith which was now carrying all before it.290Outside was the clatter of hoofs and the jingle of harness. The hall door stood open; Balmayne politely helped Maitrank on with his heavy coat. Hetty, standing in the background, began to wonder if she was dreaming.
