TWO:Xenophon gives the same interest a more edifying direction when he enlivens the dry details of his Cyropaedia with touching episodes of conjugal affection, or presents lessons in domestic economy under the form of conversations between a newly-married couple.107 Plato in some respects transcends, in others falls short of his less gifted contemporary. For his doctrine of love as an educating process��a true doctrine, all sneers and perversions notwithstanding��though readily applicable to the relation of the sexes, is not applied to it by him; and his project of a common training for men and women, though suggestive of a great advance on the existing system if rightly carried out, was, from his point of view, a retrograde step towards savage or even animal life, an attempt to throw half the burdens incident to a military organisation of society on those who had become absolutely incapable of bearing them.

TWO:This brings us back to the old proposition, that for structures which do not involve motion, mathematical data will furnish dimensions; but the same rule will not apply in machinery. To follow the proportions for shafts that would be furnished by pure mathematical data would in nearly all cases lead to error. Experience has demonstrated that for ordinary cases, where power is transmitted and applied with tolerable regularity, a shaft three inches in diameter, making one hundred and fifty revolutions a minute, its bearings three to four diameters in length, and placed ten feet apart, will safely transmit fifty horse-power.The art of keeping reasonably clean even in a machine shop is worth studying; some men are greased from head to foot in a few hours, no matter what their work may be; while others will perform almost any kind of work, and keep clean without sacrificing convenience in the least. This difference is the result of habits readily acquired and easily retained.

TWO:The lifting strain at the front end of a platen is of course increased as the height at which the cutting is done above its top, but this has not in practice been found a difficulty of any importance, and has not even required extra length or weight of platens beyond what is demanded to receive pieces to be planed and to resist flexion in fastening heavy work. The reversing movement of planing machine platens already alluded to is one of the most complex problems in machine tool movement.

TWO:"There was nothing else for it," she said. "I wish I had killed him, then I should have got the notes and returned home comfortably. As it is half the officers in London are looking for the car at the present moment. See that!"250

TWO:��We��re off!�� exulted Dick.

TWO:Before the ideas which we have passed in review could go forth on their world-conquering mission, it was necessary, not only that Socrates should die, but that his philosophy should die also, by being absorbed into the more splendid generalisations of Plato��s system. That system has, for some time past, been made an object of close study in our most famous seats of learning, and a certain acquaintance with it has almost become part of a liberal education in England. No170 better source of inspiration, combined with discipline, could be found; but we shall understand and appreciate Plato still better by first extricating the nucleus round which his speculations have gathered in successive deposits, and this we can only do with the help of Xenophon, whose little work also well deserves attention for the sake of its own chaste and candid beauty. The relation in which it stands to the Platonic writings may be symbolised by an example familiar to the experience of every traveller. As sometimes, in visiting a Gothic cathedral, we are led through the wonders of the more modern edifice��under soaring arches, over tesselated pavements, and between long rows of clustered columns, past frescoed walls, storied windows, carven pulpits, and sepulchral monuments, with their endless wealth of mythologic imagery��down into the oldest portion of any, the bare stern crypt, severe with the simplicity of early art, resting on pillars taken from an ancient temple, and enclosing the tomb of some martyred saint, to whose glorified spirit an office of perpetual intercession before the mercy-seat is assigned, and in whose honour all that external magnificence has been piled up; so also we pass through the manifold and marvellous constructions of Plato��s imagination to that austere memorial where Xenophon has enshrined with pious care, under the great primary divisions of old Hellenic virtue, an authentic reliquary of one standing foremost among those who, having worked out their own deliverance from the powers of error and evil, would not be saved alone, but published the secret of redemption though death were the penalty of its disclosure; and who, by their transmitted influence, even more than by their eternal example, are still contributing to the progressive development of all that is most rational, most consistent, most social, and therefore most truly human in ourselves.
