THREE:It may be urged that beauty, however difficult of attainment or severe in form, is, after all, essentially superficial; and that a morality elaborated on the same principles will be equally superficialwill, in fact, be little more than the art of keeping up appearances, of displaying fine sentiments, of avoiding those actions the consequences of which are immediately felt to be disagreeable, and, above all, of not needlessly wounding anyones sensibilities. Such an imitation of moralitywhich it would be a mistake to call hypocrisyhas no doubt been common enough among all civilised nations; but there is no reason to believe that it was in any way favoured by the circumstances of Greek life. There is even evidence of a contrary tendency, as, indeed, might be expected among a people whose most important states were saved from the corrupt60ing influences of a court. Where the sympathetic admiration of shallow and excitable spectators is the effect chiefly sought after, the showy virtues will be preferred to the solid, and the appearance to the reality of all virtue; while brilliant and popular qualities will be allowed to atone for the most atrocious crimes. But, among the Greeks of the best period, courage and generosity rank distinctly lower than temperance and justice; their poets and moralists alike inculcate the preference of substance to show; and in no single instance, so far as we can judge, did they, as modern nations often do, for the sake of great achievements condone great wrongs. It was said of a Greek and by a Greek that he did not wish to seem but to be just.46 We follow the judgment of the Greeks themselves in preferring Leonidas to Pausanias, Aristeides to Themistocles, and Socrates to Alcibiades. And we need only compare Epameinondas with David or Pericles with Solomon as national heroes, to perceive at once how much nearer the two Greeks come to our own standard of perfection, and how futile are the charges sometimes brought against those from whose traditions we have inherited their august and stainless fame.It would be inferred that the arrangement of these double acting hammers must necessarily be complicated and expensive, but the contrary is the fact. The rams are simply two masses of iron mounted on wheels that run on ways, like a truck, and the impact of the hammers, so far as not absorbed in the work, is [114] neutralised by each other. No shock or jar is communicated to framing or foundations as in the case of single acting hammers that have fixed anvils. The same rule applies in the back stroke of the hammers as the links which move them are connected together at the centre, where the power is applied at right angles to the line of the hammer movement. The links connecting the two hammers constitute, in effect, a toggle joint, the steam piston being attached where they meet in the centre.

ONE:His expression, as Sandy watched narrowly, became one of amusement, he smiled broadly, threw back his head and as he answered Dicks phrase about superstitions and all, he laughed.
ONE:(1.) In comparing steam-hammers with trip or crank hammers what mechanism does steam supplant or represent?(2.) What can be called the chief distinction between steam and other hammers?(3.) Under what circumstances is an automatic valve motion desirable?(4.) Why is a dead or uncushioned blow most effective?(5.) Will a hammer operate with air the same as with steam?
