      Dear Daddy-Long-Legs,

      The arrangement of patterns with reference to having certain parts of castings solid and clean is an important matter, yet one that is comparatively easy to understand. Supposing the iron in a mould to be in a melted state, and to contain, as it always must, loose sand and 'scruff,' and that the weight of the dirt is to melted iron as the weight of cork is to water, it is easy to see where this dirt would lodge, and where it would be found in the castings. The top of a mould or cope, as it is called, contains the dirt, while the bottom or drag side is generally clean and sound: the rule is to arrange patterns so that the surfaces to be finished will come on the bottom or drag side.theirs in the bath tub and carried yours in the class procession.

      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.

      The principal improvements and changes in machine fitting at the present time is in the application of special tools. A lathe, a planing machine, or drilling machine as a standard machine, must be adapted to a certain range of work, but it is evident that if such tools were specially arranged for either the largest or the smallest pieces that come within their capacity, more work could be performed in a given time and consequently at less expense. It is also evident that machine tools must be kept constantly at work in order to be profitable, and when there are not sufficient pieces of one kind to occupy a machine, it must be employed on various kinds of work; but whenever there are sufficient pieces of the same size upon which certain processes of a uniform character are to be performed, there is a gain by having machines constructed to conform as nearly as possible to the requirements of special work, and without reference to any other.


      The post-chaise was a tonga, escorted by a mounted sowar, armed with a naked sword. He rode ahead at a rattling trot, but the clatter was drowned by the shouts of the driver and of the sais, who scrambled up on the steps and urged the steeds on with excited flogging.In connection with the summons, which had been sent in the name of the archdiocese to De Tijd, and had been proclaimed in all the churches of Antwerp in the morning, his Eminence insisted that it should be printed in its entirety, as very many priests had taken refuge in The Netherlands, whose help was pressingly wanted in the arch-diocese in many of the parishes.


      I couldn't say more, my voice stuck in my throat.370


      A pendulum vibrating in uniform time regardless of distance, but always as its length, if arranged to perform one vibration in a given time, gave a constant measure of length. Thus lineal measure comes from time; cubic or solid measures from lineal measure, and standards of weight from the same source; because when a certain quantity of a substance of any kind could be determined by lineal measurement, and this quantity was weighed, a standard of weight would be reached, provided there was some substance sufficiently uniform, to which reference could be made in different countries. Such a substance is sea or pure water; weighed in vacuo, or with the air at an assumed density, water gives a result constant enough for a standard of [147] weight.As a rule, ornament should never be carried further than graceful proportions; the arrangement of framing should follow as nearly as possible the lines of strain. Extraneous decoration, such as detached filagree work of iron, or painting in colours, is [159] so repulsive to the taste of the true engineer and mechanic that it is unnecessary to speak against it.
