      "Here's a discovery," he said, excitedly. "Here's a perfect revelation. Mr. Charlton, will you trust me for four and twenty hours with this letter? I've found out something that fairly takes my breath away."


      The safety, simplicity, and reliable action of hydraulic machinery has already led to its extensive employment for moving and lifting weights, and it is fair to assume that the importance and success of this invention fully entitle it to be classed as one of the most important that has been made in mechanical engineering during fifty years past. The application of hydraulic force in operating the machinery used in the processes for steel Bessemer manufacture, is one of the best examples to illustrate the advantages and principles of the hydraulic system. Published drawings and descriptions of Bessemer steel plant explain this hydraulic machinery."Please be good enough to have a look at my papers, and then...."


      "Are you quite sure," he asked, "that Mamie is her own child?"

      The spectators gave themselves up wholly to the fun. It must have seemed to them that this extraordinary cricketer was also gifted with a sense of humour, however eccentric; and that his nonsensical action was intended by way of retaliation for the ironic cheers that had greeted his running at all. Nobody, except Arthur Withers, realised that the Clockwork man run thus far because for some reason he had been unable to stop himself. It may be remarked here that many of the Clockwork man's subsequent performances had this same accidental air of humour; and that even his most grotesque attitudes gave the observer an impression of some wild practical joke. He was so far human, in appearance and[Pg 35] manner, in spite of those peculiar internal arrangements, which will be dealt with later, that his actions produced an instantaneous appeal to the comic instinct; and in laughing at him people forgot to take him seriously.


      Ordinary machinery, on the reverse, is stationary, generally consumes a regular amount of power, is not subjected to such uncertain strains, and as a rule acts without its operation being controlled by the will of attendants."But are you sure? Where are the French now, and where did the British land?"

      If asked for advice as to the most important object for an apprentice to aim at in beginning his fitting course, nine out of ten experienced men will say, "to do work well." As power is measured by force and velocity, work is measured by the two conditions of skill and time. The first consideration being, how well a thing may be done, and secondly, in how short a time may it be performed; the skill spent on a piece of work is the measure of its worth; if work is badly executed, it makes no difference how short the time of performance has been; this can add nothing to the value of what is done although the expense is diminished.The cause which first arrested and finally destroyed the free movement of Greek thought was not any intrinsic limitation or corruption of the Greek genius, but the ever-increasing preponderance of two interests, both tending, although in different ways and different degrees, to strengthen the principle of authority and to enfeeble the principle of reason. One was the theological interest, the other was the scholastic interest. The former was the more conspicuous and the more mischievous of the two. From the persecution of Anaxagoras to the prohibition of philosophical teaching by Justinian, we may trace the rise and spread of a reaction towards superstition, sometimes advancing and sometimes receding, but, on the whole, gaining ground from age to age, until from the noontide splendour of Pericles we pass to that long night which stretches in almost impenetrable darkness down to the red and stormy daybreak of the Crusades. And it was a reaction which extended through all classes, including the philosophers themselves. It seems to me that where the Athenian school, from Socrates on, fall short of their predecessors, as in some points they unquestionably do, their inferiority is largely due to this cause. Its influence is very perceptible in weakening the speculative energies of thosexii who stand at the greatest distance from the popular beliefs. It was because dislike for theology occupied so large a place in the thoughts of Epicurus and his disciples, that they valued science only as a refutation of its teaching, instead of regarding it simply as an obstacle to be removed from the path of enquiry. More than this; they became infected with the spirit of that against which they fought, and their absolute indifference to truth was the shadow which it cast on their minds.
