      Of a heavy heart, however, there was not a trace. In the previous chapter I described how beastly they behaved during the destruction of Vis; how the soldiers drank immoderate quantities of alcohol, and then jeered at the wretched refugees; how they indulged in unmitigated vandalism, and wrecked by hand things of which they knew that by and by would be destroyed by fire.Movements and strains may be called two of the leading conditions upon which designs for machines are based: movements determine general dimensions, and strains determine the proportions and sizes of particular parts. Movement and strain together determine the nature and area of bearings or bearing surfaces.

      The functions required in machinery for handling material in a machine shop correspond very nearly to those of the human hands. Nature in this, as in all other things, where a comparison is possible, has exceeded man in adaptation; in fact, we cannot conceive of anything more perfect than the human hands for handling materiala duty that forms a great share of all that we term labour.IV.

      237In the workshop, mechanical knowledge of some kind is continually and often insensibly acquired by a learner, who observes the operations that are going on around him; he is continually availing himself of the experience of those more advanced, and learns by association the rules and customs of the shop, of the business, and of discipline and management. He gathers the technical terms of the fitting-shop, the forge and foundry; notes the operations of planing, turning, drilling, and boring, with the names and application of the machines directed to these operations. He sees the various plans of lifting and moving material, the arrangement and relation of the several departments to facilitate the course of the work in process; he also learns where the product of the works is sold, discusses the merits and adaptation of what is constructed, which leads to considering the wants that create a demand for this product, and the extent and nature of the market in which it is sold.

      And now, looking back at the whole course of early Greek thought, presenting as it does a gradual development and an45 organic unity which prove it to be truly a native growth, a spontaneous product of the Greek mind, let us take one step further and enquire whether before the birth of pure speculation, or parallel with but apart from its rudimentary efforts, there were not certain tendencies displayed in the other great departments of intellectual activity, fixed forms as it were in which the Hellenic genius was compelled to work, which reproduce themselves in philosophy and determine its distinguishing characteristics. Although the materials for a complete Greek ethology are no longer extant, it can be shown that such tendencies did actually exist.

      "It shall be done," he said hoarsely. "Speak."


      "Your face is all cut about," Balmayne growled. "I should think that you will not be able to show up in society for some time to come."
