ONE:"Nothing! But, madame, I want to pay for what I drink!"Designing, or generating the plans of machinery, may be considered the leading element in engineering manufactures or machine construction, that one to which all others are subordinate, [75] both in order and importance, and is that branch to which engineering knowledge is especially directed. Designing should consist, first, in assuming certain results, and, secondly, in conceiving of mechanical agents to produce these results. It comprehends the geometry of movements, the disposition and arrangement of material, the endurance of wearing surfaces, adjustments, symmetry; in short, all the conditions of machine operation and machine construction. This subject will be again treated of at more length in another section.
THREE:If the Roman conquest did not altogether put an end to these sentiments, it considerably mitigated their intensity. The imperial city was too strong to feel endangered by the introduction of alien deities within its precincts. The subject states were relieved from anxiety with regard to a political independence which they had irrecoverably lost. Moreover, since the conquests of Alexander, vast aggregations of human beings had come into existence, to which the ancient exclusiveness was unknown, because they never had been cities at all in the ancient sense of the word. Such were Alexandria and Antioch, and these speedily became centres of religious syncretism. Rome herself, in becoming the capital of an immense empire, acquired the same cosmopolitan character. Her population consisted for the most part of emancipated slaves, and of adventurers from all parts of the world, many of whom had brought their national faiths with them, while all were ready to embrace any new faith which had superior attractions to offer. Another important agent in the diffusion and propagation of new religions was the army. The legions constituted a sort of migratory city, recruited from all parts of the empire, and moving over its whole extent. The dangers of a military life combined with its authoritative ideas are highly favourable to devotion; and the soldiers could readily adopt new modes for the expression of this feeling both from each other and from the inhabitants of the countries where they were stationed, and would in turn204 become missionaries for their dissemination over the most distant regions. That such was actually the case is proved by numerous religious inscriptions found in the neighbourhood of Roman camps.313
THREE:Marine and railway engineering have engrossed the best talent in the world; investigation and research has been expended upon these subjects in a degree commensurate with their importance, and it would be hard to suggest a single want in the many able text-books that have been prepared upon the subjects. Marine and railway engineering are sciences that may, in a sense, be separated from the ordinary constructive arts, and studied at the end of a course in mechanical engineering, but are hardly [61] proper subjects for an apprentice to take up at the beginning."Why should I deny it?" Leona said boldly. "My husband was murdered. He was slain by Dr. Gordon Bruce for the sake of his money."
