FORE:Once, nearly all mechanical knowledge was of the class termed special, and shop manipulations were governed by empirical rules and the arbitrary opinions of the skilled; an apprentice entered a shop to learn a number of mysterious operations, which could not be defined upon principles, and only understood by special practice and experiment. The arrangement and proportions of mechanism were also determined by the opinions of the skilled, and like the manipulation of the shop, were often hid from the apprentice, and what he carried in his memory at the end of an apprenticeship was all that he had gained. The tendency of this was to elevate those who were the fortunate possessors of a strong natural capacity, and to depress the position of those less fortunate in the matter of mechanical "genius," as it was called. The ability to prepare proper designs, and to succeed in original plans, was attributed to a kind of intuitive faculty of the mind; in short, the mechanic arts were fifty years ago surrounded by a superstition of a different nature, but in its influences the same as superstition in other branches of knowledge.

THREE:The cry that rose to her lips was stifled, a firm hand grasped her arm, another was laid tightly over her mouth.I stood near the spot where the ferry-boat used to take people across; but to cross was now out of the question, for any one alighting on the opposite side would be landed in the scorching glare. Therefore, I returned to Lixhe, where I might try to cross the river by the pontoon-bridge, and get to Vis along the other bank of the Meuse.
