FORE:A principle in mechanics may be known, and even familiar to a learner, without being logically understood; it might even be said that both theory and practice may be learned without the power to connect and apply the two things. A person may, for example, understand the geometry of tooth gearing and how to lay out teeth of the proper form for various kinds of wheels, how to proportion and arrange the spokes, rims, hubs, and so on; he may also understand the practical application of wheels as a means of varying or transmitting motion, but between this knowledge and a complete wheel lies a long train of intricate processes, such as pattern-making, moulding, casting, boring, and fitting. Farther on comes other conditions connected with the operation of wheels, such as adaptation, wear, noise, accidental strains, with many other things equally as important, as epicycloidal curves or other geometrical problems relating to wheels.The excellent man went on weeping, and I was not able to console him and did not know what to say. He took my arm, and led me to the large common hall, where twenty wounded Germans lay, who had been hit in the fight for the forts. He went to one bed after the other, and, with tears in his eyes, asked each man how he felt, and inquired, "Are you ... properly ... cared for ... here? Are you?" The sick men turned round, their eyes beamed, and they stammered words full of gratitude. Others said nothing, but took the Head's hand and pressed it long and warmly.
