FORE:When we were stopped by German outposts he put out of the window a paper at which they just glanced, stood to attention, and said that all was well. They did not even want to see my papers. In a casual way I asked what a miraculous sort of paper he had, and then he pretended that, by the help of those officers who were quartered on him, he had got a certificate from the Governor of Lige with the order to treat him with great respect and also to allow him to travel by military trains if the opportunity happened to offer itself.Mechanical engineering, like every other business pursuit, is directed to the accumulation of wealth; and as the attainment of any purpose is more surely achieved by keeping that purpose continually in view, there will be no harm, and perhaps considerable gain derived by an apprentice considering at the beginning the main object to which his efforts will be directed after learning his profession or trade. So far as an abstract principle of motives, the subject is of course unfit to consider in connection with engineering operations, or shop manipulation; but business objects have a practical application to be followed throughout the whole system of industrial pursuits, and are as proper to be considered in connection with machine-manufacturing as mechanical principles, or the functions and operation of machines.

FORE:There was nothing more to be done for the present. Ten minutes later Prout was knocking at the door of Lawrence's chambers.A pressure wheel, like a steam-engine, must include running contact between water-tight surfaces, and like a rotary steam-engine, this contact is between surfaces which move at different rates of speed in the same joint, so that the wear is unequal, and increases as the speed or the distance from the axis. When it is considered that the most careful workmanship has never produced rotary engines that would surmount these difficulties in working steam, it can hardly be expected they can be overcome in using water, which is not only liable to be filled with grit and sediment, but lacks the peculiar lubricating properties [41] of steam. A rotary steam-engine is in effect the same as a pressure water-wheel, and the apprentice in studying one will fully understand the principles of the other.

FORE:I took the little Amsterdam girl to my niece in the convent of the Sisters of Mercy, and went to an hotel myself. A German newspaper, bought at a bookstall, gave in gigantic type the information that Antwerp might fall at any moment, and a recently posted bulletin brought the feared-for news. But the people of Lige could not, and would not believe it.
