THREE:Group after group went by, and I heard French and Netherland, the Maastricht vernacular and sweet Flemish spoken, all sorts of tongues and modes of utterance. The men were bare-headed, and each let his rosary slip through his fingers. Soon after the head of the procession reached Our Lady Square the huge church was packed, and those who could not find room inside stood in the square, which also very soon was full with these thousands of people in a dense mass, like so many blades of grass in a meadow."Well, so I can," Isidore smiled. "I am not going to offer to lend that young man money, because that would wound his pride. Besides, there will be no occasion. Now, can you let me know the name of Bruce's creditor."
FORE:In such sciences as rest in any degree upon physical experiment, like chemistry, to experiment without some definite object may be a proper kind of research, and may in the future, as it has in the past, lead to great and useful results; but in mechanics the case is different; the demonstration of the conservation of force, and the relation between force and heat, have supplied the last link in a chain of principles which may be said to comprehend all that we are called upon to deal with in dynamical science, and there remains but little hope of developing anything new or useful by discovery alone. The time has been, and has not yet passed away, when even the most unskilled thought their ability to invent improvements in machinery equal with that of an engineer or skilled mechanic; but this is now changed; new schemes are weighed and tested by scientific standards, in many cases as reliable as actual experiments. A veil of mystery which ignorance of the physical sciences had in former times thrown around the mechanic arts, has been cleared away; chance discovery, or mechanical superstition, if the term may be allowed, has nearly disappeared. Many modern engineers regard their improvements in machinery as the exercise of their profession only, and hesitate about asking for protective grants to secure an exclusive use of that which another person might and often does demonstrate, as often as circumstances call for such improvement. There are of course new articles of manufacture to be discovered, and many improvements in machinery which may be proper subject matter for patent rights; improvements which in all chance would not be made for the term of a patent, except by the inventor; but such cases are rare; and it is fair to assume that unless an invention is one which could not have been regularly deduced from existing data, and one that would not in all probability have been made for a long term of years by any other person than the inventor, such an invention cannot in fairness become the property of an individual without infringing the rights of others.The prevailing custom of casting machine frames in one piece, or in as few pieces as possible, leads to a great deal of bar-boring, most of which can be performed accurately enough by boring bars supported in and fed through bearings. By setting up temporary bearings to support boring-bars, and improvising means of driving and feeding, most of the boring on machine frames can be performed on floors or sole plates and independent of boring machines and lathes. There are but few cases in which the importance of studying the principles of tool action is more clearly demonstrated than in this matter of boring; even long practical experience seldom leads to a thorough understanding of the [139] various problems which it involves.

TWO:A remarkable strike had taken place in the Leo XIII Hospital. The head of this institution, Dr. Tits, also had been taken as a hostage. It was the most blackguardly act one can think of, to take away the man who had spent night and day mostly nursing wounded Germans. Dr. Noyons found it so harsh that he took counsel with the other doctors, and they decided not to resume work before Dr. Tits came back. This of course happened immediately.
TWO:CHAPTER LXI. LOGIC.
TWO:Considered as a mechanical agent, a hammer concentrates the power of the arms, and applies it in a manner that meets the requirements of various purposes. If great force is required, a long swing and slow blows accomplish tons; if but little force is required, a short swing and rapid blows will servethe degree of force being not only continually at control, but also the direction in which it is applied. Other mechanism, if employed instead of hammers to perform a similar purpose, would require to be complicated [104] machines, and act in but one direction or in one plane.
