TWO:Into the murky folds of the thick mist dived the seaplane.II.

TWO:"How you spoil that child," she said. "Hetty, take her away."��But��what?�� demanded Dick.

TWO:(1.) What does the term "machinery of transmission" include, as applied in common use?��(2.) Why cannot direct comparisons be made between shafts, belts, and gearing?��(3.) Define the relation between speed and strain in machinery of transmission.��(4.) What are the principal conditions which limit the speed of shafts?And neither is embittered by defeat;

TWO:Inherent or cooling strains in castings is much more intricate than shrinkage: it is, in fact, one of the most uncertain and obscure matters that pattern-makers and moulders have to contend with. Inherent strains may weaken castings, or cause them to break while cooling, or sometimes even after they are finished; and in many kinds of works such strains must be carefully guarded against, both in the preparation of designs and the arrangement of patterns, especially for wheels and pulleys with spokes, and for struts or braces with both ends fixed. The main difficulty resulting from cooling strains, however, is that of castings being warped and sprung; this difficulty is continually present in the foundry and machine-shop, and there is perhaps no problem in the whole range of mechanical manipulation of which there exists more diversity of opinion and practice than of means to prevent the springing of castings. This being the case, an apprentice can hardly hope for much information here. There is no doubt of springing and strains in castings being the result of constant causes that might be fully understood if it were not for the ever-changing conditions which exist in casting, both as to the form of pieces, the temperature and quality of metal, mode of cooling, and so on.��Captain Parks came up later with the real stones and while he waited for my wife to finish her costume, he examined the fire escape window and was sure that someone had entered and left by that.

TWO:We now pass to the consideration of Aristotle��s most important achievement��his system of logic. And as, here also, we shall find much to criticise, it is as well to begin by saying that, in our opinion, his contributions to the science are the most valuable ever made, and perhaps have done more to advance it than all other writings on the same subject put together.

TWO:A great share of the alleged improvements in machinery, when investigated will be found to consist in nothing more than the combination of several functions in one machine, the novelty of their arrangement leading to an impression of utility and increased effect.

TWO:I succeeded in laying my hands on an original copy of a proclamation that ought not to have been posted before the following day. I took the document with me to The Netherlands, and it is of special interest, because in it the Germans admit to have tyrannised the people, and to have not only burned Louvain, but also ransacked the town. The proclamation had been drawn up in concert with the German authorities and was approved by them. It was in French and in Flemish, and read as follows:He did not seem to mind much the destruction of the Halls with their world-famous wealth of books; anyway he spoke about it in an unconcerned tone. But he seemed to attach great importance to the safety of the town-hall. He said that when the buildings adjoining the town-hall began to burn, he had them blown up in order to keep the fire away from the beautiful monument.
