ONE:A planing machine with a running platen occupies nearly twice as much floor space, and requires a frame at least one-third longer than if the platen were fixed and the tools performed the cutting movement. The weight which has to be traversed, including the carriage, will in nearly all cases exceed what it would be with a tool movement; so that there must exist some very strong reasons in favour of a moving platen, which I will now attempt to explain, or at least point out some of the more prominent causes which have led to the common arrangement of planing machines.The history of Greek philosophy, whether conceived in this comprehensive sense or as an erudite investigation into matters of detail, is a province which the Germans have made peculiarly their own; and, among German scholars, Dr. Zeller is the one who has treated it with most success. My obligations to his great work are sufficiently shown by the copious references to it which occur throughout the following pages. It is in those instancesand they are, unfortunately, very numerouswhere our knowledge of particular philosophers and of their opinions rests on fragmentary or second-hand information, that I have found his assistance most valuable. This has especially been the case with reference to the pre-Socratic schools, the minor successors of Socrates, the earlier Stoics, the Sceptics, and the later Pythagoreans. I must, however, guard against the supposition that my work is, in any respect, a popularisation or abridgment of Zellers. To popularise Zeller would, indeed, be an impertinence, for nothing can be more luminous and interesting than his style and general mode of exposition. Nor am I playing the part of a finder to a large telescope; for my point of view by no means coincides with that of the learned German historian. Thus, while my limits have obliged me to be content with a very summary treatment of many topics which he has discussed at length, there are others, and those, in my opinion, not the least important, to which he has given less space than will be found allotted to them here. On several questions, also, I have ventured to controvert his opinions, notably with reference to the Sophists, Socrates, Aristotle, and Plotinus. My general way of looking at the Greeks and their philosophy also differs from his. And the reasons which have led me to follow an independent course in this respect involve considerixations of such interest and importance, that I shall take the liberty of specifying them in some detail.

Have there been any other signs and manifestations?"Cores are employed mainly for what may be termed the displacement of metal in moulds. There is no clear line of distinction between cores and moulds, as founding is now conducted; cores may be of green sand, and made to surround the exterior of a piece, as well as to make perforations or to form recesses within it. The term 'core,' in its technical sense, means dried moulds, as distinguished from green sand. Wheels or other castings are said to be cast in cores when the moulds are made in pieces and dried. Supporting and venting cores, and their expansion, are conditions to which especial attention [95] is called. When a core is surrounded with hot metal, it gives off, because of moisture and the burning of the 'wash,' a large amount of gas which must have free means of escape. In the arrangement of cores, therefore, attention must be had to some means of venting, which is generally attained by allowing them to project through the sides of the mould and communicate with the air outside.
THREE:When Larry rejoined Jeff, he flung the life preserver into the space behind the control seat of the amphibian, leaving it there without comment as he helped Jeff to lift and drop the still unconscious man into his own forward place.Presently he walked to an old soap box holding metal odds and ends, washers, bolts and so on. This he up-ended. He sat down, his lean jaws working as he chewed his own gum slowly. Around him, like three detectives watching the effect of a surprise accusation, stood the chums.
