FORE:The force of gravity acts only in one directionvertically, so that the main force of hoisting and handling machinery which opposes gravity must also act vertically, while the horizontal movement of objects may be accomplished by simply overcoming the friction between them and the surfaces on which they move. This is seen in practice. A force of a hundred pounds may move a loaded truck, which it would require tons to lift; hence the horizontal movements of material may be easily accomplished by hand with the aid of trucks and rollers, so long as it is moved on level planes; but if a weight has to be raised even a single inch by reason of irregularity in floors, the difference between overcoming frictional contact and opposing gravity is at once apparent.
THREE:If a drawing is to be elaborate, or to remain long upon a board, the paper should be pasted down. To do this, first prepare thick mucilage, or what is better, glue, and have it ready at hand, with some slips of absorbent paper an inch or so wide. Dampen the sheet on both sides with a sponge, and then apply the mucilage along the edge, for a width of one-fourth or three-eighths of an inch. It is a matter of some difficulty to place a sheet upon a board; but if the board is set on its edge, the paper can be applied without assistance. Then, by placing the strips of paper along the edge, and rubbing over them with some smooth hard instrument, the edges of the sheet can be pasted firmly to the board, the paper slips taking up a part of the moisture from the edges, which are longest in drying. If left in this condition, the centre will dry first, and the paper be pulled loose at the edges by contraction before the paste has time to dry. It is therefore necessary to pass over the centre of the sheet with a wet sponge at intervals to keep the paper slightly damp until the edges adhere firmly, when it can be left to dry, and will be tight and smooth. In this operation much will be learned by practice, and a beginner should not be discouraged by a few failures. One of the most common difficulties in mounting sheets is in not having the gum or glue thick enough; when thin, it will be absorbed by the wood or the paper, or is too long in drying; it should be as thick as it can be applied with a brush, and made from clean Arabic gum, tragacanth, or fine glue.

FORE:Returning once more to Epicurus, we have now to sum up the characteristic excellences and defects of his philosophy. The revival of the atomic theory showed unquestionable courage and insight. Outside the school of Democritus, it was, so far as we know, accepted by no other thinker. Plato never mentions it. Aristotle examined and rejected it. The opponents of Epicurus himself treated it as a self-evident absurdity.208 Only Marcus Aurelius seems to have contemplated the possibility of its truth.209. But while to have maintained the right theory in the face of such universal opposition was a proof of no common discernment, we must remember that appropriating the discoveries of others, even when those discoveries are in danger of being lost through neglect, is a very different thing from making discoveries for ones self. No portion of the glory due to Leucippus and Democritus should be diverted to their arrogant successor. And it must also be remembered that the Athenian philosopher, by his theory of deflection, not only spoiled the original hypothesis, but even made it a little ridiculous."Go in and win," Balmayne whispered. "Always back your luck."

THREE:Designing is in many respects the same thing as invention, except that it deals more with mechanism than principles, although it may, and often does include both. Like invention, designing should always be attempted for the attainment of some definite object laid down at the beginning, and followed persistently throughout.

THREE:"Is that so? I beg your pardon, but won't you come with me? I suppose that you want a passport. I will take you to the commander."Being, then, is finite in extent, and, as a consequence of its absolute homogeneity, spherical in form. There is good reason for believing that the earths true figure was first discovered in the fifth century B.C., but whether it was suggested by the priori theories of Parmenides, or was19 generalised by him into a law of the whole universe, or whether there was more than an accidental connexion between the two hypotheses, we cannot tell. Aristotle, at any rate, was probably as much indebted to the Eleatic system as to contemporary astronomy for his theory of a finite spherical universe. It will easily be observed that the distinction between space and matter, so obvious to us, and even to Greek thinkers of a later date, had not yet dawned upon Parmenides. As applied to the former conception, most of his affirmations are perfectly correct, but his belief in the finiteness of Being can only be justified on the supposition that Being is identified with matter. For it must be clearly understood (and Zeller has the great merit of having proved this fact by incontrovertible arguments)17 that the Eleatic Being was not a transcendental conception, nor an abstract unity, as Aristotle erroneously supposed, nor a Kantian noumenon, nor a spiritual essence of any kind, but a phenomenal reality of the most concrete description. We can only not call Parmenides a materialist, because materialism implies a negation of spiritualism, which in his time had not yet come into existence. He tells us plainly that a mans thoughts result from the conformation of his body, and are determined by the preponderating element in its composition. Not much, however, can be made of this rudimentary essay in psychology, connected as it seems to be with an appendix to the teaching of our philosopher, in which he accepts the popular dualism, although still convinced of its falsity, and uses it, under protest, as an explanation of that very genesis which he had rejected as impossible.

THREE:And it is no wonder that the words of their great poet should read like a prophetic exposure of the terrors with which the religious revival, based on a coalition of philosophy and superstition, was shortly to overspread the whole horizon of human life.
