By examining the history of great achievements in the mechanic arts, it will be seen that success has been mainly dependent upon predicting future wants, as well as upon an ability to supply such wants, and that the commercial value of mechanical improvements is often measured by conditions that the improvements themselves anticipate. The invention of machine-made drills, for example, was but a small matter; but the demand that has grown up since, and because of their existence, has rendered this improvement one of great value. Moulded bearings for shafts were also a trifling improvement when first made, but it has since influenced machine construction in America in a way that has given great importance to the invention.

In those first days many civilians were killed, and not only in Vis, but still more in the surrounding villages, Mouland and Berneaux, which were soon burnt down and where many a good man was brought low by the murderous bullets. The savage soldiers killed the cattle also, and a large number of carcases had been lying about for days.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.

THREE:The expense of patterns should be divided among and charged to the machines for which the patterns are employed, but there can be no constant rules for assessing or dividing this cost. A pattern may be employed but once, or it may be used for years; it is continually liable to be superseded by changes and improvements that cannot be predicted beforehand; and in preparing patterns, the question continually arises of how much ought to be expended on thema matter that should be determined between the engineer and the pattern-maker, but is generally left to the pattern-maker alone, for the reason that but few mechanical engineers understand pattern-making so well as to dictate plans of construction.

THREE:This code Plato set himself to construct in his last and longest work, the Laws. Less than half of that Dialogue, however, is occupied with the details of legislation. The remaining portions deal with the familiar topics of morality, religion, science, and education. The first book propounds a very curious theory of asceticism, which has not, we believe, been taken up by any subsequent moralist. On the principle of in vino veritas Plato proposes that drunkenness should be systematically employed for the purpose of testing self-control. True temperance is not abstinence, but the power of resisting temptation; and we can best discover to what extent any man possesses that power by surprising him when off his guard. If he should be proof against seductive influences even when in his cups, we shall be doubly sure of his constancy at other times. Prof. Jowett rather maliciously suggests that a personal proclivity may have suggested this extraordinary apology for hard drinking. Were it so, we should be reminded of the successive revelations by which indulgences of another kind were permitted to Mohammed, and of the one case in which divorce was sanctioned by Auguste Comte. We should also remember that the Christian Puritanism to which Plato approached so near has always been singularly lenient to this disgraceful vice. But perhaps a somewhat higher order of considerations will help us to a better under270standing of the paradox. Plato was averse from rejecting any tendency of his age that could possibly be turned to account in his philosophy. Hence, as we have seen, the use which he makes of love, even under its most unlawful forms, in the Symposium and the Phaedrus. Now, it would appear, from our scanty sources of information, that social festivities, always very popular at Athens, had become the chief interest in life about the time when Plato was composing his Laws. According to one graceful legend, the philosopher himself breathed his last at a marriage-feast. It may, therefore, have occurred to him that the prevalent tendency could, like the amorous passions of a former generation, be utilised for moral training and made subservient to the very cause with which, at first sight, it seemed to conflict.
FORE:But it was not for long that Hetty remained like that. There was much to be done yet and much to learn. The thought of Gordon spurred her on. If she could get this woman into her power and force her to speak, all would be well. Hetty never doubted for a moment that Leona Lalage was at the bottom of her lover's misfortunes.

FORE:Before those on the Naamsche Vest found out their mistake, the shooting was going on in the144 greater part of the town, and the excited men, who at first had been shooting at each other, soon joined the rest. Some wounded troopers were taken to one of the convents on the Vest, but a couple of hours later they were suddenly fetched away again.

The latter seems a plausible theory, and perhaps a correct one; but there are two facts in connection with the operation of reaction water-wheels which seem to controvert the latter and favour the first theory, namely, that reaction wheels in actual practice seldom utilise more than forty per cent. of useful effect from the water, and that their speed may exceed the initial velocity of the water. With this the subject is left as one for argument or investigation on the part of the reader.Never mind old Suspicious Sandy, urged Dick. Let him read that, but you tell us."You have been so long," she said, pitifully, "so very long. And why didn't you come when I heard you standing by the door."Yet I am glad to have witnessed the terrible fights near the Yser a couple of times where the German invasion was stopped, and where we may hope that soon victory may dawn on the brave Belgian army.Then there was the voice of Balmayne in a key of mirth. The front door was opened, the call of a cab whistle thrilled down the street. It was almost as if there were two sets of people in the house, one family given over to the dark and gloomy, the other all comedy and smiles.They constantly heard the boom, boom of the shells exploding near by, and each time thought that their last hour had struck. The gloomy cellar depressed them still more, and nobody really believed that there was any chance of being saved. So the44 little sisters prayed on, preparing each other for death, and looking for the approaching end in quiet resignation.All moving parts must of course be independent of fixed parts, the relation between the two being maintained by what has been called running joints.
