TWO:An apprentice may get a clear idea of this venting process by inspecting tubular core barrels, such as are employed in moulding pipes or hollow columns, or by examining ordinary cores about a foundry. Provision of some kind to 'carry off the vent,' as it is termed by moulders, will be found in every case. The venting of moulds is even more important than venting cores, because core vents only carry off gas generated within the core itself, while the gas from its exterior surface, and from the whole mould, has to find means of escaping rapidly from the flasks when the hot metal enters.Instantly the situation became clear to the Sky Patrol.

- THREE:A gravity wheel must have a diameter equal to the fall of water, or, to use the technical name, the height of the head. The speed at the periphery of the wheel cannot well exceed sixteen feet per second without losing a part of the effect by the wheel anticipating or overrunning the water. This, from the large diameter of the wheels, produces a very slow axial speed, and a train of multiplying gearing becomes necessary in order to reach the speed required in most operations where power is applied. This train of gearing, besides being liable to wear [38]and accident, and costing usually a large amount as an investment, consumes a considerable part of the power by frictional resistance, especially when such gearing consists of tooth wheels. Gravity wheels, from their large size and their necessarily exposed situation, are subject to be frozen up in cold climates; and as the parts are liable to be first wet and then dry, or warm and cold by exposure to the air and the water alternately, the tendency to corrosion if constructed of iron, or to decay if of wood, is much greater than in submerged wheels. Gravity wheels, to realise the highest measure of effect from the water, require a diameter so great that they must drag in the water at the bottom or delivering side, and are for this reason especially affected by back-water, to which all wheels are more or less liable from the reflux of tides or by freshets. These disadvantages are among the most notable pertaining to gravity wheels, and have, with other reasonssuch as the inconvenience of construction, greater cost, and so ondriven such wheels out of use by the force of circumstances, rather than by actual tests or theoretical deductions.

TWO: He has become keen and shrewd; he has learned how to flatter his master in word and indulge him in deed; but his soul is small and unrighteous. His slavish condition has deprived him of growth and uprightness and independence; dangers and fears which were too much for his truth and honesty came upon him in early years, when the tenderness of youth was unequal to them, and he has been driven into crooked ways; from the first he has practised deception and retaliation, and has become stunted and warped. And so he has passed out of youth into manhood, having no soundness in him, and is now, as he thinks, a master in wisdom.128
TWO:"Tell him the news abruptly," he said. "And when the man has digested that, show him the photograph. It is a recent one of Countess Lalage. I want to know if he recognises her."The monotheism of the Jehovist religion would seem to have marked it out as the natural faith of a universal empire. Yet, strange to say, it was not by this element of Judaism that proselytes were most attracted. Our authorities are unanimous in speaking of the sabbath-observance as the most distinguishing trait of the Jews themselves, and the point in which they were most scrupulously imitated by their adherents; while the duty of contributing to the maintenance of the temple apparently stood next in popular estimation. But if this be true, it follows that the liberation of the spiritualistic element in Judaism from its ceremonial husk was a less essential condition to the success of Christianity than some have supposed. What the world objected to in Judaism was not its concrete, historical, practical side, but its exclusiveness, and the hatred for other nations which it was supposed to breed. What the new converts wished was to take the place of the Jews, to supersede them in the divine favour, not to improve on their law. It was useless to tell them that they were under no obligation to observe the sabbath, when the institu219tion of a day of rest was precisely what most fascinated them in the history of Gods relations with his chosen people. And it was equally useless to tell them that the hour had come when the Father should not be worshipped any more at Jerusalem but everywhere in spirit and in truth, when Jerusalem had become irrevocably associated in their minds with the establishment of a divine kingdom on this earth. Thus, while the religion of the Middle Ages reached its intensest expression in armed pilgrimages to Palestine, the religion of modern Puritanism has embodied itself by preference in the observance of what it still delights to call the sabbath.
