FORE:Such a proposition would constitute the first stage of an invention by demonstrating a fault in existing hammers, and a want of certain functions which if added would make an improvement.Dick, examining with the thoroughness of an expert, with Jeffs and his chums life perhaps depending on his care, stated that he saw no damage to the waterproofed coverings of the water supports. Declaring that they would stand by and watch the airplane, Sandy and Dick watched Larry and Jeff get settled, Dick spun the propeller to pump gas into the still heated cylinders, Jeff gave the switch-oncontact! call, Dick, pulling down on the prop, sprang aside to avoid its flailing blades, and the amphibians engine took up its roar.
FORE:We may, perhaps, find some suggestion of this combined distinctness and comprehensiveness in the aspect and configuration of Greece itself; in its manifold varieties of soil, and climate, and scenery, and productions; in the exquisite clearness with which the features of its landscape are defined; and the admirable development of coast-line by which all parts of its territory, while preserving their political independence, were brought into safe and speedy communication with one another. The industrial and commercial habits of the people, necessitating a well-marked division of labour and a regulated distribution of commodities, gave a further impulse in the same direction.
FORE:In studying improvements with a view to practical gain, a learner can have no reasonable hope of accomplishing much in fields already gone over by able engineers, nor in demonstrating anything new in what may be called exhausted subjects, such as steam-engines or water-wheels; he should rather choose new and special subjects, but avoid schemes not in some degree confirmed by existing practice.In this connexion, some importance must also be attributed to the more indirect influence exercised by children; These did not form a particularly numerous class in the upper ranks of Roman society; but, to judge by what we see in modern France, the fewer there were of them the more attention were they likely to receive; and their interests, which like those of the other defenceless classes had been depressed or neglected under the aristocratic rgime, were favoured by the reforming and levelling movement of the empire. One of Juvenals most popular satires is entirely devoted to the question of their education; and, in reference to this, the point of view most prominently put forward is the importance of the examples which are offered to them by their parents. Juvenal, himself a free-thinker, is exceedingly anxious that they should not be indoctrinated with superstitious opinions; but we may be sure that a different order of considerations would equally induce others to give their children a careful religious training, and to keep them at a distance from sceptical influences; while the spontaneous tendency of children to believe in the supernatural would render it easier to give them moral instruction under a religious form.
THREE:(1.) Why is the effect produced different on the top and bottom of a piece when struck by a hammer?(2.) Why does not a compound hammer create jar and concussion?(3.) What would be a mechanical difficulty in presenting the material to such hammers?(4.) Which is most important, speed or weight, in the effect produced on the under side of pieces, when struck by single acting hammers?
THREE:Beautiful hedges, which had been grown artificially in fine forms for years, fell under the blows of the hatchets. The reason? Before the day was over all hedges, all shrubs, and all trees had to be cut down, or the village would be set on fire. Still shaking and trembling in consequence of the terrors they had experienced during the day, old men, women, and children with red flushed cheeks joined in the work; they had not even taken time to change their Sunday- for their working-day clothes.
