Still there had been no quarrel between the Whitford Maxfields and those of Duckwell. They came together so seldom that opportunities for quarrelling were rare. And Seth had too great a respect for such manifestations of Providential approbation as had been vouchsafed to his father, to be willing to break entirely with the old man. So, when old Max proposed to send Rhoda to the farm for a few weeks, he paying a weekly stipend for her board, his son and his son's wife had at once agreed to the proposition. And as they were not persons who brought their religious theories into the practical service of daily life, Rhoda's conscience was not disturbed by having a high and stern standard of duty held up for her attainment at every moment. XIII FIRST FLIERS IN ENGLAND What a wind there must be, to make the door bang like that! exclaimed Betty Grimshaw, when the loud sound above recorded reached her ears. A study of the development of the helicopter principle was published in France in 1868, when the great French engineer Paucton produced his Th茅orie de la Vis d鈥橝rchim茅de. For some inexplicable reason, Paucton was not satisfied with the term 鈥榟elicopter,鈥?but preferred to call it a 鈥榩t茅rophore,鈥?a name which, so far as can be ascertained, has not been adopted by any other writer or investigator. Paucton stated that, since a man is capable of sufficient force to overcome the weight of his own body, it is only necessary to give him a machine which acts on the air 鈥榳ith all the force of which it is capable and at its utmost speed,鈥?and he will then be able to lift himself in the air, just as by the exertion of all his strength he is able to lift himself in water. 鈥業t would seem,鈥?says Paucton, 鈥榯hat in the pt茅rophore, attached vertically to a carriage, the whole built lightly and carefully assembled, he has found something that will give him this result in all perfection. In construction, one would be careful that the machine40 produced the least friction possible, and naturally it ought to produce little, as it would not be at all complicated. The new D?dalus, sitting comfortably in his carriage, would by means of a crank give to the pt茅rophore a suitable circular (or revolving) speed. This single pt茅rophore would lift him vertically, but in order to move horizontally he should be supplied with a tail in the shape of another pt茅rophore. When he wished to stop for a little time, valves fixed firmly across the end of the space between the blades would automatically close the openings through which the air flows, and change the pt茅rophore into an unbroken surface which would resist the flow of air and retard the fall of the machine to a considerable degree.鈥?
