Mrs. Unwin

“ Last night, however, quite contrary to my expectations, the fever left me entirely, and I slept quietly, soundly, and long. If it please God that it return not, I shall soon find myself in a condition to proceed. I walk constantly, that is to say, Mrs. Unwin and I together; for at these times I keep her continually employed, and never suffer her to be absent from me many minutes. She gives me all her time and all her attention, and forgets that there is another object in the world. ”

“ Unwin to see you without any preparation. Clarke will have a talk with his father first, and then come back for you. Let me hope it will be with a welcome that will make amends to you for your long years of orphanage among us.”
“You are very good,” came from the trembling lips of the young girl. Mrs. Unwin’s grace and unconscious dignity always abashed her.
“Clarke informs me that you are not lacking in that same desirable quality,” whispered the other lady, and with a smile which gave an air of pathos to her faded yet beautiful face, she turned away and followed her son out into the hall. ”

“ From these sources of inquiry it appears that Lady Austen was a woman of great wit and vivacity, and possessed the power of exciting much interest by her manner and conversation—that Mrs. Unwin, who was of a more sedate and quiet character, seeing the ascendency that Lady Austen thus acquired, became jealous, and that a rupture was the consequence. Mr. Andrews, an intelligent inhabitant of Olney, who is my informant, assured me that such was the substance of the case, and that the rest was mere surmise and conjecture. ”

“ But beyond and back of all this was some secret joy, unintelligible to the nurse, which helped rather than retarded the sick girl’s recovery, and made Carmel appear at times as if she walked on air and breathed the very breath of Paradise—an anomaly which not only roused Miss Unwin’s curiosity, but led her to regard with something like apprehension, any change in her patient’s state of mind which would rob her of the strange and unseen delights which fed her secret soul and made her oblivious of the awful facts awaiting a restored memory. ”

“ I could not feel free under a burden of debt incurred for something whose value is yet to be tested. I cannot be beholden to any one for a start which is as likely to lead to failure as to success.”
“Not if that person is your promised wife?” burst from trembling and eager lips behind him, and Polly, accompanied by Mrs. Unwin, who had mistaken the ring of the bell for the signal which had been established between herself and Clarke, stepped into the room, and advanced with timid steps but glowing cheeks into the presence of the equally astonished son and father. ”

“ Unwin's influence produced the Moral Satires. The Task was born of a more potent inspiration. One day Mrs. Jones, the wife of a neighbouring clergyman, came into Olney to shop, and with her came her sister, Lady Austen, the widow of a Baronet, a woman of the world, who had lived much in France, gay, sparkling and vivacious, but at the same time full of feeling even to overflowing. The apparition acted like magic on the recluse. ”

“ The old man—for Frederick Unwin was twenty years older than his wife—grew so pale that his son became seriously alarmed.
“You are sick—fainting,” he cried; “let me call someone.” But a glance from his father’s commanding eye held him where he stood.
“No, no; it is from shame, Clarke, possibly from grief. You have been on the whole a good boy, and I have taken pride in you. To leave you with your hopes dashed, and the care of a mother on your hands, is a humiliation I never expected. I—I have lost all, Clarke, and am, besides, in debt. ”

“ Grace Unwin had been a mother to Clarke for thirteen years, and she loved him devotedly.
“Clarke,” said she, “I dread this ordeal most unaccountably. Your father has had something on his mind of late. Do you know of any trouble weighing upon him besides this dreadful one of leaving us?”
“No,” rejoined the wondering youth. “He has never confided in me, mother, as much as he has in you. If you know nothing—”
“And I do not,” she murmured.
“You must have been deceived by your affection. He is not the man to brood over petty troubles, or to be cast down by matters he could regulate with a word.” ”

“ Clarke Unwin had not visited the Earle cottage since Ephraim took up his abode in it. Polly had refused to go there, and he himself felt no call to intrude upon a man who was personally disagreeable to him, and whom he could not but regard as a tyrant to the sweet girl whose life had been all sunshine till this man came into it with his preposterous demands and insatiable desire for money. ”

“ Instantly he responded to her wish and they passed the house with quick and agitated steps, but when the shadows of the next block had absorbed them, they both paused as it were simultaneously, and the doctor said with something more than his usual feeling in his thin, fine voice, “Do you care for Clarke Unwin, little one?”
Her answer struck him.
“Do I care for breath, for life? He has been both to me ever since I could remember anything. And now he cares for me.” ”

“ Clarke Unwin was no ordinary man. He was the thoughtful son of a proud reserved father, and he had an aim in life quite apart from the accumulation of wealth, which had so distinguished the elder man. He was ambitious of becoming a famous electrician and had already shown sufficient talent in this direction for his friends to anticipate great results from his efforts. ”

“ One person only was a perfect stranger to Clarke, but him he scarcely noticed, so intent was he on his errand and the desire he had of speaking to Mr. Earle alone.
“Hurrah! Come! Here’s Clarke Unwin!” shouted a voice from the depths of the smoky pall. “Brought your flute with you? Nobody comes here without some means of entertaining the company.”
“Off with your coat; there’s snow sticking to it! Uh! You’ve robbed the room of all the heat there was in it,” grumbled old Cheeseborough, whose fretfulness nobody minded because of the good nature that underlay it.
“Freedom Hall, this!” ”

“ In some cases, as at Niagara, the hydraulic power can only be economically developed in very large units, and it can be most conveniently subdivided and distributed by transformation into electrical energy. Partly from the development of new industries such as paper-making from wood pulp and electro-metallurgical processes, which require large amounts of cheap power, partly from the facility with which energy can now be transmitted to great distances electrically, there has been a great increase in the utilization of water-power in countries having natural waterfalls. ”

“ It is not likely that any formula can be found which will give exactly the discharge of any given pipe. For one of the chief factors in any such formula must express the exact roughness of the pipe surface, and there is no scientific measure of roughness. The most that can be done is to limit the choice of the coefficient for a pipe within certain comparatively narrow limits. The experiments on fluid friction show that the power of the velocity to which the resistance is proportional is not exactly the square. ”

“ Izard has confessed his sins, and now let the impostor confess his. Who are you, man, and how happens it that you know all our ways and the whole history of this town?” And Lawyer Crouse shook the would-be Earle by the arm and would not let him go till he answered.
“I am—” the old bravado came back, and the fellow for a moment looked quite reckless and handsome. “Ask Tilly Unwin who I am,” he suddenly shouted, breaking into a great laugh. ”

“ Gina, who had silently disposed her lithe, snake-like, supple figure on a little sofa, looked round with astonishment at her fiancé.
"Oh, we may call it love of a third type," answered Madame Wildenhofif: "love sanctioned by law, the union of two souls in friendship, and the bringing forth of rachitic off-spring: an abnormal combination of brute and human love."
"Do you then, Madame," urged Owinski, "perceive no good points in marriage?"
"None whatever," she replied with a bland smile, "because—and this reason alone would suffice me—because I hate marriage with all my heart. ”

“ If in one part of its course the velocity of a stream is great enough to scour the bed and the water becomes loaded with silt, and in a subsequent part of the river’s course the velocity is diminished, then part of the transported material must be deposited. Probably deposit and scour go on simultaneously over the whole river bed, but in some parts the rate of scour is in excess of the rate of deposit, and in other parts the rate of deposit is in excess of the rate of scour. Deep streams appear to have the greatest scouring power at any given velocity. ”

“ The motor itself, of one of the kinds to be described presently, which either overcomes a useful resistance directly, as in the case of a ram acting on a lift or crane chain, or indirectly by actuating transmissive machinery, as when a turbine drives the shafting, belting and gearing of a mill. With the motor is usually combined regulating machinery for adjusting the power and speed to the work done. ”

“ Miss Lavinia adjusted her spectacles on her high Roman nose, the better to annihilate with a flashing glance the persistent young lady whom she felt dimly persuaded in her own mind was "laughing in her sleeve at her," and Mrs. Winans, with the pearly edge of one little tooth repressing the smile that wanted to dimple on her lip, sat demurely expectant.
"I did not call on you, Mrs. Winans, I assure you, to solicit a situation as seamstress. I never allow myself to be brought into personal contact with the filthy and odious poor. ”

“ Relative Value of Different Materials for Submerged Works.—That the power of water to remove and transport different materials depends on their density has an important bearing on the selection of materials for submerged works. In many cases, as in the aprons or floorings beneath bridges, or in front of locks or falls, and in the formation of training walls and breakwaters by pierres perdus, which have to resist a violent current, the materials of which the structures are composed should be of such a size and weight as to be able individually to resist the scouring action of the water. ”

“ When a stream of fluid in steady motion impinges on a solid surface, it presses on the surface with a force equal and opposite to that by which the velocity and direction of motion of the fluid are changed. Generally, in problems on the impact of fluids, it is necessary to neglect the effect of friction between the fluid and the surface on which it moves. ”

“ Properties of Fluids.—The fluids to which the laws of practical hydraulics relate are substances the parts of which possess very great mobility, or which offer a very small resistance to distortion independently of inertia. Under the general heading Hydromechanics a fluid is defined to be a substance which yields continually to the slightest tangential stress, and hence in a fluid at rest there can be no tangential stress. ”

“ The development of electrical methods of transmitting and distributing energy has led to the utilization of many natural waterfalls so situated as to be useless without such a means of transferring the power to points where it can be conveniently applied. ”

“ In many cases the natural fall can be increased by a dam or weir thrown across the stream. The engineer will also examine to what extent the head will vary in different seasons, and whether it is necessary to sacrifice part of the fall and give a steep slope to the tail race to prevent the motor being drowned by backwater in floods. Streams fed from lakes which form natural reservoirs or fed from glaciers are less variable than streams depending directly on rainfall, and are therefore advantageous for water-power purposes. ”

“ If at a given point a in space, the particles of water always arrive with the same velocity and in the same direction, during any given time, then the motion is termed steady motion. On the contrary, if at the point a the velocity or direction varies from moment to moment the motion is termed unsteady. A river which excavates its own bed is in unsteady motion so long as the slope and form of the bed is changing. ”

“ To produce a flood the rainfall must be heavy and widely distributed, and to produce a flood of exceptional height the duration of the rainfall must be so great that the flood waters of the most distant affluents reach the point considered, simultaneously with those from nearer points. The larger the catchment basin the less probable is it that all the conditions tending to produce a maximum discharge should simultaneously occur. Further, lakes and the river bed itself act as storage reservoirs during the rise of water level and diminish the rate of discharge, or serve as flood moderators. ”

“ Axial flow turbines with vertical shafts have the disadvantage that in addition to the weight of the turbine there is an unbalanced water pressure to be carried by the footstep or collar bearing. In radial flow turbines the hydraulic pressures are balanced. The application of turbines to drive dynamos directly has involved some new conditions. The electrical engineer generally desires a high speed of rotation, and a very constant speed at all times. The reaction turbine is generally more suitable than the impulse turbine. ”
