... the newspapers, and the whole story of wrongful discharge, unlawful arrest and insulting treatment of the strikers by the police began to filter into the public mind through the columns of the daily press.

... rain-water from a sufficiently wide area would be exhausted even in the hot months; but the cisterns had to be protected from the direct rays of the sun as well as from impurities. The former was effected by providing the cisterns with covering and shelter; the second by making the rain-water filter through layers, several yards thick, of sand and gravel. The natural water-holes, which are found in all deserts, but which dry up in times of protracted drought, indicated the spots where it would be most ...

... began to read. He read as he always read in moments of excitement, blurring through with a glance. But though the old man's writing was distinct and almost insolent in its boldness, the portent of the written words did not filter through at once to his understanding. He frowned and read again. Once more he read, pacing the floor with unquiet eyes. A number of things were becoming clearer. There was in the first place no mention of the fugitive nephew. Joan was the ...

Her petticoat of striped white and blue, torn and discolored, falls only just below the knees, leaving her legs bare; her bluish apron drips and smells of the brine like a filter; and her bare feet in contrast with the brown color that the sun has given her flesh, are singularly pallid, like the roots of aquatic plants. And her voice is limpid and childish; and some of the words that she speaks seem to light up her ingenuous ...

... remain for several days exposed to the fierce sun. Then they are thrown into a great central well, where the climate soon converts them into dust. This is washed by the rains into underground wells. Charcoal in these wells serves to filter the rain water before it enters the ground.

No expense is spared by the Parsees in the construction of these towers of silence, which are always placed on the tops of hills. According to the testimony of some ...

... the whole? that the whole is more or less than the sum of the parts? As for the puddle of life, the stench is offensive to you? Well, and what then? Do you not live in it? Why do you not make it clean? Do you clamour for a filter to make clean only your own particular portion? And, made clean, are you wroth because Kipling has stirred it muddy again? At least he has stirred it healthily, with steady vigour and good-will. He ...

... supply no new energy, but make the body they are turned upon supply its own, using the energy of its own random molecular motion of heat, they are practically impossible to stop. The energy necessary for molecular rays to take effect is so small that the usual type of filter lets enough of it pass. A ship equipped with filters is no better off when attacked than one without. The rays simply drove the front end into the rear, or vice versa, or tore it to pieces as the pirates desired. The Rocket Patrol could kill off the ...

Boil it for half an hour in a Florence flask, or in a tin sauce-pan; let it stand to subside, and filter it through paper. My friend Mr. Greene, a surgeon at Brewood in Staffordshire, assured me, that he had cured in one season agues without number with this saturated solution; that he found ten drops from a two-ounce phial given thrice a day was a full dose for a grown person, ...

... wickedness, and then Frederick would need supporting—on helping the poor. The parish flourished because, to take a handful at random, of the ill-behavior of the ladies Du Barri, Montespan, Pompadour, Ninon de l'Enclos, and even of learned Maintenon.

Sages after sages strove, In vain, to filter off a crystal draught Pure from the lees, which often more enhanced The thirst than slaked it, and not seldom bred Intoxication and delirium wild. In vain they pushed inquiry to the birth And spring-time of the world; asked, Whence is man? Why formed at all? ...

... Joe had never noticed, before, the minute noises of the air pressure apparatus strapped to his back. His exhaled breath went to a tiny pump that forced it through a hygroscopic filter which at once extracted excess moisture and removed carbon dioxide. The same pump carefully measured a volume of oxygen equal to the removed CO2 and added it to the air it released. The pump made very small sounds indeed, and the valves were ...

With the lamentable effect of the evil of bad water experienced in the South African war, the Authorities have been most drastic in their insistence of a pure water supply to the Army.

The selection of a site for the little cemetery is most judicious, several little streams from the heights in the rear filter through the ground, producing a moisture calculated to prevent decomposition and explanatory of the singular appearance of the bodies disinterred there in 1855.

Usually no underdrains will be needed unless the ground water gets up to within three feet of the surface, and, in a number of cases, underdrains have been laid under a sewage filter at considerable expense, only to find when the filter was in operation that they were never in use. In clay soils the underdrain is not necessary. In fact, it may be noticed that the underdrain is not for the purpose of taking care of the sewage, but rather of draining off the soil-water ...

Instead of framing laws so that wealth and power would get into the hands of a small number of individuals, in the expectation that prosperity would filter down to the many, the advocate of public interest would aim his legislation directly at what he considers the needs of the less powerful classes. He would interfere with the railroads, for example, ...

The ecstasy will fail, the will to renunciation falter; the gray reality which permits no one to escape it altogether will filter like a mist into the vision and the cell. Then they will turn to the wise men. They will find comfort in the smile to which they could not frame their own lips, and discover in it more sympathy than they could ...

... Jesus at all, but that his personality is simply a myth that gradually grew up in the minds of some Jewish fanatics who sought a fulfilment of Messianic prophecy. We might treat these perverse and subversive conclusions as only curious instances of a wrong method of criticism. But they filter down from the scholars to the masses of Christian believers and weaken their faith. It becomes a duty to deal with the method which leads to such results, and threatens to destroy all our missionary zeal. Hence I proceed to test the value of the method itself, even though ...
