"Slag" Quotes from Famous Books



... perfectly smooth grassy plain, about a league square, and shaped like a horse-shoe, opened before us, encompassed by bare cinder-like hills, that rose round—red, black, and yellow—in a hundred uncouth peaks of ash and slag. Not a vestige of vegetation relieved the aridity of their vitrified sides, while the verdant carpet at their feet only made the fire-moulded circle seem more weird and impassable. Had I had a trumpet and a lance, I ...

... from excess of carbon by adding broken lumps of pure hematite or magnetite iron ore. This causes a violent boiling, which is kept up until the metal becomes soft enough, when it is allowed to stand to let the metal clear from the slag which floats in scum upon the top. The separation of the slag and iron is facilitated by throwing in some lime from time to time. Spiegel, or specular iron, is then added; about 1 per cent. more than in the scrap ...

... pick up my marbles I look around for either an Elysium field or a slag heap but instead a creep is staring down at me. He looks part human and part beetle and has a face the color of the meat of an avocado. His head is shaped like a pear standing on its stem and has two eyes spaced about six inches ...

... with reeds and rushes and stagnant pools of water. The site of the world-renowned hanging gardens is now marked by a series of nondescript lumps. The great temple of Marduk is a dusty heap of brick rubbish, and the Palace of Nebuchadnezzar appears as a mean slag heap looking down upon a ...

... pea. When found in the gravel bank, it is frequently mixed with clay, etc., and it cannot be used in this condition for a roof, but must be washed. The utensils necessary for this purpose are of so simple and suggestive a nature that they need not be described. Slag is being successfully used in place of the gravel. It is easily reduced to suitable size, by letting the red hot mass, as it runs from the furnace, run into a vessel with water. The sudden chilling of the slag causes it to burst into fragments of a ...

... situated on the north bank of the Tyne, about eight miles west of Newcastle. The Newcastle and Carlisle railway runs along the opposite bank; and the traveller by that line sees the usual signs of a colliery in the unsightly pumping-engines surrounded by heaps of ashes, coal-dust, and slag; whilst a neighbouring iron-furnace in full blast throws out dense smoke and loud jets of steam by day and lurid flames at night. These works form the nucleus of the village, which is almost entirely occupied by coal-miners ...

Never venturing a caveat whatever may betide, Though functionally ...

... not a cheering prospect. Through the growing gloom there pulsed the red glow of the furnaces on the sides of the hills. Great heaps of slag and dumps of cinders loomed up on each side, with the high shafts of the collieries towering above them. Huddled groups of mean, wooden houses, the windows of which were beginning to outline themselves in light, were scattered here and there along the line, and the frequent ...

... great manufactory of the iron brought from the Forest of Dean. The metal was brought up the Severn by barges, to the quay which stood at the road running straight down from Longsmith Street (in which Charles Hoar's house stands), and buried under all this street we find the cinder and slag of the Roman forges. In Domesday book (which was ordered to be drawn up at a Parliament in Gloucester in 1083) it states that the City had paid to the King (i. e., Edward the Confessor) ten dicres of iron yearly. This is very remarkable, for a dicre was three dozen ...

... common mortar, as well as in sawdust, ashes and powdered charcoal, quite enough to serve as non-conductors of heat and of moisture too, if properly protected. One of the best and most available materials at present known for this purpose is 'mineral wool,' a product of iron 'slag.' If the open spaces between the studs and rafters of a wooden building (or in a brick building between the furrings) are filled with this substance, or anything else equally good, if there is anything else—of course sawdust or other inflammable material ...

... chamber is used continuously, it should be jacketed with slag wool or boiler composition, but for many purposes this is no advantage. As an example both ways, I will instance the drying of founders' cores where there is only one blow per day. The cores of an ordinary foundry can be dried by gas in a common sheet iron even in about half an hour; ...

... but many persons enjoy the excursion, over what at first sight seems to be a plain of lava, though as there is no volcano visible, one is a little at fault in divining from whence it came. We were told finally that it was slag from the workings of the mines at Eulalia, and that more modern processes of disintegration and amalgamation might extract good pay in silver from these "tailings," now spread broadcast for many miles on the surface of ...

... very good footing," said Philippe. "In one sense the rocks are loose, for the whole side of the mountain where we go up is formed of slag and scoriae. But then the pieces are wedged together, so as not to move much, and the foot clings to them, so that you don't slip. On the whole, it is good footing. The only difficulty is, it is so steep. It is a thousand feet up ...

This immense caldron, two and three quarter miles in circumference, is filled to within twenty feet of its brim with red molten lava, over which lies a thin scum resembling the slag on a smelting furnace. The whole surface was in fearful agitation. Great rollers followed each other to the side, and, breaking, disclosed deep edges of crimson. These were the canals of fire we had noticed the night before diverging from a common centre, ...

... Custodio's journey was not in vain, for in addition to selling the goods at a fancy price, he would, on the way back, drive his cart in the direction of a pitch factory of the vicinity, and there he picked up from the ground a very fine coal that burned excellently and gave as much heat as slag. ...

Surely the awe-struck voyager may be excused if, at first, he refuses to believe the geologist, who tells him that these glorious masses are, after all, the hardened mud of primeval seas, or the cooled slag of subterranean furnaces—of one substance with the dullest clay, but raised by inward forces to that place of proud and ...

... itself—to make a business of an art is to degrade it. Literature should be the spontaneous output of the mind that has known and felt. To work the mine of spirit as a business and sift its product for hire, is to overwork the vein and palm off slag for sterling metal. Shakespeare was a theater-manager, Milton a secretary, Bobby Burns a farmer, Lamb a bookkeeper, Wordsworth a government employee, Emerson a lecturer, Hawthorne a custom-house inspector, and Whitman a clerk. William Morris ...

... a stiff-necked world with whitish high lights and inky shadows. These bright harsh days of barometric high pressure in England rouse and thwart every expectation of the happiness of spring. And as the bishop drove through the afternoon in a hired fly along a rutted road of slag between fields that were bitterly wired against the Sunday trespasser, he fell into a despondent meditation upon the political and ...

... keep it for sniping purposes. Hence the air was soon clouded with shells, shrapnel, and all other deadly diseases. Seeing the children had got over their shyness in this little fright and had really played quite a good game, this particular slag heap was bearing abundant fruit in the way of trophies. Furthermore, Tommy suggested that it would be indeed nice if we could make our way there one evening and collect a few German helmets, bayonets, and other curiosities for the old people ...

... Oh, Yellow-hair, I mind the first day I ever saw Scotland. 'Twas across Princess Street—across acres of Madonna lilies in that lovely foreland behind which the Rock lifted skyward with Edinburgh Castle atop made out of grey silver slag! It was a brave sight, Yellow-hair. I never loved America more than at that moment when, in my heart, I ...

Behind them their view was cut off by similar hills, black and fantastic, like the slag-heaps at the shaft of a mine. A silence fell upon the little company, and even Sadie's bright face reflected the harshness of Nature. The escort had closed in, and marched beside them, their boots scrunching among ...

... machinery was mixt up with the roar of waters, and with the various noises from the pounding and smelting-houses. The smoke of the coals however, the steam from the pits, and the black heaps of dross and slag piled up on high all around, gave the gloomy sequestered valley a still more dismal appearance; so that no one who travelled for the sake of seeking out and enjoying the beauties of nature, would have ...

... a day and locality of violent impulse and sudden action. Happenings such as these were not infrequent in a town like Hannibal. And there were events connected with slavery. Sam once saw a slave struck down and killed with a piece of slag, for a trifling offense. He saw an Abolitionist attacked by a mob that would have lynched him had not a Methodist minister defended him on a plea that he must be crazy. He did not remember in later years that he had ever seen a slave auction, ...

There was a heap of discarded ore where Grantline had carted and dumped it after his first crude refining process had yielded it as waste. The ore-slag lay like gray powder-flakes strewn down the cliff. Tracks and ore-carts along the ledge stood discarded, mute evidence of the weeks and months of work these helmeted miners had undergone, struggling upon this airless, ...

The fire in the office fireplace, kept bright until nearly midnight, when his housekeeper had given up waiting for him and gone to bed, had burned to a few smouldering lumps of cannel-slag. A big leather easy-chair, its arms worn with much use, had been pulled into an inviting position before the fireplace, and the night-light by the desk was burning, as usual. All that could be expected had been done by the kind-hearted Cynthia, who comprehended, ...

The only thing to be said in favour of this industrial scrap-heap was that ...

... hard stony substance. Indeed at first sight the pit looks like a hole dug in solid rock. In it is placed iron stone and wood charcoal which is lighted and a blast made by several pairs of bellows formed of antelope skins. The molten metal is not run off but remains with the slag in the pit until it is cool when the latter is chipped away and the shapeless mass of iron is ready to be worked into spears and lances by the blacksmiths. Probably this method is a very ancient one indeed, and it is curious that it should resemble so closely the modern ...

He has at times the primal gift of the poet—ecstasy; but to attain it he often wades through shallow, ill-smelling sewers, scales arid hills, traverses dull drab levels where the slag covers rich ore, or plunges into subterrene pools of nocturnal abominations—veritable regions of the "mother of dead dogs." Probably the sexlessness of Emerson's, Poe's, and Hawthorne's writings sent Whitman to an orgiastic extreme, and the ...

Ordinary floors may be rendered heat-proof by partially filling the space between ceiling and floorboards with sawdust or sheets of slag-wool laid on boarding nailed to fillets on the joists.

The basic-slag should be obtained direct from the iron-foundry. That kept by the chemist is not always fresh. Add one chive, one cardamon, two cloves, half a nutmeg and salt to taste.

A modern man in the same predicament would probably not think of religion at all, at any rate in the earlier stages; he would say it was a case for deeper ploughing or for basic slag. Later on, if disaster followed disaster till he began to feel himself a marked man, even the average modern would, I think, begin instinctively to reflect upon his sins. A third characteristic flows from the first. The uncharted region surrounds us on every side and is apparently infinite; ...
