Hot stone

“ A babel of broken conversation, questions and replies, jests and laughter, drowned the cries of the dealers, and a strong, penetrating odour of human sweat rose on the hot air. From time to time a block occurred, and the crowd stood motionless, waiting patiently until they could move ahead. In one of these sudden blocks Chook, who was craning his neck to watch the vegetable stalls, felt someone pushing, and turning his head, found himself staring into the eyes of Pinkey, the red-haired. ”

“ The pile of white linen brought into relief the dirt and poverty of the interior. The walls were stained with grease and patches of dirt, added slowly through the years as a face gathers wrinkles. But Jonah saw nothing of this. He was used to dirt.
He sat down, and, with a sudden attack of politeness, decided to take off his hat, but, uncertain of his footing, pushed it on the back of his head as a compromise. He lit a cigarette, and felt more at ease.
A faint odour of scorching reached his nostrils as Mrs Yabsley passed the hot iron over the white fronts. ”

“ There will still be the question why Tuscany, although it abounds in hot springs, does not furnish a powder out of which, on the same principle, a wall can be made which will set fast under water. I have therefore thought best to explain how this seems to be, before the question should be raised.
5. The same kinds of soil are not found in all places and countries alike, nor is stone found everywhere. Some soils are earthy; others gravelly, and again pebbly; in other places the material is sandy; in a word, the properties of the soil are as different and unlike as are the various countries. ”

“ Other stones, such as ‘fired’ zircon, white sapphire, white topaz, and rock-crystal, may dazzle with brilliancy of light reflected from the surface or emitted from the interior, but none of them, like diamond, glow with mysterious gleams. No hint of colour, save perhaps a trace of the blue of steel, can be tolerated in stones of this category; above all is a touch of the jaundice hue of yellow abhorred. It taxes all the skill of the lapidary to assure that the disposition of the facets be such as to reveal the full splendour of the stone. ”

“ But if the stone is first thrown into the kiln, it loses its former property of solidity by exposure to the great heat of the fire, and so with its strength burnt out and exhausted it is left with its pores open and empty. Hence, the moisture and air in the body of the stone being burned out and set free, and only a residuum of heat being left lying in it, if the stone is then immersed in water, the moisture, before the water can feel the influence of the fire, makes its way into the open pores ”

“ Composed of deep brown granite, with here and there immense veins, or patches many miles in extent, of jet-black, shining ironstone, they absorb the torrid sunshine all day, becoming almost red-hot in the process. At night this heat is radiated rapidly at high sunlight power, until the furnace of midnight becomes like an ice-house at dawn. ”

“ Even if you have never learnt much of what is called geology, by keeping your eyes open and your mind awake you may see a great deal in the stones which have perhaps seemed to you most uninteresting. A block of granite from one of the Dartmoor hills, and a piece of slate from a Welsh quarry—how different these two kinds of stone are! We see this at once; but they become much more interesting when we know that each has its own history. ”

“ Not so; at least to any one who knows the look of a hard stone. You may, by rustication, make your good marble or granite look like wet slime, honeycombed by sand-eels, or like half-baked tufo covered with slow exudation of stalactite, or like rotten claystone coated with concretions of its own mud; but not like the stones of which the hard world is built. Do not think that nature rusticates her foundations. ”

“ The clay outside of the stones bears evidence of intense heat. In some instances they are nearly filled with ashes and charcoal. The pottery within them is composed of shell and clay. At a higher level, the fireplaces, while not so numerous, are more interesting, because more or less of fire relics are obtained from them. They are only slightly concave, and mixed with the ashes are stones broken by the action of fire, bones of various kinds, arrow-heads, drills, stone and hematite celts, stone pipes, perforated stones called shuttles, and much broken pottery. ”

“ This is because in its natural composition there is but little moisture and not much of the earthy, but a great deal of air and of fire. Therefore, it is not only without the earthy and watery elements, but when fire, expelling the air from it by the operation and force of heat, penetrates into its inmost parts and occupies the empty spaces of the [50] fissures, there comes a great glow and the stone is made to burn as fiercely as do the particles of fire itself. ”

“ But it is formed, as you all know, in the earth, not as a metal, but as a stone, as chalk or limestone, which is a carbonate of lime; that is, calcium combined with oxygen and carbonic-acid gases.
In that state it will make, if it is crystalline and hard, excellent building stone. The finest white marble, like that of Carrara in Italy, of which the most delicate statues are carved, is carbonate of lime altered and hardened by volcanic heat. But to make mortar of it, it must be softened and then brought into a state in which it can be hardened again ”

“ Most of the Stones of this Class were found to be of so compact a Texture, as to resist the Force of Fire; at least of common Fires; and even of the strongest known in this Author's Time; the solar indeed, which we are able to throw on Bodies, by reflecting Burning-glasses, no Stone, not even the Diamond, in all Circumstances and Positions, can withstand: But as some Stones, which he had yet to treat of, were subject to great Changes, from the Action of Fire, such as was then commonly used on certain occasions, whether culinary, or for the melting of Metals ”

“ This precious stone, as durable as the sun, and far more accessible than that, shines with the same fire, unites all its rays and colours in a single facet, and lavishes its charms, by night and day, in every clime, at all seasons; whilst the sun appears only when it so pleases; sometimes shining, sometimes misty, and shows itself off with innumerable pretensions. ”

“ A close-grained stone called lithographic stone (a kind of magnesian limestone) is ground perfectly even on the surface, and (if for being written upon) polished with pumice-stone, or (if for being drawn upon with chalk) grained with fine sand; the design is drawn with chalk or ink, each of which is made up of greasy materials—wax, soap, and asphaltum, colored with lamp-black. When the design is made, the stone is etched—washed over with a weak mixture of nitric acid and water—which answers three purposes ”

“ All these modern stones appear to be hard and solid when they are first hewn out, but when, exposed to the weather, the air and rain presently dissolve them; their substance is so different from true stone, that when reduced into minute parts, to make sand of them, they are converted into a kind of earth or clay. ”

“ Thus the water is thrown off by the operation of the centrifugal force, and two tons of clay can be dried in five minutes.
The remarkable contrast between the extreme hardness and softness of the same primitive rock is a curiosity of geology well worth notice. ‘A stone,’ says the author of ‘Cornwall and its Mines,’ ‘is primevally fused and cooled into as hard a substance as nature affords; so hard that it paves our streets in long enduring slabs and blocks. Tens of thousands of feet passing daily over it make no impression upon it. Years of travel only see it smooth and shining. ”

“ The rock here is a sort of sand or pudding stone; there is no limestone or granite. And all the hills are tree-covered. To many this clothing of verdure is most restful and pleasing. I missed the sharp outlines, the delicate artistic sky lines, sharply defined in uplifted bare granite peaks and ridges, with the purple and violet color of the northern mountains, and which it seems to me that limestone and granite formations give. There are none of the great gorges and awful abysses of the White Mountains, both valleys and mountains here being more uniform in outline. ”

“ The place where the lower or 12 inch course is above the Rock, should be made up with stone of the same quality as the Rock itself. These stones should be dove-tailed into the rock, and laid with pozzolano mortar, secured by the Roman cement, the same as the other; for if done with harder stone (should the [468] rock waste at all) it would resist the waves better than the soft, and occasion a more speedy waste of the other parts of the Rock than the Tower. ”

“ That manufactured objects of stone and iron have fallen from the sky:
That they have been brought down from a state of suspension, in a region of inertness to this earth's attraction, by atmospheric disturbances.
The "thunderstone" is usually "a beautifully polished, wedge-shaped piece of greenstone," says a writer in the Cornhill Magazine, 50-517. It isn't: it's likely to be of almost any kind of stone, but we call attention to the skill with which some of them have been made. ”

“ After a little they turned off toward a tremendous rock of solid granite that had been cleft smoothly in twain by some gigantic force of nature, and, walking between the towering walls of stone, came out on the farther side upon a small level space, where immense ferns and flags grew thickly in the rich soil, held in place and kept damp by the great cool masses of stone. ”

“ A stone is merely a stone to most men. But within the interstices of the stone, and involving it like an atmosphere, are great and mighty influences, powers which are fearful in their grander operations, and wonderful in their gentler developments. The stone and the flower hold, locked up in their recesses, the three great known forces—light, heat, and electricity: and, in all probability, others of a more exalted nature still, to which these powers are but subordinate agents. ”

“ The united and increasing action of the winds and waves has worn the hard granite rock into the most fantastic forms, and from certain points of view it is not difficult to invest some of these masses of stone with a fancied resemblance to the human form. ”

“ And standing there beside a mass of crumbled granite, gray like the stone itself, his hulking body naked, neither clad nor furred, incredibly long arms now swinging as his weak eyes focused under bone-ridged brows, a man—though not a man—was raising in his ugly hand a shining tubelike object. ”

“ The four native stones among the five gems are usually translucent, while most of the other stones are opaque. A transparent or translucent stone, if it is cut as a prism or if its crystalline structure is right, may break light into rainbow hues, and, catching these rays, may shoot them around in varying interplays of sparkle and color. The opaque stones, on the other hand, often smooth of surface, are colored in ways that seem to snare the light and send it out with added power and color. ”

“ All over the face of the hill there are masses of this hard pebbly sandstone cropping up, though they are not so noticeable as the so-called Devil's Stone because they are flat and occasionally crumbling, and have not had their sides laid bare by energetic treasure-seekers. ”

“ And yet we do not assume that the whole interior of this globe of ours is composed of stones or iron (although Franciscus Maurolycus, that learned man, deems the whole of the earth's interior to consist of solid stone) . For not every loadstone that we have is a stone, it being sometimes like a clod, or like clay and iron either firmly compacted together out of various materials, or of a softer composition, or by heat reduced to the metallick state ”

“ Material: black slate and granite. Phillips Academy collection, Andover. The one to the right has a groove about the top. There are many of these in all museum collections, and I am sorry I cannot illustrate a large number of them. They range from the ordinary ridged form, unperforated, to long, slender, almost pick-shaped objects. They constitute a study in themselves. There have been many theories as to drilled and winged objects, but these pendant-shaped, “coffin”-shaped, and kindred stones not only defy classification, but there is absolutely no use to be assigned them. ”

“ In all countries the fundamental rock on which the boulder formation reposes, if it consists of granite, gneiss, marble, or other hard stone capable of permanently retaining any superficial markings which may have been imprinted upon it, is smoothed or polished, and exhibits parallel striae and furrows having a determinate direction. ”

“ Fire-Stone, or Soap Stone, serves chiefly for chimneys, hearths, ovens, furnaces, and stoves; being a dry, porous, gritty stone, which bears the heat without breaking: on account of this quality, it is called fire-stone. ”

“ It may, I think, be safely said that—although nature furnishes numerous examples, in many classes of rocks, and especially in flints, of stones perforated with holes, and although they appear to have attracted the notice of the aborigines of many countries by the peculiar superstitious reverence which is often found to be attached to such stones when found in the soil—this mode of fastening stone implements in their handles did not come into use until late in the stone age, and that even in the bronze age it was but little employed. ”
