This apparatus, which is simple in its operation, and not very costly, is being employed with success for irrigating several meadows in the upper basin of the Allier. Le Genie Civil. Lead oxide melted or incompletely vitrified is still in common use in the manufacture of inferior earthenware, and sometimes leads to serious results.
We must cursorily refer to some other fortifications which really scarcely belong to our subject, though certain archaeologists claim for them a prehistoric origin. We refer to the vitrified forts, which are strange structures in which stones, such as granite and gneiss, quartzite and basalt, have been subjected to a heat so intense as to produce vitrification.
They carried on a considerable trade in it with the neighbouring islands; and from the consumption thus occasioned, and the quantity of obsidian which must have been broken in the course of manufacture, we may presume that this mineral has become scarce from the lapse of ages. We are surprised to see an Atlantic nation substituting, like the natives of America, vitrified lava for iron.
You take my word for it, the best way is to leave 'em alone. Don't dandle 'em. It's hard to keep your hands off 'em, but it's right." "I'm sure of it," said Honora, who was very red. They made a strange contrast as they stood on that new street, with its new vitrified brick paving and white stone curbs, and new little trees set out in front of new little houses: Mrs.
“The liquid and red-hot matter bubbled up violently, with a hissing and crackling noise, like that which attends the playing off of an artificial firework; and by the continued splashing up of the vitrified matter, a kind of arch, or dome, was formed over the crevice from whence the lava issued; it was cracked in many parts, and appeared red-hot within, like a heated oven.
Now they were round boulders raised one above another, apparently susceptible to every breath of wind; anon, they towered like blunt-pointed obelisks, taller than the tallest trees; again they assumed the shape of mighty waves, vitrified; here, they were a small heap of fractured and riven rock; there, they rose to the grandeur of hills.
Other walls stood around, vitrified by fire the remnants of an older castle still, about which Jamblichus might have spied the lingering phantoms of many a terrible deed. They entered by the door in the great tower, under the spiky remnants of the spiral stair projecting from the huge circular wall.
Viewing this island in a chart, it would be thought an atoll; but the foregoing description shows that there is something different in its nature; Dr. Allan also states that it is cavernous, and that the coral-rock has a vitrified appearance. Is it an upheaved atoll, or the crater of a volcano? uncoloured.
That glossy, coal-black, shining lava, which is never porous, can be found only at Hekla and in its immediate vicinity; but the other varieties, jagged, porous, and vitrified, are also met with, though they are invariably black, as is the sand which covers the side of the mountain. As the distance from the volcano increases, the lava loses its jet-black colour, and fades into an iron-gray.
After a while, with a pair of long amber-colored needles, she fell to knitting with a fast, even furious ambidexterity, her mouth pursing up with a driving intensity, her boring gaze so concentrated on the thing in hand that her eyes seemed to cross. Dawn broke upon her there, her hat still cockily awry, tears dried in a vitrified gleaming down her cheeks.
