Darian and Jonny were cracks in her armor.
As a consequence of this horizontal bending of the dam the vertical cracks shown in fig.
You're saying there are fifty cracks in the Lake of Souls?
Light strobed through cracks in the boards, and the sidewalks teemed with shady-looking characters dressed all in black.
Westlake plugged forward, his nose nearly at the windshield, which was spider-webbed with nicks and cracks, as the old car crawled higher.
As the sun climbed over the mountains, it spread its glow across the snow still nestled in the cracks and crevices above him.
The winter wind has come a-calling and moans through cracks and crevices like so many ghosts visiting from hell, wailing and beckoning for me to join them.
The frigid air would simply sneak under the house and ooze up through the cracks in the floor.
Further, the skin is stated to be much less rough, with fewer cracks, while a more important difference occurs in the trunk, which lacks the transverse ridges so distinctive of the ordinary African elephant, and thereby approximates to the Asiatic species.
The nodules are penetrated by cracks,;but the material can be worked on the lathe.
The root is made to press its way into the darker cracks and crannies of the soil, so bringing its root-hairs into better contact with the particles round which the hygroscopic water hangs.
Frost-cracks, scorching of bark by sun and fire, &c., anc wounds due to plants which entwine, pierce or otherwise materially injure trees, &c., on a large scale.
Such frost-cracks, sun-cracks, &c., may then be slowly healed over by callus, but if the conditions for necrosis recur the crack may be again opened, or if Fungi, &c., interfere with occlusion, the healing is prevented; in such cases the local necrosis may give rise to cankers.
The winter moth (Cheimatobia brumata) must be kept in check by putting greasy bands round the trunks from October till December or January, to catch the wingless females that crawl up and deposit their eggs in the cracks and crevices in the bark.
In Scandinavia a thick turpentine oozes from cracks or fissures in the bark, forming by its congelation a fine yellow resin, known commercially as "spruce rosin," or "frankincense"; it is also procured artificially by cutting off the ends of the lower branches, when it slowly exudes from the extremities.
Minute cracks are sometimes produced by the contraction; they are often more or less straight, but in other cases a very perfect system of rounded fissures arises.
There may be concentric series of cracks one within another.
Occasionally the rounded cracks extend from the matrix into some of the crystals especially those of quartz which have naturally a conchoidal fracture.
Many vitreous rocks show alteration of this type in certain parts where either the glass has been of unstable nature or where agencies of change such as percolating water have had easiest access (as along joints, perlitic cracks and the margins of dikes and sills).
A similar six-rayed system of cracks, bisecting the angles between the rays of the previous set, is produced when a blunt punch is gradually pressed against a sheet of mica; this is known as the "pressure figure."
These cracks coincide with planes of easy separation or of gliding in the crystal; they are especially useful in helping to determine the crystallographic orientation of a cleavage flake of mica when crystal faces are absent.
And free from cracks and flaws have frequently been obtained.
It must be used with extreme care, and in small quantities, and it must not be used at all where cuts or cracks are present in the skin.
The action of frost is also very destructive to many stones, since the water within their cracks and crannies expands on freezing and splits off small pieces from their surfaces.
A ripe leaf easily cracks or shows a crease when folded between the fingers.
The spores germinate on a damp surface and enter the cortex through small cracks or wounds in the protecting layer.
Of Kilauea are small channels with steam cracks, along which appears the only vegetation of the region.
In order to secure tightness in spite of cracks, mercury was placed in the bends.
One of the great objections to the appearance of concrete is the fact that soon after its erection irregular cracks invariably appear on its surface.
These cracks are probably due to shrinkage while setting, aggravated by changes in temperature.
In the case of a smooth concrete face there are no joints to follow, and the cracks become an ugly feature.
They are sometimes regulated by forming artificial "joints" in the structure by embedding strips of wood or sheet iron at regular intervals, thus forming "lines of weakness," at which the cracks therefore take place.
The older houses are of brick, overlaid with white or tinted plaster, and ornamented with figures or foliage in terra-cotta; but owing to the great changes of temperature in Rumania, the plaster soon cracks and peels off, giving a dilapidated appearance to many streets.
13) should be much more effective in starting cracks under distortion than that of the far more minute particles of cementite which lie embedded, indeed drowned, in the sixfold greater mass of ferrite with which they are associated in the pearlite itself.
Immediately heals over any cracks which form in the small quantity of cementite interstratified with it in the pearlite of hypo-eutectoid steels.
Thanks to the glass-hardness of this face, the projectile is arrested so abruptly that it is shattered, and its energy is delivered piecemeal by its fragments; but as the face is integrally united with the unhardened, ductile and slightly yielding interior and back, the plate, even if it is locally bent backwards somewhat by the blow, neither cracks nor flakes.
Chalcedony occurs as a secondary mineral in volcanic rocks, representing usually the silica set free by the decomposition of various silicates, and deposited in cracks, forming veins, or in vesicular hollows, forming amygdales.
The slurry, in drying on the floor of the flue, forms a fairly tough cake which cracks spontaneously in the process of drying into rough blocks suitable for loading into the kiln.
Formerly the soundness of cement was determined by keeping thin parts of the cement in cold water for twenty-eight days, or in warm water (I 10°-120° F.) for twenty-four hours, and examining for cracks or other signs of expansion.
The structure is free to take its permanent position before the lime sets, and cracks are thus avoided.
Mahogany cement, for filling up cracks in wood, consists of 4 parts of beeswax, i of Indian red and yellowochre to give colour.
It warps and cracks rather badly, and weighs from 35 to 42 lb per cub.
In consequence the fire-gases, when arriving there by the chimney shaft (a), have already a good upward draught, and when circulatung round the muffle are at a lower pressure than the gases within the muffle, so that in case of any cracks being formed, no hydrochloric acid escapes into the fire-flues, but vice versa.
Evidences of shallow water conditions arc abundant; very frequently on the bedding surfaces of sandstones and other rocks we find cracks made by the sun's heat and pittings caused by the showers that fell from the Cambrian sky, and these records of the weather of this remote period are preserved as sharply and clearly as those made only to-day on our tidal reaches.
It is ready for gathering when the core cracks and separates easily from the fibre.
It often fills cracks and fissures in the rock.
Steel plates and shapes, when delivered from the rolls which form them to the cooling beds, are largely covered with scales, which, adhering only partially to the surface, offer the intervening cracks or joints as vulnerable points for rust.
All finished material is carefully examined to see that it possesses a smooth surface, and that it is free from cracks, seams and other defects, and that it is true to section throughout.
Among the sedimentary rocks we have, for example, in the clay slates of the Silurian formations, rocks no less cracked and fissured than others, but generally quite impermeable by reason of the joints being packed with the very fine clay resulting from the rubbing of slate upon slate in the earth movements to which the cracks are due.
Imagine for a moment that the sand grains were by any means rendered immobile without change in the permeability of their interspaces; we could then dispense with the iron or brickwork lining of the well; but as there would still be no cracks or fissures to extend the area of percolating water exposed to the open well, the yield would be very small.
In the case of the Neuadd dam this difficulty was met by deliberately omitting the mortar in transverse joints at regular intervals near the top of the dam, except just at their faces, where it of course cracks harmlessly, and by filling the rest with asphalt.
It is stated, however, that these cracks close up and become practically water-tight as the water rises.
Years after this, and about fifteen years after the dam was first brought into use, it overturned on its outer edge, at about the level indicated by the dotted line just above the counterfort; and there is no good reason to attribute to the movement of 1884, or to the vertical cracks it caused, any influence in the overturning of 1895.
Some of the worst cracks were, indeed, entirely beyond the portion overturned, which consisted of the mass 570 ft.
By reason of the constantly changing temperatures and the frequent filling and emptying of the reservoir, expansion and contraction, which are always at work tending to produce relative movements wherever one portion of a structure is weaker than another, must have assisted the water-pressure in the extension of the horizontal cracks, which, growing slowly during the fifteen years, provided at last the area required to enable the intrusive water to overbalance the little remaining stability of the dam.
Their surfaces often show minute crescentic or rounded cracks which are the edges of small conchoidal fractures produced by the impact of one pebble on another during storms or floods.
Evidently the flint has accumulated along fissures, such as bedding planes, joints and other cracks, after the chalk had to some extent consolidated.
And S.E., broke through the region now occupied by the British Isles, and basalt was pressed up along these cracks, forming thousands of dikes, from the coast of Down to the Dalradian ridges of Donegal.
Sounds of crying and screaming came from somewhere in the distance outside, and flames were visible through the cracks of the shed, but inside it was quiet and dark.
But even filters of this type, if they are to be fully relied upon, must be frequently cleaned and sterilized, and great care must be taken that the joints and connexions are watertight, and that the candles are without cracks or flaws.
