Darian and Jonny were cracks in her armor.
Light strobed through cracks in the boards, and the sidewalks teemed with shady-looking characters dressed all in black.
You're saying there are fifty cracks in the Lake of Souls?
As a consequence of this horizontal bending of the dam the vertical cracks shown in fig.
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 larch remains free from parasitism so long as its covering is intact, but as soon as this is punctured by insects, or its continuity interfered with by cracks or fissures, the Peziza penetrates, and before long brings about the destruction of the branch.
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.
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.
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.
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.
Any cracks were thus, no doubt, temporarily closed; and as the structure of the rest of the dam was porous, no opportunity was given for the percolating water to accumulate in the horizontal fissures to anything like the head in the reservoir.
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.
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.
