The ascent of the hills, which are densely wooded, was along spurs, and over knolls of clay; the rocks were sandy and slaty ?
In one place the latter rock is seen bursting through the gneiss, which is slaty and very crystalline at the junction.
Below lay the dull reds and slaty grays of the houses, concealed here and there by the massive foliage of the trees that lined the river bank.
All about were beautiful gorges between which the river rushed noisily, now following the base of a precipice of solid limestone, and again laving the roots of large trees growing luxuriantly on the slaty banks.
Her eyes were slaty blue and there was a delicate suggestion--almost an apparition--of grey in her hair.
All the hills in this district were of a slaty formation with thin veins of white quartz.
As we drew nearer we could see the notable Session Stone, a broad flat stone overhanging the little pourie burn that tinkles and lingers among the slaty rocks, now shining bone-white in the glare of the autumn sun.
All this coast is slaty shale; there is a miniature quarry just away to the west round the next headland, and the materials lying to hand were not likely to be neglected in days when transport was more of a consideration than now.
The caterpillar is slaty grey inclining to purplish, with a series of not clearly defined ochreous diamonds on the back and a row of ochreous dots on each side; the raised points on the last ring are tipped with reddish (Plate 116).
The typical form of this species has the fore wings of a pale slatygrey colour; this, however, does not seem to occur in Britain.
Stephens in 1831 referred the smoky or dark slaty grey form (Fig.
I replied that I could, and followed Gunson, who showed me the way he had descended by the help of the rocks, and projecting roots of the dwarf firs which began to grow freely as soon as the slaty shale ceased.
This however was somewhat larger than those, and though steep-sided as they were it did not disclose the same white strata of chalk and gypsum, its formation being more rocky and of rather a slaty character.
Like all the others I had recently examined, it was composed principally of quartz, ironstone and a kind of slaty rock; the low hills in front exhibiting the grey limestone, whilst patches of gum scrub were observable in many places.
In the lower or front hills the rock was argillaceous, of a hard slaty nature, and inclined at an angle of about 45 degrees from the horizontal.
He turned to findSlaty himself chuckling merrily as he picked up seeds.
Slaty the Junco had been quite right in thinking it was going to snow some more.
Just then Dotty, who had been picking seeds out of the top of a weed, gave a cry of alarm and instantly there was a flit of many wings as Dotty and his relatives and Slaty sought the shelter of the bushes along the edge of the field.
He started first for the weedy field where the day before he had found Dotty the Tree Sparrow and Slaty the Junco.
There was no mistaking Slaty the Junco for any other bird.
Slaty the Junco and his relatives came along with us and we had a very merry party.
Upper wing surface blackish brown with a slaty tinge, and red spots at base of the single short tail on each hind wing.
Under surface slaty brown with prominent silver crescents on the hind wings.
I knew it only by its slaty shimmer through the fading green of the tree-tops between me and it.
The Lower Llandovery rocks consist of conglomerates, sandstones andslaty beds.
Bits here and there are not unlike the 'chimneys' on Slieve League, but the material is more friable, resembling loose walls of very inferior slaty fragments.
But in four or five places odd right-angled walls of horizontal, loosely-balanced blocks of slatyschist jut out right across the face of the cliff, the legs of the angle being sheer to the sea and horizontal above.
It is entirely composed of a slaty rock, traversed by numerous veins of Actinolite.
The rock is composed of well marked Greenstone, resting on a bed of clay-slate, and which, in its direction and dip, will be found to correspond with the slaty rock on the western base of the Mount.
The ironstone either occurs in concretionary nodules, often formed around some organic nucleus, or it is an argillaceous ore, having a slaty structure.
A great deal of chemical action then commences; salts of various kinds effloresce on the surface, and the mass becomes hard, and divides into fragments which possess an even and well-defined slaty structure.
The last rock of this series is a slaty rock, more or less highly argillaceous.
The usual view entertained as to what is called slaty structure is, that it depends on pressure, acting on more or less compressible material in some direction usually different from that of the bedding.
They have often assumed a slaty structure, and their bedding, and the fossils which they contain, are both affected by this.
The Trilobites lived on muddy bottoms, and their remains are extremely abundant in shaly and slaty beds, though found also in limestone and sandstone.
Slaty cleavage and distortion are not, however, confined to Primordial rocks, but occur in altered sediments of various ages.
In colour it is dark brown, somewhat slaty in summer; the chin, inside of limbs and tail, and a patch on the buttocks yellowish or orange yellow.
Body pisciform, terminated by a horizontal fin with two lobes; colour slaty brown above, sometimes bluish black, whitish below.
General hue olive brown, each hair having a blackish tip, a sub-apical yellow band, and a slatyblack base.
Indicus; the hairs of the upper parts have no black tips, and the basal two-thirds are slaty grey.
In that country, also, the sameslaty material was used, sometimes green, and sometimes red in colour.
It is formed of a hard slaty stone, having one side ground to a regularly curved and sharp edge, and the others rounded by grinding.
Sword-like blades made of slaty stone are also found in Ireland[1592] and in Shetland.
Though not formed of flint, but of a hard slaty rock of the nature of hone-stone, an implement of much the same form as that from Fimber[1550] may be here described.
It is formed of a hard, green, slaty rock, and was found in Burwell Fen.
Two pieces of a dark-coloured slaty kind of stone, of nearly the same form and size as the Yorkshire specimen, and lying parallel with each other, were found by Sir R.
One of grey slaty stone with a countersunk hole at each end accompanied an interment at Sittingbourne,[2042] Kent, and is now in the British Museum.
They are usually of sandstone, and not formed from slaty rocks.
I have several such, found with whorls ofslaty stone in Cambridgeshire.
The rock is a darkslaty looking tufa, the surface of which displays ring or rosette-like markings, reminding one of the polished surface of a section of fossil coral.
Another class of objects made of the same fine grained, slaty looking tufa is illustrated in Fig.
