Wyant was turning away with a gesture of thanks, when the other added: "If you would have the kindness to ring twice." "To ring twice?" "At the doctor's." The young man smiled. "It is the custom." It was a dazzling March afternoon, with a shower of sun from the mid-blue, and a marshalling of slaty clouds behind the umber-colored hills.

The staining is of a dull red or slaty blue colour. It must be distinguished from ecchymosis the result of a bruise, by making an incision into the part; in the case of hypostasis a few small bloody points of divided arteries will be seen, in the case of ecchymosis the subcutaneous tissues are infiltrated with blood-clot.

Between these headlands and the village there is a strip of sandhill grown over with sea-holly, and a low beach where scores of red bullocks lie close to the sea, or wade in above their knees. Further on one passes peculiar horseshoe coves, with contorted lines of sandstone on one side and slaty blue rocks on the other, and necks of transparent sea of wonderful blueness between them.

There were a few charming clumps, half-way up a slaty cliff, which it did not seem possible to scale, and she was standing at the base, looking up in vain longing, when a voice, almost at her ear, said: "Which ones do you want?" Afterwards, she wondered that she did not start at the voice.

This cleavage is known as slaty cleavage, since it is most perfectly developed in fine-grained, homogeneous rocks, such as slates, which cleave to the thin, smooth-surfaced plates with which we are familiar in the slates used in roofing and for ciphering and blackboards. In coarse-grained rocks, pressure develops more distant partings which separate the rocks into blocks.

"That's all right," he said to himself, as he began to crawl up the slope towards the ridge; and in doing so he found that flat, rough, slaty pieces of stone followed at intervals to weight the roof, and formed supports for his feet, so that he was able to creep with the greatest ease right up to the ridge.

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. This formation was frequently traversed by dykes of grey limestone of a very hard texture.

At seven miles came close to a high hill ascended it; at the foot it is composed of a hard slaty stone covered with a cake of iron; about the middle is quartz, and on the top conglomerated quartz. The view from south-west to north-west is extensive, but this not being the highest hill, the rest is hidden.

The chief obstacle would be the early and complete loss of the pale-blue tint, from the necessity of reiterated crosses with the slaty female, the latter not having at first any LATENT tendency to produce pale-blue offspring.

It is not uncommon to meet with an argillaceous rock having the same composition, without the slaty cleavage, which may be called argillite. CHLORITE SCHIST is a green slaty rock, in which chlorite is abundant in foliated plates, usually blended with minute grains of quartz, or sometimes with feldspar or mica; often associated with, and graduating into, gneiss and clay- slate.
