Such moraines often repose on an older stratified alluvium, made up of rounded and worn pebbles of precisely the same rocks as those forming the moraines, but not derived from them, being small in size, never angular, polished, or striated, and the whole having evidently come from a great distance.
Professor Ramsay refers the angular form and large size of the fragments composing these breccias to the action of floating ice in the sea. These masses of angular rock, some of them weighing more than half a ton, and lying confusedly in a red, unstratified marl, like stones in boulder-drift, are in some cases polished, striated, and furrowed like erratic blocks in the moraine of a glacier.
A muscle originating on one bone and terminating on another either moves both bones toward each other or, if one attachment is fixed, the movable is drawn toward the fixed part. We may class muscles as striated or voluntary and unstriated or involuntary. A third class, mixed, is represented by the heart muscle.
For three miles or more it spreads out between striated cliffs where hawks and eagles make their nests; then once more it closes in, the creek plunges down a narrow gorge and disappears, writhing tortuously on its way to the Salagua whose fire-blasted walls rise in huge bulwarks against the south, dwarfing the near-by cliffs into nothingness by their majestic height.
A haul made on the 26th brought a prize for the geologist in the form of a lump of sandstone weighing 75 lbs., a piece of fossiliferous limestone, a fragment of striated shale, sandstone-grit, and some pebbles. Hauling in the dredge by hand was severe work, and on the 24th we used the Girling tractor-motor, which brought in 500 fathoms of line in thirty minutes, including stops.
One boulder in particular had had its origin in a valley where rounded fragments of water-washed greenstone had been poured out by the torrents and frozen into the coast-ice of the belt. The attrition of subsequent matter had truncated the great egg-shaped rock, and worn its sides into a striated face, whose scratches still indicated the line of water-flow."
The sastrugi all across the strait have been across, the main S. by E. and the other E.S.E., but these are a great study here; the hard snow is striated with long wavy lines crossed with lighter wavy lines. It gives a sort of herringbone effect. After depositing this extra load we proceeded up the Ferrar Glacier; curious low ice foot on left, no tide crack, sea ice very thinly covered with snow.
They were entering the shade of evergreens that bordered the ravine road, where there were striated cliffs, and little runnels came trickling down to join the stream below. "I guess there ain't a spot round here that means more to folks in our neighborhood than this," said Marietta.
Wonderingly, I took the bottle; dipped it down into the Pool. The liquid was extraordinarily light; seemed, in fact, to give the vial buoyancy. I held it to the light. It was striated, streaked, as though little living, pulsing veins ran through it. And its blueness, even in the vial, held an intensity of luminousness. "Radioactive," said Marakinoff.
Every untrained automatism must be domesticated, and every striated muscle capable of direct muscular control must be dominated by volition. Thus tensions and incipient contractures that drain off energy can be relaxed by fiat.
