Garnets are often found imbedded in the laminae, flattened by the extreme pressure to which the mass was subjected. It is fascinating material, this mica, to handle, and we amused ourselves by experimenting on the thinness to which its scales could be reduced by splitting.
But she interrupted with such a "Mica!" that I did not venture on another word. "What did she say?" Paul asked. "She said she thought you were charming." But he was in no humor for joking, and begged me dryly not to make fun of him; so I translated her question and my polite offer, which had been so rudely rejected. Then he really became as restless as a caged squirrel.
Nearly all were bare-headed, and nearly all wore aigrettes; a score of these, a hundred of them, nodded and vibrated with an incessant agitation over the heads of the crowd and flashed like mica flakes as the wearers moved.
The gneiss did not act upon the magnetic needle; yet along the coast, which forms a cove near Cape Codera, and which is covered with a fine forest, I saw magnetic sand mixed with spangles of mica, deposited by the sea. This phenomenon occurs again near the port of La Guayra.
All the rest of the forest was silent. Not a breath of wind stirred the tallest fir-tip or swayed the most lofty pine branch. Through the woodland spaces the sunlight sparkled with the inconceivable brilliance of the higher levels, as though the air were filled with glittering particles in suspension, like the mica snowstorms of the peep shows inside a child's candy egg.
All are even grained, consisting of a mass of crystalline grains formed during one continuous stage of solidification, and no porphyritic crystals appear as in lavas. GRANITE, as we have learned already, is composed of three minerals, quartz, feldspar, and mica. According to the color of the feldspar the rock may be red, or pink, or gray.
The mill consists of a block of granite, syenite, or even mica schist, fifteen or eighteen inches square and five or six thick, with a piece of quartz or other hard rock about the size of a half brick, one side of which has a convex surface, and fits into a concave hollow in the larger and stationary stone.
Mica schist crowned some of the heights on the watershed, then gneiss, and now, as we descend further, we have igneous rocks of more recent eruption, porphyry and gneiss, with hornblende.
With an occasional lounge on the soft sand, when the body became clad in a costume of mica spangles and finely comminuted shell grit, the bathe continued for two hours, with an after effect of sleek and silky content.
Meeting that desperate man with a rope instead of a gun!" "You didn't know I was going to meet him with a rope," he said. He stood before her, hat in hand, wholesomely honest in his homely ruggedness, a flush of embarrassment tinging his face. The sun in his short hair seemed laughing, picking out little flecks of gold as mica flakes in the sea waves turn and flash. "You might have been killed!
