Calc spar will break up a ray of light into two parts if the light be sent through it in certain directions, but not if in another. Tourmaline polarizes light sent through its sides and becomes positively electrified at one end while being heated. Some substances will conduct sound or light or heat or electricity better in one direction than in another.
Let us take, as an example, the crystal of tourmaline, with which we are now so familiar. Let a vibration cross this crystal oblique to its axis. Experiment has assured us that a portion of the light will pass through. The quantity which passes we determine in this way.
If don't come due till after you're dead, an' then you can't get much fun out o' it." "I did not choose to be the Queen," answered Tourmaline simply. "A misfortune of birth placed me here, and I cannot escape my fate. It is much more desirable to be a private citizen, happy and carefree. But we have talked long enough of myself. Tell me who you are, and why you have come here."
There was nothin' doin' with my crowd regiment I mean and so I came here to look for "copy." That was why I persisted in seeing you home here. It was all just a matter of "copy" to me at the start. I paused, and Margot turned her tourmaline eyes full on me. Had you asked me after my first visit to old Ombos what Margot's eyes were like I could not have told you the colour to save my life.
"It is a certain win!" said Sydney. "No question about it." And a win it was, such as any old campaigner might have been proud of. At the last election Tourmaline had had a majority of six hundred over his Conservative opponent, so that there had been a turnover of about four hundred voters.
The grouping of the molecules, and of the ether associated with the molecules, reduces all the vibrations incident upon the crystal to these two directions. One of these beams, namely, that whose vibrations are perpendicular to the axis, is quenched with exceeding rapidity by the tourmaline.
At Neuera-ellia it is a favourite amusement for picnic parties to go out gem-hunting, and frequently they meet with very large and valuable stones by the riverside or near deserted pits, large garnets, cinnamon-stone, splendid cat's-eyes, amethysts, matura diamonds, moonstone, aquamarine, tourmaline rubies, and sapphires.
A path of it lay along the veranda opal and tourmaline and pearl, sharply turned aside by the shadow of the rose. Madame drew her breath quickly. There they stood, partly in the dusk and partly in the light, close in each other's arms, with the misty silver lying lovingly upon Edith's hair. She sank back into a chair, remembering, with vague terror, the vision she had seen in the crystal ball.
She did not seem very old, for her features were smiling and attractive and pleasant to view. She held in her hand a slender staff tipped with a lustrous pink jewel. All the Pinkies present bowed very respectfully to Rosalie, who returned the salutation with a dignified nod. Then Tourmaline began to explain the presence of the three strangers and the difficulty of deciding what to do with them.
But the tide runs out through the gates of sunset, And the living fires of Atlantis glow Between the clouds and the long sea-level, Beyond the waters we used to know. Hy-Brasail gleams with its towers of beryl, Tourmaline, hyacinth, topaz and pearl, Free to the King if he have but the pass-word, Free to the veriest low-born churl.
