Snellen chart

“ I mean there's always potential for mis-reading of any piece of information on a chart. That's always possible, but in this case, the slash between the two of them is the same as you see in the profile there to illustrate that same kind of differentiation.
MR. BERMAN: Hm-hmm. Is -- is or has Jeppesen given any consideration to the human factors of the line breaks on the charts?
THE WITNESS: We have done a lot of work with the human factors. With the line breaks like this, we've done some, but this has not been our largest area of concentration. ”

“ But maybe Dan can help me out with the chart." [Pg 46]
"Don't depend on me," said Dan emphatically; "my arithmetic is about like yours. I know how many pecks of corn make a bushel and how many rods are in an acre, but that sort o' knowledge wouldn't be much help in cuttin' out a woman's jacket." And early the next morning Sally returned the chart, acknowledging that its mathematical complexities had baffled both herself and Dan. "And besides," she added, "I don't believe there's enough of my China silk to cut anything. ”

“ The agent looked up with a cheery smile. He had folded the chart, and was tying the red tape fastenings.
"I've got to get back to town in time to catch that four o'clock train for Shepherdsville. I'm a thousand times obliged to you, Madam, for letting me show you the working of the chart. Sometimes I have a good deal of difficulty in getting ladies to understand the modus operandi of the thing. Unless a woman remembers the arithmetic she learned when she was a schoolgirl, she is apt to have trouble taking measurements. But it's a pleasure to show any one who sees into it as readily as you do. ”

“ SNELL, WILLEBRORD (1591–1626) , commonly known as Snellius, Dutch astronomer and mathematician, was born at Leiden in 1591. In 1613 he succeeded his father Rudolph Snell (1546–1613) as professor of mathematics in the university of Leiden. In 1615 he planned and carried into practice a new method of finding the dimensions of the earth, by determining the distance of one point on its surface from the parallel of another, by means of a triangulation. ”

“ Willebrod Snellius, mathematical professor of Leyden, introduced the true method of measuring the degrees of longitude and latitude, and Huygens, who had seen his manuscripts, asserted that Snellius had invented, before Descartes, the doctrine of refraction.
But it was especially to that noble band of heroes and martyrs, the great navigators and geographical discoverers of the republic, that science is above all indebted. ”

“ Disregarding the two short stretches of sidewalk that bordered the street, Snellins stepped out into the road, facing toward the east. The light fell upon his back and cast a short shadow before him that he saw without observing, and, as it moved along with jerky motion, he tried to uproot the doubt of the parson's friendship, which grieved him sorely. Times without number a smile spread over his face only to be driven off by a doubt insubordinate to his heart's good inclinations. ”

“ Now and again he straightened up to swing a pick into the frozen gravel which lay within the circle of light made by his pocket flashlight. After a few strokes he would throw down the pick and begin breaking up the lumps. Every now and again, he would lift the small sack into which the lumps were dropped. It grew heavier every moment.
It was quite dark all about him; indeed, Johnny was nearly a hundred feet straight into the heart of a cut bank, and, to start on this straight ahead drift, he had been obliged to lower himself into a shaft as into a well, a drop of fifteen feet or more. ”

“ They awoke to a world unknown. The first glimpse outside the cabin brought surprised exclamations to their lips. The "white line" was gone. So, too, was the ocean. Before them, as far as the eye could see, lay a mass of yellow lights and purple shadows, ice-fields that had buried the sea. Only one object stood out black and bare before them—the hull of the wrecked ship.
"Look!" said Lucile, suddenly. "We can go out to the ship over the ice-floe!"
"'THE WHITE LINE!' EXCLAIMED MARION, GRIPPING HER ARM"
"Let's do it," said Marion, eagerly. ”

“ Snelling would have them even trained to work the guns, although, if it blew at all hard, not one could be got to go aloft, except their old serang and the tindal, his mate. What surprised me most was the harbour officer himself at last asking, as Mr Snelling told me, to be put in a watch; but as the midshipman said there was no doubt Webb had made a voyage or two before, somewhere or other, I agreed to it at once. ”

“ Booth threw the circle of his flash-light out to sea.
"Stop that!" cried Hugh, in alarm. "They might take a shot at us."
"Let 'em," growled Booth, now thoroughly out of humor. "What's it all about, anyway?"
"Boys, look!" cried Lucile, suddenly; "Our boat's gone!"
Hastening down the beach, they found it was all too true; the row-boat had disappeared.
"There weren't any men!" exclaimed Hugh, with sudden conviction; "That chap's taken our boat and skipped!"
"Yes, there were men," insisted Lucile. "We saw their tracks in the sand, didn't we, Marion?" ”

“ Nelsen growled into his phone.
"It has," came the mocking answer. "Be cavalier, Nelsen. Salute the new top outlaw... Don't faint— I knew I'd make it... And don't try anything you might regret... I'm coming in with a couple of my Jolly Lads. You'd better not welsh on your promises. Because the others are armed and waiting..."
The guys with Tiflin looked more tired than tough. Out from under their fierce, truculent bravado showed the fiercer hunger for common things and comforts. Nelsen knew. ”

“ Nelsen could almost hear the coarse laughter of the Jolly Lads, as they broke it up, robbed it, raped it—because they both sneered at its effeteness, and missed what it represented to them... Nelsen remembered very well how a man's attitudes could be warped while he struggled for mere survival in an Archer drifting in space.
Yet even as he worked with the others, to put up temporary domes and to gather the bloated dead, the hatred arose in him, and was strengthened by the fury and grief in the grim, strong faces around him. To exist where it was, Pallastown could not be as soft as it seemed. ”

“ Frank Nelsen crept carefully back into his own rotating ring, still half afraid that an armored knee or elbow might go right through the thin, yielding stellene. Prone, and with his helmet still sealed, he slipped into the fog which the tranquilizer now induced in his brain, while the universe of stars, Moon, sun and Earth tumbled regularly around him.
He dreamed of yelling in endless fall, and of climbing over metal-veined chunks of a broken world, where once there had been air, sea, desert and forest, and minds not unlike those of men, but in bodies that were far different. ”

“ He kicked the net contemptuously. "Tell us one thing though," he confided to Rover; "there are people on this island, or at least have been. Natives of some kind, they must be, for no white man would have the patience to make a net of sealskin as fine as that. Question is, were they just camping here to gather eggs or do they live here? If they live here, what kind of people are they? Well, anyway, let's go see."
Wearily he dragged his tired limbs up a gentle slope. Wearily the old dog followed on. ”

“ Still he did not look at the book but to her utter astonishment said, while a smile illumined his face, “I bought that copy of ‘The Compleat Angler’ right here in this alcove.”
[196]
“From whom?” she half whispered.
“From old Dan Whitner, who keeps a bookshop back on Walton place.”
“Thank you,” she murmured, much relieved. Here was no mystery; one bookshop selling a book to another. There was more to it. She must follow on.
“I suppose,” he smiled, as if reading her thoughts, “that you’d like me to tell you where Dan got it, but that I cannot answer. You must ask him yourself. ”

“ The door was really opened at that moment by a maid, and in walk Professor Snellius, Mrs. Professor Snellius, and Miss Ida Snellius.
The broken peace of the Clemens family is immediately restored. They receive the new-comers as heartily as people who have worked their way to genuine humanity are apt to welcome their friends.
Professor Snellius, teacher of the first form and con-rector, a man of some forty years, aspired, like Rector Clemens, and perhaps even more energetically, to the ideal, and was perhaps even more favored in these efforts by his outward appearance. ”

“ And as memory, when duly impregnated with ascertained facts, is sometimes surprisingly fertile, Mr Snell gradually recovered a vivid impression of the effect produced on him by the pedlar's countenance and conversation. He had a "look with his eye" which fell unpleasantly on Mr Snell's sensitive organism. To be sure, he didn't say anything particular—no, except that about the tinder-box—but it isn't what a man says, it's the way he says it. Moreover, he had a swarthy foreignness of complexion which boded little honesty.
"Did he wear ear-rings?" ”

“ And then there was the tormenting, bewitching, wretched, alluring uncertainty of it all. One could never be sure, and in the spell of this disquietude lay half the magic.
Robert Morton speculated as to whether Willie, along with Jezebel and the canary, had fathomed the idyl. He wondered, too, how much Snelling suspected. The New Yorker had an irritating habit of waylaying Delight and making pretty speeches to her, as if for the wanton pleasure of watching the blush rise in her cheek. When it came to women there was no denying Howard Snelling was as great an authority as at building ships. ”

“ Johnny’s thoughts were cut short by a hand lightly laid on his shoulder.
“Thought I’d find you here.” It was his employer. “Some things in the factory I want to show you when the men are gone. They’re about out now. I’ll just wait here. Don’t let me disturb you.”
[25]
But Johnny had been disturbed; his eyes for the moment had been drawn from that passing string of men and the electro-magnet. As he again focused his eyes on the crack, he gave an involuntary start. Clinging to the face of the electro-magnet as if glued there, was an oblong paper box—a lunch-box. And the man who owned it? ”

“ She opened her mouth to speak: then bit her lips, and remained quiet.
"What is it, Nelly?" said her father.
"Nothing, sir," replied Nelly: "only I don't think Mr. Kleesman is like that. He is very kind."
"Oh, yes, he's kind enough," said Mr. Scholfield: "he's a good-natured fellow. But it's all moonshine about his being the only one who can make assays. There's a plenty of mines working here to-day that haven't ever had any assay made except by the blow-pipe. There's no use in paying a fellow three or four or five dollars for doing what you can do yourself."
"But that man said—" began Rob. ”

“ Now and then Nelsen was in Pallastown—for business, for relief, for a bit of hell-raising; to see Gimp and the David Lesters. Pretty soon there was an heir in the Lester household. Red, healthy, and male. Cripes—Out Here, too? Okay—josh the parents along. The most wonderful boy in the solar system! Otherwise, matters, there, were much better than before. The camera was in a museum in Washington. The pictures it had contained were on TV, back home. Just another anti-war film, maybe. But impressive, and different. The earnings didn't change Nelsen's life much, nor Gimp's, nor Ramos'. ”

“ Then, I confess, I forgot. In these days one is likely to forget his choicest treasures.”
He turned to the girl. “Beth, who was at the door just now?”
“Two men.” She trembled slightly. “They carried knives, so I opened the door on the outside. They—they hurried away.”
[23]
“I dare say!” The professor chuckled dryly.
“Press the button, Beth,” the professor said, nodding his head toward the right wall. “Our guest will stay for cocoa and cakes, I am sure. That right?” he asked, turning to Johnny.
“I will, yes,” Johnny agreed.
The girl pressed a button like a lamp switch in the wall. ”

“ In ignorance of my acquaintance with Mrs. Netherall, his late father's accomplice, he led me to believe that he was the son of a Manchester merchant, and that his slight German accent had been acquired during his school-days at Wiesbaden.
On the night you met me at the Empire, we had dined together at the Savoy, and perhaps you may have noticed that he was without gloves. He had left them behind in the sitting-room.
Something of a dandy, Ronald Snell, son of the great forger and toxicologist, was most particular about his gloves—pale grey suede ones. ”

“ At the Historical Department of Iowa at Des Moines, and in the library of the Kansas State Historical Society at Topeka opportunity was granted to examine valuable manuscripts. General H. P. McCain, Adjutant-General of the United States, had a search made of the records on file in the archives of the War Department at Washington, and such papers as dealt with Fort Snelling were consulted by the author.
My fellow workers on the staff of The State Historical Society of Iowa have often aided me with suggestions and criticisms. To the Superintendent of the Society, Dr. Benj. ”

“ Florence was about to pass it with a glance when something in the upper outside corner of the cover caught and held her attention. It was the picture of a gargoyle with a letter L surrounding two sides of it. It was a bookmark and, though she had not seen the mark in the missing Shakespeare, she knew from Lucile’s description of it that this must be an exact duplicate.
“Probably from the same library originally,” she thought. “I suppose these charts are worth a great deal of money,” she ventured.
“Oh! yes. A great deal. One doesn’t really set a price on such things. ”
