CHAPTER VI

THE RAT MORT

I

The guide had stepped out of the house into the street, Yvonne following closely on his heels. The night was very dark and the narrow little Carrefour de la Poissonnerie very sparsely lighted. Somewhere overhead on the right, something groaned and creaked persistently in the wind. A little further on a street lanthorn was swinging aloft, throwing a small circle of dim, yellowish light on the unpaved street below. By its fitful glimmer Yvonne could vaguely perceive the tall figure of her guide as he stepped out with noiseless yet firm tread, his shoulder brushing against the side of the nearest house as he kept closely within the shadow of its high wall. The sight of his broad back thrilled her. She had fallen to imagining whether this was not perchance that gallant and all-powerful Scarlet Pimpernel himself: the mysterious friend of whom her dear milor so often spoke with an admiration that was akin to worship. He too was probably tall and broad--for English gentlemen were usually built that way; and Yvonne's over-excited mind went galloping on the wings of fancy, and in her heart she felt that she was glad that she had suffered so much, and then lived through such a glorious moment as this.

Now from the narrow unpaved yard in front of the house the guide turned sharply to the right. Yvonne could only distinguish outlines. The streets of Nantes were familiar to her, and she knew pretty well where she was. The lanthorn inside the clock tower of Le Bouffay guided her--it was now on her right--the house wherein she had been kept a prisoner these past three days was built against the walls of the great prison house. She knew that she was in the Carrefour de la Poissonnerie.

Question: CHAPTER VIII

Kate was stirring early, but not as early as her sister, who met her on the threshold of her room. Her face was quite pale, and she held a letter in her hand. "What does this mean, Kate?"

"What is the matter?" asked Kate, her own color fading from her cheek.

"They are gone--with their horses. Left before day, and left this."

She handed Kate an open letter. The girl took it hurriedly, and read--

"When you get this we shall be no more; perhaps not even as much. Ned found the trail yesterday, and we are taking the first advantage of it before day. We dared not trust ourselves to say 'Good-by!' last evening; we were too cowardly to face you this morning; we must go as we came, without warning, but not without regret. We leave a package and a letter for your husband. It is not only our poor return for your gentleness and hospitality, but, since it was accidentally the means of giving us the pleasure of your society, we beg you to keep it in safety until his return. We kiss your mother's hands. Ned wants to say something more, but time presses, and I only allow him to send his love to Minnie, and to tell her that he is trying to find the red snow.

"GEORGE LEE."

"But he is not fit to travel," said Mrs. Hale. "And the trail--it may not be passable."

"It was passable the day before yesterday," said Kate drearily, "for I discovered it, and went as far as the buck-eyes." 1. who was stirring?
2. when?
3. who got up first?
4. was she flush?
5. where did they meet?
6. who was gone?
7. what was given to kate?
8. by who
9. who left the letter
10. what was found?
11. by who?
12. when?

Q: In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values "true" and "false", usually denoted 1 and 0 respectively. Instead of elementary algebra where the values of the variables are numbers, and the prime operations are addition and multiplication, the main operations of Boolean algebra are the conjunction "and" denoted as , the disjunction "or" denoted as , and the negation "not" denoted as . It is thus a formalism for describing logical relations in the same way that ordinary algebra describes numeric relations.

Boolean algebra was introduced by George Boole in his first book "The Mathematical Analysis of Logic" (1847), and set forth more fully in his "An Investigation of the Laws of Thought" (1854). According to Huntington, the term "Boolean algebra" was first suggested by Sheffer in 1913.

Boolean algebra has been fundamental in the development of digital electronics, and is provided for in all modern programming languages. It is also used in set theory and statistics.

Boole's algebra predated the modern developments in abstract algebra and mathematical logic; it is however seen as connected to the origins of both fields. In an abstract setting, Boolean algebra was perfected in the late 19th century by Jevons, Schroder, Huntington, and others until it reached the modern conception of an (abstract) mathematical structure. For example, the empirical observation that one can manipulate expressions in the algebra of sets by translating them into expressions in Boole's algebra is explained in modern terms by saying that the algebra of sets is "a" Boolean algebra (note the indefinite article). In fact, M. H. Stone proved in 1936 that every Boolean algebra is isomorphic to a field of sets.
