Prоvide the аuthоr (1 pt.), title (1 pt.), аnd 2-3 cоmplete sentences explаining the significance (3 pt.) of five of the following quotes. Make sure you number each answer to match the quote you are discussing. 1. "Where is your mother?” “Oh, she too had died but a short time since; she broke a blood-vessel in a fit of passion at a New England peddler.” There was a drop of comfort, at least, in this intelligence. The honest man could contain himself no longer. He caught his daughter and her child in his arms. “I am your father!” cried he— 2. Standing on the bare ground,—my head bathed by the blithe air and uplifted into infinite space,—all mean egotism vanishes. I become a transparent eyeball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or particle of God. 3. I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived. . .I wanted to live deep and suck out all the marrow of life... 4.

Though conscious of the difficulty of learning without a teacher, I set out with high hope, and a fixed purpose, at whatever cost of trouble, to learn how to read. 7. I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good as belongs to you. I loafe and invite my soul, I lean and loaf at my ease observing a spear of summer grass. 8. God preaches, a noted Clergyman - And the sermon is never long, So instead of getting to Heaven, at last - I'm going, all along.
