"you've heard about doing evil that good might come from it," [elinora] said. "well, mother mine, it's something like that with me. i'm willing to bear the hard part to pay for what i'll learn. already i have selected the ward building in which i shall teach in about four years. i am going to ask for a room with a south exposure so that the flowers and moths i take in from the swamp to show the children will do well." 18 "you little idiot! " said mrs. comstock. "how are you going to pay your expenses? " 19 "now that is just what i was going to ask you! " said elnora. "you see, i have had two startling pieces of news to-day. i did not know i would need any money. i thought the city furnished the books, and there is an out-of-town tuition, also. i need ten dollars in the morning. will you let me have it? " 20 "ten dollars! " cried mrs. comstock. "ten dollars! why don't you say a hundred and be done with it! i could get one as easy as the other. i told you! i told you i couldn't raise a cent. every year expenses grow bigger and bigger. i told you not to ask for money! " 21 "i never meant to," replied elnora. "i thought clothes were all i needed and i could bear them. i never knew about buying books and tuition." 22 "well, i did! " said mrs. comstock. "i knew what you would run into! but you are so bull-dog stubborn, and so set in your way, i thought i would just let you try the world a little and see how you liked it!
