are "Suppose you try. But first see if there any brass things that the magnet pulled." Charlie looked them over. Then we tried the casters of my chair, and all the other brass things we could find, none of which the magnet would pull. "There's no use in trying any longer,” said Charlie. "It won't pull brass." 66 'Then, there's another matter settled,” I said. "The magnet does not pull brass. Is there any thing else it does not pull?” "Wood," said Charlie. "I tried lots of pieces." 66 Any thing else?" Stones," said Charlie, eagerly. "What are these?" I asked, holding up a couple of heavy stones he had put among the things the magnet pulled. "I guess I put those there by mistake," said Charlie, testing with the magnet a number of stones in the other pile. "Try them," I said. "O!" he said, as the magnet lifted them; "I forgot. It does lift some stones." .6 'Well, what else have you in that pile of things the magnet did not pull ?" "Glass, leather, lead, bone, cloth, tin, zinc, corn, and a lot of things." "Very well. Now let us see what the magnet does pull." "Iron keys," said Charlie, "and nails." "Here's a nail in this other pile. "That's a brass nail. The magnet only pulls iron nails.” 66 What else have we in this pile?” "Needles, hairpins, screws, wire-iron wire," he added quickly. "Brass wire doesn't stick, you know.” "How about this?" I asked, taking a small coil of copper wire from my desk. "I guess that won't stick," said Charlie. "Because that's copper wire, and the magnet doesn't seem to pull any thing that isn't iron." Much to Charlie's satisfaction, the magnet did not pull the copper wire. Then I took up two stones, one rusty red, the other black, and said: "What about these ?" "I guess they must have iron in them too," said Charlie. Have they?" 66 66 "They have," I replied. "They are iron. ores from which iron is made. Why did you think there was iron in them ?" "Because they wouldn't have stuck to the magnet if there wasn't." "Quite true. So you have learned another very important fact. Can you tell me what it is?" "The magnet pulls iron," said Charlie. "Good," said I; "and it is also true that the magnet does not pull-" "Things that are not iron," said Charlie. "True again,” I said. "So far as our experiments go, the magnet pulls iron always, and never any thing else." "But what makes it pull iron?" "That I can not tell. We see it does pull, but just how the pulling is done, or what makes it, no one has yet found out. "For convenience we call the pulling power magnetism. You may keep the magnet, and at some other time, I will tell you more about it." Language Lesson.-Name six words in the lesson, each of which is made up of two words by leaving out letters. Write out the two words in each case. What is the name of the mark which shows the omission of letters? Point out the statement, command, question, and exclamation in the sentences given below. "O, isn't it a funny horseshoe!" "What made it jump so?" "Put the bar back." "The magnet pulls iron." There are few sights more pleasing than a herd of tall and graceful giraffes. With their heads reaching a height of from twelve to eighteen feet, they move about in small herds on the open plains of Africa, eating the tender twigs and leaves of the mimosa and other trees. The legs of a large giraffe are about nine feet long and its neck nearly six feet; while its body measures only seven feet in length and slopes rapidly from the neck to the tail. The graceful appearance of the giraffe is increased by the beauty of its skin, which is orange red in color and mottled with dark spots. Its long tail has at the end a tuft of thick hair which serves the purpose of |
