FAMILY FUN

A Good Puzzle.— Here is a puzzle which you may try to see what you can do with : Tie a string about a yard long to a door key and take' the string in the right hand. Hold it so the key will clear the floor four or five inches. If you will hold the string steady enough, it 'will begin to swing back afid forth dn a straight line. Let another person take your left hand in his, and the motion of the key wilb change from the pendulunWike swing to a circular swing. If a tMrd person will place his hand on the shoulder of the second person, the key will stop. Just try the above and then solve the puzzle.

A Brown Paper Magnet.— A very simple and interesting electrical experiment may be made with a sheet of brown paper, illustrating in a remarkable manner how the most astonishing effects may be produced- by the simplest means. T&lfie a sheet of coarse brown paper and after holding it before the fire unl/il it is perfectly -dry fold ht u|p into a long strip about two inches wide. The rragnetis now complete. To exhibit its attractive power cut some s.trips of writing, paper a/bout three inches long and about as wide one of these lines, then place them upon the tab-le, three or four- together. Now take the magnet and draw it briskly tinder the arm two or three times. Its electro magnetism is instantly developed and becomes apparent when held over the small strips of writing paper, 'for they fly up from the table toward the paper magnet veritably ' by the wings of 'lightning.'
