4. Lastly, the eccentric movements we have mentioned depend on a well-ascertained but mysterious property of camphor, viz., that when placed on the surface of the water, it moves spontaneously. It is a well-known fact that a morsel of camphor placed in a glass of water will, after a few moments, begin to move either with a sidelong or rotary movement; such movement being due, according to some authorities, to the recoil produced by an escape of liberated gases; according to others, to a mysterious force inherent in the surface of liquids, and known as superficial tension.

Amusing the Children.

A clever way to amuse a party of children is to invite them to a peanut party. Tiny cards of invitation are sent out, on each of which two half peanut shells are fastened. A large quantity of the nuts are hidden about the house, and when the young folks arrive they are told to hunt them. They who find the most and least of them receive prizes.

Another is a soap bubble party. The invitations for this should have a pen and ink sketch of a pipe and bubble. Provide plenty of clay pipes, with the name of a guest written on each, and make the soapsuds with the addition of glycerine to make the bubbles strong and tough. For the prizes for the most successful bubble blower, a fancy pipe is suitable. It can be made by gilding the handle and outside of the bowl of a clay pipe and painting the inside of the bowl in water colors. A bow of baby ribbon to match the paint improves it. For the booby prize a little pipe can be made from a match and half an acorn shell.

A penny party furnishes amusement for an evening. With the invitations is sent a request for each guest to bring a penny, not for an admission fee, but for use. For each guest there are provided two cards and a pencil; one card is blank; the other has a list of the things to be found on a penny. The list is numbered, and each person is expected to name as many as he can, prizes being awarded for the best and poorest list. Find—1. Top of hill. 2. Place of worship. 3. An animal. 4. A fruit. 5. A common fruit. 6. Links between absent friends. 7. Union of youth and old age. 8. A vegetable. 9. Flowers. 10. What we fight for. 11. A metal. 12. A messenger. 13. A weapon of defence. 14. A weapon of warfare. 15. A body of water. 16. A beverage. 17. What young ladies want. 18. The most popular State. 19. What men work for. 20. Sign of royalty. 21. A jolly dog. The answers are—1. Brow. 2. Temple. 3. Hare (hair). 4. Date. 5. Apple. 6. Letters. 7. 1894 (the date of the penny). 8. Ear. 9. Tulips (two lips). 10. Liberty. 11. Copper. 12. One sent (cent). 13. Shield. 14. Arrow. 15. Sea (c). 16. Tea (t). 17. Beau (bow). 18. United States (matrimony). 19. Money. 20. Crown. 21. A merry cur (America). Usually a half hour is allowed for filling out the blank cards, and after that some time for correcting the lists and awarding prizes.

It is often hard to find games for evening amusements that will amuse all. Some are so noisy that the sensitive cannot enjoy them, but the following will instruct as well as amuse: One is to transpose the misplaced letters of words, usually the name of a city. To prepare for the game make a large quantity of small cards from pasteboards, about an inch and a half square. Paste a large letter on each one, cut from a newspaper or advertisement, having several for each letter of the alphabet. Give to each the letters necessary to spell a word and let him study it out. Thus the letters ilisyantp can be made to spell Ypsilanti, or stoonb Boston.

Another game which is quite entertaining is called a pronunciation match. Any number can play. One is elected as leader. At first he will call out a letter, as a, and each person must think quickly while he counts five, and be ready to tell the name of a city in the State agreed upon before the contest begins. For instance, the leader, while he counts five, points to one of the company who must give the name of a city beginning with the letter A, B or C, as the leader may announce. When one answer has been given, he quickly counts again, and points to another person until some one fails to respond, when he is declared leader and also pays a forfeit. It is very amusing and teaches people to think quickly and keep their wits about them.
