answer. Finally, the papers are unfolded and read. QUICK MOTION, Experiments on. The following experiments are all explained by the fact that motion can be imparted to objects but gradually, and that when it is done suddenly the objects often prefer to break or give way, rather than pass the motion along, though it seems easier to do the latter. 1. Place a silver dollar on a visiting card, the edge of the card projecting half an inch beyond the edge of the table. If the card is moved gradually, it will carry the coin with it; but if it be snapped suddenly it will slide under the coin, which will not move. If the coin and card be placed on a wine-glass when the experiment is tried, the coin will fall into the glass. 2. Pile about ten checkers one on another. If one in the middle of the pile be pushed slowly with the edge of a ruler, the pile will be overturned; but if it be struck sharply with the ruler, taking care to give a perfectly horizontal blow, it may be knocked from the pile, leaving the remainder upright. 3. Suspend a small stick by one end from a string several feet long. If the stick be pushed slowly by a heavier stick, it will simply swing; but if struck sharply, it may be broken, the string moving very little. Experiment 4. one of these threads. If the other be pulled slowly, straight downward, the upper string will break; but if it be jerked suddenly, the lower one will break. 5. Fix a needle at each end of a broomstick, and support it by resting the needles on the edges of two wine-glasses, which stand on chairs. By striking the broomstick violently in the middle with a stout stick, it may be broken without injuring the glasses. QUININE, Experiments with. I. Dissolve some quinine by putting a few grains into a bottle of water and leaving it two or three days, shaking it occasionally. It will dissolve quicker if a little tartaric acid, or a drop of sulphuric acid be added. Admit a sunbeam from a HELIOSTAT into a darkened room, and place a piece of dark blue glass over the aperture. Hold the bottle of quinine solution in the beam of light and it will glow with a curious blue color which seems to come from within the fluid. By holding a bottle of pure water beside it, the difference between them will be perceived at once. 2. Into a glass of clear water held in the beam of blue light pour a little of the quinine solution. It will appear like a slowly descending blue cloud. are usually two pins driven into the ground, about eighteen yards apart. The players, who may be either two or three playing singly against each other, or four or six divided into equal sides, are each provided with an equal number of quoits, generally two. Each player, in turn, stands beside one hub and pitches his quoits so that they will fall and be as near as possible to the other hub. The first figure shows the manner of holding the quoit. Sometimes an expert player succeeds in encircling the hub with one of his quoits (called making a “ringer"), but this is very difficult. This property of quinine is called fluorescence. Another fluorescent substance is chlorophyl, the green coloring matter of leaves. It can be obtained by boiling tea leaves, pouring off the water and adding more from time to time, till it ceases to taste of tea. Then soak the This and other positions of the leaves in hot alcohol, which will dis- quoit at the hub are shown in the solve the chlorophyl. This solution | last figure. A is a ringer, B is called a treated like the quinine above gives "cutter," and C is said to be “pitched a red light. A solution of madder true." mixed with alum produces a yellow fluorescence, soot dissolved in alcohol, a greenish blue, and petroleum a green. B Holding the Quoit. QUOITS, a game generally played on level sward, by two or more persons, with flat iron rings or disks, which are pitched at a goal or hub. The hubs, sometimes called motts, Position of Quoits at the Hub. After the first player has pitched all his quoits, the second player takes his turn, and then the others, if there are more than two. When all have played, all go to the other hub and reckon up the points, he whose quoits lie nearest to the hub counting one point for each quoit ; but each quoit entitled to count must be nearer the hub than any of the opponent's quoits. The quoits are generally numbered or otherwise marked so that those belonging to each player can be easily known. When the points have been reckoned, the players then pitch their quoits at the other hub, and so on alternately until the game is won by one of the players or sides getting the requisite number of points. The number of points in the game is agreed on by the players beforehand, but it is usually eleven or twentyone. He who rings the hub counts ten points towards the game. Boys floor. often play quoits with flat stones, a board which is placed on the which may easily be rounded so as to make them almost as good as iron ones. They use also a small stone instead of an iron pin for a hub. RULES OF THE GAME. 1. The hub-pin must be driven in so as to project not more than half an inch above the surface. 2. Each player may select quoits of any size he chooses. 3. In pitching, each player must stand within three feet of the hub. 4. The distance of a quoit from the hub must be measured from the middle of the hub to the nearest visible point of the quoit. Thus, if the quoit is stuck into the ground, the part beneath the surface does not count. Parlor Quoits. Quoits for use in the parlor are sold at toy stores. They are usually made of rubber, Discobolus. and the hub, or short stake, at which they are pitched, is fixed in ( A game called "faba baga," which is also sometimes called "parlor quoits," is played by tossing beanbags at a hole in a board. History. Pitching quoits was a favorite amusement among the ancients. The Greeks and Romans played with a kind of quoit called a discus, which had no hole in it, but was solid, like a plate. The illustration shows the celebrated Greek statue called the discobolus (discus-thrower), the work of the sculptor Myron, of which there are copies in the Vatican and elsewhere. In England the hub or pin was formerly called the "hob." Countrymen, who could not get quoits of the proper form, played with horseshoes, and in some parts of England a quoit is still called a "shoe." The word quoit is from the provincial English coit, to throw. QUOTATIONS. A game played by any number of persons, who sit in a row or circle. One begins by repeating a quotation, either prose or poetry, and the next must then give one, the first word of which begins with the same letter as the last word of the quotation just given. The game goes on thus as long as the players choose. Any one who does not give his quotation in one minute (or any other time agreed on before the game) pays a forfeit. Instead of paying a forfeit, he may be required to leave the game, and it may thus be continued till only one is left, who is declared the winner. Any player may be required to tell the author of his quotation, or even the book, poem, or play where it is to be found, if it is so agreed. The following example shows how the quotations may follow each other: Know ye the land where the Cypress and "Man never is, but always to be, blest."-Pope. "Belgium's capital had gathered there, Her beauty and her chivalry."-Byron. "Come and walk with us, the Walrus did beseech."-Carroll. etc., etc. R RACKETS, or RACKET (some- rackets, but longer and smaller in the face, and the balls are hard, about an inch in diameter, weighing an ounce. times spelled Racquet), a game played by two or four persons with rackets and a ball, in a court surrounded by four walls. The floor is evenly paved, and marked as in the diagram: G E A B Racket Court. с D H The players decide by lot, or in any other way they choose, on the one to begin the game, who is called the "In-player" or " Man_in." He stands in one of the service-spaces, and with his racket strikes or "serves" the ball so that it bounds from the front wall above the cutline into one of the courts: C, if he served from B; and D, if from A. One of the players on the other side, called the Out-player, stands in readiness to take the service," that is, to strike the ball either on the bound or before it has reached the ground. The Out-player may stand wherever he wishes, but in case of a double match, the two other players must stand behind the In-player till the ball is served. For double matches, with two persons on a side, the court was formerly 80 by 40 feet, but for single matches it was smaller. Of late years the standard court for both kinds of matches has been 63 by If the ball is served wrongly, it is 31 feet. The walls E, F, G, H are a fault, and when the server makes black on the inside, and the balls two consecutive faults his "hand is used are sometimes whitened by out." that is, he becomes the Outshaking them in a bag with some player, and his adversary serves. white powder, so that they will leave After a good service the ball is marks on the black wall where they struck by the players alternately strike.

In the court there is usually an attendant called the Marker, who scores for the players and acts as umpire. The rackets used are similar to TENNIS 64 After the service, the ball may strike one or more of the other walls of the court after it has bounded from the front wall, and a skilful player often makes very puzzling strokes by driving the ball into a corner, where it bounds about from and must not touch the floor, the one wall to another. This is the galleries, the telltale, or any wood or principal difference between Rack-netting, or above the cemented lines ets and LAWN TENNIS. In Rackets, of the courts, before or after reachas in the latter game, the player can ing the front wall. make the ball bound in different directions by "cutting" it, and as the ball has four walls to bound from, as well as the floor, a "cut" often causes it to take a very unexpected course. RULES OF THE GAME. The following rules are those of the New York Racquet Court Club, and have been adopted by the National Amateur Athletic Union: 1. The game to be 15 up. At 13 all, the out players may set to 5; and at 14 all, to 3; provided this be done before another ball is served. ["Set to 5" means that instead of playing the remaining 2 Aces of the fifteen, 5 Aces are played. "Set to 3." that instead of the remaining one Ace 3 are played.] 2. On commencing the game, in a double match, whether odds be given or not, the side going in first to serve shall have but one hand; but in a single match the party receiving odds shall be entitled to them from the beginning. 3. The ball shall be served alternately right and left, beginning on whichever side the server chooses. 4. The server must stand with at least one foot in the "service box," and serve the ball over the line on the front wall and within the proper service-court; otherwise it is a "fault." Serving two faults, missing the ball, or the ball served striking anywhere before it reaches the front wall, is a hand-out. 5. All balls served or played into the galleries, hitting a beam, iron rod, the telltale, or any wood or netting, or above the cemented lines of the courts, although they may return to the floor, count against the Striker. 6. A ball, to be fair, must be truck before or on the first bound, 7. Until a ball has been touched or bounded twice it may be struck at any number of times. 8. Only the player to whom a ball is served may return it. 9. A ball touching the striker or his partner before the second bound loses a hand or an ace. 10. If a fair ball hit the striker's adversary above or on the knee, it is a "let," and shall be played over; if below the knee, it counts against the striker. 11. The out-players may once only in each game exchange courts to return service. 12. Every player should try to keep out of his adversary's way. When a "hinder" is claimed it shall be decided by the marker. 13. The marker's decision, on all questions referred to him, shall be final. If he is in doubt he should ask advice; and if he cannot decide positively, the ace is to be played over. History. Rackets is a modification of Court TENNIS. It has long been popular in England and Ireland, and has been recently introduced into this country, where several clubs have been formed to play it. The New York club has a fine court on 26th Street, near the corner of Sixth Avenue. Fives, a kind of Rackets in which the palm of the hand is used instead of the racket. There is only a front wall in the court, the others being replaced by lines drawn on the ground. In Italy is played a kind of Fives called Pallone, in which the ball is struck with the arm, protected from wrist to elbow with a guard of heavy leather. RAILROAD BAGATELLE. BAGATELLE.
