BALLS AND BEAN BAGS
SPECIFICATIONS FOR BALLS, BEAN BAGS, MARKING GROUNDS, ETC.
BALLOONS.—Gas balloons have been found very useful for quite a large class of games, and are specially suitable for use in the schoolroom or parlor, though they may also be used out of doors. The balloons are the regular toy balloons used by children, and are preferably ten or twelve inches in diameter when inflated, though smaller ones may be used. In games where two balloons are used it is desirable that they be of different colors, to distinguish which belongs to each team. When the gas in a balloon is exhausted, if it be not convenient to refill the rubber bag with gas, it may be filled with the breath, and will be found still to float sufficiently in the air for purposes of the game, though of course the gas-filled balloons with their tendency to rise are superior.
BASEBALL (See also Indoor Baseball).—Baseballs are hard and preferably leather covered. The required ball for the National Association of Baseball Leagues is not less than 5 nor more than 5-1/4 ounces in weight, and measures not less than 9 nor more than 9-1/4 inches in circumference. A slightly smaller ball is used in junior play; that is, for boys under sixteen. The best construction of baseballs is that in which there is a rubber center wound with woolen yarn, the outside covering being of white horsehide. Good balls cost from fifty cents to $1.50 each, but baseballs may be had at five cents each.
BASKET BALL.—Basket balls are comparatively large, round, "laced" balls; that is, they consist of a rubber bladder inserted in a leather case; the bladder is inflated by means of a hand or foot pump; after it is placed inside of the leather cover the opening in the cover is laced together. The official ball prescribed by the Amateur Athletic Union and the Young Men's Christian Association Athletic League of North America calls for one that measures, when inflated, not less than 30 nor more than 32 inches in circumference; the limit of variableness to be not more than 1/4 inch in three diameters; the weight to be not less than 18 nor more than 20 ounces; the ball when ready for use to be tightly inflated and so laced that it cannot be held by the lacing. The best basket balls cost about $6 each.
