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 tha
