half-back. All these sturdy men are ready to rush upon their opponents
the moment full-back's toe touches the ball.

As the rules require the opposite side to stand at least ten yards
back of the middle line, they form themselves in a sort of rough
triangle so as to be able to guard the field and stop the ball with
the least possible waste of time. At the required ten yards back of
the center line, center of the opposing side is posted, back of center
stand the two guards, back of them the two tackles with the quarter-
back between them, behind them the two half-backs are stationed with
full-back in front of his goal.

As there are no rules for placing the men on the field, this formation
is altered to suit the captains.

The player selected to kick the ball must send it at least ten yards
into the opponent's camp, and it is usually sent as much farther as
the judgment of the kicker directs. When the ball comes sailing over
into their ranks the enemy catch it and either return it by a kick or
one of them runs with the ball.

When the player made the kick-off he calculated that the rushers on
his side could reach the ball in time to prevent the enemy making much
headway with it, and the enemy calculated to interfere in all lawful
ways with the kick-off's rushers. If the enemy who holds the ball
starts for a run, the men on the other side tackle him.

As soon as the player and ball are brought to a standstill the runner
cries "down." Then some one on the runner's side places the ball on
the ground at the spot where it stopped, and it is put in play by the
