he backs will need to brace themselves for this.

II. A back is made by two or more players standing close together with
sides toward the jumpers, thus making a back several widths deep to
jump over.

For whichever form of back is used, any player failing to clear the
back without touching it is out of the game, the first two failing
becoming backs for the next round when all have jumped. For large
numbers of players this may be played as a competition between
different groups.

CENTIPEDE

_9 to 12 players._

_Gymnasium; seashore._

The players sit in a circle on the floor, with their feet stretched
out and mingled in a promiscuous pile. One player, who is leader, and
stands outside the circle, touches one of the feet (he may mark it
slightly with a piece of chalk if desired), and calling on some player
by name, commands him to tell to whom the foot belongs. When this
player has named some one, the leader commands the owner of the foot
to stand up. If the guess be wrong, the leader chases the mistaken
player and whips him with a knotted handkerchief. If the guess be
right, the guesser is released from the game, sits down at one side,
and chooses the next one to be It, while the one who was It takes a
place in the circle.

This game lends itself especially to the gymnasium or seashore,
where the dressing of the feet is inclined to be uniform.

The game is played by the modern Greeks.

CHANGING SEATS

_20 to 60 players._

_Schoolroom._

This game is played in several different forms. The following are very
popular.

CHANGING SEATS--I

The teacher gives the command, "Change right!" whereupon each pupil
slips from his own seat to the one across the aisle to the right, the
pupils in the farthest right-hand row standing in the outside aisle.
The next order may be, "Change left!" when all of the pupils slip back
to their own seats, and the row that stood resumes its own.

In the same way the orders, "Change forward!" and "Change backward!"
may be given, the row of pupils left out each time merely standing in
the aisles.

CHANGING SEATS--II

In this form of the game the players in the displaced row run around
the room and take the vacant row of seats on the opposite side. For
instance, the teacher gives an order, "Change left!" whereupon all the
pupils slip over into the seats next to them on the left, the outside
row on the left side of the room standing in the aisle. The tea
