t, leaving
a seat at the rear for the "last man." There may be no moving of this
kind, however, until the runners are out of the aisle.

As in all running games in the class room, the seated players must
keep their feet under the desks and out of the aisles.

It will be seen that all of the players must be very alert to watch
the actions of the runner, but especially those sitting in the front
seats, as at any moment one of them may have to become runner. The
last man must never fail to call out the words "Last man!" when he
takes his stand at the rear of a row of seats. He is not considered to
have taken refuge until he does this.

LEADER AND FOOTER

_50 to 60 or more players._

_Playground; gymnasium._

This is a leapfrog game. One player is chosen to be "back," and he
chooses a leader, generally the poorest jumper, and a "footer"--the
best jumper. A starting or "taw" line is drawn on the ground and the
back stands with his side parallel to it. The other players line up in
single file at some distance, with the leader at the head and the
footer at the rear of the line. The footer dictates the way in which
the back is to be cleared and his distance from taw. For instance, he
may, having put a long distance between the back and the line, require
a run of a limited number of steps, or a hop and skip (specifying the
number), before the jump. The leader makes the first jump as
prescribed by footer, and the others, in turn, including the footer.
Any player failing in the feat becomes back. Any player who is
doubtful of success may call upon the footer to perform the feat. If
the footer fails, he becomes the back. If the challenge be
successfully met, the one making the challenge becomes back.

LEAPFROG

The back.--Any player who bends over to make a back for others
to leap over is called the "back." He must rest his hands on
his knees or near them to make a firm back. It is against the
rules for any player making a back to throw up his back or bend
it lower while a player is leaping over it; but each player,
before jumping, may say "High back!" or "Low back!" which the
one who is down must adjust before the jumper starts. He then
must do his best to keep the back perfectly level and still,
unless the game calls for a different kind of play. In some
games the back stands with his back toward the jumpers, and in
others with his side toward them. If
