For those who care for such things, and would like to try the game, I
give the rules of Jetan as they were given me by John Carter. By
writing the names and moves of the various pieces on bits of paper and
pasting them on ordinary checkermen the game may be played quite as
well as with the ornate pieces used upon Mars.

THE BOARD: Square board consisting of one hundred alternate black and
orange squares.

THE PIECES: In order, as they stand upon the board in the first row,
from left to right of each player.

Warrior: 2 feathers; 2 spaces straight in any direction or combination.

Padwar: 2 feathers; 2 spaces diagonal in any direction or combination.

Dwar: 3 feathers; 3 spaces straight in any direction or combination.

Flier: 3 bladed propellor; 3 spaces diagonal in any direction or
combination; and may jump intervening pieces.

Chief: Diadem with ten jewels; 3 spaces in any direction; straight or
diagonal or combination.

Princess: Diadem with one jewel; same as Chief, except may jump
intervening pieces.

Flier: See above.

Dwar: See above.

Padwar: See above.

Warrior: See above.

Thoat: Mounted warrior 2 feathers; 2 spaces, one straight and one
diagonal in any direction.

Panthans: (8 of them): 1 feather; 1 space, forward, side, or diagonal,
but not backward.

Thoat: See above.

The game is played with twenty black pieces by one player and twenty
orange by his opponent, and is presumed to have originally represented
a battle between the Black race of the south and the Yellow race of the
north. On Mars the board is usually arranged so that the Black pieces
are played from the south and the Orange from the north.

The game is won when any piece is placed on same square with opponent's
Princess, or a Chief takes a Chief.

The game is drawn when either Chief is taken by a piece other than the
opposing Chief, or when both sides are reduced to three pieces, or
less, of equal value and the game is not won in the ensuing ten moves,
five apiece.

The Princess may not move onto a threatened square, nor may she take an
opposing piece. She is entitled to one ten-space move at any time
during the game. This move is called the escape.

Two pieces may not occupy the same square except in the final move of a
game where the Princess is taken.

When a player, moving properly and in order, places one of his pieces
upon a square occupied by an opponent piece, the o
