(6) This game is sometimes called Injun, a corruption of Indian. in., probably because the game is a game of extermination. For, in order to win, you must kill all the other players. Hence, you can see that "First" plays at a disadvantage, there being no one for him to kill. If he knocks out a duck he must replace it. If a taw stops inside the ring, that is a fatal shot, for lie has killed himself and is out of the game. So when the first player shoots he does not knuckle down, but toes the taw line and tosses his taw for a good position near the ring.
For good and sufficient Reasons the second player has no desire to get near the first, so he throws his marble with sufficient force to send it through the ring out of reach of First hoping that his taw may be fortunate enough to knock out a duck on its way. Because if number two knocks Out a duck, he can, before replacing the duck, go back to taw and holding the duck in his left hand shoot his taw with his right so that it will strike on the top or side of the duck and fly off rear First's taw, which he may then hit and kill.
--Block, Square Ring, or Big Injun (original meaning in a game)
