I am angry!—Close the fist, place it against the forehead, and turn it to and fro in that position.
Are you friendly?—Raise both hands, grasped, as if in the act of shaking hands, or lock the two forefingers together while the hands are raised.
These signs will be found useful upon the prairie in case of meeting a suspected band. The Indians, like the Bedouin and N. African Moslem, do honor to strangers and guests by putting their horses to speed, couching their lances, and other peculiarities which would readily be dispensed with by gentlemen of peaceful pursuits and shaky nerves. If friendly, the band will halt when the hint is given and return the salute; if surly, they will disregard the command to stop, and probably will make the sign of anger. Then—ware scalp!
Come!—Beckon with the forefinger, as in Europe, not as is done in the East.
Come back!—Beckon in the European way, and draw the forefinger toward yourself.
Go!—Move both hands edgeways (the palms fronting the breast) toward the left with a rocking-horse motion.
Sit!—Make a motion toward the ground, as if to pound it with the ferient of the closed hand.
Lie down!—Point to the ground, and make a motion as if of lying down.
Sleep!—Ditto, closing the eyes.
Look!—Touch the right eye with the index and point it outward.
