The same superstition is turned to account by hunters in many parts of the world for the purpose of running down the game. Thus a German huntsman will stick a nail taken from a coffin into the fresh spoor of the quarry, believing that this will hinder the animal from escaping. The aborigines of Victoria put hot embers in the tracks of the animals they were pursuing. Hottentot hunters throw into the air a handful of sand taken from the footprints of the game, believing that this will bring the animal down. Thompson Indians used to lay charms on the tracks of wounded deer; after that they deemed it superfluous to pursue the animal any further that day, for being thus charmed it could not travel far and would soon die. Similarly, Ojebway Indians placed "medicine" on the track of the first deer or bear they met with, supposing that this would soon bring the animal into sight, even if it were two or three days' journey off; for this charm had power to compress a journey of several days into a few hours. Ewe hunters of West Africa stab the footprints of game with a sharp-pointed stick in order to maim the quarry and allow them to come up with it. But though the footprint is the most obvious it is not the only impression made by the body through which magic may be wrought on a man. The aborigines of South-eastern Australia believe that a man may be injured by burying sharp fragments of quartz, glass, and so forth in the mark made by his reclining body; the magical virtue of these sharp things enters his body and causes those acute pains which the ignorant European puts down to rheumatism. We can now understand why it was a maxim with the Pythagoreans that in rising from bed you should smooth away the impression left by your body on the bed-clothes. The rule was simply an old precaution against magic, forming part of a whole code of superstitious maxims which antiquity fathered on Pythagoras, though doubtless they were familiar to the barbarous forefathers of the Greeks long before the time of that philosopher. 4.
