Some cattle have been stolen a week or so ago and every man suspects his neighbour of the crime. The real malefactor, however, is known only to the Spirits, and they alone can expose him. As their cares and interests are too multifarious to permit them to appear in person on the earth, our Sorcerer declares that they have assigned to him their powers and functions for the occasion. To-day he will be their mouthpiece. He takes an egg lightly between his thumb and first finger, pressing the ends with two other fingers. At his request a young assistant proclaims in a wailing voice the names of all the neighbouring lands. He cannot believe, he tells us, that a fellow countryman should be guilty of so dastardly an outrage. But the recital is over and the egg has not trembled. There is nothing left but to call out the name of his own village. Alas! No sooner are the words uttered than an ominous crack is heard and a sticky yellow fluid issues from the shell, now broken in two. Recourse must now be had to the evidence. The circle of inquiry is narrowed and it only remains to discover the guilty individual.

The first experiment has proved far too successful to be discarded in favour of any innovation. An egg, balanced in the same way as before, will be the sole cost of the continued investigation. The same unsophisticated youth now proceeds to recite the names of all the inhabitants of the village. In most cases he designates them by their nicknames. The "Squirrel," the "Pagoda Cock" and the "Marabout" are at present white as snow. They all appear to heave an immense sigh of relief as their names are called out without any sign of expostulation from the egg. It is plain that their belief in the justice of the Spirits is far from profound. They lose no time in vanishing from the scene.

Suddenly, just as the youthful voice proclaims "The Scorpion," the egg unmistakably collapses. The malefactor thus indicated is a broken-down old man, an object more of sympathy than of suspicion. His rickety frame is supported with considerable difficulty by his legs, which are swollen to an unnatural degree by gout. But the eye of the Spirits is piercing, their justice unfailing. No escape for the guilty is possible. However, as the accused protests his innocence with all the emphasis at his command, the Pholy condescends to allow him to prove it by submitting to the ordeal prescribed by the Gods. Two alternatives are offered to him, the ordeal by water and that by boiling resin, in which an innocent man may plunge his hand and withdraw it unharmed.

"The Scorpion" is not slow to choose the former. The divine instrument of trial is near at hand in the shape of a river which flows within a short distance of the sacred judgment tree. While the preparations for the ordeal are going forward, the accused asks for permission to make a preliminary statement. If he can associate an accomplice with him in the crime it will doubtless mitigate his punishment. Accordingly he formally names another villager as his partner in transgression. The alleged partner's vigorous denials are followed by immediate arrest. The question now is as to the respective degrees of guilt, a point which the river will ultimately settle. Two stakes are driven into the middle of the stream at a point where the depth is about ten feet. The unfortunate victims are conveyed by canoe to the spot and left clinging desperately to the stakes while trying to keep their heads under water as long as possible. The test is quite simple. The one who loses his breath and comes up to the surface first stands convicted of being the principal in the theft, while his larger-lunged rival is cleared of everything save the charge of complicity.

In a few seconds the performance is over, for the unhappy "Scorpion," already paralysed by fear of the immersion, cannot hold his breath at all, and bobs up to the surface immediately, half asphyxiated. The Sorcerer, delighted at the result of his experiment, expresses his appreciation in a series of approving gestures.

The principle of the ordeal rests on the belief, prevalent among the great majority of half-civilized races, that the tutelary deity of any individual withdraws his protection and assistance if his "ward" has violated any of the fundamental principles of morality, or neglected the rites and ceremonies enjoined by his religion.

This notion of loss of protection of a higher power may possibly be associated with the vague idea of a conscience. It is certainly one of the most curious conceptions which research into the science of divination has brought to our notice. The submission of a suspected criminal to trial by ordeal is an invitation to the Spirits to give a manifestation of their desires.

There are many forms of this species of divine interrogatory, varying in number and character in different parts of the world. Fifty varieties at least are met with in Africa. It is not to be believed, however, that every ordeal is dangerous or even necessarily harmful. Many forms are known far less cruel than those which arrest the imagination of the traveller by virtue of their more inhuman incidents, such as the ordeal by boiling water, molten lead, or poison dropped into the eyes.

Thus, among the Moï, a favourite ordeal is to compel the accused to drink an excessive quantity of water or alcohol resulting in temporary discomfort without danger or permanent injury.

In Africa cases are known where an ordeal is carried through without the suspected criminal knowing of it. For example, it has been considered sufficient to observe the direction in which the smoke of a chimney is blown, or to set a trap in some place known to be frequented by rats. The innocence or guilt of the accused will be determined according to whether a rat is caught or not.
