Under the broad moon it is almost as light as day, and as this strange band emerges into an open space its concomitant elements can be seen to advantage. The man who had first spoken, and who seems to be its leader, is tall, supple, and erect, with straight, regular features; the lower part of the bronzed face is hidden by a thick brown beard, not guiltless even here in these wilds of some attempt at trimming. This, together with his alert and weather-beaten appearance, gives him a much older look than his actual years, for he is quite a young man. The other, he addressed as "doctor," and whose speech is dashed with just a touch of the brogue, is much older. He is a man of medium height, with a quiet refined face, and his hair is just turning grey. Both are armed with a double-barrelled express rifle, revolver of heavy calibre, and sheath knife. The Arab, Somala, and a few others are also armed with Martini rifles; but the bearers of the loads, who are composed of half a dozen nationalities, carry no firearms, though each has a sheath knife of some sort strapped round him--long or short, straight or curved or double-edged, but all wicked-looking weapons enough. The line swings along at an even, wiry-paced walk, to the croon of some wild, weird melody. Then, as, the open space passed, they re-enter the forest shade, they stop short, the whole line telescoping together-- loads colliding, and men falling with them in confusion. For, from the sombre, mysterious depths in front comes a most horrible and appalling sound. A scream, so awful in its long-drawn intensity--so fraught with terror and energy and despair--surely such a cry could never have issued from a human throat. Louder and louder it peals through the grim midnight shades, as though some unknown and gigantic monster were in the last throes of a despairing struggle with countless and overwhelming assailants. Of those who hear it, the superstitious natives huddle together, and trembling in every limb, too scared even to bolt, stand bunched like a flock of bewildered sheep. All save a few, that is, for those immediately in attendance on the leaders come of more virile nationality. Even the two white men are conscious of a wave or superstitious fear thrilling through their veins, possibly the result of climate and condition. "Sidi," whispers Somala, impressively, indicating the direction whence proceeds the horrible sound, "the village is yonder. Mushad has been there, and that is the voice of the dead." "Not so. It is the voice of some one or something very much alive," answers the leader. "And I intend to find out all about it. Eh, doctor?" "Why, of course." "Those who are men and not cowards, come with me," says the leader, shortly.
