The grease on the parchment refused to give way to further polishing, however, and remembering a bottle of ammonia I kept for insect bites, I mixed some with kaffir beer and poured it on the head of the tomtom. One touch of the handkerchief was sufficient once the strong alkali got to work, and out came the grand old face of Nelson and underneath his motto:

"England expects that every man this day will do his duty."

Jack dropped the drum as if it had bitten him.

"What does it mean?" he gasped. "My father had this on his chest. I remember it well!"

I was, however, too busy with the reverse end of the drum to heed him. On the other side the ammonia brought out a picture of the Victory, with the head of a roaring lion below it.

"Good God!" exclaimed Jack. "My father had that on his back. Quick, Jim, rub hard! There should be the family crest to the right—an eagle with a snake in its talons and R. B. underneath."

I rubbed in the spot indicated, and out came the crest and initials exactly as Jack had described them. There was something horribly uncanny and gruesome in finding the tattoo marks of the dead man on the parchment of a Barotse tomtom two hundred miles north of the Zambesi, and for a moment I was too overcome with astonishment to grasp exactly what it meant. Then it came to my mind in a flash that the parchment was nothing else than human skin, and Richard Bridges' skin at that. I put it down with sudden reverence, and, beckoning to its owner, demanded its full history. At first he showed signs of fear, but promising him a waist length of cloth if he told the truth, he squatted on his hams before us and began.

"Many, many moons ago, before the white men came to trade across the Big Water as they do now, two white baases came into this country to look for white stones and gold. One baas was bigger than the other, and on his chest and on his body were pictures of birds, and beasts, and strange things. On his chest was a great inkoos with one eye covered, and on his back a hut with trees growing straight up into the air from it. On his loins was a lion of great fierceness, and coiled round his waist was a hissing mamba (snake). We were sore afraid, for the white baas told us he was bewitched, and that if harm came to either he would uncover the closed eye of the great inkoos upon his chest, which was the Evil Eye, and command him to blast the Barotse and their land for ever.

"So the white men were suffered to come and go in peace, for we dreaded the Evil Eye of the great inkoos. They toiled, these white baases, digging in the hillside and searching the riverbed; and then one day it came to pass that they quarrelled and fought, and the baas with the pictures was slain. We knew then that his medicine was bad medicine, otherwise the white baas without the pictures could not have killed him. So we were wroth and made to slay the other baas, but he shot us down with a fire stick and returned to his own country in haste. Then did I take the skin from the dead baas, for I loved him for his pictures, and I made them into a tomtom. I have spoken."

"Good heavens!" exclaimed Jack when I had translated the story. "Then my father was killed here in Barotseland, and it was Symes, his murderer, who went back to Bulawayo. It was that fiend Symes, also, who took my father's name, probably to draw any money that might have been left behind, and who, as Richard Bridges, was hanged for murder. Poor old dad," he added brokenly, "murdered, and his body mutilated by savages! But how glad I am to know that he died an honest man!"
