My memory went back to a tall, sunburnt man with a kindly manner who had come down to the school one day and put up a glorious feed at the tuck shop to Jack and his friends. Afterwards, at his son's urgent request, he had bared his chest to show us his tattooing of which Jack had, boy-like, often boasted to us. I recalled how we had gazed admiringly at the skilfully worked picture of Nelson with his empty sleeve and closed eye and the inscription underneath: "England expects that every man this day will do his duty." Jack had explained with considerable pride that this did not constitute all, as on his father's back was a wonderful representation of the Victory, and on other parts of his body a lion, a snake, and other fauna, but Richard Bridges had protested laughingly and refused to undress further for our delectation.

We reached Bulawayo, but no one in the city appeared to recall the case at all; indeed, Bulawayo had grown out of all recognition since Richard Bridges had passed through it on his prospecting trip. It was difficult to know where to start. Even the police could not help, and had no knowledge of where the murderer had been buried. No one but an old saloon-keeper and a couple of miners could recollect the execution even, and they, so far as they could remember, had never met Richard Bridges in the flesh, though his unsavoury reputation was well known to them.

In despair, Jack suggested a trek up country towards Barotseland, which was the district that Bridges and Symes had proposed to prospect, though, according to all accounts, Symes had been murdered by the Matabele before they reached the Guai river.

For the next month we trekked steadily northwards, having very fair sport; but, as I expected, extracting no information whatever from the natives about the two prospectors who had passed that way years before. At length, Jack became more or less reconciled to failure, and realising the futility of further search suggested a return to Bulawayo. As our donkey caravan was beginning to suffer severely from the fly, I concurred, and we started to travel slowly back to Bulawayo, shooting by the way.

One night after a particularly hard trek we inspanned at an old kraal, the painted walls of which told that at one time it had served as a royal residence, and as I had shot an eland cow that afternoon, which provided far more meat than we could consume, we invited the induna and his tribe to the feast. Not to be outdone in hospitality, the old chief produced the kaffir beer of the country, a liquid which has nothing to recommend it beyond the fact that it intoxicates rapidly.

A meat feast and a beer drink is a great event in the average kaffir's life, and as the evening wore on a general jollification started to the thump of tomtoms and the squeak of kaffir fiddles. There was one very drunk old Barotse, who sat close to me, and, accompanying himself with thumps on his tomtom, sang in one droning key a song about a man who kept snakes and lions inside him, and from whose chest the evil eye looked out. At least, so far as I could gather that was roughly the gist of the song; but as his tomtom was particularly large and most obnoxious I politely took it away from him, and Jack and I used it as a table for our gourds of kaffir beer, which we were pretending to consume in large quantities.

A gourd, however, is a top-heavy sort of drinking vessel, and in a very short time I had succeeded in spilling half a pint or so of my drink on the parchment of the drum. Not wishing to spoil the old gentleman's plaything, which he evidently valued above all things, I mopped up the beer with my handkerchief, and in doing so removed from the parchment a portion of the accumulated filth of ages.

"Hullo!" said Jack, taking the instrument from me and holding it up to the firelight. "There's a picture of some sort here. It looks like a man in a cocked hat."

He rubbed it hard with his pocket handkerchief, and the polishing brought more of the picture to light, till, plain enough in places and faded in others, there stood out, the portrait of a man in an old-fashioned naval uniform with stars on his breast, and underneath some letters in the form of a scroll.

"That's not native work," I exclaimed. "These are English letters," for I could distinctly make out the word "man" followed by a "t" and an "h." "Rub it hard, Jack."
