There is a story of one of King Arthur's knights - Sir Percival, I think - that once, riding through a forest, he found a lion fighting with a serpent. He drew his sword and helped the lion, for he thought it was the more natural beast of the two. To me Laputa was the lion, and Henriques the serpent; and though I had no good will to either, I was determined to spoil the serpent's game. He was after the rubies, as I had fancied; he had never been after anything else. He had found out about Arcoll's preparations, and had sent him a warning, hoping, no doubt, that, if Laputa's force was scattered on the Letaba, he would have a chance of getting off with the necklace in the confusion. If he succeeded, he would go over the Lebombo to Mozambique, and whatever happened afterwards in the rising would be no concern of Mr Henriques. I determined that he should fail; but how to manage it I could not see. Had I had a pistol, I think I would have shot him; but I had no weapon of any kind. I could not warn Laputa, for that would seal my own fate, even if I were believed. It was clear that Laputa must go to Dupree's Drift, for otherwise I could not escape; and it was equally clear that I must find the means of spoiling the Portugoose's game.

A shadow fell across the sunlight, and I looked up to see the man I was thinking of standing before me. He had a cigarette in his mouth, and his hands in the pockets of his riding- breeches. He stood eyeing me with a curious smile on his face.

'Well, Mr Storekeeper,' he said, 'you and I have met before under pleasanter circumstances.'

I said nothing, my mind being busy with what to do at the drift.

'We were shipmates, if I am not mistaken,' he said. 'I dare say you found it nicer work smoking on the after-deck than lying here in the sun.'

Still I said nothing. If the man had come to mock me, he would get no change out of David Crawfurd.

'Tut, tut, don't be sulky. You have no quarrel with me. Between ourselves,' and he dropped his voice, 'I tried to save you; but you had seen rather too much to be safe. What devil prompted you to steal a horse and go to the cave? I don't blame you for overhearing us; but if you had had the sense of a louse you would have gone off to the Berg with your news. By the way, how did you manage it? A cellar, I suppose. Our friend Laputa was a fool not to take better precautions; but I must say you acted the drunkard pretty well.'

The vanity of 19 is an incalculable thing. I rose to the fly.
