“This is, indeed, a serious matter,” I observed; “and I am grateful to you, Potto, for telling me. At the same time, however, bad as Ali’s intentions may be, I really do not think we have much cause for alarm. Still, I am sure the captain also will be grateful to you for the warning you give him; but I am afraid he will be very much annoyed when he hears of it. I think I must first tell Mr Thudicumb, and he can arrange the best way of letting the captain know.”

“Dat’s it, Massa Walter. Tell de first officer. He wise man. He no put out by dis or any oder matter. I now go forward, lest Ali come on deck, or any of his people, and see me talking to you.”

“Do so,” I said; “but, Potto, I think you will assist us if you would pretend to be more ready to listen to what Ali has to say to you, and you can give me information of his plans.”

Potto did not answer immediately.

“I not certain dat Ali speak de truth to me,” he answered. “At first he did; but he big, cunning rogue, and he suspect dat I no love his plans. Still, Massa Walter, I do as you wish, dough Potto Jumbo no like to act spy over any one, even big rascal like Ali. Potto Jumbo once prince in his own country, before de enemies of his people came and burnt his village, and kill his fader, and moder, and broders, and sisters, and carry off him and all dey did leave alive on board de slave-ship. Den de British cruiser take her, and Potto Jumbo enter on board de man-of-war, and dere became boy to de cook, and now Potto Jumbo is cook hisself on board de Bussorah Merchant. Dere, Massa Walter, you have my history. You see I do not wish to do anything derogatory to my family and my rank;” and Potto Jumbo drew himself up, as if he was again the monarch of half-a-dozen bamboo-built cottages, and their unclothed, dark-skinned inhabitants. “Now, good-night, Massa Walter, again; I go forward.”

Potto Jumbo glided away to the fore-peak, and I walked aft. I had, however, some little time to wait before my watch was over. I then hurried into the first mate’s cabin. He was about to leave it to take charge of the deck.

“Will you let me have a word with you, sir,” I said, “before you leave the cabin. I have something somewhat unpleasant to communicate, and I do not like to delay doing so.”

“Let me have it out then at once, Walter,” he said. “Nothing like the present moment; and, for my part, I always like to know the worst, if I can get at it.”

I at once told him in a low voice the information I had received from Potto Jumbo. The light of the lamp in his cabin fell on his weather-beaten countenance, but I saw no change in it.

“Very likely,” he observed; “that serang has a hang-dog look, which shows that he is capable of attempting any atrocity; but I do not think he will succeed notwithstanding. I will tell the captain in the morning, but there is no necessity to do so now. For his own sake, he will not set the ship on fire, or scuttle her, at this distance from land; and as to his hope of overpowering us, or the English part of the crew, the idea is absurd. However, I will warn the other officers. You go and tell Mr Tarbox I wish to speak to him. Take care the Lascar fellows do not see you; and then go back to your berth and turn in.”
