A Hamburgh vessel was lost near the bar before we came down. The men were much more regular in their habits than English sailors, so I had an opportunity of observing the fever acting as a slow poison. They felt "out of sorts" only, but gradually became pale, bloodless, and emaciated, then weaker and weaker, till at last they sank more like oxen bitten by tsetse than any disease I ever saw. The captain, a strong, robust young man, remained in perfect health for about three months, but was at last knocked down suddenly and made as helpless as a child by this terrible disease. He had imbibed a foolish prejudice against quinine, our sheet-anchor in the complaint. This is rather a professional subject, but I introduce it here in order to protest against the prejudice as almost entirely unfounded. Quinine is invaluable in fever, and never produces any unpleasant effects in any stage of the disease, IF EXHIBITED IN COMBINATION WITH AN APERIENT. The captain was saved by it, without his knowledge, and I was thankful that the mode of treatment, so efficacious among natives, promised so fair among Europeans.
After waiting about six weeks at this unhealthy spot, in which, however, by the kind attentions of Colonel Nunes and his nephew, I partially recovered from my tertian, H. M. brig "Frolic" arrived off Kilimane. As the village is twelve miles from the bar, and the weather was rough, she was at anchor ten days before we knew of her presence about seven miles from the entrance to the port. She brought abundant supplies for all my need, and 150 Pounds to pay my passage home, from my kind friend Mr. Thompson, the Society's agent at the Cape. The admiral at the Cape kindly sent an offer of a passage to the Mauritius, which I thankfully accepted. Sekwebu and one attendant alone remained with me now. He was very intelligent, and had been of the greatest service to me; indeed, but for his good sense, tact, and command of the language of the tribes through which we passed, I believe we should scarcely have succeeded in reaching the coast. I naturally felt grateful to him; and as his chief wished ALL my companions to go to England with me, and would probably be disappointed if none went, I thought it would be beneficial for him to see the effects of civilization, and report them to his countrymen; I wished also to make some return for his very important services. Others had petitioned to come, but I explained the danger of a change of climate and food, and with difficulty restrained them. The only one who now remained begged so hard to come on board ship that I greatly regretted that the expense prevented my acceding to his wish to visit England. I said to him, "You will die if you go to such a cold country as mine." "That is nothing," he reiterated; "let me die at your feet."
When we parted from our friends at Kilimane, the sea on the bar was frightful even to the seamen. This was the first time Sekwebu had seen the sea. Captain Peyton had sent two boats in case of accident. The waves were so high that, when the cutter was in one trough, and we in the pinnace in another, her mast was hid. We then mounted to the crest of the wave, rushed down the slope, and struck the water again with a blow which felt as if she had struck the bottom. Boats must be singularly well constructed to be able to stand these shocks. Three breakers swept over us. The men lift up their oars, and a wave comes sweeping over all, giving the impression that the boat is going down, but she only goes beneath the top of the wave, comes out on the other side, and swings down the slope, and a man bales out the water with a bucket. Poor Sekwebu looked at me when these terrible seas broke over, and said, "Is this the way you go? Is this the way you go?" I smiled and said, "Yes; don't you see it is?" and tried to encourage him. He was well acquainted with canoes, but never had seen aught like this. When we reached the ship--a fine, large brig of sixteen guns and a crew of one hundred and thirty--she was rolling so that we could see a part of her bottom. It was quite impossible for landsmen to catch the ropes and climb up, so a chair was sent down, and we were hoisted in as ladies usually are, and received so hearty an English welcome from Captain Peyton and all on board that I felt myself at once at home in every thing except my own mother tongue. I seemed to know the language perfectly, but the words I wanted would not come at my call. When I left England I had no intention of returning, and directed my attention earnestly to the languages of Africa, paying none to English composition. With the exception of a short interval in Angola, I had been three and a half years without speaking English, and this, with thirteen years of previous partial disuse of my native tongue, made me feel sadly at a loss on board the "Frolic".
