On the 11th of July, all being completed, she once more stood out of Table Bay, with the cheers and hearty good wishes of all for her success, although they wondered what her mysterious destination could be. It is evident that a steamer bound to Singapore, or to any place still further eastward, would have a choice of three routes; either she might make her passage from the Cape towards the Straits of Sunda, between the islands of Java and Sumatra, trusting principally to her sails, the winds being generally strong in those latitudes, and thereby saving her fuel; or she might run from the Cape up to the Mauritius, to take in coal, which has been done by many steamers, and thence proceed by the Straits of Malacca; or, lastly, she might run through the Mozambique Channel, between the continent of Africa and the island of Madagascar, and, touching at Ceylon for coals, proceed likewise down the Straits of Malacca to her destination. On the present occasion, the Nemesis had distinct orders to choose the latter route, the season of the year being considered the most favourable for it, and it being thought desirable that a visit should be paid to the island of Johanna, the most frequented of the group called the Comoro Islands, situated at the northern end of the Mozambique Channel. This island will be more particularly alluded to in its proper place. Thence she was to proceed direct to Ceylon for coals. But even this was only known to her commander; and all that either officers or men could learn about her destination, when they left the Cape, was, that they were at once to proceed through the Mozambique Channel, but with what object they knew not. The Nemesis now approaches to one of the most eventful periods of her history. Six days had scarcely passed since her departure from the Cape, when a new and quite unforeseen danger awaited her, and threatened the most appalling consequences, without any port being at hand for refuge. It has very rarely happened that a ship has been so near destruction, and yet escaped at last. The first few days of her passage alternated between gales and calms, and the high sea which she encountered only gave her a further opportunity of proving the good qualities which she possessed as a sea-boat. Cape Francis, on the southern side of the coast of Africa, within the colony, near Algoa Bay, was in sight from the mast-head on the 14th. The barometer began to fall on the 15th, and at length, on the following day, had almost sunk to twenty-eight inches. Vivid flashes of lightning now ran along the sky to the westward; the wind, which had been strong and steady from the N.N.W., freshened to a heavy gale; every appearance threatened an increase rather than a diminution of the storm; and the sea became so high and heavy, that it threatened every moment to overwhelm the _long_, _low_ Nemesis, for the sail that could be put upon her scarcely sufficed to keep her before the sea.
