After Livingstone had been six weeks at Quilimane, H.M. brig "Frolic" arrived, with ample supplies for all his need, and took him to the Mauritius, where he arrived on 12th August, 1856. It was during this voyage that the lamentable insanity and suicide of his native attendant Sekwebu occurred, of which we have an account in the _Missionary Travels_. At the Mauritius he was the guest of General Hay, from whom he received the greatest kindness, and so rapid was his recovery from an affection of the spleen which his numerous fevers had bequeathed, that before he left the island he wrote to Commodore Trotter and other friends that he was perfectly well, and "quite ready to go back to Africa again." This, however, was not to be just yet. In November he sailed through the Red Sea, on the homeward route. He had expected to land at Southampton, and there Mrs. Livingstone and other friends had gone to welcome him. But the perils of travel were not yet over. A serious accident befell the ship, which might have been followed by fatal results but for that good Providence that held the life of Livingstone so carefully. Writing to Mrs. Livingstone from the Bay of Tunis (27th November, 1856), he says: "We had very rough weather after leaving Malta, and yesterday at midday the shaft of the engine--an enormous mass of malleable iron--broke with a sort of oblique fracture, evidently from the terrific strains which the tremendous seas inflicted as they thumped and tossed this gigantic vessel like a plaything. We were near the island called Zembra, which is in sight of the Bay of Tunis. The wind, which had been a full gale ahead when we did not require it, now fell to a dead calm, and a current was drifting our gallant ship, with her sails flapping all helplessly, against the rocks; the boats were provisioned, watered, and armed, the number each was to carry arranged (the women and children to go in first, of course), when most providentially a wind sprung up and carried us out of danger into the Bay of Tunis, where I now write. The whole affair was managed by Captain Powell most admirably. He was assisted by two gentlemen whom we all admire--Captain Tregear of the same Company, and Lieutenant Chimnis of the Royal Navy, and though they and the sailors knew that the vessel was so near destruction as to render it certain that we should scarcely clear her in the boats before the swell would have overwhelmed her, all was managed so quietly that none of us passengers knew much about it. Though we saw the preparation, no alarm spread among us. The Company will do everything in their power to forward us quickly and safely. I'm only sorry for your sake, but patience is a great virtue, you know. Captain Tregear has been six years away from his family, I only four and a half."
