'The boats here were all too small to send to the wreck, and for which the wind was foul, with a fresh breeze. About 1 P.M. I started for Tunis, and arrived about 11 P.M. at the Goletta, where I landed, and sent to our Vice-Consul, who after some difficulty, owing to the port regulations, came to see me, and tried to pass me through the gates, but did not succeed. He promised to get two vessels ready, as unfortunately there were no steamers here at the time of our arrival. In one I meant to have sent Mr. Larcom to Galita, and the other I intended to take to the wreck. 'Friday, December 24th.--At daylight, when the gates opened, I entered a carriage, and drove up to our consul-general, who ordered his agent to forward my views in every way, sending his son to hurry matters, whilst he communicated with the Bey, who ordered his squadron to sea. 'Whilst my boat was preparing (a Maltese speronara, with a crew of twelve men, selected for their knowledge of the coast,) I wrote two letters, one to Malta, and the other to Lisbon, stating the loss of the ship. Not having slept for four nights, and being thoroughly tired, would account for the vague statement I sent. I then breakfasted, and started about two P.M., having put on board such provisions as my hurried departure admitted of--tea, coffee, biscuits, and spirits, in case I should be fortunate enough to save anybody. 'Saturday, December 25th, on my passage, and at daylight on Sunday I was close to the spot where the Avenger was wrecked, although there was no broken or discoloured water to mark it. I cruised about till satisfied she had either broken up or sunk. Whilst here I saw two steamers (Lavoisier and Pasha) come up and cruise about Galita together: a merchant ship, and a gun-boat of the Bey's, with which I communicated, asking them to take me to Galita, which I wished to examine personally, as also to speak the steamers, my own crew, with whom I had great trouble, refusing to do so. They declined, when I asked them to take half my crew out, and lend me two men, to which request I also received a negative; so I returned to Tunis, arriving at about 1 A.M. on the morning of Tuesday, December 28th. Sir Thomas Reade took all to his house, and made it a home for us. I went on board the French steamer Lavoisier, to thank the captain for his assistance, and also waited on the governor for the same purpose.' During the summer of the present year, the French government directed Captain Bouchet Riviere to make a survey of the Sorelle. In conclusion, therefore, we will give the following extract from that officer's letter, as it throws some light upon the circumstances which led to the loss of the Avenger:--
