Here also was picked up an interesting relic--a child's straw hat with a feather in it which when shown to Johnson (the survivor) was by him identified as worn by one of the children in the Tropics. We have heard that a piece of crochet-work with the needle stuck in it, and a reel of cotton attached, was picked up at North Harbour. This relic of the calamity seems as if it were only just laid aside by the fair fingers that but a few moments after must have been lifeless. The steamer after calling at Manly Beach and sending a boat up North Harbour (which however discovered nothing) stretched straight across for Watson's Bay and received on board the bodies of three men, evidently seamen by the marks on the arms--one, with the exception of the top of the scull, and the loss of part of the left arm, was entirely whole, and seemed to have been a fine man. The other two were only trunks, the mutilated remains of unfortunate sailors. Mr. P. Cohen of the Manly Beach Hotel reported that he saw two bodies floating and tried to recover them, but in consequence of the number of sharks, and the ferocity with which they fought for their prey, he was unable to do so. The steamer having thus closely searched every nook and corner, returned to Campbell's Wharf in the evening; leaving the bodies brought up to Sydney at the Dead-house for identification. Thousands of people in vehicles and on horseback, and an immense number on foot visited the heads during the day. The appearance of the Gap is described as having undergone a considerable change. Fragments of the wreck were fast disappearing, and the sea having greatly abated, several boats had approached close to the base of the fatal spot. An intrepid fellow named Mulhall, in his skiff ran down the coast to a considerable distance past the Semaphore, but without seeing indications of any survivors from the wreck. Nearly abreast of the Signal Staff several spars are to be seen, and as the sea recedes portions of sail became visible shewing that some part of the hull remains here. Part of a woman's apparel, marked J. Logan, was picked up near the body of some poor unfortunate in a sadly disfigured state. MONDAY, 24th. The principal item of news this morning connected herewith was a communication addressed by the Right Worshipful the Mayor, to the Editor of the _Sydney Morning Herald_, comprising the statement of Johnson, the sole survivor. This letter was to the following effect. [LETTER FROM THE MAYOR OF SYDNEY TO THE "SYDNEY MORNING HERALD."]
