Found Drowned. - The City Coroner held an Inquiry -on Saturday, at the Bayswater Hotel, Double Bay, respecting the death of a man named Robert Smail. William O. A Miller, coachman to the Hon. John Hay, of Rose Bay, stated that about 7 o'clock on Saturday morning he had occasion to go down to the water at Rose Bay, when he saw the body of a man lying face downwards on the sand in the water, about three feet from high water mark; the tide was going out at the time ; on examining the man he found life extinct ; the man was a stranger to him. Mrs Margaret Smaill, of Surry-street, Darlinghurst, identified the body as that of her husband, who was a carpenter by trade, and about 56 years of age ; the last time she saw him alive was about 4 o'clock on Friday afternoon; he was then sitting on the rocks by the windmill near his own residence; she had not seen him for three days previously; the last time she had any conversation with him was about five days previous to Friday; she then accused him of having been drinking, and he said he was very sorry for it; he had been away from home drinking for three weeks; she had on three or four occasions sued him for maintenance, and had obtained a magistrates order against him; about a fortnight ago he threatened to drown himself; he appeared quite sober when she saw him on Friday afternoon. Constable Michael Ryan, stationed at Rushcutter's Bay, believed he saw deceased walking along the road in the direction of Rose Bay, about 9 o'clock on Friday evening; he then appeared to be sober; when he took his body to the Bayswater Hotel, on Saturday morning he examined it, but found no marks of violence on it. Verdict : Found drowned, without any marks of violence appearing on the body, but how, or by what means, he became drowned there is no evidence to show.
