The Steam Boat CYNTHIA Burnt. -- On Saturday last the Steam Boat CYNTHIA, commanded by Capt. J. H. Hodson, when two miles this side of Amherstburgh, on her way to sandwich, was discovered to be on fire. So rapidly did the flames spread over the upper works, that it was deemed expedient to run her on shore immediately, in order to save the lives of those on board, which was accordingly done. It is not yet known how the fire originated, but it is supposed to have been owing to the very high wind at the time, communicating a few sparks on the opening of the furnace, to add more fuel. We regret to add that Sherrif Lachlan, who was on his way to this town to attend the Court of Quarter Sessions which meets this day, lost a box containing many valuable public and private papers, which in the alarm of the moment was unfortunately left on board.
The CYNTHIA was a small boat, and had been plying daily between Windsor and Amherstburgh, since the opening of navigation, the loss of which will prove a serious inconvenience to the inhabitants of both places, especially at this season, when the autumnal rains are likely to render the river road utterly impassable. She was owned by Duncan McGregor, Esq., of Chatham, whose loss is estimated at three thousand dollars.
