We have noticed an error, which is very general, in the newspaper Marine lists, from Detroit to Buffalo. They all state, that the Steam boats, Henry Clay, Pioneer, and Niagara, clear at Detroit for Buffalo, when the fact is, they always clear at Detroit, for "Black Rock." The Clay and the Niagara, clear from this place for Detroit,-- the Pioneer sails from Black Rock and Buffalo, for Detroit. The editors who have committed these mistakes, are desired to look at the clearances, and "as they find, report."
The Steam Boat Henry Clay, having received the necessary repairs, will take her place in the line with the Superior, and perform her regular trip on Monday next. Her machinery has been throoughly overhauled, & she is in excellent condition to complete her engagements for the season.
The new Steam Boat William Penn, built at Erie, Pa. and owned by citizens at Erie, some in Chatauque county, and some in Buffalo, arrived yesterday at Buffalo. She is said to move handsomely, and is above 200 tons burthen. This makes the sixth steam boat in operation on Lake Erie.
