p.2 We are already feeling the changes of the seasons, in the irregularities of our Mails. The Toronto Mail Steamer, the Princess Royal, which was due on Sunday morning at 6 o'clock, did not reach Kingston till some time of the night of Monday; we were not without alarm, fearing some accident had happened; we are glad to learn, however, that the gale alone prevented her, with all the other boats, from leaving Toronto, till Sunday evening.
We were misinformed as to the stoppage of the Navigation of the Lachine Canal, our informant meant to have said the Beauharnois Canal, we are happy however, to correct our error, and to add, that the interruption to the navigation of the latter even, was only for about a single day.
The greatest possible activity prevails amongst our local Forwarders here, some of whom are employed nearly all night as well as all day, in shipping produce to its respective destination, before the navigation closes.
The water of the Lake continues to fall; it is nearly two inches lower than when we last reported it. We are aware that it is subject to be influenced by the wind from various quarters, but we believe the above to be an average.
Launch of the Hon. John Hamilton's Iron Boat - The Launch of this beautiful Boat will take place from the yard of the Marine Railway tomorrow, Thursday, at 2 o'clock.
Reappearance of a Submerged Island In Lake Ontario - The Oswego Advertiser says that Gulf Island, situated about two miles from the Northern shore of Lake Ontario, between Port Hope and Cobourg, has re-appeared. It has been submerged seven years. A letter from Mr. William Osborn, jr., keeper of the light, dated August 31st, says that the rock for several yards around the lighthouse, is at least one foot above the water - that the lake is now lower than he has ever known it before. The fall of the water from December 1st, 1845, to March 24th, 1846, was nine inches; from March 24th to June 9th, 14 inches, and from June 9th to August 21st, 5 inches.
