NEW YORK. Dec. 12.

Extract of a letter from Canandaigua, dated December 4.

"We are informed by a gentleman volunteer, who joined the army to assist in the invasion of Canada, that a body of sailors and others, in number about 300, went into Canada, took two small batteries, spiked the cannon, and took about 30 prisoners. The whole army have been two or three times in battle array, and ready to cross the Niagara, and as often ordered to return to camp."

Extract of a letter from a gentleman at Buffalo, to his friend in this city, dated Nov. 28, 1812.

"This morning between 2 and three o'clock, about 150 soldiers and 100 seamen, crossed over from Black Rock stormed the enemy's batteries, spiked the guns, and took between 30 and 40 prisoners. The other troops were drawn up and embarked at the Navy Yard, and ascended the river to the Rock, in full expectation of crossing to the Canadian shore, without the loss of a single man, when, from some reason, a flag was sent over by Gen. Smyth, & the troops ordered to disembark & return to their encampment I trust the General can satisfy the public for his conduct, as many volunteers from this part of the state, had marched a great distance through bad roads, on account of his address to them, in order to cross the river without any constitutional objections. There are still flocking in from every quarter, but whether any thing will be done, it is impossible for me to say. Many have determined to stay and assist in the conquest of Canada, and others have become lukewarm and dissatisfied. Judging from appearances, I think it would have been a glorious day to the American arms, and have retrieved our honor, had the attempt been made: but those in higher military standing know best."

N. B. The letter from which the above is extracted, bears the Buffalo post mark of the 30th of November; of course nothing more had been attempted at that date.
