An American packet brings newspapers from New York, dated the
10th of March. The malecontents on the Canadian frontier continued to give trouble to the British in Upper Canada, and the American militia in New York and Michigan. Two incursions had been made into Canada ; and on one of these there was a little fighting, between the invaders under MACKENZIE and the British troops. According to the accounts, the former exhibited more discretion than valour, and soon fled; leaving between thirty and forty prisoners in the hands of the Loyalists. It ex- cited an uncomfortable feeling, to discover among the prisoner' some residents of Upper Canada, who had been looked upon u prudent and loyal men of substance.
Sir JOHN COLBORNE had assumed the government of Lower Canada, and issued a proclamation continuing martial law in the district of Montreal, in consequence of its disturbed condition. The Earl of GOSFORD had arrived at Boston, on his route to England; and Sir GEORGE ARTHUR at New York, on his road to Toronto. Sir ALLAN M'N ye may soon be expected in this country. He comes to tell Lord GLENELG bow affairs really stand in Upper Canada, and to propose his Orange nostrums for putting matters in good order.
