Canada for burning not only cities on the lakes, but others; and it is very necessary that great precaution and vigilance should be observed everywhere. I have the assurance that Creek fire is being prepared in Windsor. Buffalo, Cleveland, an this city will be the principal cities to be burned, and there will be armed attempts to rob and plunder; Cincinnati and Louisville are also mentioned. I am also informed that by some means a large number of rebel soldiers have been introduced into Canada; some, it is said, have been furloughed, and have made their wy through the lines, I have at this time very excellent means of obtaining information, and the only apprehension I have is that the persons in my employ may fail at the last moment. In this city I have called the attention of the hotel keepers to the necessity of observing great vigilance in regard to their guests, and the hotels are daily visited by a secret agent in my employ.

I am, captain, very respectfully, your obedient servant,

B. H. HILL,
