About twelve oeclock this day, being in the Lower Town, I looked up at the signal-gun by the flag-staff on Cape Diamond, and saw a soldier up in the heavens there making preparations to fire it, - both he and the gun in bold relief against the sky. Soon after, being warned by the boom of the gun to look up again, there was only the cannon in the sky, the smoke just blowing away from it, as if the soldier, having touched it off, had concealed himself for effect, leaving the sound to echo grandly from shore to shore, and far up and down the river.
