Letter box

CAMBRIDGE.- An extraordinary attempt was, made to blow up the letter-box of the Post-office, by means of gunpowder, but which happily failed. A student of Trinity-college, named Brane, was taken in the fact. Some suspicious circumstances had, for the last few days, induced the post-master to set a vigilant watch. About half-past eight in the evening, Brane was observed to be looking about him at the letter-box; he then applied a lighted cigar to a piece of paper which he held in his hand, and dropped a small paper parcel in the box; at this moment a policeman broke a pane of glass in the Post-office window as a signal, and the officers on the watch outside instantly secured him. There was about two ounces of powder in the parcel, which was folded up like a letter, but sewed at the ends, with a touch paper about nine inches long, communicating with the inside; a string was tied round the middle, with which he suspended it in the letter-hole while he was lighting the touch~paper.
