Note 451 — Chapter XXII · THE TREASURES OF BRITAIN
Reading edition
The “big knife” was, we are told in the story, “a short broad dagger. When Arthur and his hosts came before a torrent, they would seek for a narrow place where they might pass the water, and would lay the sheathed dagger across the torrent, and it would form a bridge sufficient for the armies of the three islands of Britain, and of the three islands adjacent, with their spoil.”
