Turning PALISADES; an invention of M. Coehorn, in order to preserve the palisades of the covert way from the besiegers shot. They are so ordered, that as many of them as stand in the length of a rod, or about ten feet, turn up and down like traps, so as not to be in sight of the enemy till they just bring on their attack; and yet are always ready to do the proper service of palisades.
