These live holesextend through the whole thickness of the clamp, andare filled with faggots, which, being lighted from theoutside, soon ignite the adjacent breeze. As soon a^the clamp is fairly lighted, the mouths of the live holesare stopped, and the clamp burns until the whole of thebreeze is consumed, which takes from three to sixweeks.
