Photo of Panama Canal workers tying lead rope to mule cable, taken 2 January 2000 by User:Stan Shebs
Tying the lead rope to the mule's wire cable. The mule will then operate its cable reels so that the cable is looped around an anchor point (such as a bitt) on the ship, then pull it tight in conjunction with a mule on the other side, so the ship is held firmly in the middle.
