At the same time a man is sent over the side of the planter near the mine davit (a rope ladder may be used) to secure the hook of the differential block in the sling attached to the maneuvering ring of the mine when it comes to the surface. To bring the mine to the proper place to accomplish this, a man should be ready to secure the mine-buoy rope with a boathook; other men should be ready to pull the mine forward, if necessary, by means of the cable. The mine is raised by the differential block of the mine davit. It may be raised by the boom and fall; or by means of a tackle secured to the mine davit, the end of the rope running through a snatchblock to the drum of a windlass. The distance weight of the automatic anchor may be raised by the fall of the boom, or by an improvised tackle. An eye should be made in the distance rope for this purpose. If the end of the cable is lost, the work may proceed as follows: The planter moves out to the mine if its buoy is still in place. A sling made of raising rope may be thrown over the mine, or two raising ropes are tied together and one end is passed to a launch which moves around the mine and brings the end back to the planter. Both ends are placed over the cathead, through a snatchblock, and around the drum of a hoisting windlass. The mine is hoisted, bail up, until near the cathead. It can then be transferred to the anchor davit. The mine cable is pulled in until the raising rope is reached. The work then proceeds as before. If the mine buoy has been removed, a yawl may drag for the cable with a grappling iron. If the raising rope should break or be lost, the mine may be raised as mentioned above, except that the mine must be transferred to the fall of the boom and the anchor raised by means of its mooring rope, or the mine may be transferred to the anchor davit, as before, and a raising rope made fast to the mooring rope of the anchor and carried over the cathead, through a snatchblock, to a hoisting windlass. The mine, as soon as the strain is taken up by the raising rope, is unshackled. The anchor is then taken aboard in the usual manner. As soon as the mines are taken aboard they are disconnected, the ropes are coiled, and all matériel placed so as not to interfere with subsequent work. As soon as the matériel is unloaded on the wharf it should be cleaned thoroughly and stored. If the multiple cable is to be left down, the ends of the conductors are insulated, the lid replaced, and the box lowered by means of a raising rope, the end of which is made fast to the bight of the bowline of the anchor rope. If the multiple cable is to be taken up, the end is passed to the planter, run through a large snatchblock on the bow, and coiled on a cable-reel as it is raised. Whenever a multiple cable is coiled on a reel it should be secured so that both ends will be available for test when the cable is stored.
