FIRST-CLASS GUNNERS.
CARE AND PRESERVATION OF MINE MATERIAL.
Q. How are mine-cases preserved and cared for?
A. They are painted light gray on the outside, and the screw-threads covered with a mixture of lard-oil and white lead (4 parts of tallow to 1 white lead). They are also either painted or covered with protective material on the inside. They are then stored on suitable racks inside a "torpedo storehouse."
Q. How are all bearing surfaces, such as screw-threads, prepared for storage?
A. By first thoroughly cleaning them with brushes, kerosene, waste, etc., and then covering with the above mixture of white lead and tallow.
Q. How is the motor-generator cared for?
A. Fill all oil-holes, and keep all parts free from dust and foreign material; see that all connections are tight; see that all brushes are in good condition, and replace worn ones by new ones. Use very fine sandpaper for slight inequalities of the commutator.
Q. How are the mine-panel and the switchboard cared for?
