Except in cases oi force majev/re, the water should never be drawn from the tanks on a voyage except for the purpose of chang- ing the water itself. Sometimes also the water outside the steamer is of a lower temperature than that in the tanks ; it is then advisable to pump a foot or two out and let in the fresh, and continue doing so until the temperature' in the tank is equal to the temperature of the sea.
To have means of determining the temperature of the cable at different heights of the ta...nk, Mr. Siemens has proposed to put a small coil of copper wire between the flakes ; the resistance of this coil at 75° Fahr. being exactly known, the existing temperature may be calculated by determining the actual resistance of the coil. Mr. Siemens' coil consists of silk-spun copper wire wound upon an 18-inch long iron rod, the whole coated with indiarubber, and cased in a metallic cylinder.
Shortly before paying out, a complete series of tests is taken, in the same way as before the coiling of the cable.
