The International Date Line is an imaginary line drawn through the Pacific Ocean irregularly, but trending generally in a north and south direction. The islands of the Pacific Ocean are separated in such a way that all those which lie to the east of it carry the same date as the United States, while all those on the west of it use the same date as Japan and Australia. Our map on pages 196 and 197 shows this date line.

The submarine cable connections that are marked with letters represent the telegraph cables that are owned and operated by sovereign states. Those that are marked with numbers represent telegraph cables that are owned and operated by private companies. The explanation of the names of the countries that the letters represent and of the names of the companies that the numbers stand for is subjoined:
