It is an adventure book. The plan of Mr. Collins, which was submitted to the Western Union Telegraph Company of New York as early as 1863, seemed to be the most practicable of all the projects which were suggested for intercontinental communication. It proposed to unite the telegraphic systems of America and Russia by a line through British Columbia, Russian America, and north-eastern Siberia, meeting the Russian lines at the mouth of the Amur (ah-moor) River on the Asiatic coast, and forming one continuous girdle of wire nearly round the globe. This plan possessed many very obvious advantages. It called for no long cables. It provided for a line which would run everywhere overland, except for a short distance at Bering Strait, and which could be easily repaired when injured by accident or storm. It promised also to extend its line eventually down the Asiatic coast to Peking, and to develop a large and profitable business with China.
