service, sprang into existence, and the present total length of 
the submarine cables of the world is, in round numbers, 160,000 
nautical miles, or enough to girdle the earth seven and one-half 
times at the equator. At an average cost of SI, 200 per mile, the 
entire system represents an outlay of $192,000,000. Of the total 
mileage about one-eighth is under the control of various national 
governments. 
The Hydrographic Office issued, in 1892, a book on Sub- 
marine Cables,” prepared by Mr G. W. Littlehales as a part of 
the report of that Office on the survey made by the U. S. shij)S 
Albatross and Thetis for an ocean cable route between San Fran- 
cisco and Honolulu. It contains a large amount of interesting 
infonnation, including valuable statistical data, among which is 
a complete list of the Submarine' Cables of the world, in detail. 
The tallies being much too voluminous for publication in these 
pages, the following list of the more important cables has been 
compiled from them, the reader being referred to the original
