Cecil Rhodes declared before a meeting of the British South Africa Company in the fall of 1892 that it was his ambition to link Cape Town and Cairo with an overland telegraph. The line would have both a commercial and political significance. England could be brought within quick and direct communication with her African possessions, and an impetus would be given to the growing commerce and trade of Africa by providing a cheap means of communication. Messages could be sent for about twenty-five cents per word, which

At that time about eighteen hundred miles of the line had already been built to accommodate existing needs, the greater part of this a mount being built northward from Cape Town. Since 1892, sixteen hundred miles of wire have been added along the northward stretch, of which nearly fourteen hundred miles are strung along the main line of the route. Southward from the other end of the continent about fifteen hundred miles more are to be found. Of the remaining nine hundred miles out of the originally proposed fifty-six hundred, four hundred and fifty will in all probability be spanned by wireless telegraphy, and there are between four hundred and fifty and five hundred more to be built before the scheme will be completed.
