Widening the Telephone Horizon An Advertisement of the American Telephone and Telegraph Company IN THE memory of many now liv- 4 ing, Alexander Graham Bell made the apparently rash prediction that the day would come when we could talk to other countries, even across wide expanses of water. That was shortly after the historic conversation between Boston and Cambridge, a distance of two miles. Bell's vision was made a reality when in 1926 New York and London spoke together in two way conversation, and when in 1927 this service was opened to the public between any point in the U. S. A. and Great Britain. Since then, I Mexico has been brought into S speaking distance; important cities of continental Europe have come within the voice horizon of the United States. Even more important, the Bell Sys tem in the United States now embraces I8,500,ooo telephones-a growth for the past year of more than 750,000. We may now converse with each other from practically any point in this coun try to any other, and may talk beyond our borders and across the sea. That is measurable progress in widening America's telephone horizon.
