Excerpt from Telephony, Vol. 1 of 6: A Manual of the Design, Construction, and Operation of Telephone Exchanges
IT is veraciously reported that a quarter of a century ago, when a well-known New York capitalist was asked to invest in some Bell Telephone stock, he gave for his refusal the reason that the American District Telegraph boys were amply sufficient, and a Telephone enterprise would surely fail, as there was no room for an additional company in the business of transmitting messages. To day the A. D. T. Is a byword, while Telephony, ranking as one of the foremost of modern industries, bravely holds its own in the electrical quintet of the Telegraph, the Telephone, the Street Railway, Electric Lighting, and Power Transmission. As a factor in modern civilization it is a peer of any electrical industry, while from a finan cial standpoint it is, to say the least, a lusty third, with a strong probability that ere long it may lead the list.
