simpler word, has remarkably altered our manner of living from what it was in the days of Abraham Lincoln. It has enabled us to be more social and cooperative. It has literally abolished the isolation of separate families, and has made us members of one great family. It has become so truly an organ of the social body that by telephone we now enter into contracts, give evidence, try lawsuits, make speeches, propose marriage, confer degrees, appeal to voters, and do almost everything else that is a matter of speech. In stores and hotels this wire traffic has grown to an almost bewildering extent, as these are the places where many interests meet. The hundred largest hotels in New York City have twenty-one thousand telephones--nearly as many as the continent of Africa and more than the kingdom of Spain. In an average year they send six million messages. The Waldorf-Astoria alone tops all residential buildings with eleven hundred and twenty telephones and five hundred thousand calls a year; while merely the Christmas Eve orders that flash into Marshall Field's store, or John Wanamaker's, have risen as high as the three thousand mark. Whether the telephone does most to concentrate population, or to scatter it, is a question that has not yet been examined. It is certainly true that it has made the skyscraper possible, and thus helped to create an absolutely new type of city, such as was never imagined even in the fairy tales of ancient nations. The skyscraper is ten years younger than the telephone. It is now generally seen to be the ideal building for business offices. It is one of the few types of architecture that may fairly be called American. And its efficiency is largely, if not mainly, due to the fact that its inhabitants may run errands by telephone as well as by elevator.
