intercommunication

In an almost ideal way, it has made intercommunication possible without travel.

As for organized systems of intercommunication, they were unknown even under the rule of a Pericles or a Caesar.

And how to develop a science of intercommunication, which commenced when the wild animals began to travel in herds and to protect themselves from their enemies by a language of danger-signals, and to democratize this science until the entire nation becomes self-conscious and able to act as one living being--that is the part of this universal problem which finally necessitated the invention of the telephone.

Such is the push of American life, that the humble immigrants from Southern Europe, before they have been here half a dozen years, have acquired the telephone habit and have linked on their small shops to the great wire network of intercommunication. In the one community of Brownsville, for example, settled several years ago by an overflow of Russian Jews from the East Side of New York, there are now as many telephones as in the kingdom of Greece.

But we often take, I think, an erroneous view of the probability of closely allied species invading each other's territory, when put into free intercommunication. Undoubtedly if one species has any advantage whatever over another, it will in a very brief time wholly or in part supplant it; but if both are equally well fitted for their own places in nature, both probably will hold their own places and keep separate for almost any length of time.

And it will, I believe, be universally found to be true, that wherever in two regions, let them be ever so distant, many closely allied or representative species occur, there will likewise be found some identical species, showing, in accordance with the foregoing view, that at some former period there has been intercommunication or migration between the two regions.
