In most technical writings, of both governmental and private origin, the 

 suggestion of Whitney has been followed with varying fidelity during the last 

 forty-four years. It is clear that the inherent connotation of ' Cordilleras ' is 

 different from that of ' Cordillera.' The one emphasizes the compound nature 

 of the orographic unit; the other, the singular form of the word, emphasizes the 

 organic union of members. Hayden used both forms of the word. In recent 

 years there has been a rather widespread adoption of the term in the singular 

 number. In 1874, J. D. Dana proposed that the great mountain systems of 

 North America be referred to as the ' Western Cordillera ' and the ' Eastern 

 Cordillera,' the latter thus synonymous with what is now commonly called the 

 Appalachian system. Russell, in 1899, proposed ' Pacific Cordillera ' and 

 ' Atlantic Cordillera ' with respectively the same significance. Usage has.
