"Few persons realize the great value of reading aloud. Many of the foremost English stylists devoted a certain period regularly to this practise. Cardinal Newman read aloud each day a chapter from Cicero as a means of developing his ear for sentence-rhythm. Rufus Choate, in order to increase his command of language, and to avoid sinking into mere empty fluency, read aloud daily, during a large part of his life, a page or more from some great English author. As a writer has said, "The practise of storing the mind with choice passages from the best prose writers and poets, and thus flavoring it with the essence of good literatures, is one which is commended both by the best teachers and by the example of some of the most celebrated orators, who have adopted it with signal success."
