How to Speak and Write Correctly by Joseph Devlin

This is a 1910 guide for those who wish to learn how to correctly (though maybe not "properly") create sentences, use figures of speech, write letters, and more, all while choosing the right words and doing it with style. Joseph Devlin's words may not all be relevant still today, but at least it sounds good when it's read aloud! (Summary by Andrew Lebrun)
