"How to Speak and Write Correctly" by Joseph Devlin

[K_D]

Hi,
If some teachers could share their opinions about the book "How to Speak and Write Correctly" by Joseph Devlin. Once I have read and listend a few chapters from librivox recording and I liked it. Do you think it is a good book to use for learning English 100 years later after it was written?

Thank you.

Many things will have changed, but that doesn't mean that an old book is worthless.
