text: But, to return to the subject, let me tell you what delighted me in your letter. You have your words under control. You are not carried away by your language, or borne beyond the limits which you have determined upon. Many writers are tempted by the charm of some alluring phrase to some topic
  other than that which they had set themselves to discuss. But this has not been so in your case; all your words are compact, and suited to the subject, You say all that you wish, and you mean still more than you say. This is a proof of the importance of your subject matter, showing that your mind, as well as your words, contains nothing superfluous or bombastic.
