一去不返

From the Gulf to Canada , and from western Kansas and Nebraska to the Sierras , the cattle round-up and the mess wagon followed close on the disappearing Indian and buffalo .

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
