And by nineteen thirty-five,
Once the hunting was all done,
No more wolves were left alive.
Wolves were gone: each pack, each one.

Years went by in Yellowstone.
Sometimes, someone saw a track,
Just a footprint - all alone.
Might the wolves be coming back?

But not one gray wolf remained.
And by nineteen thirty-eight
Nearly every wolf was slain,
Gone in almost every state.
