Stars Sliding

The stars are sliding wanton through trees,
The sky is sliding steady over all.
Great Bear to Gemini will lose his place
And Cygnus over world's brink slip + fall.
Follow-my-Leader's not so bad a game.
But were it leap frog: O to see the shoots
And tracks of glory; Scorpions and Swans tame
And Argo swarmed with Bulls and other brutes.
