Analysis of Imitators

A boat came in; the cliff was baked;
The noisy boat-chain fell and clanked on
The sand-an iron rattle-snake,
A rattling rust among the plankton.

And two got out; and from the cliff
I felt like calling down, 'Forgive me,
But would you kindly throw yourselves
Apart or else into the river?

Your miming is without a fault-
Of course the seeker finds the fancied-
But stop this playing with the boat!
Your model on the cliff resents it.'
