Read the following extract, and answer the questions that follow:

I will arise and go now, and go to Innisfree, and a small cabin build there, of clay and wattles made; Nine bean rows will I have there, a hive for the honey-bee, and live alone in the bee-glade.

And I shall have some peace there, for peace comes dropping slow, Dropping from the veils of the moming to where the cricket sings; There midnight's all a glimmer, and noon a purple glow, And evening full of the linnet's wings.

a. What image has been used to describe peace?

b. What are the living creatures mentioned in the poem?
