How does George Eliot use imagery in The Mill on the Floss?

Imagery:

“Life seems to go on without effort when I am filled with music.”

“We could never have loved the earth so well if we had had no childhood in it, if it were not the earth where the same flowers come up again every spring that we used to gather with our tiny fingers as we sat lisping to ourselves on the grass, the same hips and haws on the autumn hedgerows, the same redbreasts that we used to call ‘God’s birds’ because they did no harm to the precious crops. What novelty is worth that sweet monotony where everything is known and loved because it is known?”

“Nature repairs her ravages, but not all. The uptorn trees are not rooted again; the parted hills are left scarred; if there is a new growth, the trees are not the same as the old, and the hills underneath their green vesture bear the marks of the past rending. To the eyes that have dwelt on the past, there is no thorough repair.”
