What is a stanza-by-stanza summary of the poem "The Brook" by Alfred Lord Tennyson?

In its initial stages, the brook rshes down the hills and
valleys, while chattering energetically.

The poet has used
words like "chatter", "bubble", "babble" etc. to highlight the playful child-like
attitude of the brook.

Both, the human life and the brook,
encounter and overcome obstacles, make a perilious journey in order to reach their
ultimate destination.The brook goes down to join the river and the human beings see the
end of the circle of life.

The brook crosses a number of
villages, hills, valleys etc., carries with it whatever comes in its way(fishes,
flowers, weeds, pebbles/stones) in order to reach where it has to. The human life works
in a similar fashion. The brook is full of fishes(graylings, trouts), an indication
oflife inside it. This is just like the human body that too can carry
life. 

In the final stages of its journey, the brook sobers
down, it is described with words like "steal", "slide", "murmur", "loiter", "linger"
etc.. The human life also in the later years shows similar signs. While the brook flows
eternally, the human life is limited to a fewnumber of years, it is
mortal.
