The dust of snow
Ans the poet mood changed when the snow of dust fall upon him .the poet was passing through the hemlock tree and there was a crow on that tree who dusted snow upon him and the poet starts feeling melodious .His spirit was revived and he got ready to utilised rest of the in some useful activities
Ans 2 the message is the whenever we go to the nature started feeling relax and happy .All our negative thoughts weep away .Even those things which we considered unauspicious become carrier of happiness
Am I right
Or if I am wrong then please correct me
Absolutely correct dear....😊
