Question

The way a crow shook down on me the dust of snow from a hemlock tree has given my heart a change of mood and saved some part of a day i had rued.

Answer 1

"The way a crow shook down on me the dust of snow from a hemlock tree ... "

The narrator was standing under or near a hemlock tree in the winter time. A crow up on a branch of that tree shook some of the snow off and it landed on the narrator like a layer of dust.

"... has given my heart a change of mood ... "

The crow shaking snow on him has startled him/her or changed his/her mood somehow.

" ... and saved some part of a day I had rued."

The way this ends, it sounds like this person was in a foul mood (maybe because of the weather, even) and then a crow shook snow on him/her. This startled the narrator, probably making him/her laugh because of how random it was. The laughter changed the mood he/she was feeling and made at least part of a bad day feel better.
