Poem in John Henry Tudor's hand(?), March 1796, with empty envelope

This poem is about winter and appears to be an assemblage of passages from several published works along with Tudor's own compositions. On the verso, Tudor wrote "Abbott 2nd. March 1796." On the empty envelope is written: "Letters from my dear deceased friend J.H.T.," along with a note in another hand reading: "no letters found enclosed." It is unclear whether or not the envelope formerly held the poem.
