1) Yes. In this case it's called an end rhyme, because the last word in the second line rhymes with the last word in the forth line. 2) I would say that the words are not out of order. They are just presented in a poetic way, because the poet wants to create a rhyme, or she wants you to feel certain emotions in a particular order. Poets play with words and the structure of sentences, that's what makes them poets. 3) and 4) This poem is by Emily Dickenson. I found this on the internet... "Dickinson most often punctuated her poems with dashes, rather than the more expected array of periods, commas, and other punctuation marks. She also capitalized interior words, not just words at the beginning of a line. Her reasons are not entirely clear. Both the use of dashes and the use of capitals to stress and personify common nouns were condoned by the grammar text (William Harvey Wells’ Grammar of the English Language) that Mount Holyoke Female Seminary adopted and that Dickinson undoubtedly studied to prepare herself for entrance to that school. In addition, the dash was liberally used by many writers, as correspondence from the mid-nineteenth-century demonstrates. While Dickinson was far from the only person to employ it, she may have been the only poet to depend upon it. While Dickinson’s dashes often stand in for more varied punctuation, at other times they serve as bridges between sections of the poem—bridges that are not otherwise readily apparent. Dickinson may also have intended for the dashes to indicate pauses when reading the poem aloud." https://tinyurl.com/yxf4n6do

1. Yes. It is common to use unusual word orders in English poetry for several reasons. One reason is for the rhyme. 2. In English, it takes practice and familiarity to make sense out of unfamiliar word orders. 3. The poet here, Emily Dickinson, frequently uses dashes like that. It is an unusual thing, and I don’t know why she used them so much. I don’t think it affects the meaning of the poem. 4. I don’t know why she capitalized those words. In some archaic English and the related language German, there was a tendency to capitalize certain nouns — a tendency that no longer exists in English. Maybe she was trying for a bit of an archaic feeling. Or, maybe it’s just Dickinson being her strange self.
