The Snows They Melt the Soonest

Sadly, Erica Smith proved unable to spell my name correctly, but such laziness is not uncommon. Otherwise it was an adequate, though incomplete and poorly edited, summary of information that appeared in several postings in the Mudcat thread Origins: The Snows They Melt the Soonest. There is no summary here; just the original discussion, of which only a small part is to the point.

I don't think that the relevant volume of Blackwood's Magazine is available online (though later volumes are), so if you want to read the whole thing you'll probably have to find a library copy. I was only able to transcribe the passage relevant to the song in question, having but a blunt and borrowed pencil to hand. The whole of that passage, though, is quoted in the thread indicated.
