Besides the misanthropic Christmas hater bent on cancelling Christmas, other details uncannily parallel How the Grinch Stole Christmas--first and foremost, there's the Seuss-esque word play and cadences (e.g., "Then the mothers arose in their just indignation And in with their tea took the whole situation," and "His eyes they were sunk, his coarse gray eyebrows under So far that the fact he could see was a wonder"). Then we have Santa Claus landing on the top of a mountain, a la the Grinch, "Preparing to slide down its side to the town Of Honey Hollow when night should come down." And there's the last minute rescue of the holiday and the change of heart on the part of the bad guy. Says Santa of the up-a-tree Mayor Neversmile: "But I'll venture to say, if he gets safely down, He'll be a changed person from this time and on, And never again will he seek to destroy The children's own birthright to Christmas and joy." No mention of whether or not Neversmile's heart grew several sizes that night.
It seems unlikely that Theodor Geisel was influenced by this poem, since it predates him by 24 years, but who knows? What we do know is that Seuss-sounding children's verse has been around for a hundred-plus years.
