Can anyone help me, please?  In verse 2 of the above poem (p.795 of my 1940 Definitive Edition), RK speaks of conning "their task in a new-sown field" (the reference is to a mine-field) "with the Moonlight Sacrifice". (NB the capitals in those last two words).  What was the "Moonlight Sacrifice"? - 'Googling' those two words is no direct help, though it suggests that they may be pagan in origin - it talks about 'Wicca'.
