King Solomon's Mines
what was the wording and source of Rider Haggards quote regarding King Solomon's Mines being just a story?
I'm writing a research essay involving King Solomon's Mines, The Coral Island and Robinson Crusoe. Somewhere along the line I remember reading that Haggard once wrote or said something to the effect of 'no need to bring psychology into it, it's just a children's story'. Unfortunately, I'm unable to find it in my notes, and half a hour of google searching has failed to reveal anything.
If I've remembered it right, could someone tell me what the wording was, and where he wrote/said it?
