Sounds like the interview with Bevington specifically touched on the topic of rings of fire.
Not that recall. I just don't remember hims saying anything about fire rings. It has been a long time since i reviewed the video.
How did he account for Maude's reports explaining the use of fire rings to keep away crabs?
He didn't.
Also, curious to a snapshot of Bevingtons demeanor and overall impression of how the interveiw went.
Eric Bevington was what Rudyard Kipling had in mind when he wrote "....send forth the best ye breed." They don't make 'em like Eric anymore. Even in his 80s he was tall, handsome, distinguished, kind and totally devoted to the subjects of the Empire whom he had served for most his adult life. When I spent a couple days with him at his home in the south of England in 1990 he was preparing for a trip to Tarawa to visit old friends. We compared notes about Nikumaroro and I complained that getting ashore always involved getting your feet wet. He said, "No, no you're doing it wrong. You have the boys carry you ashore."
Were the maps detailed or of the hand-drawn variety?
I brought a large photocopy of a detailed map which he marked. He didn't have any maps.
There are teeming millions of us [or at least hundreds : )] willing to donate our time and equipment to transfer those interviews to digital format! In the meantime, can members view the oringinal video in the TIGHAR library's reading room? 
If we had a reading room I wouldn't risk the old tape. We'll play it once to digitize it.
