Magnetic Lines of Force Through Opening
The magnetic lines of force emanate from the inner circle of the opening as if they were an inner curtain. This accounts for the " drunkeness " or confusion so often observed by Arctic explorers as they approach the opening itself. They never understood why, of course. This phenomenon was described in our article Seven Days North of Tibet, which is the first article under " Arctic Proof " on the left. On page 216 of his book Farthest North Nansen described the confusion of the compass: " To give the course of the drift ( longitude ) is a difficult task in these latitudes as there is a perceptible deviation of the compass with every degree of longitude as one passes East or West."
