The data suggests, though, the unprovoked trend for Dirds to travel 
from essentially nowhere to no place. I suspect the observers may have 
erroneously bub consistently recorded the wrong direction of travel.^ if 
the compass directions relative to the course the ship had been on for the 
four days previous to the 15th had been used on the 15th, instead zzi&iz- 
ing the necessary adjustment, the above discrepancy would (and evidently 
did) occur. There was, in fact, a detectable movement between Kingman 
and Palmyra.
