    The prevailing wind on the island is from south-west and the trees growing on the west side of the island have kept the shape of this wind even when it is no longer there. With the help of a compass, the direction and even the average speed of the prevailing wind can be assessed by measuring the extent to which these trees have been wind brushed.
