#195 The Spring Tide






The pre-
diction of
tides on an
a priori basis
is not possible.
Local conditions
apply. One works
from charts & tables—
how far the fall between
high & low, the positioning
of rocks, the shape of the sky.
What the weather is doing. Are
the Moon & Sun colinear with the
Earth? Do clouds collide with bells?
