The foregoing operations constitute the simple little matter of
setting a course. And the worst of it is that one must perform
every step correctly or else he will hear "Breakers ahead!" some
pleasant night, a nice sea-bath, and be given the delightful
diversion of fighting his way to the shore through a horde of man-
eating sharks.
Just as the compass is tricky and strives to fool the mariner by
pointing in all directions except north, so does that guide post of
the sky, the sun, persist in not being where it ought to be at a
given time. This carelessness of the sun is the cause of more
trouble--at least it caused trouble for me. To find out where one
is on the earth's surface, he must know, at precisely the same time,
where the sun is in the heavens. That is to say, the sun, which is
the timekeeper for men, doesn't run on time. When I discovered
this, I fell into deep gloom and all the Cosmos was filled with
doubt. Immutable laws, such as gravitation and the conservation of
energy, became wobbly, and I was prepared to witness their violation
at any moment and to remain unastonished. For see, if the compass
lied and the sun did not keep its engagements, why should not
objects lose their mutual attraction and why should not a few bushel
baskets of force be annihilated? Even perpetual motion became
possible, and I was in a frame of mind prone to purchase Keeley-
Motor stock from the first enterprising agent that landed on the
Snark's deck. And when I discovered that the earth really rotated
on its axis 366 times a year, while there were only 365 sunrises and
sunsets, I was ready to doubt my own identity.
