From time to time, my friend Azorín attempts to analyse my ideas. I do
not pretend to be in the secret of the scales, as such an assumption
upon my part would be ridiculous. As the pilot takes advantage of a
favourable wind, and if it does not blow, of one that is unfavourable, I
do the same. The meteorologist is able to tell with mathematical
accuracy in his laboratory, after a glance at his instruments, not only
the direction of the prevailing wind, but the atmospheric pressure and
the degree of humidity as well. I am able only, however, to say with the
pilot: "I sail this way," and then make head as best I may.
