PREVENTION OF SHIPWRECKS.

to light up dangerous coasts with beacons visible at a great distance out
at sea, to point out shoals by means of landmarks and buoys, and to communicate with mariners by means of the telegraphy of semaphores; and,
above all, a precise knowledge of the movements of the atmosphere, enabling one to form an increasingly clear prevision of the phenomena of
the weather, are the means by which disasters at sea may be best prevented. Navigation, especially steam navigation, which enjoys the immense privilege of speed, will have but very few dangers to fear when
mariners understand the art of manoeuvring in order to avoid tempests,
and every vessel has become a floating observatory, as suggested by
Maury, the illustrious American sailor.

At every period of history men have made it their business to endeavor to foretell the weather. Owing to the numerous advantages
which are offered us by civilization, the practical utility of knowing beforehand any approaching meteorological changes has become less urgent, because in the present day we can to some extent shelter ourselves
from the influence of these variations by our clothing, our dwellings,' and
our food. There are even some people who, by means of an altogether
artificial mode of life, have arrived at the point of being unacquainted
with the greater part of the meteoric agencies of the air. This was not
the case with the nations of antiquity. Living in the open air or in ill-
closed huts, seeking their livelihood in hunting, fishing, agriculture, or in
'rearing cattle, they were compelled incessantly to search the horizon in
order to discover the earliest antecedent signs of wind, storm, and rain.
By a constant examination of the heavens, the most skillful observers
were enabled to discover either more or less accurately a "great number
of facts which placed them in a position to foretell the weather; especially in countries where the phenomena of the atmosphere took place with
some degree of regularity, as in Egypt and the Indies, those who were
called " wise men," on account of their knowledge of times and seasons,
learned to make fortunate prognostications as to the approaching changes
of temperature which were not indicated to the common herd by any out-
