e
weather having come, if it commences to fall again, the fine weather
will last a very short time, and _vice versa_.
5. In the spring and in the autumn, a sudden fall of the barometer
presages wind. In the summer, if the weather is very warm, it announces
a storm. In winter, after a frost of some duration, a rapid falling of
the barometrical column announces a change of wind, accompanied by a
thaw and rain; but a rising which happens during a frost which has
already lasted a certain time, prognosticates snow.
6. Rapid oscillations of the barometer should never be interpreted as
presaging dry or rainy weather of any duration. Those indications are
given exclusively by the rising or the falling which takes place in a
slow and continuous manner.
7. Toward the end of autumn, if after prolonged rainy and windy
weather, the barometer begins to rise, that rising announces the
passage of the wind to the north and the approach of the frost.
Such are the general consequences to draw from the indications of this
precious instrument.
Dick Sand knew all that perfectly well, as he had ascertained for
himself in different circumstances of his sailor's life, which made him
very skilful in putting himself on his guard against all contingencies.
Now, just toward the 20th of February, the oscillations of the
barometrical column began to preoccupy the young novice, who noted them
several times a day with much care. In fact, the barometer began to
fall in a slow and continuous manner, which presages rain; but, this
rain being delayed, Dick Sand concluded from that, that the bad weather
would last. That is what must happen.
But the rain was the wind, and in fact, at that date, the breeze
freshened so much that the air was displaced with a velocity of sixty
feet a second, say thirty-one miles an hour.
Dick Sand was obliged to take some precautions so as not to risk the
"Pilgrim's" masting and sails.
Already he had the royal, the fore-staff, and the flying-jib taken in,
and he resolved to do the same with the top-sail, then take in two
reefs in the top-sail.
This last operation must present certain difficulties with a crew of
little experience. Hesitation would not do, however, and no one
hesitated. Dick Sand, accompanied by Bat and Austin, climbed into the
rigging of the foremast, and succeeded, not without trouble, in taking
in the top-sail. In less threatening weather he would have left the two
yards on the mast, but
