At first the wind was in the northeast, and the "Albatross" had it

the deck without having their breath taken away by the rapidity of
the flight. And on one occasion they would have been blown overboard
if they had not been dashed up against the deck-house by the pressure

Four of them came aft, creeping along the deck.

Those who have been at sea, beating to windward in half a gale of
wind, will understand what the pressure was like. But here it was the
"Albatross" that by her incomparable speed made her own wind.

To allow Uncle Prudent and Phil Evans to get back to their cabin the
