But when a fog descends, then it is that his face and manner change, and he who has been the most sociable and gayest of men suddenly becomes the most anxious and taciturn. His seat at the head of the table is vacant; look for him and you will not find him, as in fair weather, diverting groups of girls tucked up in steamer-chairs on the promenade-deck, but pacing the bridge and puffing a cigar which apparently has not been allowed to go out since it was lighted as the big ship backed from her wharf into the North River.
Wherever and whenever it occurs, fog is a source of danger from which neither prudence nor skill can guarantee immunity: and whether the ship is slowed down or going at full speed, there is cause for fear while this gray blindness baffles the eyes. With plenty of sea-room the danger is least, and it increases near land, especially where the coast is wild and broken, like that of Ireland and Wales, and where there are many vessels as well as rocks to be passed.
Probably the captain dreads but one thing more than a fog which comes down when he is making land. When he can see the familiar lights and promontories, he can verify the position of the ship and check his daily observations of the sun. Then it is plain sailing into port. But when the strongest light is quenched and every well-known landmark is hidden, and he has to feel his way with only the compass and the sounding machine to guide him, the consciousness that a slight divergence from the proper course may lead to disaster, keeps him on the pins and needles of anxiety, and sears his brain to constant wakefulness, as with a branding-iron.

The ship had swept down from the “nor’ard” like an arrow following the curve of its own bow, and it was promised that we should see land early in the afternoon and reach Queenstown soon after sundown. The weather could not have been better; it was clear and mild, and the air, the water, and the sky were tinged with the silvery pinks and grays which often appear, like mother-of-pearl, in the atmospheric effects of that southern coast. Flocks of birds were resting on the surface of the calm sea and wheeling around the ship, the gulls swinging within arm’s length of the passengers leaning against the rail. We steamed in among a fleet of fishing-boats with red sails—close enough to hear the greetings of the men, and these voices made the assurance of land doubly sure.
