he _Olenia_ did not reply. He was
not prepared to deliver any long-distance explanation. Furthermore, the
yacht demanded all his attention just then. He gave his orders and she
forged ahead to round the whistler.

"Nor'west by west, half west, Billy. And cut it fine!"

The fog had fairly leaped upon them from the sea. The land-breeze
had been holding back the wall of vapor, damming it in a dun bank to
southward. The breeze had let go. The fog had seized its opportunity.

"Saturday Cove for us to-night, Mr. McGaw," said the master. "Keep your
eye over Billy's shoulder."

Then the secretary appeared again on the ladder. This time he did not
bring any "compliments."

"Mr. Marston wants you to report aft at once," he announced, brusquely.

Mayo hesitated a moment. They were driving into blankness which had shut
down with that smothering density which mariners call "a dungeon fog."
Saturday Cove's entrance was a distant and a small target. In spite of
steersman and mate, his was the sole responsibility.

"Will you please explain to Mr. Marston that I cannot leave the bridge?"

the first hired man who ever told Julius Marston to go bite his own
thumb."

"I may be a hired man," retorted Mayo. "But I am also a licensed
shipmaster. I must ask you to step down off the bridge."

"Does that go for all the rest of the--passengers?" asked the secretary,
angry in his turn. He dwelt on his last word. "It does--in a time like
this!"

"Very well, I'll give them that word aft."

Captain Mayo caught a side glance from Mate McGaw after a time.

"I have often wondered," remarked the mate to nobody in particular, "how
it is that so many damn fools get rich on shore."

Captain Mayo did not express any opinion on the subject. He clutched the
bridge rail and stared into the fog, and seemed to be having a lot of
trouble in choking b
