Impatient as he was to follow up the discovery that had been made, he realized that it would be very imprudent to expose his ship to possible danger when he had not steam enough to work her to the best advantage. He could only wait; but he was satisfied that he had done the best possible thing in changing the coal, for the black smoke would effectually blind the officers of the other vessel. They were not engaged in a chase, and the exciting question could be settled a few hours hence as well as at the present time.
"If the steamer ahead is the Scotian or the Arran, as I fully believe she is, probably her consort is somewhere in these waters," said the commander.
"Probably she lost sight of her in this fog," added Flint. "But, Captain Passford, we are in the face of something, though we do not yet know precisely what. I suppose you have your eye on Mr. Lillyworth?"
"I have kept him in sight all the time. He is on the quarter deck now, as he has been since all hands were called," replied Christy, who had not failed to look at him for a full minute since the discovery of the sail on the starboard. "He seems to be perplexed by the situation, and his time for action, if he intends to act, has not yet come."
"I don't see Pink Mulgrum anywhere about the deck."
"I saw him a few minutes since," added Christy. "He passed several times quite near Mr. Lillyworth, and very likely something was said between them; but they had no long talk."
Christy had charged Dave to watch Mulgrum if he went below, and to follow him up closely; but the deaf mute had been on deck most of the time. There was nothing that he could do, and nothing that the second lieutenant could do, to embarrass the operations of the ship while she remained at rest. The captain then descended to the deck, and personally looked into the condition of everything. In the course of his round he came to the quarter deck where the second lieutenant was stationed. He could see that he was nervous and uneasy about something, and it was not difficult to divine what perplexed him. He could hardly see the black smoke from the funnel of the steamer in the fog, for his place on the deck did not permit him to obtain as good a view of her as could be had from the bridge, and especially from aloft.
"Do you make out what that vessel is, Captain Passford?" asked Lillyworth, as Christy passed near him.
"Not yet, Mr. Lillyworth," replied the captain, not caring to converse with the conspirator.
"The fog does not seem to be very dense, and I should think the vessel might be made out from aloft," added the second lieutenant, evidently very anxious to know more about the sail ahead.
