All this time the frigate was steadily approaching, for if her course was to reach the town that slept so calmly in the sunshine, she would come within about half a mile of the rock as she passed.

The orders were given for the men to keep out of sight at the lower gun, the heavy piece being drawn back from the opening in the stone wall built up in front; and Roylance, who had charge there, lay down behind a piece of rock, where he could watch the vessel’s course.

Syd went on himself to the upper gun, after bidding the man at the flagstaff keep out of sight.

Terry was walking up and down impatiently as the lad approached, and the latter looked at him wonderingly, for only a short time before they had parted apparently the best of friends.

“Look here, Mr Belton,” said Terry, losing not a moment in developing his new grievance, “I want to know why Roylance has been sent down to the lower gun, where the work is of more importance than this.”

“More importance?” said Syd.

“Yes; I suppose you have been advised to do it as a slight upon me. You would not have done it of your own accord.”

“I was not advised to do anything of the kind,” said Syd, quietly; “I did what I thought was best. If there is any difference in the two posts, this is the more important, because every one would have to retreat here in case the lower gun was taken.”

“Surely I ought to know which is the more important, sir,” cried Terry, loudly, “and I see now it is a question of favouritism or friendliness. But I shall protest against it, and so I tell you.”

“There is no time to discuss such a matter as this now, Mr Terry,” said Syd. “You are to hold this gun in readiness to cover the retreat if the lower work becomes untenable; and now you must keep yourself and men hidden, and the gun drawn back.”
