Ronald was not quite so sure of that, and he suspected that Dicky himself, if put to the test, might change his mind.

The stranger in a short time drew near enough to see the signals which the “Thisbe” began to make. Her answers were watched for with intense interest on board both ships. Mr Calder had his signal-book open on deck.

“There goes up the stranger’s bunting,” he exclaimed; “now we shall see what he has got to say for himself.” Again and again his glass was at his eye: at length he shut it up with a loud slap.

“I thought as much,” he added; “he’s a Frenchman; but he will find the ‘Concorde’ a tough morsel if he attempts to swallow her, after she has belonged to us.”

Captain Courtney arrived before long at the same conclusion, and ordered the prize to stand to the northward, under all the sail she could carry.

Tom Calder received the order with a very bad grace. “I thought that he would at least have let us stop to help him to fight it out,” he muttered to himself as he put his hand to his mouth to issue the necessary orders to his scanty crew.

Sail was made on the prize, while the “Thisbe” hauled up her courses, and stood slowly after her to draw the enemy more away from the land before the commencement of their expected contest.

Mr Calder felt that he had no right to question his commander’s judgment; he could not help seeing, also, that could he effect his escape, he might possibly fall in with another British cruiser, and send her to the “Thisbe’s” assistance.

Even with more intense interest than at first, the approach of the stranger was watched from the deck of the “Concorde.”

The prize had got a mile from the “Thisbe” when the French surgeon made his appearance on deck, to enjoy a mouthful of fresh air, after his fatiguing duties below. His eager glance, and the sudden lighting up of his eye, showed that he fully comprehended the state of affairs.
