He explained his plan to the old salt, and then asked his opinion.
"You have aimed it too high, Mr.Passford," said the veteran, after he had squinted a long time along the piece.
"How is it otherwise ?" asked Christy.
"It is all right, sir; but the shot will pass over the steamer.

Drop the muzzle a trifle, and the shot will hull her, if you pull the lockstring at the right time." "I shall see that the string is pulled at the right time; thank you, Boxie," added Christy, without depressing the gun as the old man suggested, for he had a theory of his own which he intended to carry out.
"But the ship may change her position a trifle," added Boxie.
"Of course, I mean to sight the gun again at the very moment we fire," replied Christy, looking at his watch, though he was obliged to go into the engine-room to see what time it was.
It was after two, and the Vampire had had time enough to make the bend.
Christy wondered if Captain Carboneer was not looking for the four men he had promised to put on board of the old steamer; but some promises are better broken than kept, and the midshipman thought this was one of them, though he did not consider the present occasion as any excuse for lies, or the failure to keep his word, in the indefinite future.
The acting commander of the Bellevite--for such the middy was, and no one disputed his authority--began to be very nervous at the non-appearance of the enemy.

He was afraid that some mishap had befallen the Vampire; either that she had gone to the bottom or got aground, though he had heard Captain Carboneer say that he was a pilot for this part of the river.
Christy had mounted the gun carriage ready to take his final aim, and he had been there at least half an hour.

He was watching the point where the Roman candles had been planted, and he had perfect confidence in the judgment and fidelity of Mr.Watts.Boxie was stationed at the lock-string, and held it in his hand, ready to speed the great shot on its errand of destruction; but he hoped the midshipman would depress the muzzle of the gun before he was called upon to pull the string.

The other sailors who had served on board of the Bellevite, and had been drilled in handling the guns, were all in their stations, ready to load the piece again as quickly as possible after it had been discharged.
The silence had become intense and painful to all, for apart from the messenger of death and devastation which was about to be hurled at the Vampire, the Bellevite was in danger of being captured, and had a resolute enemy in front of her.
