But Tom was counting without his host, for at that instant the ship, giving another roll, threw him once more against the luckless lieutenant, who grasping at the corporal, over they all went, McTavish and Gerald, who had been thrown against the other jollies, bringing them again right over Lieutenant Jennings to the deck. "This is unbearable," he spluttered out, "I'll have you youngsters put under arrest. Marines, can't you keep your legs? Help me up. Get off me, all you, I say." But as the marines could not help themselves, it could scarcely be expected that they could assist their officer, still less could the medico and the midshipmen. The serjeant, however, hearing the uproar, followed by a couple of his men, with a faint idea that a mutiny of some sort had broken out, hurried aft, and with the assistance of Higson amid the other oldsters who came out of the berth to see what was the matter, quickly got the mass of struggling humanity disentangled and placed in as upright position as circumstances would allow. The lieutenant ought really to have been much obliged to Tom, for his anger completely overcame the nausea from which he had been suffering; but ungrateful, like too many others, as Higson observed, he went back into the gunroom demanding condign punishment on the head of his benefactor and his messmates. He was saved thereby from witnessing the effect of that leveller of mankind, sea-sickness, on nearly half his men, who lay about the deck unable to move, and only wishing that the ship would go down and bring their misery to an end. Jack soon soothed the temper of his brother officer, who was a brave and really a good-natured man, and then went to look after Tom and Gerald. He advised them to lie down with their eyes shut in the berth which was now vacated, the occupants being called off to their respective duties, and the assistant-surgeon having retired into the dispensary to concoct a specific against sea-sickness of his own invention, which made him and those he persuaded to take it ten times worse.
