She felt much refreshed, and after dressing went and knocked upon Mrs. Montague's door to inquire if she had rested well, and if she could do anything for her.
There was no reply, and thinking perhaps she was still asleep, or had already arisen, she went up on deck to get a breath of air before going to breakfast.
"Why!" she exclaimed on looking around her, as she reached the deck, "how very wide the river must be just here; I did not observe it to be so when we came down; perhaps, though, we passed this point during the night, but I did not suppose we could get out of sight of land on the Mississippi."
A storm was evidently brewing; indeed, it was already beginning to rain, the wind blew, and the vessel rolled considerably.
Mona could see nothing of either Mrs. Montague or Louis, and found that she could not walk about to search for them, for all at once she began to feel strangely dizzy and faint.
"Can it be that I am going to be sick?" she murmured, "I was not coming down, for there was not much motion to the boat, but now it rolls and pitches as if it were out on the broad ocean."
She was growing rapidly worse, and, retreating to her stateroom, she crept again into her berth, and rang for the stewardess.
She was ill all that day—so ill that she could not think of much but her own feelings, although she did wonder now and then if Mrs. Montague was prostrated like herself. She must be, she thought, or she certainly would come to her.
Once she asked the stewardess if she was ill, and the woman had briefly replied that everybody was sick, and then hurried out to answer some other call.
But during the next day Mona began to rally, and the stewardess advised her to go up on deck, saying that the fresh air would do much toward improving her condition. She assisted her to dress, and helped her up stairs to a chair, covered her with a warm robe, and then left her alone.
