She knew not, guessed not why, when she laid her head on her pillow that night, she wept so bitterly.

The source of those secret and silent tears she could not trace, she only knew their cause was one of sorrow, and yet she loved Mary.
The pleading earnestness of Emmeline had, after some little difficulty, obtained the consent of her mother to her accompanying her father and brother, on condition, however, of her not agitating Mary by any unconstrained display of sorrow.

It was only at their first meeting this condition had been forgotten.

Mary looked so pale, so thin, so different even to when they parted, that the warm heart of Emmeline could not be restrained, for she knew, however resignation might be, nay, was felt, it was a bitter pang to that gentle girl to leave her native land, and the friends she so much loved; but recalling her promise, with a strong effort she checked her own sorrow, and endeavoured with playful fondness to raise the spirits of her friend.
The day passed cheerfully, the young people took a drive for some few miles in the vicinity of Dover, while Mr.Hamilton, acting the part of a brother to the favourite _protegee_ of his much-loved mother, listened to her plans, counselled and improved them, and, indeed, on many points proved himself such a true friend, that when Mrs.Greville retired to rest that night, she felt more at ease in mind than for many months she had been.
The following day was employed in seeing the antiquities of Dover, its ancient castle among the first, and with Mr.Hamilton as a cicerone, it was a day of pleasure to all, though, perhaps, a degree of melancholy might have pervaded the party in the evening, for the recollection would come, that by noon on the morrow, Mrs.Greville and Mary would bid them farewell.

In vain during that day had Herbert sought for an opportunity to speak with Mary on the subject nearest his heart, though they had been so happy together; when for a few minutes they found themselves alone, he had fancied there was more than usual reserve in Mary's manner, which checked the words upon his lip.
