The sister he had known for some years, but had never been particularly interested in her until within a few months.

Distancing his observation, her mind had matured; and the graces of art, education and accomplishment, had thrown their winning attractions around her.

First, almost as a brother, he began to feel proud of her beauty and intelligence; admiration followed, and, before he was aware of the tendency of his feelings, they had taken on a warmer than fraternal glow.
All things tended to encourage this incipient regard; and, as Miss Arden herself favored it, and ever turned towards Hendrickson the sunniest side of her character, he found himself drawn onwards almost imperceptibly; and had even begun to think seriously of her as his wife, when the meeting with Mrs.Dexter revealed the existence of sentiments on both sides that gave the whole subject a new aspect.
A very difficult problem now presented itself to the mind of Mr.
Hendrickson, involving questions of duty, questions of honor, and questions of feeling.

It is not surprising that Miss Arden found a change in her travelling companion, nor that her visit to Niagara proved altogether unsatisfactory.

No one could have been kindlier, more attentive, or more studious to make her visit attractive.
