But the momentary astonishment and embarrassment were his alone.
He scarcely recognized her.

She was wearing the garments he had brought her the day before--a certain discarded gown of Miss Nellie Wynn, which he had hurriedly begged from her under the pretext of clothing the wife of a distressed overland emigrant then on the way to the mines.

Although he had satisfied his conscience with the intention of confessing the pious fraud to her when Teresa was gone and safe from pursuit, it was not without a sense of remorse that he witnessed the sacrilegious transformation.

The two women were nearly the same height and size; and although Teresa's maturer figure accented the outlines more strongly, it was still becoming enough to increase his irritation.
Of this becomingness she was doubtless unaware at the moment that he surprised her.

She was conscious of having "a change," and this had emboldened her to "do her hair" and otherwise compose herself.
