Uniformly correct and courteous of manner, she rarely spoke, save when necessary. It was as if she had declared, “I will not talk. If this be mystery, make the most of it.”

Old Salt, apparently, backed her up in this determination, and allowed her to sit next him at table, without addressing her at all.

More, he often took it upon himself to answer a remark or question meant for her and for this he sometimes received a fleeting glance, or a ghost of a smile of approval and appreciation.

But all this was superficial. The Adamses, between themselves, decided that Miss Austin was more deeply mysterious than was shown by her disinclination to make friends. They concluded she was transacting important business of some sort, and that her sketching of the winter scenery, which she did every clear day, was merely a blind.

Though Mrs. Adams resented this, and urged her husband to send the girl packing, Old Salt demurred.

“She’s done no harm as yet,” he said. “She’s a mystery, but not a wrong one, ’s far’s I can make out. Let her alone, mother. I’ve got my eye on her.”

“I’ve got my two eyes on her, and I can see more’n you can. Why, Salt, that girl don’t hardly sleep at all. Night after night, she sits up looking out of the window, over toward the college buildings—”

“How do you know?”

“I go and listen at her door,” Mrs. Adams admitted, without embarrassment. “I want to know what she’s up to.”

“You can’t see her.”
