Just what did it make Katie think of?
He enumerated various things it made him think of, only to express his dissatisfaction with them all as inadequate.

Had Katie ever seen any one so beautiful?
And with such an adorable shy little way?
Had Katie ever heard her say anything about him?
Did she think he had any chance?
Was there any other fellow?
Of course there must have been lots of other fellows in love with her--a girl like that--but had she cared for any of them?
Would Katie tell him something about her?
She had been reserved about herself--the kind of reserve a fellow wouldn't try to break through.

Would Katie tell him of her life and her people?
Not that it made any difference with him--oh, he wanted just her.

But his mother would want to know--Katie knew how mothers were about things like that.

And he did want his mother to like her.
