"I'm afraid it will be one of those mysteries which will never be explained," mused the youngest Rover boy, as he jumped into the cutter which he was using and drove away from Ashton. "It's too bad! Oh! how I'd like to get my hands on that rascal, whoever he may be!"
It was not until two days later, when Songbird was once more able to be about and had insisted on being driven over to the Sanderson place, that Sam had a chance to go on the sleighride with Grace Laning. He drove over to Hope Seminary about four o'clock in the afternoon, having sent word ahead that he was coming. Grace was waiting for him, and the pair speedily drove away, wistfully watched by a number of the girl students.
"It's so nice of you to think of me, Sam, when you've got so much to think about on poor Songbird's account," said Grace, as they were speeding out of the seminary grounds. "How is he?"
"Oh, he's doing better than we expected, Grace. He insisted on being driven over to the Sandersons this afternoon. Stanley took him over, because none of us thought Songbird was strong enough to drive himself."
"I want you to give me all the particulars of the attack," said the girl, and this the youth did readily.
"It must have been the man who stuttered and whistled—the fellow Songbird saw at the Knoxbury bank," declared the girl, positively. "Wouldn't it pay to get a detective on his track?"
"Perhaps so, Grace. I think Songbird is going to mention that to Mr. Sanderson."
Sam did not want the girl to worry too much over what had occurred and so soon changed the subject. They talked about college and seminary matters, and then about affairs at home, and about matters in New York City.
"I just got another letter from Nellie to-day," said Grace. "She says that the apartment she and Tom have rented is perfectly lovely—every bit as nice as the one occupied by Dick and Dora."
"I'm glad they like it, Grace. But, believe me, it will be some job for Tom to settle down and be a staid married man! He was always so full of fun."
