A moment later he took the small white hand that was held out to him.

"Mr. Mallory," said the girl, gazing at him earnestly, "I shall not wait for any one to introduce you to me. I must tell you that I appreciate your bravery."

Mark bowed and thanked her; he could think of nothing more to say.

"They just let me out of the hospital to-day," she continued, "and I made up my mind that the very first thing I was going to do was to tell you what I thought of your courageous action on my behalf. I want to know you better, Mr. Mallory."

She said it in a plain and simple way that Mark liked, and he told her that nothing would please him more.

"I would ask you to take a walk with me now," said Grace, "but for all those cadets who are with me. I don't think they'd relish that, you being a fourth class man."

"I don't think they would," responded Mark, with a queer smile which the girl did not fail to notice.

"I don't care!" she exclaimed, suddenly. "They can get mad if they want to. I think a great deal more of some plebes than I do of yearlings. Excuse me just a moment."

And then, to Mark's infinite glee, this beautiful creature hurried over and said something to the group of cadets, at which they all bowed and walked off rather stiffly, sheepishly, Mark thought. The girl rejoined him, with a smile.

"I told them they'd have to excuse me," she said, as she took Mark's arm. "I told them I owed you a debt of gratitude, and I hoped they wouldn't mind."
