She smiled assent, but Mars hung back. He knew well that I was once again coming forward with some intervention, and his blood was up, his anger still aglow; but I was not to be denied. He seized his forage-cap and stepped out with me into the starlit night.

"There is no time for apologies from an old fellow like me, Amory," said I, placing a hand involuntarily on his shoulder. "Forgive me if I pain you, or am too intrusive. I heard what happened at the opera to-night. Would you be willing to tell me how she came to know anything about Bella Grayson?"

"I told Miss Carrington myself," said Mars, rather shortly; and his hands went down in his pockets, and a very set look came into his face as he kicked at a projecting ledge in the uneven pavement.

"You know how I've grown to like you, youngster, and must know that I can have no other impulse or excuse in thus meddling with your affairs. I'm fond of her too, Frank, and have seen enough to-night—and before—to convince me that she would give a vast deal to unsay those thoughtless words. I do not excuse her conduct; but she never for an instant could have dreamed of its effect, and it did not take the news of your order to make her repent it bitterly. I could see that plainly. Amory, don't go without seeing her."

Mars made no reply whatever.

"Have you told your mother of this misunderstanding?" I asked.

"Not exactly. I have told her—she saw I was cut up about something and asked—that something had been said that was very hard to bear, but that I had rather not talk of it now. I was too much hurt."

"Well. Then I must say nothing further, my boy; but if I may ask anything for the sake of the friendship I feel for you and for them, tell your mother the whole affair, and let her guide your action. Now, forgive me, and good-night. We will meet in the morning."

He pressed my hand cordially enough, but still made no reply to my request. "Thank you, Mr. Brandon; good-night," was all he said, and Mr. Brandon walked gloomily homeward. Amantium iræ might be easy things to settle if left to the participants, but were vastly easier to stumble into.

Clear, cloudless, lovely dawned the morrow, and long before office hours I had breakfasted and betaken myself to headquarters. Mr. Parker was there, and Amory had been at the office, but Vinton had as yet put in no appearance. My first question was as to the probable time of departure of the troop, and Parker's tidings filled me with hope. The quartermaster had been unable to secure transportation for the horses in the "Howard." The troops could not sail before the following day. Meantime, he said, there was to be a review of the small force in the city that very afternoon, and the general had expressed a desire to have a look at the cavalry once more before they started for their new and distant sphere of duty. It was his favorite arm of the service, and he hated to part with them.
