Here Mrs Stacer, good woman that she was, volunteered to put matters straight, for the night at all events. She at once saw Mr Gunton, and explained the impasse to him; and Horace was comfortably installed, away from the Professor’s room, in the farmer’s own quarters.

“Leave my brother to me,” said Mrs Stacer, as she left Horace. “I daresay matters will come right.”

At ten o’clock Mrs Stacer came to the door. Mr Gunton rose and went out as she entered. “H’sh!” she said with mock-mystery as she addressed Horace. “I think,” she went on, with a comical little smile, “the Professor begins to think he has done you an injustice. He is amazed at our knowing you, and we have attacked him all the evening, and he is visibly relenting.”

“Mrs Stacer,” said Horace warmly, “I can’t thank you sufficiently. I’ve had an inspiration since I saw you. I, too, have discovered, not far from here, a rather good new butterfly—a species hitherto unknown. Can’t I make amends, by sharing my discovery with the Professor? I’ve got specimens here in my box, and there are plenty in a kloof fifteen miles away.”

“Why, of course,” answered Mrs Stacer. “It’s the very thing. Your new butterfly will turn the scale I’ll go and tell my brother you have a matter of importance to communicate, and wish to make further explanations. Wait a moment.”

In three minutes she returned. “I think it will be all right,” she whispered. “Go and see him. Straight through the passage you will find a door open, on the right. I’ll wait here.”

Horace went forward and came to the half-open door. The Professor, who had changed his loose, yellow, alpaca coat for a black one of the same material, sat by a reading-lamp. He wore now his gold-rimmed spectacles, in lieu of the blue “goggles.” He looked clean, and pink, and comfortable, though a trifle severe—the passion of the afternoon had vanished from his face. Horace spoke the first word. “I have again to reiterate Professor, how vexed I am to have disturbed your collecting-ground. I had not the smallest intention of doing it. Indeed, my plans lay farther north. It was the pure accident of meeting my old school-friend, Marley, that led me here. In order to convince you of my sincere regret, I have here a new butterfly—evidently a scarce and unknown Eurema—which I discovered a few days since, near here. My discovery is at your service. Here is the butterfly. I trust you will consider it some slight set-off for the vexation I have unwittingly given you.”

At sight of the butterfly, which Horace took from his box, the Professor’s eyes gleamed with interest. He took the insect, looked at it very carefully, then returned it.

“Mr Maybold,” he said, rising and holding out his hand, “I believe I did you an injustice this afternoon. I lost my temper, and I regret it. I understand from my sister and daughter that they are acquainted with you, and that they were fully aware of your original intention to travel to the Orange River. Your offer of the new butterfly, which is, as you observe, a new and rare species, is very handsome, and I cry quits. I trust I may have the pleasure of seeing you to-morrow at breakfast, and accompanying you to the habitat of your very interesting and remarkable discovery.”

Before breakfast next morning there was a very pleasant and even tender meeting between Horace Maybold and Rose Vanning; and, when Mrs Stacer joined them, there was a merry laugh over the adventures of yesterday.
