“Of my weakness, yes,” said Markham, with a little laugh. “It was wretchedly weak to allow myself to be affected by the change from the open air to that room, but it felt stifling to me.”

“I didn't feel the difference to be anything considerable,” said Harwood; “so the fact of your being overcome by it proves that you are not in a fit state to be playing with your constitution. Where did you ride to-day?”

“Where? Upon my word I have not the remotest idea,” said Markham. “I took the road out to Simon's Bay, but I pulled up at a beach on the nearer side of it, and remained there for a good while.”

“Nothing could be worse than riding about in this aimless sort of way. Here you are completely knocked up now, as you have been for the past three evenings. Upon my word, you seem indifferent as to whether or not you ever leave the colony alive. You are simply trifling with yourself.”

“You are right, I suppose,” said Markham wearily. “But what is a fellow to do in Cape Town? One can't remain inactive beyond a certain time.”

“It is only within the past three days you have taken up this roving notion,” said Harwood. “It is in fact only since that Government House affair.” Markham turned and looked at him eagerly for a moment. “Yes, since your weakness became apparent to yourself, you have seemed bound to prove your strength to the furthest. But you are pushing it too far, my boy. You'll find out your mistake.”

“Perhaps so,” laughed the other. “Perhaps so. By the way, is it true that you are going up country, Harwood?”

“Quite true. The fact is that affairs are becoming critical with regard to our relations with the Zulus, and unless I am greatly mistaken, this colony will be the centre of interest before many months have passed.”

“There is nothing I should like better than to go up with you, Harwood.”

Harwood shook his head. “You are not strong enough, my boy,” he said.
