"Oh, you can ride very well," she laughed, "but—"

She did not finish the remark, and the secretary, after a painful scrutiny of the silent banjo in her lap, went away to the stables and ordered his horse. But a man is a fool to ride hard along the bank of a Brazilian river in the heat of the afternoon.

From one of the windows of his cool room, Hemming watched the departure of the President's private secretary. He remembered what Tetson had said of the boy,—"too young to associate with men."

But youth is a thing easily mended, thought Hemming. Somehow—perhaps only in size—Hicks recalled O'Rourke to his mind; and back to him came the days of their good-comradeship. He wondered where O'Rourke was now, and what he was busy about. He had seen him last in Labrador, where they had spent a month together, salmon fishing, and up to that time O'Rourke had found no trace of Miss Hudson. Ellis's information had proved useless. Disgusted at the deception practised upon him, the poor fellow had ceased to speak of the matter, even with his dearest friend during night-watches by the camp-fire.

CHAPTER IV.
THE THING THAT HAPPENED

Hicks came along the homeward road at dusk. Lights were glowing above the strong walls and behind the straight trunks of the palms. A mist that one might smell lay along the course of the river. Hicks rode heavily and with the air of one utterly oblivious to his surroundings. But at the gateway of the officers' mess he looked up. Captain Santosa was in the garden, a vision of white and gold and dazzling smile. He hurried to the gate.

"Ah, my dear Hicks, you are in time for our small cocktails, and then dinner. But for this riding so hard, I can call you nothing but a fool."

"Thanks very much," replied the American, dismounting slowly, "and as to what you call me, old man, I'm not at all particular." The woebegone expression of his plump face was almost ludicrous.

Santosa whistled, and presently an orderly came and took Valentine's horse. The two entered the building arm in arm, and the secretary swayed as he walked.
