There is nothing that brings men so close to each other as a common grievance or a common danger. Men who find pleasure in the same game or the same pursuit are drawn together by a common taste; but in the indulgence of it there is sure to arise, sooner or later, a spirit of competition. Now, this spirit, which is in most human affairs, is a new bond of union when men are fighting side by side against a common foe.

During the three days that followed Durnovo's departure from Msala, Jack Meredith and Oscard learnt to know each other. These three days were as severe a test as could well be found; for courage, humanity, tenderness, loyalty, were by turns called forth by circumstance. Smallpox rages in Africa as it rages nowhere else in these days. The natives fight it or bow before it as before an ancient and deeply dreaded foe. It was nothing new to them, and it would have been easy enough for Jack and Oscard to prove to their own satisfaction that the presence of three white men at Msala was a danger to themselves and no advantage to the natives. It would have been very simple to abandon the river station, leaving there such men as were stricken down to care for each other. But such a thought never seemed to suggest itself.

The camp was moved across the river, where all who seemed strong and healthy were placed under canvas, awaiting further developments.

The infected were carried to a special camp set apart and guarded, and this work was executed almost entirely by the three Englishmen, aided by a few natives who had had the disease.

For three days these men went about with their lives literally in their hands, tending the sick, cheering the despondent, frightening the cowards into some semblance of self-respect and dignity. And during these three days, wherein they never took an organised meal or three consecutive hours of rest, Joseph, Meredith, and Oscard rose together to that height of manhood where master and servant, educated man and common soldier, stand equal before their Maker.

Owing to the promptness with which measures had been taken for isolating the affected, the terrible sickness did not spread. In all eleven men were stricken, and of these ten died within three days. The eleventh recovered, but eventually remained at Msala.

It was only on the evening of the third day that Jack and Guy found time to talk of the future. They had never left Durnovo's house, and on this third day they found time to dine together.

“Do you think,” Oscard asked bluntly, when they were left alone to smoke, “that Durnovo knew what was the matter?”

“I am afraid that I have not the slightest doubt of it,” replied Jack lightly.

“And bolted?” suggested Oscard.
