Mr. Hardy chatted apart for some time with the Guachos, anxious to know as much as possible of the country into which he was entering. The others chatted and told stories. Presently Mr. Hardy joined again in the general conversation, and then, during a pause, said, 'Although, my friends, I consider it most improbable that any Indians are in the neighbourhood, still it is just possible that they may have remained, on purpose to fall at night upon any party who might venture to pursue. At any rate, it is right to begin our work in a business-like way. I therefore propose that we keep watches regularly. It is now nine o'clock. We shall be moving by five: that will make four watches of two hours each. I should say that three men in a watch, stationed at fifty yards from the camp upon different sides, would suffice.' There was a general assent to the proposal. 'To save trouble,' Mr. Hardy went on, 'I suggest that we keep watch in the alphabetical order of our names. Twelve of us will be on to-night, and the next twelve to-morrow night.' The proposal was at once agreed to; and the three who were first on duty at once rose, and, taking their rifles, went off in various directions, first agreeing that one of them should give a single whistle as a signal that the watch was up, and that two whistles close together would be a warning to retreat at once towards the centre. The watch also ascertained which were the next three men to be roused, and these and the succeeding watches agreed to lie next to each other, in order that they might be roused without awakening their companions. In a few minutes there was a general unrolling of ponchos, and soon afterwards only sleeping figures could be seen by the dim light of the smouldering fire. Mr. Hardy, indeed, was the only one of the party who did not fall to sleep. Thoughts of the events of the last twenty-four hours, of the best course to be adopted, and of the heavy responsibility upon himself as leader of this perilous expedition, prevented him from sleeping. He heard the watch return, rouse the relief, and lay down in their places. In another half hour he himself rose, and walked out towards the sentry. It was a young man named Cook, one of the new settlers to the east of Mount Pleasant. 'Is that you, Mr. Hardy?' he asked, as he approached. 'I was just coming in to wake you.' 'What is it, Mr. Cook?' 'It strikes me, sir, that there is a strange light away to the south-west. I have only noticed it the last few minutes, and thought it was fancy, but it gets more distinct every minute.' Mr. Hardy looked out anxiously into the gloom, and quickly perceived the appearance that his friend alluded to. For a minute or two he did not speak, and then, as the light evidently increased, he said almost with a groan, 'It is what I feared they would do: they have set the prairie on fire. You need not keep watch any longer. We are as much separated from the Indians as if the ocean divided us.'
