After listening a few minutes, he decided to investigate for himself. This he did, not by proceeding in a direct line, as he could have done, but by making a circle which took him beyond the light of the fire until nigh enough to observe the animals.
They were on the ground, as though they had cropped their fill, and now enjoyed rest more than food. They appeared to be reposing quietly, and he concluded that the slight noise which he had noticed signified nothing. Horses and other domestic animals often start in their sleep, as though disturbed by dreams, the same as do we, and that which Nick heard may have been evidence of the fact.
Still, it is also a truth that men, when in situations of peril, frequently find it safer to rely more on the acuteness of their horse than upon their own vigilance. The animal seems to have his senses sharpened to the finest point, for his master’s good.
“I guess there’s nothing wrong,” said Nick to himself, after inspecting the ponies; “but it is best to act as though danger always threatens. That’s what Strubell and Lattin say, and everyone must see its logic.”
The fire was now burning so low that he gathered up a lot of wood and threw it on the flames. While thus employed, his gun lay on the ground near the feet of Herbert. The thought that, if any hostile prowler was near, it was the easiest thing in the world to pick him off, caused a strange feeling to come over the youthful sentinel, and his relief was great when able to catch up his gun and slip back in the protecting gloom of the night.
He had taken occasion, while near the fire, to glance at his watch, and, like his companion, was astonished to learn how brief the time was that he had been on duty. It was less than half an hour.
About the same period passed without the most trifling alarm. Nick studiously held himself in the background, where he moved slowly about, dreading to sit down, though often tempted to do so. He knew that so long as he kept the erect posture his senses would be at command, and it was far easier to do this by motion, no matter how slight, than by standing still.
He had reached the conclusion that the night was to be as uneventful as those that had preceded it, when once more one of the ponies uttered the same sound that had disturbed him before. Nick was startled, for the belief flashed upon him that this signified something. There must be some cause for the alarm of the animals, outside of themselves.
He reflected for a minute upon the most prudent thing to do. He dismissed the thought of awaking the Texans, for, like Herbert, he shrank from asking their help until certain it was needed, for, by so doing, he confessed his own inability to meet the danger, whatever it might be.
He now determined to make a much larger circuit than before, his object being to bring the horses between him and the fire. This would not only show the animals, but was likely to reveal the disturbing cause. At the same time, Nick himself could remain in the gloom, where it was hardly possible to be seen. The moon, which might have interfered with the success of this plan, would not be above the horizon for several hours to come.
