As the lieutenant had intimated, the draught was uninviting to one not very thirsty. The rivulet issued from under the roots of a tree, where it was to be supposed it would be quite cool, but it was lukewarm and roiled, as the officer learned when he quenched his thirst during the afternoon, but the drink was none the less refreshing on that account.

“Freeman,” said the lieutenant, looking around them, as if suspecting the presence of an enemy in their vicinity, “suppose you wait here for a few minutes, while I go back to the old spot.”

“Why do you propose that?”

“I fancied just now I heard something suspicious. Maybe I was mistaken, but when you are in this confounded Apache country, the rule is to believe every man guilty until proved innocent.”

“And if you were not mistaken?”

“Well,” replied the young officer in his off-hand way, “it’s likely in that case that there will be music in the air.”

“I mean as to what I shall do. Am I to stand here and take no part in the business? Is that your idea of how one comrade should stand by another?”

The question may seem trifling, but it perplexed the lieutenant for the moment. The idea of comradeship with him, as it is with every true soldier, is that one shall stand by his friend to the death. The basest crime that a soldier can commit is to desert a comrade in extremity. Ordinarily, therefore, the answer of Decker would have been prompt, or rather there would have been no occasion for asking the question, but while Freeman was a brave man, his powers of keen, subtle reasoning, of cool-headedness and quick resources were affected by his mental distress over the peril and uncertainty about his little boy. It is the rule among physicians for no member of the profession to attend unaided his own family (unless the peril make it unavoidable), since affection must weaken the judgment. The situation of the father was somewhat analogous.

In other words the thought of the lieutenant was that it would be safer for them to be apart, if danger should come. The elder not only could not aid the younger, but would increase his own peril. He must, therefore, stay where he was.
