Before the young officer could reply, they heard some one approaching and glancing up Bettina discovered Billy Webster.
The next moment, without awaiting their invitation, Billy took a seat on the sands beside them.
Bettina was not surprised, for few persons who knew Billy intimately continued to be surprised by his unexpected actions. Indeed, they would have been surprised had he behaved otherwise. Now, although Bettina was a little annoyed at having her conversation interrupted, she made no effort to interfere with his intention.
The turning of Billy Webster from the accomplishment of his desire required a tremendous amount of energy which the result scarcely ever justified.
So far as Lieutenant Carson was concerned, because Billy looked so much younger than he actually was, he regarded him merely as a presuming small boy.
Moreover, at the beginning of their talk, certainly Billy behaved like one. First he stared at Lieutenant Carson's dress uniform, with the single bar on his collar and sleeve and then up into the officer's firm, smooth-shaven face. Finally, leaning over close to his companion, he fastened his large visionary blue eyes upon the officer's steadfast brown ones.
"Why did you do it?" Billy inquired. Then, because he was accustomed to being compelled to explain himself, he continued: "I mean why did you volunteer, why go through all the hard work and rigmarole to be appointed an officer in the army? You look as if you had an unusual lot of sense, so I cannot imagine that you do not understand there are finer things to do with one's life than killing people. I should think you could see how much more men are called upon to conquer poverty and injustice and the crime that comes of it, than they are called upon to conquer one another. Of course if you had been drafted that would have been a different matter. Most people do what other people tell them to do. That is why I believe if all the leaders of the world would preach peace, all war would end."
Instead of appearing to take the youthful pacifist seriously, Lieutenant Carson smiled. Billy was a little offensive and misguided, nevertheless there was something interesting about the boy; he had such an intense manner, such an appearance of being convinced of his own point of view. And Billy's personality suggested the thinker, not the man of action.
"Then you are under the impression we are over there in our encampment for the fun of it and in order to kill time which we might be spending in better ways?" he inquired, thinking that perhaps he might answer Bettina's anxious questionings and Billy's impertinence at the same time. "Well, as a matter of fact, our encampment is not a very attractive place up to the present. Did you think so when you made us the visit? One job we have been tackling recently is to clear away the underbrush from a good many thousands of acres of desert which have remained undisturbed from the year one until now. We killed ninety rattlesnakes as a part of the first day's work. Later on we are going to drive artillery across those wastes of sand. Does not sound like play, does it?"
"No," Billy returned patiently, wondering why people would not sometimes answer his questions directly, without first preaching long sermons which seemed to have but little bearing upon them.
