'I tell you,' he declared forensically, lifting his hand for a gesture, 'I know! Haven't I demonstrated the infallibility of my line of action? If a man wants to--to gather cherries, let him go to a cherry tree; if he seeks pearls, let him find out the favourite habitat of the pearl oyster; if he desires a--a hat, let him go to the hatter's. It is the simplest thing in the world, though fools have woven mystery and difficulty about it. Now----' 'Yes, pops.' Helen sighed again and saw wisdom in rising to her feet. 'If you will begin unpacking I'll make our beds. And I'll get the fire started.' 'We can dispense with the fire,' he told her, setting to work with the first knot to come under his fingers. 'There is coffee in the thermos bottle and we can open a tin of potted chicken.' 'The fire makes it cosier,' Helen said, beginning to gather twigs. Last night coyotes had howled fearsomely, and even dwellers of the cities know that the surest safeguard against a ravening beast is a camp-fire. For a little while the man strove with his tangled rope; she was lost to him through the mesquite. Suddenly she came running back. 'Papa,' she whispered excitedly. 'There's some one already here.' She led him a few paces and pointed, making him stoop to see. Under the tangle of a thin brush patch he made out what she had seen. But a short distance from the spot they had elected for their camp site was a tiny fire blazing merrily. 'Ahem,' said Helen's father, shifting nervously and looking at his daughter as though for an explanation of this oddity. 'This is peculiar. It has an air of--of----' 'Why, it is the most natural thing in the world,' she said swiftly. 'Where would you expect to find a camp-fire if not near a spring?' 'Yes, yes, that part of it is all right,' he admitted grudgingly. 'But why does he hold back and thereby give one an impression of a desire on his part for secrecy? Why does he not come forward and make himself known? I do not mean to alarm you, my dear, but this is not the way an honest fellow-wayfarer should behave. Wait here for me; I shall investigate.' Intrepidly he walked toward the fire. Helen kept close to his side. 'Hello!' he called, when they had taken a dozen steps. They paused and listened. There was no reply, and Helen's fingers tightened on his arm. Again he looked to her as though once more he asked the explanation of her; the look hinted that upon occasion the father leaned on the daughter more than she on him. He called again. His voice died away echoless, the silence seeming heavier than before. When one of the horses behind them, turning from the water, trod upon a dry twig, both man and girl started. Then Helen laughed and went forward again.
