Not only had Darrell retained to himself the secret of the cavern, but he had also conceived the idea of hiding it from the observation of passing vessels by means of a canvas screen drawn over its entrance, and cleverly painted to resemble the adjacent cliffs.
Surrounded by these safeguards, and further protected by its locality in that desolate region, the unlawful business flourished amazingly. It not only yielded its chief promoter a sufficient income to support his family comfortably in their distant Eastern home and enable him to keep his mining-plant in good repair, but each year saw a very tidy surplus stored away for the future development of the Copper Princess.
Darrell had learned of his partner's death, and waited anxiously for years to hear from the Peveril heirs. As they remained silent, and made no claim against the property in which his own life was so completely bound up, he cherished the belief that they considered it too worthless even to investigate, and that he would be left in undisturbed possession to the end. He became so emboldened by this belief that, when the term of contract had so nearly expired that it had but a few months more to run, he even began in a small way to resume work in the mine. Thus he had it pumped out and partially retimbered. He also started work on a new level, and in every way possible, without attracting too much attention, got his property ready for the great scheme of development upon which he was determined the moment he should be freed from his contract.
In the meantime his wife had died, and his only child, who had been born since he entered upon this strange existence, had come to share his lonely home. As she was but twelve years old when this great change in her life took place, she of course knew nothing of business, and had never heard of such a thing as smuggled goods. In her eyes everything that her dear papa did was right, and she was too happy at being permitted to become in any degree his assistant to think of questioning his methods.
So the secret of the cavern and its underground connection was finally confided to her. She was also intrusted with the duty of watching for the little vessels that brought the goods in which her father dealt, and of hanging out the signal-lights by which their movements were guided. As these lights were always displayed from the stunted cedar at the mouth of the cavern, and as this place also served her for a post of observation, she passed much of her time within the limits of the great cave.
