"I'll ask Gran'pa Jim."
Colonel Hathaway was rather amused at the efforts of the two girls to fathom the mystery of Old Swallowtail, but he was willing to assist in any practical way. So Uncle Eben drove them to the county seat next day and Josie spent several hours in the county clerk's office and paid a visit to the chief of police, who knew her father, John O'Gorman, by reputation. Mary Louise shopped leisurely while her friend was busy with her investigations and at last they started for home, where they arrived in time for dinner. On the way, Mary Louise inquired if Josie had secured any information of importance.
"A little," said the girl detective. "For one thing, old Hezekiah Cragg pays taxes on just one bit of land besides that little homestead of his. It is a five-acre tract, but the assessment puts it at an astonishingly low valuation—scarcely ten per cent of the value of all surrounding property. That strikes me as queer. I've got the plat of it and to-morrow we will look it up."
They found it was not easy to locate that five acres, even with a map, when the two girls made the attempt the next forenoon. But finally, at the end of a lonely lane about a mile and a half from the village, they came upon a stony tract hemmed in by low hills, which seemed to fit the location described. The place was one mass of tumbled rocks. Little herbiage of any sort grew there and its low assessment value was easily explained. The surrounding farms, all highly cultivated, backed up to the little waste valley, which was fenced out—or rather in—by the owners of the fertile lands. One faintly trodden path led from the bars of the lane the girls were in toward Mr. Cragg's five acres of stones, but amid the jumble of rocks it would be difficult to walk at all.
"This is an odd freak of nature," remarked Josie, gazing at the waste with a puzzled expression. "It is easy to understand why Mr. Cragg hasn't sold this lot, as he did all his other land. No one would buy it."
"Haven't the stones a value, for building or something?" asked Mary Louise.
"Not in this location, so far from a railway. In my judgment the tract is absolutely worthless. I wonder that so economical a man as Mr. Cragg pays taxes on it."
They went no farther than the edge of the rock-strewn field, for there was nothing more to see. Up the slope of the hill, on the far side from where they stood, were jumbled masses of huge slabs and boulders that might be picturesque but were not especially interesting. The girls turned and retraced their steps to the neglected lane and from thence reached the main road again.
"I have now satisfied myself on two counts," was Josie's comment. "First, that Mr. Cragg owns no property but this stone-yard and his little home, and second, that within the last forty years he has at different times disposed of seventy thousand dollars worth of land left him by his father. The county records prove that. The last sale was made about four years ago, so he has consistently turned all his real estate into ready money."
"What can he have done with so much money?" exclaimed Mary Louise.
