later for dinner. That afternoon, after the conclusion of some odd hissing sounds which came from behind the locked portal, he did finally appear, wearing an extremely haggard aspect and forbidding anyone to enter the laboratory upon any pretext. This, indeed, proved the beginning of a new policy of secrecy; for never afterward was any other person permitted to visit either the mysterious garret workroom or the adjacent storeroom which he cleaned out, furnished roughly, and added to his inviolably private domain as a sleeping apartment. Here he lived, with books brought up from his library beneath, till the time he purchased the Pawtuxet bungalow and moved to it all his scientific effects.
In the evening Charles secured the paper before the rest of the family and damaged part of it through an apparent accident. Later on Dr. Willett, having fixed the date from statements by various members of the household, looked up an intact copy at the Journal office and found that in the destroyed section the following small item had occurred:
Nocturnal Diggers Surprised in North Burial Ground.
Robert Hart, night watchman at the North Burial Ground, this morning discovered a party of several men with a motor truck in the oldest part of the cemetery, but apparently frightened them off before they had accomplished whatever their object may have been.
The discovery took place at about four o'clock, when Hart's attention was attracted by the sound of a motor outside his shelter. Investigating, he saw a large truck on the main drive several rods away; but could not reach it before the sound of his feet on the gravel had revealed his approach. The men hastily placed a large box in the truck and drove away toward the street before they could be overtaken; and since no known grave was disturbed, Hart believes that this box was an object which they wished to bury.
The diggers must have been at work for a long while before detection, for Hart found an enormous hole dug at a considerable distance back from the roadway in the lot of Amosa Field, where most of the old stones have long ago disappeared. The hole, a place as large and deep as a grave, was empty; and did not coincide with any interment mentioned in the cemetery records.
