"Bring the mattock," said the Doctor, cautiously uncovering the light. But though Bartholomew tugged with great energy, the Doctor helping, it was to little purpose, for the stump was immovable.

"We had best try the probe." Saying this, the warder drew

forth an instrument in shape something like unto a large auger. He could by this means easily ascertain if anything hard were below, or any symptons of concealed treasure. As they were thus engaged a hollow voice, to their terrified apprehensions issuing from the ground, cried out—

"Hold!"

The treasure-hunters came to a full pause. The wind and rain at the same time beat so heavily they could not ascertain the sequel to this injunction.

"'Tis Nargal, the spirit who guards hidden treasures," said Dee: "we can approach him only by prayers and fumigations."

"Then must we return?" said Bartholomew, apparently unwilling to desist.

"Hark!" said the Doctor, listening.

They heard a moan, as that of some one in great pain. Presently a faint shriek stole through a pause in the blast.

"'Tis like the groan of a mandrake," he continued: "they do ever lament and bewail thus when gathered. I doubt not but this tree is of that accursed nature."
