Presently Nenci, placing the bust upon the ground, boldly struck a match, and by its fickle light ascertained the depth of the hole. Malvano was still working away, fearful lest they should be discovered, the perspiration dropping from his brow in great beads.

“I think that’s deep enough,” he said after some minutes had elapsed. Then, striking another vesta, he glanced intently at his watch to ascertain the exact time. He handed the Doctor the matches, asking him to strike another, and by its aid held the bust upside down and moved the base very carefully round. When at last he had placed it at the exact point, he knelt and slowly lowered it into the hole which had been dug. Both men, working like moles in the dark, quickly replaced the earth, Nenci stamping it down with his feet. At risk of detection—for a lighted match can be seen a long way on a dark night—they struck two more vestas in order that they might the more completely hide the beautiful little work of art upon which Nenci had been engaged so many hours that day.

When it had been entirely covered, and the ploughed land rearranged, both men retreated rather hurriedly across a couple of fields, and at an old weather-worn stile stood and waited, peering back into the darkness.

The chimes of a distant church sounded over the hills; then the dead silence of the night fell again unbroken, save for the mournful sighing of the wind. For fully five minutes they waited, uttering no word.

“It’s failed,” Malvano at last exclaimed disappointedly, in an excited half-whisper.

“I tell you it can’t fail,” the other answered quickly. “I ought to know something of such contrivances.” Malvano muttered some words expressive of doubt, but scarce had they left his lips when all of a sudden there was a blood-red flash, a loud report, and tons of earth and stones shot skyward in the darkness, some falling unpleasantly close to them.

“Holy Virgin!” ejaculated the Doctor. “It’s terrible! By Heaven it is!”

“Nothing could withstand that,” Nenci observed enthusiastically, with an air of complete satisfaction. “I told you it was absolutely deadly.”

The report had caused the earth to tremble where they stood, and, borne upon the night wind, had no doubt been heard for miles around. Losing no time, they sped quickly forward towards the spot, and there in the gloom discerned that a great oak in the vicinity had been shattered, its branches hanging torn and broken, while at the spot where the little bust had been buried, was a wide, deep, funnel-shaped hole. Some great hazel bushes in the vicinity had been torn up by the roots and hurled aside, while on every hand was ample evidence of the terrific and irresistible force of the explosion.

“The strength of the compound is far greater than I ever imagined! It’s frightful?” exclaimed the Doctor, gazing around half fearfully. “But let’s get back, or some one, attracted by the report, may be astir. What will people think when it’s discovered in the morning?”
