"Powerful," Van commented, his nerves tightening as the impact of that information struck him. "A few grains, you say? No more?"
"A very few grains, Professor Bendix. And—" Junes smacked his palms together sharply—"it happened! My assistants do not agree with me in my refusal to continue. But consider—what would happen to humanity if the explosive power of the formula I nearly discovered became a reality! The whole world would be at the mercy of whoever could control that metallurgical combination. It is too dangerous, too terrible to contemplate. So I have refused to go on!"
"It's an endothermic compound, I presume," Professor Bendix suggested, and when Junes nodded agreement, "At what temperature did you expect to make the aluminum-calbite fusion?"
"Impossible to say," Junes declared warmly. "These furnaces produce the greatest heat of any man-made generators yet devised. And they fall considerably short of a real fusion. I've added ammonium nitrate—" He paused, frowned. "But enough. I am done. I will not jeopardize humanity."
The man at the rheostat said sullenly, "Dr. Junes is very stubborn, Professor Bendix. The explosion this afternoon has him imagining too many things a scientist should never consider."
"Bah!" Junes exploded. "You—all of you! I will not be driven, nor forced! Nor bribed. Nor threatened!" His voice rose to a suddenly terrified screech, a pitch that seemed without reason.
Two of the assistants grabbed and held him. The rheostat man nodded curtly, asked Bendix:
"Could you, Professor, finish the doctor's experiment—if you were without his hysterical prejudices?"
"Perhaps," Van answered evenly. "Given time."
Dr. Junes' tall figure jerked violently, shuddered, and suddenly collapsed as the two men let him loose. He staggered, stepped backward, his eyes wide with quick terror, staring at the opening behind Van where the steel ladder led up to the sub-cellar corridor above.
The Phantom whirled, knocking against Lannigan's big hand that almost automatically was reaching for a hidden revolver. Van gave Jerry a warning signal to wait. Then Professor Paul Bendix settled his gaze on that exit.
Standing in the well-like opening was a tall, powerfully built figure dressed in a caped black robe with a black hood over a head whose face was masked in white. The next moment the terrifying figure moved into the room.
A frightful scream of agony slashed the silence, shot a blood-chilling shock through Van as he spun back, stared with momentarily paralyzed muscles at the gaunt, writhing form of Junes.
The scientist was sprawled backward halfway across the top of the white-hot furnace plates, his body held there by the adhesive, scorching flesh that stuck to the plates and was filling the room with a nauseating stench. A final shriek died on the doctor's lips. The whole upper half of his body shriveled; the arms alone waving spasmodically in unconscious, dying reflexes.
The Phantom sprang for the rheostat, knocked aside the third masked man standing near it. He spun off the electric dial control, turned to watch the scientist's limp body slide down off the furnace.
For a fleeting second, as one of the men wearing the welding mask bent over Junes' dead body, Van caught a glimpse of the handle of a hypodermic syringe in the fellow's coat pocket. The next moment the handle had slipped down out of sight.
"A regrettable accident," the hooded figure stated sullenly, and glanced at Professor Paul Bendix with icy determination. "Did I hear you say you could carry on the unfortunate scientist's work?"
"This furnace wasn't hot enough for the experiment, anyhow," the masked man who had been at the rheostat declared. "We've been watching this stove seven hours, and the metals won't fuse."
The Phantom's seething mind clicked to a grim conclusion. He was being asked to take the place of the dead scientist. Junes had refused to aid these men in what ever plan they had proposed. Van had not positive proof, but already suspected that the doctor had been shoved onto that furnace and murdered. He decided to join them, let them force him into their scheme.
He nodded, inclined his head gravely, saw even then out of the corner of his eye what was going to happen, as he indicated Lannigan.
"Yes, it is entirely possible that I could conduct the unfortunate doctor's experiment," he said. "If I have my assistant."
At a nod from the hooded figure, one of the men had stepped close to Jerry Lannigan. A faintly blue vapor curled up swiftly from a pencil in the man's hand, and Jerry dropped unconscious to the floor.
"You shall have your assistant," the icy voice promised with a note of satanic humor. He pocketed the small chip of silver-colored ore on the stone bench, and advanced on Van.
The next instant a second pencil ejected a shot of that bluish brain-fogging gas straight into the Phantom's bearded face. The room whirled dizzily for a second that seemed endless, while the hooded face leered. Then oblivion blotted out the room.
Chapter Seven.
Destination Darkness
Jolting movement and the sound of rushing wind and an automobile motor's powerful throbbing rhythm beat into the Phantom's drugged brain.
He tried to open his eyes, but the tight pressure of tape on them kept the lids shut. His hands were fastened behind his back with tape. He lurched helplessly with each swerving plunge of the car, his body held upright between two men in the seat beside him.
His parched lips were taped shut, and hunger gnawed at his stomach, giving him the only measure of the passage of time. Eight hours or longer, he judged, since he had been knocked out with those bluish odorless fumes.
The last physical sensations he remembered were the smell of fulmigated sulphur and the heat in that sub-cellar of the General Electric metallurgical laboratory. But now the fresh odor of pines, an occasional lingering whiff of burning coal, and the rush of cool air assailed his senses.
He listened keenly, trying to pick up the rumbling roar of Niagara Falls, but could hear only the hum of the motor and the swish of the wind. The totality of his blind impressions was of steep long climbs, quick descents and open spaces.
The two men sitting beside him began to stir restlessly. A match scraped, followed by the pungent odor of cigarette smoke.
"Making good time for a long ride," one of the men said in a tired voice. "Almost there now. The other car'll be there already."
"Yeah," the other rider agreed. "Not a hitch on this trip. That's what organization does. You going to try for a sergeant's circles?"
"I ain't killed nobody yet," the other grumbled. "Anyhow, not officially. Soon's I do, though, I'll sure apply for the next rating. Sergeant's get plenty of authority."
"You won't have to wait long for a chance to get a killing credit," the second man prophesied knowingly. "I heard, from one of the district majors, that th' State Militia is commin' after us."
"Better not talk too much," the man on Van's right warned. "I heard somethin' about that, too, but you know what the penalty is for not keepin' your mouth shut!"
Van could tell by the movement of the man's body that the guard had gestured significantly at him.
In the prolonged, moody silence that followed, the Phantom tried to fathom the motives and extent of the mysterious organization that three times now had reared its ugly, poisonous head, There was but the one conclusion—some secret society was plotting to overthrow the government of the United States, and was relying upon some new unannounced discovery of modern science to effect their treacherous ends.
And that the dead Dr. Hugo Junes' metallurgical experiments with aluminum and calbite had something to do with those murderous plans appeared obvious. The Phantom was convinced that Dr.
