They don't often frequent jungles, but we're only about a day's march to more open terrain."

"Whatever that is. Talk English. Geeze! What was that?" A series of coughing grunts rose from somewhere in the solid black wall of jungle that surrounded the camp, to be followed by a thunderous roar that shook the earth.

"Simba!" cried one of the blacks, and immediately a half dozen men hastened to add fuel to the fires.

"Gunner" Patrick leaped to his feet and ran into the tent, emerging a moment later with a Thompson submachine gun. "T'ell with a rod," he said. "When I get that baby on the spot I want a typewriter."

"Are you going to take him for a ride?" inquired Lafayette Smith, whose education had progressed noticeably in the weeks he had spent in the society of Danny "Gunner" Patrick.

"No," admitted Danny, "unless he tries to muscle in on my racket."

Once again the rumbling roar of the lion shattered the quiet of the outer darkness. This time it sounded so close that both men started nervously.

"He appears to be harboring the thought," commented Smith.

"What thought?" demanded the "Gunner."

"About muscling in."

"The smokes got the same hunch," said Danny. "Look at 'em."

The porters were palpably terrified and were huddled close to the fires, the askaris fingering the triggers of their rifles. The "Gunner" walked over to where they stood straining their eyes out into the impenetrable darkness.

"Where is he?" he asked Ogonyo, the headman. "Have you seen him?"

"Over there," said Ogonyo. "It looks like something moving over there, bwana."

Danny peered into the darkness. He could see nothing, but now he thought he heard a rustling of foliage beyond the fires. He dropped to one knee and aimed the machine gun in the direction of the sound. There was a burst of flame and the sudden rat-a-tat-tat of the weapon as he squeezed the trigger. For a moment the ringing ears of the watchers heard nothing, and then, as their auditory nerves returned to normal, to the keenest ears among them came the sound of crashing among the bushes, diminishing in the distance.

"I guess I nicked him," said Danny to Smith, who had walked over and was standing behind him.

"You didn't kill him," said Smith. "You must have wounded him."

"Simba is not wounded, bwana," said Ogonyo.

"How do you know?" demanded Danny. "You can't see nothin' out there."

"If you had wounded him he would have charged," explained the headman. "He ran away. It was the noise that frightened him."

"Do you think he will come back?" asked Smith.

"I do not know, bwana," replied the negro. "No one knows what Simba will do."

"Of course he won't come back," said Danny. "The old typewriter scared him stiff. I'm goin' to turn in."

Numa, the lion, was old and hungry. He had been hunting in the open country; but his muscles, while still mighty, were not what they had been in his prime. When he reared to seize Pacco, the zebra, or Wappi, the antelope, he was always just a trifle slower than he had been in the past; and his prey eluded him. So Numa, the lion, had wandered into the jungle where the scent of man had attracted him to the camp. The beast fires of the blacks blinded him; but, beyond them, his still keen scent told him there was flesh and blood, and Numa, the lion, was ravenous.

Slowly his hunger was overcoming his inherent urge to avoid the man-things; little by little it drew him closer to the hated fires. Crouched almost upon his belly he moved forward a few inches at a time. In another moment he would charge--and then came the sudden burst of flame, the shattering crash of the machine gun, the shriek of bullets above his head.

The startling suddenness with which this unexpected tumult broke the fear laden silence of the camp and the jungle snapped the taut nerves of the great cat, and his reaction was quite as natural as it was involuntary. Wheeling in his tracks, he bounded away into the forest.

The ears of Numa, the lion, were not the only jungle ears upon which the discord of "Gunner" Patrick's typewriter impinged, for that seeming solitude of impenetrable darkness harbored a myriad life. For an instant it was motionless, startled into immobility; and then it moved on again upon the multitudinous concerns of its varied existence. Some, concerned by the strangeness of the noise, moved farther from the vicinity of the camp of the man-things; but there was at least one that curiosity attracted to closer investigation.

Gradually the camp was settling down for the night.
