She turned her frightened eyes up to him. "Did some of the blacks really run away last night?" she asked.

"For Pete's sake, don't you start in too!" he exclaimed; then he got up and stamped away from the table.

At the foot of the table some one muttered something that sounded like that epithet which should always be accompanied with a smile; but it was not.

By ones and twos they finished their breakfasts and went about their duties. They went in silence without the customary joking that had marked the earlier days of the expedition.

Rhonda and Naomi gathered up the hand baggage that they always took in the car with them and walked over to the machine. Baine was at the wheel warming up the motor. Gordon Z. Marcus was stowing a make-up case in the front of the car.

"Where's Bill?" asked Rhonda.

"He's going with the camera truck today," explained Baine.

"That's funny," commented Rhonda. It suddenly occurred to her that he was avoiding her, and she wondered why. She tried to recall anything that she had said or done that might have offended him, but she could not. She felt strangely sad.

Some of the trucks had commenced to move toward the river. The Arabs and a detachment of askaris had already crossed to guard the passage of the trucks.

"They're going to send the generator truck across first," explained Baine. "If they get her across, the rest will be easy. If they don't, we'll have to turn back."

"I hope it gets stuck so fast they never get it out," said the Madison.

The crossing of the river, which Major White had anticipated with many misgivings, was accomplished with ease; for the bottom was rocky and the banks sloping and firm. There was no sign of the Bansutos, and no attack was made on the column as it wound its way into the forest ahead.

All morning they moved on with comparative ease, retarded only by the ordinary delays consequent upon clearing a road for the big trucks where trees had to be thinned. The underbrush they bore down beneath them, flattening it out into a good road for the lighter cars that followed.

Spirits became lighter as the day progressed without revealing any sign of the Bansutos. There was a noticeable relaxation. Conversation increased and occasionally a laugh was heard. Even the blacks seemed to be returning to normal. Perhaps they had noticed that Orman no longer carried his whip, nor did he take any part in the direction of the march.

He and White were on foot with the advance guard, both men constantly alert for any sign of danger. There was still considerable constraint in their manner, and they spoke to one another only as necessity required.

The noon-day stop for lunch passed and the column took up its snakelike way through the forest once more. The ring of axes against wood ahead was accompanied by song and laughter. Already the primitive minds of the porters had cast off the fears that had assailed them earlier in the day.

Suddenly, without warning, a dozen feathered missiles sped from the apparently deserted forest around them. Two natives fell. Major White, walking beside Orman, clutched at a feathered shaft protruding from his breast and fell at Orman's feet. The askaris and the Arabs fired blindly into the forest, The column came to a sudden halt.

"Again!" whispered Rhonda Terry.

Naomi Madison screamed and slipped to the floor of the car. Rhonda opened the door and stepped out onto the ground.

"Get back in, Rhonda!" cried Baine. "Get under cover."

The girl shook her head as though the suggestion irritated her. "Where is Bill?" she asked. "Is he up in front?"

"Not way up," replied Baine; "only a few cars ahead of us."

The men all along the line of cars slipped to the ground with their rifles and stood searching the forest to right and left for some sign of an enemy.

A man was crawling under a truck.

"What the hell are you doing, Obroski?" demanded Noice.

"I—I'm going to lie in the shade until we start again."

Noice made a vulgar sound with his lips and tongue.

In the rear of the column Pat O'Grady stopped whistling. He dropped back with the askaris guarding the rear. They had faced about and were nervously peering into the forest.
