As the boys started to make their way up the beach a trim figure with neatly waxed black mustaches, almost extinguished in a huge pith helmet and dressed in white duck with a red sash about the waist, emerged from the nearest house and hastened toward them.

"Welcome to Africa!" cried the newcomer as he approached and who, as Frank at once guessed, was M. Desplaines himself. "Come with me to the house and make yourselves at home."

The boys shook hands warmly with the little Frenchman who seemed so hospitably inclined and followed him eagerly toward the whitewashed house from which he had emerged.

"I would have been at the steamer to meet you," he exclaimed apologetically; "but she got here a day ahead of time and I was not prepared."

Inside the house, which was delightfully cool and darkened by jalousies from the glaring heat outside, the young adventurers were introduced to Madame Desplaines and two little girls, who constituted the family of the consular agent, who also kept the general supply store at Assini.

After dinner that evening, M. Desplaines talked long and earnestly to the boys. Of the real object of their mission, he had of course no knowledge. That was kept a secret even from Barr's intimates. There was too much at stake to let it leak out. His idea was the boys had come on a hunting and exploration, much of which was to be performed by aeroplane. He informed the boys that, acting on cabled instructions, he had laid in a good supply of gasoline by the last steamer from Sierra Leone and that arrangements for a train of carriers and for boats up the river had been made. There was a wheezy steam launch belonging to the trading post which would tow the boats up the Bia River as far as they desired. The Kroomen the boys engaged would take them to that point would then be abandoned, as they refused to go far from the coast. Such was the outline of M. Desplaines' conversation with the travelers.

The evening was far advanced when already the little party was ready for bed and already their imaginations had been fired by the tales that the consular agent had told them of the interior of the wild Bambara country. As they were saying good night to their hospitable host and hostess, there was a knock at the door. In response to M. Desplaines shouted: "Come in," a tall coal-black figure stalked into the lamp-light. The glow shone warmly on his black skin and lit up the mighty muscles that played beneath it. The strength of the man was evidently tremendous. The boys, to their surprise, recognized him at once, as the rescuer of Frank's opera-glasses. He paid no attention to Desplaines or his family, but walked straight up to Frank.

"Hi boss, you go hunt, you go far into land of Bambara," he said, raising his mighty arm and pointing to the northeast.

Frank nodded.

It was a strange scene. The boys and Ben in their hunting costumes and stout boots, M. Desplaines, short and inclined to be fat and as neatly barbered and tailored as if he had just stepped off the boulevards, Madame Desplaines and her little girls in cool, white frocks—and in the center of the group—dominating it by his impressive manner and mighty form—the huge, ebony Krooman.
