Samba at once led the way in a different direction from that lately followed by Jack, saying that he would explain his presence as they went along.

Jack had hardly reached the tent to which he had been decoyed by Elbel's messenger before Samba knew that his uneasy feeling was justified; his master had fallen into a trap. Stealing up close behind Lofembi he had plunged his knife into the man's back, and dashed into the forest. He had no difficulty in escaping from the spot; but the report of the rifle fired after him had reached Elbel's camp below the fort, and Samba found that he had to make a very wide detour to avoid the enemy's scouts. But he managed at last to get into the fort, and implored Barney to send out a party to rescue his captain. Barney was much distressed by the news, but resolutely refused to throw away lives and risk the safety of the fort in a forlorn hope of that kind. All that he would do was to allow Samba, with three other men, Makoko, Lianza, and Lingombela, to follow up Mr. Martindale and Jack, and rescue them if any chance occurred; if not, to see what became of them.

But the four had great difficulty in getting out of the fort undetected; the enemy's vigilance appeared to be doubled, and a full day elapsed before they were able to set off in the track of the prisoners. Failing to overtake the party in the forest before they embarked on the canoes, they had had to cover on foot the long distance for which the Askari were able to use the river, though they shortened the journey to some extent by cutting straight across country when the river wound.

At last, when Samba had all but given up hope, they saw a party of ten Askari coming towards them from down the river. Samba did not suspect at first that these men were connected with those he sought. But keeping well out of sight he tracked them to a spot where a canoe was concealed, and then he guessed at once that the men had been sent back to fetch a canoe left behind for want of sufficient carriers. It would be easy to keep ahead of this party, burdened as they were with the vessel; so Samba and his three companions pushed on, and soon came upon tracks of Mr. Martindale and Jack. They had noticed the newly-made grave with its stone cairn: it had puzzled them, and they did not know it was a grave until Samba pointed out that the litter had ceased to be used: there were no longer the marks of four men walking always at the same distance apart; they then concluded that the elder Inglesa had died.

They came by and by to the place where the party had re-embarked. Samba's only hope of overtaking them now was that they would certainly wait at some part of their journey until they were caught up by the other canoe; and it seemed to him that his expectation was borne out when, scouting ahead of the three, he sighted in the dusk a long canoe lying under the opposite bank in charge of three Askari. He ran back to his companions and told them to hide in the bush; then he returned to the spot, and from a safe concealment prepared to wait and watch. Night fell: the river was too broad for him to see across it; but presently he heard the sound of men approaching the canoe, and soon afterwards voices. Then all was silent. He kept up his watch for some time, half expecting to hear the sound of paddles; but concluding from the continued silence that the men would not move till the morning, he went to sleep in a tree.

Waking before dawn, he resumed his watch. In the early morning he saw eleven men land and make off in two parties into the forest, leaving three men on guard. Instantly he jumped to the conclusion that Lokolobolo had escaped; and a daring scheme suggested itself to him. Returning to his friends, he told them what he had seen, and what he proposed. The four immediately set about building a light raft of bamboos and cane "tie," and when it was finished they carried it some distance along the bank launched it out of sight of the men in charge of the canoe' and punted themselves across to the other side. An hour later only one man remained in the enemy's canoe, and he was a prisoner.

Jack forbore to inquire what had become of the others; Samba merely said that their ammunition had been spoilt by the water. Samba and his companions were Congo natives; free from the restraining influence of the white man, it would be scarcely surprising if they took the opportunity of paying off some of the wrongs they had suffered at the hands of the Askari.

From the prisoner Samba learnt the whole history of the party since the time it left Elbel in the forest. Tying the man up, Samba and his companions at once set to work to find the trail of the fugitive, and of the men who had gone in pursuit. In the morning light it was easy to a practised scout like Samba to find what he sought. He soon discovered that the two parties of Askari had failed to track their quarry, and were going haphazard through the forest. He himself then started to follow Jack up, and his three companions went forth to the canoe to await the return of the enemy. It was unlikely that the two bands would appear at the same time. If they returned separately, the three scouts in ambush would only have to deal with six men or five men, as the case might be. They were still waiting.

What would they do, asked Jack, when the enemy came back?

"Fire upon them from behind the trees," replied Samba. "Three men will certainly be killed; are not the scouts Makoko, Lianza, and Lingombela, three of the best marksmen in Ilombekabasi? If the two or the three men left do not run away, they will fight them. If they run away, they will follow them up and fire at them from behind trees."
