The pursuers, who were riding down hill, urged their horses to a gallop. Easing them up the slope, they found when they had reached the top that they had gained nearly half-a-mile on the fugitives, who were apparently unaware of being followed.
From this point onwards the country was a succession of ups and downs like a switchback. The Tubus had disappeared; when next they were sighted, they had almost gained the top of another slope. Royce allowed them to pass from sight over the skyline, then galloped on to gain on them once more.
Hitherto the ground had been fairly open, but it became more wooded as they proceeded. The Tubus were hidden when the pursuers got to the crest of the hill. They gave their horses a breather, and then pushed on at full speed over a rough forest track. Royce was leading with Gamba, Challis and the rest following in single file.
It was impossible to see more than about a hundred yards in front, owing to the winding of the path among the trees. Suddenly the rearmost of the Tubus came into sight about eighty yards ahead. At the same moment he heard the thuds of the pursuers' horses, turned in his saddle, and, shouting with alarm, urged his horse forward.
"After them!" cried Royce, digging his heels into his horse's flanks.
A turn of the path brought the whole nine of the fugitives into view. The path narrowed, so that there was only room for one horseman to ride at a time. The better mounted of the Tubus tried to pass the slower, with the result that some were edged off into the wood on either side, and tried to force their way through the entangling vegetation.
"Never mind about them," cried Royce, who had seen Goruba's huge form galloping ahead of two others.
It was a wild ride. In some places the branches of trees hung down over the path, and the pursuers had to dodge them by bending low on their horses' necks. At other places the path itself was obstructed by fallen boughs and by masses of creepers, so that both pursuers and pursued had the utmost difficulty in avoiding a fall.
Royce, with his eyes fixed on Goruba, narrowly escaped coming a cropper, and was only saved by the sure-footedness of his horse, accustomed to running in this wild forest country. Gambaru was struck from his saddle by an overhanging branch, and Challis, close behind him, pulled up just in time to avoid riding over him.
One of the Tubus riding behind Goruba edged his companion off into the thicket. Royce, close on his heels, shot out his left arm as he passed and threw the man from his seat.
