Before leaving the camp, Mokoum asked the pioneer to lend him his keen-scented dog. The sagacious animal, after scenting a hat belonging to Palander, darted off in a north-easterly direction, whilst his master urged him on by a peculiar whistle. The little troop followed, and soon disappeared in the underwood. All the day the Colonel and his companions followed the dog, who seemed instinctively to know what was required of him. They shouted, they fired their guns, but night came on when they had scoured the woods for five miles round, and they were at length obliged to rest until the following day. They spent the night in a grove, before which the bushman had prudently kindled a wood fire. Some wild howls were heard, by no means reassuring. Hours passed in arguing about Palander, and discussing plans for his assistance. The English showed as much devotion as Strux could desire; and it was decided that all work should be adjourned till the Russian was found, alive or dead. After a weary night the day dawned. The horses were saddled, and the little troop again followed the dog. Towards the north-east they arrived at a district almost swampy in its character. The small water-courses increased in number, but they were easily forded, care being taken to avoid the crocodiles, of which Sir John, for the first time in his life, now saw some specimens. The bushman would not permit that time should be wasted in any attack upon the reptiles, and restrained Sir John, who was always on the _qui-vive_ to discharge a ball. Whenever a crocodile, snapping its prey with its formidable jaw, put its head out of water, the horses set off at a gallop to escape. The troop of riders went on over woods, plains, and marshes, noting the most insignificant tokens: here a broken bough; there a freshly-trodden tuft of grass; or farther on some inexplicable mark; but no trace of Palander. When they had advanced ten miles north of the last encampment, and were about to turn south-east, the dog suddenly gave signs of agitation. He barked, and in an excited way wagged his tail. Sniffing the dry grass, he ran on a few steps, and returned to the same spot. "The dog scents something," exclaimed the bushman. "It seems," said Sir John, "he is on a right track. Listen to his yelping: he seems to be talking to himself. He will be an invaluable creature if he scents out Palander." Strux did not quite relish the way in which his countryman was treated as a head of game; but the important thing now was to find him, and they all waited to follow the dog, as soon as he should be sure of the scent. Very soon the animal, with a loud yelp, bounded over the thicket and disappeared. The horses could not follow through the dense forest, but were obliged to take a circuitous path. The dog was certainly on the right track now, the only question was whether Palander was alive or dead.
