The two flanking companies starting off, those under Chris separating as they rode off until they were as far apart as he had ordered, and then moved forward. When on level ground they went fast, but broke into a walk whenever they came to the foot of rising ground, and when near the top halted, dismounted, and crawled forward. Each man carried a Union Jack about the size of a handkerchief, elastic rings being sewn to two of the corners. When necessary these flags could be slipped over the rifles, and a signal could be passed from one to another along the whole line--to halt by waving the flag, to advance by holding the rifles steadily erect. Other signals were to be invented in the future. Chris took his place in the centre of the line, in readiness to ride to either flank from which a signal might be given. For five or six miles no signs of the enemy could be perceived. Most of the fields were entirely deserted, but round a few of the scattered farmhouses animals could be seen grazing, and these Chris set down as belonging to Dutch farmers who had no fear of interference by the Boers, and were prepared to join them as soon as they advanced. Many of these, indeed, during the past fortnight had trekked north, and were already in the ranks of the enemy. Presently Chris, who was constantly using his glasses, saw the flutter of a flag on a hill away to the left, and a minute later the signal to halt passed along the line. It had been agreed that signalling by shot should not be attempted unless the enemy seen were so far distant that they would not be likely to hear. "What do you see, Brown?" Chris said as he reached the lad who had first signalled. "There are a good many men and animals round a farmhouse about two miles away. The house lies under the shoulder of a hill to the left, I suppose that that is why the others did not see it." Dismounting, Chris crawled forward with the other until he could obtain a view across the country. As Brown had said, the farmhouse stood at the foot of the line of hills they were crossing, and was fully a mile nearer to those on the right flank than to the point from which he was looking at it, but hidden from their view. Bringing his glass to bear upon it, he could distinctly make out that some forty or fifty men were moving about, and that a large quantity of cattle were collected near the house. "It is certainly a raiding party," he said to his companion. "They are too strong for us to attack openly, at least if they are all Boers. It would not do to lose half our number in our first fight. Still, we may be able to frighten them off, and save the farmer, who is certainly a loyalist, and cattle. You gallop along the line as far as it extends and order all to come over to the right. I shall go on at once and get a view of the ground close by. By the time they have all assembled we can see what had best be done."
