"Time enough, lad, time enough," he had said, when the lad had made his petition to do so. "You are not strong enough, yet, to hold your own against one of the Bairds' moss troopers, should it come to fighting. In another couple of years it will be time enough to think of your going on such an excursion as this. You are clever with your arms, I will freely admit; as you ought to be, seeing that you practise for two hours a day with the men. But strength counts as well as skill, and you want both when you ride against the Bairds; besides, at present you have still much to learn about the paths through the fells, and across the morasses. If you are ever to become a leader, you must know them well enough to traverse them on the darkest night, or through the thickest mist." "I think that I do know most of them, Father." "Yes, I think you do, on this side of the border; but you must learn those on the other side, as well. They are, indeed, of even greater importance in case of pursuit, or for crossing the border unobserved. Hitherto, I have forbidden you to cross the line, but in future Mat Wilson shall go with you. He knows the Scotch passes and defiles, better than any in the band; and so that you don't go near the Bairds' country, you can traverse them safely, so long as the truce lasts." For years, indeed, Oswald, on one of the hardy little horses, had ridden over the country in company with one or other of the men; and had become familiar with every morass, moor, fell, and pass, down to the old Roman wall to the south, and as far north as Wooler, being frequently absent for three or four days at a time. He had several times ridden into Scotland, to visit the Armstrongs and other friends of the family; but he had always travelled by the roads, and knew nothing of the hill paths on that side. His life had, in fact, been far from dull, for they had many friends and connections in the villages at the foot of the Cheviots, and he was frequently away from home. His journeys were generally performed on horseback, but his father encouraged him to take long tramps on foot, in order that he might strengthen his muscles; and would, not infrequently, give him leave to pay visits on condition that he travelled on foot, instead of in the saddle.
