Without a word Rob followed him. There was no time to question such a course, and already Macaulay was within a mile of them. But when he saw them heading for the tents in the glen below he paused, as well he might, for the sight of two Jacobite rebels scampering towards an English camp was sufficiently arresting. The Highlanders with him, who had no wish for nearer acquaintance with red-coated soldiery, slackened their pace too, and, dropping below the sky-line, became invisible in the heather. On ran Muckle John, and behind him Rob, until an English sentinel raised his musket and called to them to halt. The boy glanced anxiously at his companion's face. But he gathered nothing there. There was certainly no sign of fear. "Who goes there?" cried the sentry. Quite quietly Muckle John thrust a hand into his great-coat pocket. "Here is my passport," he replied, "and this is my guide. I am Captain Strange, on special duty in the west," and he handed over a document to the man, who read it slowly, and then saluting, stood at attention until they had passed. When they were about twenty yards distant, however, Muckle John spoke in a low voice to Rob. "Look up the hill," he said, "and tell me if Macaulay is coming down." But there was no one to be seen, and on learning that, Muckle John gave a great sigh as though he were vastly relieved. They neared the tents and were walking on, when an officer rose to his feet and stopped them. "Who are you?" he asked, "and what kind of Highland wild-cat is that?" pointing with the end of his sword at Rob. "I am Captain Strange," said Muckle John. "Strange," echoed the man, who seemed a good-humoured fellow, greatly bored with sitting among the hills. "Oh yes, I ken ye by name, and I am Captain Campbell, at your service. Come and have a crack inside," and he made to enter his tent. With a momentary hesitation Muckle John followed him, but first of all he took one swift sweeping glance over his shoulder at the hillside. Then, seating himself within, he fell into conversation, while Rob waited outside the tent, watching the soldiers standing at their posts, or marching up and down amongst the heather. All the time a curious presentiment of fear grew heavy upon him, which the silent day only intensified. "I take it you were at Culloden," said Captain Campbell; "that must have been a poorlike affair." "None so poor," said Muckle John; "where there are starving men and bickering chiefs you don't look for much resistance, but they broke two lines, sir." "Did they so? It is evident the Argyll men were not in prominence." "No," replied Muckle John drily, "the Campbells were employed in pulling down walls." The other eyed him uncertainly. He felt the sting under his words. "If the business had been left to the Duke," said he, "there would have been no call for levies from the Low Country."
