In the hasty description of Boscobel House, previously given, it was remarked that the most singular feature of the edifice was a huge projecting chimney-stack. A very extraordinary chimney it was, for it had as many as seven small windows, or apertures, within it, placed at various heights, the two lowest of the openings being about eight or nine feet from the ground. Viewed at the side it could be seen that the chimney-stack, which rose considerably above the roof, formed part of a projecting wing of the house, and that there must be something peculiar in the construction of the funnels. Altogether it had a strange, mysterious look, and suggested the idea that the builder must have been slightly crazed. Yet, odd as it was, the huge, heavy, fantastic chimney harmonised with the rest of the structure. The reader will have already surmised that within this chimney-stack a secret hiding-place existed; the entrance to it being from a closet connected with a bedroom on the first floor--as will be more particularly described hereafter--while there was an outlet into the garden through a little postern, completely screened by ivy. Since the king's arrival at Boscobel, the chimney-stack had acquired a new interest in Trusty Dick's eyes, and being now left in the garden to keep watch, he scrutinised it with an anxiety such as he had never heretofore felt, peering up at the narrow slits of windows, and stooping down to ascertain that the postern was completely hidden by the ivy. Never before had he doubted the security of the hiding-place, but misgivings now came over him. What if a careful examination of the chimney, outside and inside, should be made while the king was concealed therein? Discovery would then be inevitable. Pondering upon the matter, Dick quitted the garden, and in another instant was among the noble old trees growing near the house. An idea had taken possession of him, and he walked on till he reached a giant oak which, standing a little clear of its fellows, was able to spread abroad its mighty arms. This was the tree he sought. Though it must have been centuries old, the oak seemed in full vigour, and had suffered very little from decay. Its trunk was enormous. It had not, however, grown to a great height, but had spread laterally. Dick examined this ancient oak very carefully--walked slowly round it--looked up at the bushy central branches, and seemed perfectly satisfied with his scrutiny. "This is the tree for the king to hide in!" he mentally ejaculated; "this is the tree!--the best in the whole forest. No one could discover him among those thick branches." He was still examining the oak when he was roused by Major Careless, who had been searching for him, and having found him, called out, "What ho! Dick--have you deserted your post?"
