He paused--after glancing out at the beautiful view over the woodland country dotted with meadow-like pastures in which the ruddy cattle of the county grazed--by the open fireplace with the arms of the Roylands cut in stone beneath the narrow shelf, and the sight of this opening, with the narrow, well-made chimney and some projecting stone blocks from the fire-back, set him thinking. "Fight differently now," he said, as he recalled the object of the furnace before him, and how he had heard or read that it was used on purpose to melt lead ready for pouring down upon the besiegers who might have forced their way across the drawbridge to the portcullis. "Fancy melting lead here to pour down upon men's heads! What wretches we must have been in the old days." He altered his mind, though, directly, as he went back to the stairway. "Perhaps we never did pour any down, for I don't think anybody ever did attack the castle." Thinking he might as well go a little higher, he mounted the spiral instead of descending, the dry elm twigs brought in by the jackdaws which made the untenanted corners their home crackling again beneath his feet. Passing out of the corner turret, which supported a stout, new flag-pole, he was now on the leaded roof of the great square tower, which frowned down upon the drawbridge and gazed over the outer gate-way, in whose tower old Jenkin Bray, the porter, dwelt, and whom Roy could now see sitting beside the modern iron gate sunning himself, his long white hair and beard glistening in the light. There were openings for heavy guns in front here, and a broad, level, projecting parapet with a place where the defenders could kneel, and which looked like a broad seat at the first glance, while at its foot was a series of longish, narrow, funnel-shaped openings, over which the boy stood, gazing down through them at the entrance to the main gate-way, noting how thoroughly they commanded the front of where the portcullis would stand when dropped, and where any enemies attacking and trying to break through would be exposed to a terrible shower of molten lead, brought up from the furnace in the chamber below to pour down upon the besiegers, while those who assailed them were in perfect safety. "Horrid!" muttered Roy; "but I don't know; the enemy should stop away and leave the people in the castle alone. But hot lead! Boiling water wouldn't seem so bad. But surely Master Pawson's friend is wrong; we can't be going to have war here in England. Well, if we do, there's nothing to bring them here."
