First, there was a flower garden,--centuries ago cultivated as now, but then only for the inmates of the castle. Here was also a museum, containing many articles once used in the castle. We did not get up enthusiasm enough to go in; and now content ourselves by saying, "Where ignorance is bliss, 'tis folly to be wise." Beyond another gate, we find ourselves in a closely cropped sheep-pasture. No lawn in our Boston suburbs equals this carpet of green, acres in extent. To our left, five hundred feet away, were the ruins observed before. We don't discount this beauty even now, and we never will. Put those ruins in Brookline or Brighton, and we'd stand our ground even with Englishmen. But what shall we say about the ruins of the castle itself,--there on our right, two hundred feet away? This is Cæsar's Tower. Square in plan, the surface is broken with piers and vertical projections of varying width; the top is perhaps sixty feet from the ground, and made irregular by its decay. It is roofless, of course, and has walls sixteen feet thick at the bottom; half the surface is covered with dark-leaved ivy, precisely such as is grown in our houses. We go nearer; now on our right, two hundred feet on our front, and left, leaving a half enclosed square, are other portions of this great castle. What variety of outline! What solidity! There are patches of ivy fifty feet square. Measuring a single trunk, conformed to the crevices of the wall, we found it to be 3 feet 10 inches wide, and 16 inches thick at the centre, decreasing to a thickness of 3 inches at the edges. We should have been unable to believe this story, had it been told by others, and will not find fault with any one who now doubts our accuracy. The castle was founded by Geoffrey de Clinton, treasurer to Henry I.; and in 1286 it was the place of a great chivalric meeting, at which it is said, "silks were worn for the first time in England." The very gorgeous entertainment given here in 1575, to Queen Elizabeth, is immortalized by Scott in "Kenilworth." Of the original castle, all now remaining is the corner tower. All else, though to all appearances as old looking, is of later date. The hall erected by John of Gaunt, who died Feb. 3, 1399, is 86 feet long and 45 wide, having mullioned windows on each side, and large fireplaces at each end.
