The armor, of course, varied very much in its character and fashion, according to the age in which the monarch who wore it lived; and it was very interesting, in walking down the hall, to see how military fashions had changed from century to century, as shown by the successive changes in the accoutrements which were observed in passing along the line of kings. There were many suits of armor that were quite small, having been made for the English princes when they were boys. Rollo amused himself by imagining how he should look in one of these suits of armor, and he wished very much that he could have an opportunity of trying them on. In one place there was a battery of nine beautiful little cannons made of brass, each about two feet long, and just about large enough in caliber for a boy to fire. These cannons, which were all beautifully ornamented with bas reliefs on the outside, and were mounted on splendid little carriages, were presented to Charles II. when he was a boy; and I suppose that he and his playmates often fired them. There were a great many other strange and curious implements of war that have now gone wholly out of fashion. There were all kinds of matchlocks, and guns, and pistols, of the most uncouth and curious shapes; and shot of every kind--chain shot, and grape shot, and saw shot; and there were bows and arrows, and swords and halberds, and spears and cutlasses, and every other kind of weapon. These arms were arranged on the walls in magnificent great stars, or were stacked up in various ornamental forms about pillars or under arches; and they were so numerous that Rollo could not stop to look at half of them. After this the yeoman of the guard led his party to a great many other curious places. He showed them the room where the crowns and sceptres of the English kings and queens, and all the great diamonds and jewels of state, were kept. These treasures were placed on a stand in an immense iron cage, so that people assembled in the room around the cage could look in and see the things, but they could not reach them to touch them. They were also taken to see various prison rooms and dungeons where state prisoners were kept; and also blocks and axes, the implements by which several great prisoners celebrated in history had been beheaded. They saw in particular the block and the axe which were used at the execution of Anne Boleyn and of Lady Jane Grey; and all the party looked very earnestly at the marks which the edge of the axe had made in the wood when the blows were given. The party walked about in the various buildings, and courts, and streets of the Tower for nearly two hours; and then, bidding the yeoman good by, they all went away. "Now," said Rollo, as soon as they had got out of the gate, "which is the way to the Tunnel?"
