It was all new to Edith and Adelaide, so Tom took them through some of the old class-rooms, where many celebrated men had learned their lessons. The rough, wooden benches and desks had been hacked and cut up by the knives of schoolboys for many hundred years. It used to be the fashion for the boys to cut their names somewhere on the oak-panelled walls of their schoolrooms, and many names that have since become famous can be seen there to-day. The boys liked to do it all the more, because it was forbidden, but gradually it became the custom, and the proper thing to do. After Tom had duly impressed the glories of his school upon his sister and cousin, the whole party set out for Windsor Castle, just across the river from Eton. In a few minutes they were climbing the hill on which the castle stands, and the carriage stopped at the big entrance gate, on either side of which stands a sentry in a bright red coat and a great bearskin helmet on his head. [Illustration: WINDSOR CASTLE] "Now, my dears, you are really inside the king's home," said Colonel Howard, as with some other visitors they followed the guide through the handsome rooms, with their elegant furniture and valuable pictures. From the windows was a fine view extending many miles over the great park which surrounds the castle. "On certain days of the week," said Colonel Howard, "a band plays on the terrace below, and then the grounds and terrace are free to all who wish to come, while the Royal Family often sit at these windows and enjoy the music." They also visited the beautiful chapel, where the king and his family attend service when they are at the castle. Soon our party came to meet the carriage again outside the great gateway. "Drive to the 'White Swan,' John," said Colonel Howard, "we are going to lunch there." "That's good," said Tom. "It's a jolly nice place; they will give us a good dinner. Look, papa," he continued, excitedly, "there is Prince Eddie and his brother in that carriage coming toward us. I knew they were staying at 'Frogmore House.'" The two boy princes, manly-looking young boys, dressed in sailor suits, were chattering gaily with their tutor, who accompanied them, and smilingly returned the bows of Colonel Howard's party as they passed. They are the two oldest sons of the Prince of Wales; they are fine-looking little fellows, and enjoy nothing better than their home life in the country, cycling around Windsor Park, or fishing and boating on the river. Our little party enjoyed a bountiful dinner in the cool dining-room of the "White Swan Inn," with its dark, oak-panelled walls, and big sideboard, set out with fine old silver and china. The solemn, smooth-faced old waiter deftly served them. First they had a delicious fried sole, and then the dish without which no English person thinks dinner is complete,--a big joint of good English roast beef, which as a matter of fact mostly comes from Scotland.
