To our right as we leave Temple Bar rises the splendid pile of the new Law Courts, and on we go between close-packed lines of shops and theatres until we come out into Trafalgar Square, the central point of London. Here is a great open space where fountains quietly play and a lofty column rises, the latter crowned with a statue of our sailor hero, Nelson. At the upper end of the Square stands the National Art Gallery, where some of the finest pictures in the world may be seen; but we must come another day to look at them, for our bus is still rolling westward. We get a glimpse at Pall Mall, the region of club-land, and soon enter Piccadilly, one of London's most beautiful and famous streets. We pass the doors of the Royal Academy, and then a pleasant park opens to our left, the Green Park, while on our right runs a continuous line of mansions, shops, and clubs, until the bus pulls up at Hyde Park Corner, and we have reached the great park. On a fine summer day Hyde Park offers one of the most wonderful scenes in London. A constant stream of splendid carriages, drawn by magnificent horses, pours into the park and moves round and round the Drive and "The Row," with its riders, is even more interesting. Rotten Row is a long, broad, tan-covered ride, where horsemen and horsewomen trot and canter to and fro. Finer horses and riders are not to be found. On a morning when the Row is fairly full, it is delightful to spend an hour or so, seated on one of the green chairs in shade of an elm or lime, watching the riders. Here comes an old gentleman on a stout cob. They pound steadily past, and now three or four young people mounted on tall, lively horses dash past at a gallop, chatting merrily as they go, and then there is a swift scurry of ponies, as some children dart along, racing each other up to the Corner, where all turn and come back. Perhaps in an afternoon you may go in through the great gates at Hyde Park Corner and find the carriages drawn up in lines, and a feeling of excitement and expectation in the air. A clear track is being kept. For whom? For the Queen. She is coming up now from Buckingham Palace to drive in the Park. Suddenly there is a brilliant flash of colour as servants in royal liveries of glowing scarlet come into sight. Hats fly off as the royal carriage passes, drawn by splendid chestnuts, and there is the Queen, bowing and smiling at the people who greet her as she drives into the Park. IN LONDON TOWN--III. Now that we have seen the Queen pass by, we will go and look at her home in London. Buckingham Palace is not far from Hyde Park Corner, and when we reach it we see a big, rather dull-looking building, with a courtyard before it, and red-coated soldiers marching up and down on guard. This palace of the King and Queen is, in truth, not very handsome outside, but it is very splendid within, its fine rooms being adorned with the paintings of great artists.
