"It's only a sham battle!" said Mr. Bobbsey. "No one is being hurt, for they are using blank cartridges. It must be that the soldiers are practicing so as to know how to fight if a real war comes. It is only a sham battle." The cannons roared, the rifles rattled and flashes of fire and puffs of smoke were on all sides. "Oh, look at the horses--the cavalry!" cried Harry, as a company of men, mounted on horses, galloped toward some of the soldiers, who turned their rifles on them. Then one man, on a big black horse, left the main body and came straight on toward Mr. Bobbsey, Uncle Daniel, and the two boys. "We'd better look out!" cried Bert "Maybe he wants to capture us!" CHAPTER XI MOVING PICTURES The man on the black horse continued to ride toward the two boys, Uncle Daniel and Mr. Bobbsey. Behind him more men on horses rushed forward, but they were going toward some soldiers on foot, who were firing their rifles at the "cavalry," as Harry called them, that being the name for horse-soldiers. "Oh, look, some of the men are falling off their horses!" cried Bert "Maybe they are hurt," Harry said. "No, I guess it's only making believe, if this is a sham battle," went on Bert. By this time the man on the black horse was near Mr. Bobbsey. "You had better stand farther back, if you don't mind," he said. "Why, are we in danger here?" asked Uncle Daniel. "Well, not exactly danger, for we are using only blank cartridges. But you are too near the camera. You'll have your pictures taken if you don't look out," and he smiled, while his horse pawed the ground, making the soldier's sword rattle against his spurs. "Camera!" exclaimed Mr. Bobbsey. "Is someone taking pictures of this sham battle?" "Yes, we are taking moving pictures," replied the soldier. "The man with the camera is right over there," and he pointed to a little hill, on top of which stood a man with what looked like a little box on three legs. The man was turning a crank. "Moving pictures!" repeated Uncle Daniel, looking in the direction indicated. "That's what this sham battle is for," went on the soldier who sat astride the black horse. "We are pretending to have a hard battle, to make an exciting picture. Soon the camera will be pointed over this way, and as it wouldn't look well to have you gentlemen and boys in the picture, I'll be obliged to you if you'll move back a little." "Of course we will," agreed Mr. Bobbsey. "Especially as it looks as though the soldiers were coming our way." "Yes, part of the sham battle will soon take place here," the cavalryman went on. "Come on back, boys!" cried Uncle Daniel, "We can watch just as well behind those trees, and we won't be in the way, and have our pictures taken without knowing it." "Yes, and we won't be in any danger of having some of the paper wadding from a blank cartridge blown into our eyes," added Mr. Bobbsey. "Say, this is great!" cried Harry. "I'm glad we came." "So am I," said Bert
