BOB COOK AND THE GERMAN SPY

CHAPTER I

WAR IS DECLARED

"Well," said Mr. Cook, "I see that the United States has declared war on
Germany. I am glad of it, too."

"Why, Robert!" exclaimed Mrs. Cook. "How can you say such a thing? Just think of all the fine young American boys who may be killed."

"I realize all that," said her husband. "At the same time I agree with President Wilson that the German Government has gone mad, and as a civilized nation it is our duty to defend civilization. The only way left for us is to go in and give Germany a good beating."

"And I shall enlist and get a commission," cried Harold, their eldest boy. "I am twenty-three years old. I have been at Plattsburg two summers, and I have done a lot of studying; I know I can pass the examinations."
