"Well, good-night, Sergeant," exclaimed Mr. Cook, shaking hands with the doughty officer. "I'm sorry Hoffmann was mixed up in this business, but I'm glad it's all cleared up. I hope we'll have no more trouble." "Ye won't, as long as yez have two young fellers like Bob and Hugh working for yez," exclaimed Riley. "The United States needs boys like that; this war is going to be a long and hard one in my opinion." "I'm afraid so," Mr. Cook agreed. "I guess we'll come out all right if we all work hard and stick together though." "That's it," exclaimed Riley. "We must all work together. Our personal feelings don't count. It's what our country needs." He said good night all around and went out. * * * * * The next morning Bob was out in the yard inspecting a plot of ground where he was going to have a garden. He could not enlist, but he was going to "do his bit" by raising a few vegetables, and thus help to supply the country with its necessary food. He heard a step behind him and turned to see Frank Wernberg. Frank held out his hand. "Shake hands with me, Bob," he exclaimed. "I want to tell you that I was wrong about that the other day, and you were right." Bob responded heartily. "Yes," said Frank. "I was dead wrong. I had thought from the way father talked that he was pro-German, but I found out that he wasn't at all. When it came to a question of deciding between his country and Germany there was never any doubt about where he stood." "I know that, Frank," said Bob. "I wish every one of German birth or descent over here felt the same way." "I think most of them do," said Frank. "I guess that's right," Bob agreed. "Look at Lena and Heinrich." "Well, all I wish now," exclaimed Frank, "is that we could enlist." "So do I," cried Bob enthusiastically. "Wouldn't it be wonderful if you and Hugh and I could enlist and go together?" The new adventures are recorded in the story entitled, BOB COOK AND THE GERMAN AIR FLEET. THE END
