"Putting on a disguise." "What for?" Bob told him. "I want to go with you," exclaimed Hugh eagerly. "Two would be better than one anyway." "Where are you going to get a disguise?" "I'll borrow part of yours. You can certainly spare enough of those whiskers to make me a mustache anyway." "You ought to have another hat." "You can lend me an old cap, can't you? I've got on the oldest suit I own." Bob brought out the glue pot and with Hugh's assistance was soon adorned with a set of black whiskers and a mustache. His hair did not match at all, but as he expected to wear a hat pulled far down over his eyes that fact did not make much difference. He put on the hat, and wearing his old clothes and a sweater looked at himself in the mirror. "Whew," he exclaimed, "I'm certainly a hard looking character." "You certainly are," agreed Hugh, "and you look about forty years old." "All the better," said Bob. "Now let's get you fixed up." With what was left of Bob's whiskers a small black mustache was twisted into shape and glued to Hugh's upper lip. It was remarkable to see what a great change in his appearance it made. "When we take these things off, all the skin on our faces will come too," said Hugh inspecting himself in the mirror. "Don't you care," exclaimed Bob. "What we're interested in at present is to have them stay on to-night. How about a hat for you now?" He rummaged around on the closet shelf and produced an old cap and a derby. "Put the derby on, Hugh," he urged. "You'll look just like Charlie Chaplin." "That wouldn't do, I'm afraid," laughed Hugh. "I'd have too big a crowd following me." "Turn up the ends of your mustache and you'll look like the kaiser." "Not for me!" exclaimed Hugh hastily. "I don't want to look like anything German. I'll wear the cap, I guess. I think that's better than the derby." At that moment Mr. Cook appeared upon the scene. He stood and looked at the two boys approvingly. "Well," he said, "you certainly look like a couple of tough customers all right. I'm glad you're going along, Hugh; I think two will be better than one." "Is Lena still here?" asked Bob. "Still here," said his father. "She's getting ready to leave though and you two had better be prepared." "Where's Heinrich?" "He's due in about five minutes." "You'd better watch him, father," warned Bob. "Don't worry about that," said Mr. Cook soberly. "I suppose that you two 'things' will come to the factory later. I expect to be there all night." "We'll try to get there," said Bob. "We'll keep track of Lena as long as we can, and if it's possible we'll report to you at the office." "Good," exclaimed Mr. Cook. "Don't forget to be very careful, and don't get into trouble if you can help it." "We'll do our best," Bob promised. CHAPTER XXI ON THE STREET
