"Somebody who wants to disguise their writing," remarked Tom, as he tore it open. A look of surprise came over his face.
"Look here! Mr. Whitford," he cried. "This is the work of the smugglers all right!"

"If you know what is good for you, Tom Swift, you had better clear out. If you don't your airship will burned, and you may get hurt. We'll burn you in mid-air. Beware and quit. You can't catch us.
"Ha! Warned away!" cried Tom. "Well, it will take more than this to make me give up!" and he crumpled the anonymous warning in his hand.
