So the Widow Pickle peered closely through her glasses and saw that there was a name printed in small shining letters on one end of the boat. "The Gee-Whiz Submarine Express!" cried the Widow. "But, alack! how small it is. Why, it is not as long as my foot, and I was always thought in my time to have a very small foot, too!" The Private Secretary smiled in a knowing manner. "Perhaps, mamma," said Zuzu, "you have overlooked something in some other box." "Zuzu, you have a good mind for one so young," said his mother. "I will look in the cupboard again." So again she began rummaging around, and at length she found another box, a square one, covered over with dust, showing that it had not been opened for a long time. The first box had held a pale-blue powder, but this one was filled nearly to the lid with a light-green powder. On the top of this box, written in the hand of Aurelius Pickle, was the inscription, "Magic Powder of Gee-Whiz." When the Widow Pickle saw this, she gave an exclamation of joy. [Illustration] [Illustration] CHAPTER VI THE JOURNEY THROUGH THE AIR "Hurry, hurry, mamma!" cried the Twins. "Let us go." "But how can we go?" asked the Widow Pickle of the Private Secretary, as she stood holding the second box of powder in her hand. "I suggest, madam," said the Private Secretary, "that you might put a little of the first powder, the blue one, in the engine." The Widow Pickle placed a pinch of the pale-blue powder upon a certain portion of the little boat, and, to her great surprise, it began to grow before her eyes. It grew and it grew, slowly but steadily, until it was large enough for either of the Twins to get into. In a moment more it would have been too large to pass out of the window; and as the Widow Pickle saw this, she was about to brush off the rest of the powder. "Stop!" cried the Private Secretary. "The window will not make the slightest difference in the world. Quick, madam! Get in with the second box, or it will be too late." Indeed, the engine inside the boat now began to churn, and a strange, brilliant sort of blue smoke began to hiss at the spouts near the wheel. The boat, for such it can be called, began to crawl on its feet across the floor toward the window. The Private Secretary grasped the Enchanted Banjo and with a bound sprang into the boat. The Widow, holding on to the remaining box of powder, and grasping the Twins also with the other hand, sprang aboard quickly. The Private Secretary then snapped down the glass all around. To her great surprise, the Widow Pickle found the boat quite large enough for all four of them, and even as she settled down comfortably in her seat the boat rose slowly and, with a slight hissing of the strange blue steam at the wheel, it passed directly out and through the window, just as though it were not there, and sailed off across the tops of the tall buildings toward the sea. "Oh, Mr. Secretary," cried the Widow Pickle, "how very much startled I am!"
