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. 24"Oh, Mr. Secretary," cried the Widow Pickle, "how very much startled I am!" 24 "Madam," replied the Private Secretary, "there is no need to be startled.

"You would better not try to find out," said the Private Secretary, smiling. "But now, madam,
