Driven out by her former protector, the janitor of Harvard Hall, Sarah, Yard eat and mouser extraordinary, is now anticipating a blessed event under the sponsorship of the Stoughton janitor. Sarah has been biologically different of late and a brood of kittens is expected within the next two weeks. Her former protector drove her out, not desiring the confusion and flurry always attendant up on childbirth. The Stoughton janitor, however, a farsighted and economically-minded man, has plans in store for the brood. He will expect them to earn their unkeep by being rented out for mousing throughout the Yard.
