"Well," he explained, "I fancy this one was originally white. Somebody probably dyed it green."

"But who on earth would be silly enough to do such a thing?"

His ears grew red--he felt them doing it.

After a moment she said: "I am glad you told me that you, too, saw this unspeakable mouse. I have decided to write to the owners of the house and request an immediate investigation. Would--would it be too much to ask you to write also?"

"Are you--you going to write?" he asked, appalled.

"Certainly. Either some dreadful creature here keeps a bird store and brings home things that escape, or the house is infested. I don't care what the janitor says; I did hear squeals and whines and whimpers!"

"Suppose--suppose we wait," he began lamely; but at that moment her blue eyes widened; she caught him convulsively by the arm, pointing, one snowy finger outstretched.

"Oh-h!" she said hysterically, and the next instant was standing upon a chair, pale as a ghost. It was a wonder she had not mounted the dresser, too, for there, issuing in creepy single file from the wainscoting, came mice--mice of various tints. A red one led the grewsome rank, a black and white one came next, then in decorous procession followed the guilty green one, a yellow one, a blue one, and finally--horror of horrors!--a red-white-and-blue mouse, carrying a tiny American flag.

He turned a miserable face toward her; she, eyes dilated, frozen to a statue, saw him advance, hold out a white wand--saw the uncanny procession of mice mount the stick and form into a row, tails hanging down--saw him carry the creatures to a box and dump them in.

He was trying to speak now. She heard him stammer something about the escape of the mice; she heard him asking her pardon. Dazed, she laid her hand in his as he aided her to descend to the floor; nerveless, speechless, she sank into the big chair, horror still dilating her eyes.
