"It seems hardly likely it was the water," he said, "although from what I recall of my chemistry it is distinctly possible. Springs have been known to change their character, and the coincidence—the dog and the water—is certainly startling. Still, as nobody feels ill—"

But they weren't sure they didn't. The bishop said he felt perfectly well, but he had a strange inclination to yawn all the time, and Mrs. Biggs' left arm had gone to sleep.
