The next day Jack Barkis's telephone rang more often in an hour than it had ever done before in a month, and every ring meant a call. The first call was from Miss Daisy Peters, and he responded. "I'm so sorry to send for you--er--Doctor," she said--she had always called him Jack before, but now he had come professionally--"for--for--Rover, but the poor dog is awfully sick to-day, and Doctor Pruyn was out of town. Do you mind?" "Certainly not, Daisy," he replied, a shade of disappointment on his face. I am inclined to believe he had hoped to find old Mr. Peters at death's door. "If the dog is sick I can help him. What are his symptoms?" And Miss Peters went on to say that her cherished Rover, she thought, had malaria. He was tired and lazy, when usually he rivalled the cow that jumped over the moon in activity. She neglected to say that she had with her own fair hands given the poor beast a dose of sulphonal the night before--not enough to hurt him, but sufficient to make him appear tired and sleepy. "I must see my patient," said the Doctor, cheerfully. "Will he come if I whistle?" Miss Peters was disinclined to accede to this demand. She was beginning to grow fearful that Jack would see through her little subterfuge, and that the efforts of the S.F.M.E. would prove fruitless. "Oh," she demurred, "is that--er--necessary? Rover isn't a child, you know. He won't stick out his tongue if you tell him to--and, er--I don't think you could tell much from his pulse--and--" "I'd better see him, though," observed Jack, quietly. "I certainly can't prescribe unless I do." So Rover was brought out, and it was indeed true that his old-time activity had been superseded by a lethargy which made the wagging of his tail a positive effort. Still, Doctor Barkis was equal to the occasion, prescribed for the dog, and on his books that night wrote down a modest item as against Mr. Billington Peters and to his own financial credit. Furthermore, he had promised to call again the next day, which meant more practice. On his return home he found a hurry call awaiting him. Miss Betsy Barbett had dislocated her wrist. So to the Barbett mansion sped Doctor Barkis, and there, sure enough, was Miss Barbett apparently suffering greatly. "Oh, I am so glad you have come," she moaned. "It hurts dreadfully, Jack--I mean Doctor."
