"Well, a neighbor acrost the street come over to-day and took 'em away. She didn't know but it might be dip'thery." "Have you had any diphtheria in your neighborhood?" "Well, yes; the caretaker of our flats down on the first floor of the next house lost a child last week by a belief in dip'thery. The neighbor acrost the street thought Tommy might have got it, but we didn't believe it. But it made mother kind of uneasy, and she wanted to see you or a doctor to-night. For my part, I knew that it was the talk of the infant-class teacher that was at the bottom of it, dip'thery or not. Sin oughtn't to be mentioned to a child. It's likely to break out into a belief about sickness." Phillida's spirits suddenly sank to zero. Alarm at the responsibility she had taken got the better of her faith by surprise, and she said: "Mr. Martin, get a doctor. It may be diphtheria." "Why, what if it is?" said Mr. Martin. "It's better to treat it on a spiritual plane. No, I'm not a-going back on my faith in the very words of the Bible." "But, Mr. Martin, I don't feel sure enough to want to be responsible for Tommy's life. You must get a doctor as you go home. You go almost past Dr. Beswick's in Seventeenth street." "No, I won't do that; I'd made up my mind already that your treatment wa'n't thorough enough. You haven't had the experience; you haven't studied the nature of disease and the cor-what-you-may-call-it between sin and sickness. I'll call Miss Bowyer if Tommy don't mend before morning." Just then it began to rain again. The sudden plash of the downpour and Phillida's instinctive impulse to get quickly under shelter interrupted the conversation. A minute later Miss Callender was standing in the vestibule with a weeping umbrella in her hand, while she heard Mr. Martin's retreating footsteps, no whit hurried by the fitful gusts of rain, or the late hour, or the illness at home. She thought of running after him, but of what use would that be, seeing his obstination against treating diseases on the mortal plane? She would have liked to go home with him and beg the mother to send for a doctor; but she could not feel sure that this would serve the purpose, and while she debated the rain came on in driving torrents, and the steady beat of Mr. Martin's steps was lost in the distance and the rush of waters. In vain she told her mother that the child did not seem very ill, in vain she told herself during the night that Tommy had only an ordinary cold. She was restless and wakeful the night long; two or three times she lighted a match and looked at the slow-going clock on the mantelpiece.
