The last time I saw Mr. Sapp, he was standing rather ruefully at the door of Dr. Chloral's office. Dr. Chloral, you remember, is the celebrated dentist of that name, with the striking sign on Cambridge Street, where a gutta-perch mouth, propelled by Cochituate, opens and shuts to slow music, as if it were listening to a lyceum lecture two-thirds done. Fortunately for me, Mr. Sapp did not see me. At that moment he was laying his lines for an inspectorship in the Custom House. He had no letter of introduction which he thought would move Judge Russell, the collector. But he knew, or thought he knew, that Dr. Chloral and Judge Russell were intimate; so he stood at Dr. Chloral's street-door till some patient might come in whom Mr. Sapp could engage to introduce him to the dentist, who in his turn could then introduce him to the collector. An admirable plan! Well, many patients came, you may be sure. Ladies came in carriages with their children, from Chester Square. Students came in the Union cars from Cambridge. Laboring men came up from North Street. Later in the day, toothaching bankers came from State Street, and neuralgic aldermen from City Hall. But hour passed after hour; and no man came whom Mr. Sapp could ask for an introduction to Dr. Chloral. Hour passed after hour. The clock struck three, when Mr. Sapp knew that office hours were over for that day. The hard-worked doctor, released at last, came running down to take his walk before dinner, when lo, one more patient on the stairway! It was poor John Sapp. Failing other introduction, he had, with the promptness of genius, invented a toothache. He met Dr. Chloral, and acted agony so well, that he compelled the doctor to return. "But there's nothing the matter with that tooth, man! It is sound for thirty years." "O," said Mr. Sapp, "I wish I thought so!" "Why, man, I wish it were in my head!" said the doctor. "O," said Mr. Sapp, "I wish it were!" "Well," said Dr. Chloral, "if you say so, here goes"; and in a moment he pulled as honest a tooth as ever ground gristle or tendon. "Now rinse your mouth here, sir; here's a towel, sir; I'm rather late, sir"; and then, as Mr. Sapp loitered,-- "What else can I do for you?" "Could not you,--Dr. Chloral,--could not you write me a line of introduction to Mr. Collector Russell at the Custom House?" "And after all, do you think," said Mr. Sapp,--"after all, Judge Russell appointed a one-legged soldier, who had served in the war; and I lost my tooth for nothing."
