Miss Ada pulled down the volume indicated, blew viciously upon the top edges, and handed it to me. It proved to be part of an almost obsolete Encyclopædia.

"A useful little compendium of knowledge," was Mr. Baxter's comment. "Unfortunately, I have not the set complete—only eight volumes. They go as far as Pocahontas. There are four more, really."

"Prairie Oyster to Zymotic," confirmed the ever-ready Miss Weeks.

"Precisely. You would be surprised at the number of my callers who desire information on matters that come between Prairie Oyster and Zymotic!" The old gentleman sighed. "But where their requirements are limited to the earlier letters of the alphabet, I can usually find a passage which both interests and enlightens them." He glanced at the number on the back of the book. "This is the first volume of the set—A—Byzantium. Many a hungry soul have I fed from it." He turned over the pages. "Addison—Algebra—Archæology—Adenoids— That reminds me, a neighbour is coming in to consult me about adenoids this afternoon. A mother—a woman in quite humble circumstances. I must look up adenoids."

"Isn't that rather trespassing on my department?" I asked.

"Oh, dear! no, sir. All I shall do will be to find the passage relating to adenoids, and read it aloud to Mrs. Caddick."

"Mrs. Caddick? I am treating a child of hers for adenoids at present."

"Quite so, sir. And Mrs. Caddick naturally wishes to know what they are. I shall read aloud to her the scientific definition of the ailment. It is surprising what a comfort that will be to her. Poor soul, she's almost illiterate; and the printed word is a sacred mystery to such!"

"You are an authority on human nature, Mr. Baxter, I perceive."

"You are kind to say so, sir. But I was a mere disciple of the late Archdeacon. It's a strange thing, human nature," he continued pensively. "I have studied it all my life. My recreation is to help it—and it needs all the help it can get. I am at home every evening, and folk look in quite regularly to ask for my guidance on some literary, historical, or scientific point of interest. 'Consulting The Oracle,' they are kind enough to call it. Such visits enable me to gratify at once my hobby and my vanity!" He smiled.
