The dining-room into which the guest was conducted betrayed a feminine touch not visible in the smoke-dimmed quarters of shop and cabinet. At the windows were curtains of laughing chintz and pots of pink geranium. The table, under a drop-light in a flame-coloured silk screen, was brightly set with silver and blue china. In a cut-glass decanter sparkled a ruddy brown wine. The edged tool of Advertising felt his spirits undergo an unmistakable upward pressure.

"Sit down, sir," said Mifflin, lifting the roof of a platter. "These are eggs Samuel Butler, an invention of my own, the apotheosis of hen fruit."

Gilbert greeted the invention with applause. An Egg Samuel Butler, for the notebook of housewives, may be summarized as a pyramid, based upon toast, whereof the chief masonries are a flake of bacon, an egg poached to firmness, a wreath of mushrooms, a cap-sheaf of red peppers; the whole dribbled with a warm pink sauce of which the inventor retains the secret. To this the bookseller chef added fried potatoes from another dish, and poured for his guest a glass of wine.

"This is California catawba," said Mifflin, "in which the grape and the sunshine very pleasantly (and cheaply) fulfil their allotted destiny. I pledge you prosperity to the black art of Advertising!"

The psychology of the art and mystery of Advertising rests upon tact, an instinctive perception of the tone and accent which will be en rapport with the mood of the hearer. Mr. Gilbert was aware of this, and felt that quite possibly his host was prouder of his whimsical avocation as gourmet than of his sacred profession as a bookman.

"Is it possible, sir," he began, in lucid Johnsonian, "that you can concoct so delicious an entree in so few minutes? You are not hoaxing me? There is no secret passage between Gissing Street and the laboratories of the Ritz?"

"Ah, you should taste Mrs. Mifflin's cooking!" said the bookseller. "I am only an amateur, who dabbles in the craft during her absence. She is on a visit to her cousin in Boston. She becomes, quite justifiably, weary of the tobacco of this establishment, and once or twice a year it does her good to breathe the pure serene of Beacon Hill. During her absence it is my privilege to inquire into the ritual of housekeeping. I find it very sedative after the incessant excitement and speculation of the shop."

"I should have thought," said Gilbert, "that life in a bookshop would be delightfully tranquil."

"Far from it. Living in a bookshop is like living in a warehouse of explosives. Those shelves are ranked with the most furious combustibles in the world—the brains of men. I can spend a rainy afternoon reading, and my mind works itself up to such a passion and anxiety over mortal problems as almost unmans me. It is terribly nerve-racking. Surround a man with Carlyle, Emerson, Thoreau, Chesterton, Shaw, Nietzsche, and George Ade—would you wonder at his getting excited? What would happen to a cat if she had to live in a room tapestried with catnip? She would go crazy!"

"Truly, I had never thought of that phase of bookselling," said the young man. "How is it, though, that libraries are shrines of such austere calm? If books are as provocative as you suggest, one would expect every librarian to utter the shrill screams of a hierophant, to clash ecstatic castanets in his silent alcoves!"
