"May I offer an apology for hitting Helen with my boomerang?"

"Do," my mother replied. "It is exceedingly unusual for a Jevons to be aware he owes one."

The ducklings arrived at this point, and I arose to get a firmer grip upon them than was possible from a chair. Delicately I made the first incision, only to discover that ducklings do not respond to delicate treatment. I worked in silence for a time upon number one. Although division into his integral factors accumulated many apparent units, there seemed surprisingly little of him to serve when thus reduced to his lowest terms. Frances giggled.

"You look so funny, Ted," she explained, with sisterly devotion.

"For that you shall have a drum-stick," I retorted.

"I can see nothing funny in watching good food being ruined," my mother said encouragingly. The housemaid standing at my elbow with a plate ready made me nervous.

"It is a curious fact," my mother went on, in a reminiscent mood, "that no Jevons could ever carve. They are the most incompetent men that ever existed."

As I knew for a certainty that the only two Jevonses on earth my mother had ever seen were my father and myself, I wondered whether she was drawing on state documents or simply making a sweeping generalization from two examples. Something told me, however, not to argue this point.

"A duckling," I said, "is an act of God. Steamer tickets and insurance policies specially provide for no liability for such. Even a Jevons is powerless in the face of the handiwork of Providence."

"Sit down, Ted, and let me finish. It makes me ill to see you messing up those ducklings," my mother said. Willingly I changed places. To my secret joy she splashed some gravy on the table cloth. I tried to kick Helen under the table, but all I did was to make an awful crash against one of the complicated gate legs. My mother looked fixedly at me. I did not move a muscle of my face.
