“You’d better stay in after school, William, and I’ll explain.”

William scowled, emitted his monosyllable of scornful disdain “Huh!” and relapsed into gloom.

He brightened, however, on remembering a lizard he had caught on the way to school, and drew it from its hiding-place in his pocket. But the lizard had abandoned the unequal struggle for existence among the stones, top, penknife, bits of putty, and other small objects that inhabited William’s pocket. The housing problem had been too much for it.

William in disgust shrouded the remains in blotting paper, and disposed of it in his neighbour’s ink-pot. The neighbour protested and an enlivening scrimmage ensued.

Finally the lizard was dropped down the neck of an inveterate enemy of William’s in the next row, and was extracted only with the help of obliging friends. Threats of vengeance followed, couched in blood-curdling terms, and written on blotting-paper.

Meanwhile Miss Drew explained Simple Practice to a small but earnest coterie of admirers in the front row. And William, in the back row, whiled away the hours for which his father paid the education authorities a substantial sum.

But his turn was to come.

At the end of afternoon school one by one the class departed, leaving William only nonchalantly chewing an india-rubber and glaring at Miss Drew.

“Now, William.”

Miss Drew was severely patient.
