"Eh, I can't run any more. I've got a bone in my leg."
"And haven't I?" asked Archie.
"No, dear: you're just made of gristle and quicksilver," said Blessington, with a sudden lyrical spasm as she looked at the shining face of her most beloved.
"What's quicksilver?" asked Archie. "And why haven't I got a bone in my leg? O-o-oh!" and a sudden thought struck him. "Have women got bones in their legs and not boys? Is that why they can't run properly? Mummy can't run, nor can you; but William can, damn him."
"Master Archie!" said Blessington in her most severe voice.
"What for?" asked Archie.
"You must never say that, Master Archie," said Blessington, who only called him Master Archie on impressive occasions. "You must never say what you said after 'William can.'"
"But daddy said it to William this morning," said Archie.
Blessington still wore the iron mask on her face. It was lucky for her that Archie did not know how puzzled she was as to the correct answer.
"Your papa says what he thinks fit," she said, "and that is right for him. But young gentlemen never say it."
