together again so easily! One lives and one learns, you know!"
"But it needn't be the same one, need it?" said Bruno. "Wo'n't it do, if I live, and if Sylvie learns?"
"I c'an't learn without living!" said Sylvie.
"But I can live without learning!" Bruno retorted. "Oo just try me!"
"What I meant, was" the Professor began, looking much puzzled, "wasthat you don't know everything, you know."
"But I do know everything I know!" persisted the little fellow. "I know ever so many things! Everything, 'cept the things I don't know. And Sylvie knows all the rest."
The Professor sighed, and gave it up. "Do you know what a Boojum is?"
"I know!" cried Bruno. "It's the thing what wrenches people out of their boots!"
"He means 'bootjack,'" Sylvie explained in a whisper.
"You ca'n't wrench people out of boots," the Professor mildly observed.
Bruno laughed saucily. "Oo can, though! Unless they're welly tight in."
