I could see Arthur's lips moving. He certainly was trying very hard. But soon he took his eyes off the book; his lips stopped moving. His look wandered everywhere, but not back to his book. Suddenly he caught my eye; I made a sign to him to go on with his lesson. He smiled, as though to thank me for reminding him, and again fixed his eyes on his book. But as before, he could not concentrate his thoughts; his eyes began to rove from first one side of the canal to the other. Just then a bird flew over the boat, swiftly as an arrow. Arthur raised his head to follow its flight. When it had passed he looked at me.
"I can't learn this," he said, "and yet I want to."
I went over to him.
"It is not very difficult," I said.
"Yes, it is, it's awfully difficult."
"It seems to me quite easy. I was listening while your mother read it, and I almost learned it myself."
He smiled as though he did not believe it.
"Do you want me to say it to you?"
"You can't."
"Shall I try? You take the book."
He took up the book again, and I began to recite the verse. I had it almost perfect.
"What! you know it?"
"Not quite, but next time I could say it without a mistake, I believe."
"How did you learn it?"
