I obey the first clause of the injunction by trying once more, but am not so successful with the second, for I am very stupid. I tumble down before I get to the old place, at a point where I was all right before, and stop to think. But I can’t think about the lesson. I think of the number of yards of net in Miss Murdstone’s cap, or of the price of Mr. Murdstone’s dressing-gown, or any such ridiculous problem that I have no business with, and don’t want to have anything at all to do with. Mr. Murdstone makes a movement of impatience which I have been expecting for a long time. Miss Murdstone does the same. My mother glances submissively at them, shuts the book, and lays it by as an arrear to be worked out when my other tasks are done.
