A boy who is lazy at Greek or Latin would work admirably were he taught in science, especially if taught by the medium of manual labour. A girl reputed nought at mathematics becomes the first mathematician of her class if she by chance meets somebody who can explain to her the elements of arithmetic she did not understand. And a workman, lazy in the workshop, cultivates his garden at dawn, while gazing at the rising sun, and will be at work again at nightfall, when all nature goes to its rest.
