" Outside the city they may be seen carrying huge loads on their heads, as happy as possible, not because they are kindly treated or that their work is light, but because it is their nature to be gay and light-hearted, because they, have conceived neither joys nor hopes which may not be gratified at will, nor cherished any ambition beyond their reach, and therefore have not been baffled in their hopes nor known disappointment. "
