"... the Kiwi (Apteryx) ... runs rapidly, but has no power of flight. Its body is covered with a thick coating of almost hair-like feathers. By feeling with the finger amongst these feathers one can detect the presence of a miniature wing hidden amongst them. It is so small as to be absolutely useless, although it is asserted that the kiwi tries its best to tuck its bill under it when it goes to sleep!"
