Of course you have all heard of the wonderful flying machines which are now being made. To fly at all, you must be able to do three things: lift yourself up, keep yourself up, and move about. If you can do these three things just as quickly and just as slowly as you want to, you will be able to fly perfectly. The hardest puzzle of all is how to make a machine which will keep itself up (and the right way up too) without moving about very quickly. This is what many birds can do so beautifully, and I expect that in time (all great inventions take a long time to make perfect, and they are never the work of one man alone, but rather of one man helped by the work of many men who lived before him) machines will be made in which men will be able to fly as perfectly as birds. At present they only fly as perfectly as beetles, but that they should be able to do this is a very wonderful thing. The great difference, in flying, between a beetle and a bird like a gull, is that the beetle has to keep going full speed all the time, or else he will tumble down to the ground, while a bird like a gull can poise balanced in the air, with just a flap or turn of his wings now and then to keep himself the right way up.

The "go-to-bury" rabbits have the longest ears, but the "stub" rabbits, as any stoat will tell you, are the best for dinner. Moreover, there are rabbits and bunny rabbits--but all were bunny rabbits once. [Illustration] Bunny Rabbit missed the bluebells, though these rang in his birth. Up rose the kingly foxgloves, tier upon tier of them pink-purple, but Bunny Rabbit missed these too. A golden world--the ragwort blazing on the slope, below the mellowing corn-field, and, mantling primrose hills, the dawn. Now Bunny Rabbit was ready. The burrow winds in four sharp turns, and, at each one, he stubbed his nose. This through a mad desire to keep near Mother; for Mother's tail bobbed in quick jerks, shaving each corner to a hair, and he and all his brothers raced to catch it. They reached the entrance packed as one, but Bunny Rabbit, squirming clear, shot past the uplifted paw, butted his waiting Father, flung off him like a smoke-puff, and landed on his back six feet below. That is why he has a separate history. It was indeed sharp change of circumstance. The nursery had been pitch-black, though one short gleam of light had reached it daily. That was when Mother Rabbit snatched her food, and sealed the entrance up for fear of Father. At other times she screened her babies' eyes. So now the sunshine blinded Bunny Rabbit, and pointed grass-stems pricked a skin which nothing harder than breast-fur had touched. [Illustration: AND LANDED ON HIS BACK SIX FEET BELOW]
