"Have you seen the little piggies crawling in the dirt?"

There is something very soothing and comforting about a scene of livestock domesticity: lambs lying in twos beneath the shade of a clump of trees; a small herd of brown cows, lazily swishing their tails in a gently rolling field full of buttercups; a dozen piglets gamboling excitedly round a stolid sow. And though every year the individual animals of such scenes may change, yet every year these tableaux are repeated. They are like cloud-scapes - ever changing, yet ever the same, renewing themselves and repeating themselves, over and over again.
