ONCE upon a time, many years agowhen our grandfathers were little childrenthere was a doctor; and his name was DolittleJohn Dolittle, M.D. M.D. means that he was a proper doctor and knew a whole lot. He lived in a little town called, Puddleby-on-the-Marsh. All the folks, young and old, knew him well by sight. And whenever he walked down the street in his high hat everyone would say, There goes the Doctor!Hes a clever man. And the dogs and the children would all run up and follow behind him; and even the crows that lived in the church-tower would caw and nod their heads. The house he lived in, on the edge of the town, was quite small; but his garden was very large and had a wide lawn and stone seats and weeping-willows hanging over. His sister, Sarah Dolittle, was housekeeper for him; but the Doctor looked after the garden himself. He was very fond of animals and kept many kinds of pets. Besides the gold-fish in the pond at the bottom of his garden, he had rabbits in the pantry, white mice in his piano, a squirrel in the linen closet and a hedgehog in the cellar. He had a cow with a calf too, and an old lame horsetwenty-five years of ageand chickens, and pigeons, and two lambs, and many other animals. But his favorite pets were Dab-Dab the duck, Jip the dog, Gub-Gub the baby pig, Polynesia the parrot, and the owl Too-Too. His sister used to grumble about all these animals and said they made the house untidy. And one day when an old lady with rheumatism came to see the Doctor, she sat on the hedgehog who was sleeping on the sofa and never came to see him any more, but drove every Saturday all the way to Oxenthorpe, another town ten miles off, to see a different doctor.
