"Suppose, Norah, you tell us all you know about the cow.""Very well," said Norah, "I"ll begin by saying that the cow is a large thickset animal, with short, stout, strong legs, just fit to support so heavy a body. It has a thick skin, which we call a hide, and the hide is covered with close smooth hair. It has a pair of smooth, pointed horns, and large broad ears, and its eyes are large and gentle looking.""Now I think that"s very good for a little girl," said Willie. "Suppose we begin, Fred.""All right," said Fred, "we"ll have a look at the feet. The cow"s foot is just like the sheep"s foot. It has four toes,but it walks only on the two front ones. The two short toes behind never touch the ground.
