"Of course-of course," said the Doctor. "I'll get you some at once." "I would like a pair like yours," said the horse-"only green. They'll keep the sun out of my eyes while I'm plowing the Fifty-Acre Field." "Certainly," said the Doctor. "Green ones you shall have." "You know, the trouble is, Sir," said the plow-horse as the Doctor opened the front door to let him out-"the trouble is that anybody thinks he can doctor animals-just because the animals don't complain. As a matter of fact it takes a much cleverer man to be a really good animal-doctor than it does to be a good people's doctor. My farmer's boy thinks he knows all about horses. I wish you could see him-his face is so fat he looks as though he had no eyes-and he has got as much brain as a potato-bug. He tried to put a mustard-plaster on me last week." "Where did he put it?" asked the Doctor. "Oh, he didn't put it anywhere-on me," said the horse. "He only tried to. I kicked him into the duck-pond."
