"You are right in one sense, my boy, but the word citizen has also a far wider meaning. Do you know what it is, Olive?" But Olive was not sure, and the Doctor asked her to go to his study and look for the word in the big dictionary.

In a few minutes she returned with a slip of paper from which her father read: "Citizen—a member of a nation, especially of a republic; one who owes allegiance to a government and is entitled to protection from it."

"Now, if you listen carefully I think I can prove to you that every bird you can find is such a citizen of this country, and show you why we should protect him.

"I told you the other day how the body of a bird was planned and built to fill a place no other animal could take. Thus by his habits and character every bird fills a place as a citizen of our Republic, keeping the laws and doing work for the land that House People, with all their wisdom, cannot do. Every such fellow-animal of ours, besides having eyes to see with, and a brain which, if it does not tell him as many things as our brains tell us, yet teaches him all that he need know to follow the laws that Heart of Nature has set for him, has the same feelings and affections as ourselves. Parent birds love each other and their little ones, and often lose their lives in trying to protect them. They build their homes with as much care and skill as House People use in making theirs. Then they work hard, very hard indeed, to collect food to feed their children, for bird children are, oh, so hungry! They grow very quickly, and must eat constantly from morning until night.

"With them it is breakfast, luncheon, dinner, five-o'clock tea, and supper, with a great many other meals between times that would not be wholesome for House Children. So you can see for yourselves that we may well call the bird a fellow-being."

"Yes," said Rap, his eyes beaming as if he had something to tell, "some birds work as hard as mother does. I watched a pair of Robins all one day last spring, when I was sick. They had a nest in a bush by our kitchen window, where I could see it well, and all day long either the mother or the father came about every two minutes with something for the little ones to eat. I timed them by the clock until I was nearly dizzy, and they seemed to do the same thing every day until the young ones flew away. Then they went over to the grape vines, made a new nest, and raised four more the same way"—and then Rap stopped suddenly, as if he feared that he had been talking too much.

"That is all true," said the Doctor, looking very happy at finding that one of his listeners not only saw for himself but remembered and thought about what he had seen. "If you have used your eyes so well, my lad, when we come to the bird stories I shall expect you to tell some of them yourself." And the Doctor held out his hand to the child with a look that sent him to bed to dream happy dreams for many a night.

The children gazed at Rap in surprise. It was a new idea that a poor little fellow like him should know more than they, who had both parents and nice clothes, and had been to school in a big city. That he should be able to tell stories about birds seemed wonderful. But they were not selfish, and instead of being jealous felt a great respect for Rap.

"Now," said the Doctor, "we will see what a good neighbor to House People a bird is, and how in working for himself he helps them also."

"How can birds possibly work to help people?" asked Dodo and Nat together; but Rap smiled to himself as if he knew something about the matter, and said, "They eat the bugs and worms and things that kill the gardens and fields."
