Peter tried to believe that what Jenny Wren had told him was nothing but a story, but do what he would, he couldn't rid himself of a little doubt. He tried to interest himself in the affairs of the other little people of Old Orchard, but it was useless. That little doubt kept growing and growing. Could it be possible that Jenny Wren had spoken the truth? Could it be that he really didn't know what relatives he had or anything about them? Of course Old Mother Nature could tell him all he wanted to know. And he knew that whatever she might tell him would be true. Finally that growing doubt, together with the curiosity which has led poor Peter to do so many queer things, proved too much for him and he started for the Green Forest to look for Old Mother Nature. It didn't take long to find her. She was very busy, for there is no time in all the year when Old Mother Nature has quite so much to do as in the spring. “If you please, Old Mother Nature,” said Peter timidly but very politely, “I've some questions I want to ask you.” Old Mother Nature's eyes twinkled in a kindly way. “All right, Peter,” she replied. “I guess I can talk and work at the same time. What is it you want to know?” “I want to know if it is true that there are any other members of the Rabbit and the Hare family besides my big cousin, Jumper, who lives here in the Green Forest, and myself.” Old Mother Nature's eyes twinkled more than ever. “Why, of course, Peter,” she replied. “There are several other members. You ought to know that. But then, I suppose you don't because you never have traveled. It is surprising how little some folks know about the very things they ought to know most about.” Peter looked very humble and as if he felt a little bit foolish. “Is--is--is it true that way down in the Sunny South I have a cousin who loves to spend his time in the water?” stammered Peter. “It certainly is, Peter,” replied Old Mother Nature. “He is called the Marsh Rabbit, and he is more nearly your size, and looks more like you, than any of your other cousins.” Peter gulped as if he were swallowing something that went down hard. “That is what Jenny Wren said, but I didn't believe her,” replied Peter meekly. “She said she had often watched him swimming about like Jerry Muskrat.” Old Mother Nature nodded. “Quite true. Quite true,” said she. “He is quite as much at home in the water as on land, if anything a little more so. He is one member the family who takes to the water, and he certainly does love it. Is there anything else you want to know, Peter?” Peter shifted about uneasily and hesitated. “What is it, Peter?” asked Old Mother Nature kindly. “There is nothing in the Great World equal to knowledge, and if I can add to your store of it I will be very glad to.” Peter took heart. “If--if you please, Mother Nature, I would like to learn all about my family. May come to school to you every day?”
