It took but a short time to carry out this delightful plan, and at the opening of my story the children had already been a week at the seashore. Such fun as they had been having bathing, digging in the sand, gathering shells and seaweed, or sitting quietly with grandma under the big umbrella, watching the waves break and roll up on the shore! And after supper there was always that pleasant half hour, on the little balcony overlooking the ocean, when grandma told her bedtime stories. They were all sitting there on this particular evening, grandma in her big rocking-chair, and Bob and Eleanor on their favorite cushions at her feet. The little folks had been begging for their usual treat, for grandma's stories were delightful, and her fund of knowledge (to the children), quite limitless. "I'm getting too old for fairy stories," said Eleanor, who was eleven and had advanced ideas. "Only real _little_ children believe in goblins and giants, and I'm in the third reader now." "I like 'em," said dreamy, nine-year old Bob, "fairies and giants can always do things that just ordinary people can't. Please do tell us some fairy stories, grandma." "No, true stories," insisted Eleanor. "How would it do to make a compromise?" suggested grandma. "You were asking me some questions yesterday about the shells, seaweed and all the fascinating things found on the shore. Suppose I tell you a story about all the wonderful creatures that live in the ocean? The part of it that tells how they live and grow, and get their food will be all true, and I think Eleanor will find it more marvelous than the make-believe part, which will tell about the adventures, and the conversations that our hero had with the strange creatures that he met with in his wanderings." This proposition was agreeable; the children settled themselves comfortably to listen, and grandma, with her eyes on a passing sail, began-- CHAPTER I HOW SAMMY WENT OUT TO SEE THE WORLD Once upon a time there lived in the depths of a deep, tranquil pool a young salmon, whom we will call "Sammy," for short. He was a very handsome fish, and decidedly vain of his good looks. His flesh was a beautiful pink, and the scales that form the armor, or coat-of-mail of most fishes, were particularly handsome on Sammy, and glittered with many colors in the sunlight. He had a very graceful shape besides, and his fins were the envy of all the young fish of his acquaintance. Almost all fishes have a great many fins, and although they differ sometimes in position and number according to the fish, the most important ones are the Dorsal fin, which stands straight up from the back, the Caudal fin, which is in the end of the tail, and the Pectoral fins, which are at the sides and take the place of feet in animals.
