"There you are," the boy said to Sunny, as he set him carefully down. "Now you take my advice and trot along home and get on dry shoes and stockings. You'll be sneezing your head off to-morrow, if you don't look out." "But I want my grandpa!" said Sunny Boy, beginning to cry. "I lost my grandpa! Maybe he is all drowned!" No wonder Sunny Boy cried at this sad thought. He loved his Grandpa Horton very dearly and he was named for him, "Arthur Bradford Horton." To be sure, no one ever called the little lad by that long name, for "Sunny Boy" seemed to suit him so exactly. But, of course, when he grew up and was a farmer or a traffic policeman or the captain of a sailboat--he didn't know yet which he would rather be--he would need his real name. Perhaps you know all about Sunny Boy. If so, we do not have to introduce you. But if you have not read the other books about him you will want to know that he lived with his daddy and his mother and Harriet, who had helped his mother since Sunny Boy was a tiny baby, in the city of Centronia and that Grandpa and Grandma Horton lived on a beautiful farm, "Brookside," where Sunny Boy and his mother had spent a month the summer before. The first Sunny Boy book, called "Sunny Boy in the Country," tells all about this visit and the friends Sunny Boy made there and about the kite he made which got him into trouble. But that ended happily and Sunny Boy was so happy at Brookside that he might have decided to be a farmer if he and his daddy and mother had not gone to the seashore to visit his Aunt Bessie. "Sunny Boy at the Seashore" tells about the fun a small boy can find in the sand and of Sunny Boy's experiences in sailing boats, and especially about the time he drifted out to sea in a rowboat all by himself. His mother and daddy, in another boat, found him, though, and Sunny Boy thought he would like to be a sea captain like the kind Captain Franklin who ran the motor-boat which caught up with him just as he was beginning to be very much afraid he was lost. Sunny Boy knew that he could not be a sea captain before he was grown up, and long before that, the very next month, in fact, Daddy and Mother Horton took him to New York City, and, dear me, didn't he find adventures there! He was lost twice and he took his mother shopping and he visited Central Park and the Statue of Liberty and he saw so many things that he kept remembering them long after he was home again. "Sunny Boy in the Big City" is the title of this third book, and the traffic policemen interested him so much that he thought he would put off being a sea captain till he had tried to be a policeman.
