They threaded their way through the crowds of folks on the sand to the spot where Mrs. Humphrey thought the cleanest, nicest sand was found, and there—just as though he had been there all afternoon—was Uncle Hal and three of his friends! "I thought you were going to pack!" exclaimed Mrs. Merrill in amazement. "So I was," laughed Hal, "but why pack when I could go in swimming?" "But how did you happen to come here?" asked Alice. "I didn’t ’happen,’" Hal assured her. "Art came over and said you were coming down here, and as it turned off so hot, wouldn’t I like a swim, and I would—so here we are. Want some good company?" "’Deed we do!" Mary Jane assured him, and much relieved, Mrs. Merrill and Mrs. Humphrey sat down on the rugs to continue their visit while the two girls, with the four college men for escorts, raced down into the water. Mary Jane supposed she would have had fun on the beach, wading by the edge of the big waves even if Uncle Hal had not come. But it wouldn’t have been fun such as she and Alice had with him there. The great waves rolled in and broke in a crest of foam near the shore and then spread in a frill of bubbles over the golden sand. Uncle Hal picked her up in his arms and walked with her way out into the water; then, holding her high, let her feel the "break" of the waves close to her face. She shouted with glee and splashed her hands in the crest of foam—never had she had such fun! Then, taking her out deeper, where the waves did not break but rolled along in a great swell, he held her tightly by her bathing suit and under her chin and let her swim. It was fun to feel the water rolling, to let herself go as Uncle Hal told her to, and to breathe slowly and comfortably and work her hands and feet, feeling all the while the security of her uncle’s strong arm. "Let’s do it some more!" she cried, as he took her in to shore. "Pretty soon," he replied, "but you stay on the sand awhile now with Alice while I swim out to the raft to warm up. Then you shall have another swim—two, if you want them." Back on the sand with Alice, Mary Jane found it nearly as much fun to dig and hunt shells as it was to swim. There seemed to be no pretty shells as there were on the beaches in Florida; perhaps because the crowds of people kept them picked over; perhaps because up further north there were not such pretty shells to be washed up. But there were plenty to build a wall with even if all were not beautiful and perfect. She and Alice collected several handfuls and then set about building a city with a wall around it. Other children playing near saw the plan and helped too, and in a few minutes a dozen little folks were working under Alice’s direction, building streets, parks, houses, churches and the outer wall. It was great fun and as they worked the time sped by, one hour, two, and the girls would have guessed it wasn’t more than ten minutes.
