Zeke found the entrance to the weir and they followed him in. Here the water was waist-deep. Zeke explained the plan of the weir. It was, he pointed out, nothing but a deep-sea trap for fish. The fish entered through the narrow opening into a channel which led into the big inner maze. Although it was very easy for them to float in, it was a very difficult matter finding the way out. Caught there, as the tide retreated, they stayed until the fisherman arrived with his cart and shoveled them ignominiously into it. “Oh, oh!” Laura shrieked suddenly. “This place is full of fish. One just passed me! Oh, there’s another! And another!” But by this time both the other girls were jumping and screaming with their excitement; for fish were darting about them everywhere. The boys, not at all nervous of course and very much excited, were trying to drive the fish into corners to find out what they were. Zeke identified them all easily enough--cod, sculpins, flounders, and perch. “What’s that big thing?” Arthur exclaimed suddenly. “Jiminy _crickets_!” he called excitedly. “It’s the biggest turtle I ever laid my eyes on.” The girls shrieked and stayed exactly where they were, clinging together. But the males all ran in Arthur’s direction. “Dat’s some turtle, believe muh,” commented Zeke. “I’m going to take it home,” Arthur declared, “and put it in the Magic Mirror.” “The Magic Mirror!” Laura echoed. “Why I would never dare go in swimming if I knew that huge thing was there.” “We’ll keep it tied up with a rope,” Arthur went on excitedly. “It can’t get where we go in swimming because the rope won’t be long enough. Come on, fellows, help me get it.” “How are you going to catch it?” Harold demanded. “Lasso it!” Arthur declared, untying a stout rope which hung from one end of the weir posts. The prospect of catching such big game was too tempting for the males of the party. And so while the girls dashed madly about, trying to get out of their reach, screaming with excitement and holding on to each other for protection, but really enjoying the situation very much--the boys chased the turtle from corner to corner, until finally Arthur managed to lasso a leathery paw and tie it captive to a weir post. How he did this, he himself found it hard to say, because the water was lashed to a miniature fury by the flounderings of both the turtle and its captors. It was probably pure accident, he was humble enough to assert. But having caught the creature, they were not content until they had brought him ashore, and so the procession started beachwards, Arthur pulling the turtle at the end of the rope. It was a huge turtle at least two feet in diameter. It had wide leathery flappers, a wicked looking head--as big, Rosie said, as her alarm clock. But its shell was beautifully marked.
