premise: It was for Hooty that they took turns in watching .<br>It was just the hour when Hooty likes best to hunt .<br>By and by they heard Booty 's hunting call .<br>It was far away in the Green Forest , Then Mr. and Mrs. Quack felt easier , and they talked in low , contented voices .<br>They felt that for a while at least there was nothing to fear .<br>Suddenly a little splash out in the Big River caught Mr. Quack 's quick ear .<br>As Mrs. Quack brought her head up out of the water , Mr. Quack warned her to keep quiet .<br>Noiselessly they swam among the brown stalks until they could see out across the Big River .
