All that livelong day, a day no one of them ever forgot, they spent by the river side, dabbling their little dark-green legs in the water when an eddy sent it gently up to them, learning to find the sweetest and wholesomest insects lurking among the pebbles, with now and then a little worm, or caterpillar that had fallen from the bushes above: watching the trout turning up their golden sides in the dark water of the pool as they rose to the flies: practising their voices in a feeble piping, and always moving bodies and tails as they saw their parents do it. They had very few alarms, but quite enough for practice in hiding. Once as they were following their mother by the very edge of the deep pool, a huge silver creature, flashing in the sunlight, leapt clean out of the water and fell in again with a splash. The little ones all dropped to ground and lay silent, but their mother never uttered a note, and they soon got up again. She told them it was only a salmon, who could not possibly do them any harm, and would not if he could; that she and their father were good friends with the salmon, and often sat on the big boulder under which he loved to lie; but that it was only a bowing acquaintance, because the salmon could not talk their language. Once or twice an angler came along slowly, and then they had to drop while their parents flew up and down stream loudly calling; but there was always plenty of time for them to get into holes and corners safely, and the anglers passed on again without noticing either young or old. At last the light began to fade, the young ones were tired and sleepy—even the eldest, who had distinguished himself by trying to fly, and actually getting out on a stone half a foot from the shore, where he stood bowing with great pride till his father came and shoved him into the water to scramble ashore in a fright—and so this delightful day came to an end, and they all went back to the shelter where the nest was placed. The next day was a Sunday, and they spent half the morning in great happiness without seeing a single fisherman. But after all they were to learn this day that life has its troubles: for a huge heron took it into his head to fish while human beings could not, and alighted at the water’s edge within a dozen yards of the spot where they were already motionless in obedience to their mother’s signal pipe. And there the great bird kept standing on one leg for a full hour, and would not move a muscle, except when now and then he darted his long bill into the water, and then heaved it up into the air with a trout struggling at the end of it. At last, as his back was turned to them, their parents whistled them away, and they crept back to the nest in deep disappointment. “Why should we be afraid of that creature?” asked the eldest: “he eats fish, not Sandpipers.”
