[Sidenote: _A PANIC ON THE MARSH._] Now that the nest was deserted and the young were always going about with their mother, I wondered that the head of the family did not relax his vigilance over the meadow and abandon his two watch-towers; but save that his enticing song came up to me oftener than his cries of distress, his habits were not materially altered. One day, when I thought his summer troubles ought surely to be over, a fresh anxiety came to him. Several women and girls, with a dog, appeared on the marsh, which at low tide was in some parts explorable. The human members of the party amused themselves with bathing and wading in the now shallow stream; but the dog acted like one gone mad, dashing about on those peaceful flats where so many birds were enjoying themselves quietly, rushing full gallop from one group to another, wading or swimming the winding stream every time he came to it, and barking at the top of his voice every instant. Birds rose before him in flocks, sandpipers took to their wings in panic, swallows swooped down over him in anxious clouds, sharp-tailed sparrows and all other winged creatures fled wildly before this "agitator," who seemed to have no aim except to disturb, and reminded me irresistibly of his human prototype. Somewhere in that "league upon league of marsh grass," I suppose, were the blackbird's little folk; for the watcher on the bank was in deepest tribulation, and his outcries quickly brought me down to see what had happened. The Young Americans of the redwing family are as vivacious and uneasy as might be expected of the scions of that house. No sooner do they get the use of their sturdy legs than they scramble out of the nest and start upon their bustling pilgrimage through life, first climbing over the bushes in their neighborhood, and as they learn the use of their wings becoming more venturesome, till at last, every time a hard-working mother brings a morsel of food, she has to hunt up her straggling offspring before she can dispose of it. Though eager for food as most youngsters, they are altogether too busy investigating this new and interesting world to stay two minutes in one place. So far from waiting, like Mr. Micawber, for something to turn up, they proceed, the moment they can use their limbs, to attack the problem of delay for themselves; to wait is not a blackbird possibility. It is needless to say that such preternaturally sharp and wide-awake Young Americans very soon graduate from the nursery. [Sidenote: _A YELLOW-HEADED MONSTER._]
