It is probable that ordinarily, when the mother bird left the nest, she would arrange the leaves so as entirely to cover the hole beneath. If this were done, it would seem impossible that they concealed anything, for they would be apparently flat on the surface of the ground. My unexpected approach had flushed her before she had time to put back the leaves.

The pleasure of finding such a skilfully concealed nest is indescribable. The hunt is a contest between intelligence and instinct, where victory by no means always inclines to the human. As I looked down at the nest, I knew just how the talented recluse in “The Gold Bug” felt when, after solving the cryptogram and disposing of every difficulty, he at last gazed into the open treasure-chest.

To-day there was to be no such glorious experience, and we finally gave up the hunt and started back across the meadow. As we moved through the swishing grass, suddenly we heard a curious clicking bird-note. “See-lick, see-lick, see-lick,” it sounded, and we recognized the unfamiliar notes of that rare little black-striped sparrow, the Henslow. The last time we four had heard that note together was on a trip into the heart of the pine-barrens, when we not only identified this bird for the first time, but also found its nest, a treasure-trove indeed. To-day we did not even get a glimpse of the bird.

Beyond the meadows we came face to face with the marsh itself, and plunged in to show the Banker and the Architect our marsh hawk’s nest. On the way back the Artist made a discovery. Waist-deep among the sedges, with the tiny marsh wrens chipping and bubbling all around him, he suddenly espied a round ball made of green grass fastened to the rushes with a little hole in one side.

“The nest of the short-billed marsh wren!” he declared loudly. We hurried to him. The nest was empty, but, as it was early for the wrens to be laying, this fact had no effect on his triumph. We admired the nest, the bird, and the discoverer freely—all except the Architect, who lingered behind the rest of us, regarding the nest with much suspicion. Suddenly he noted a movement in the grass, and as he watched, a tawny little meadow mouse climbed up the grass-stems and popped into the hole in the side, to find out what this inquisitive race of giants had been doing to his house. It was pitiful to see the Artist. At first he denied the mouse. Then, when it dashed out in front of us, he claimed that its presence had nothing to do with the question of the ownership of the nest.

“Isn’t it possible,” he demanded bitterly, “that a well-behaved meadow mouse may make a neighborly call on a marsh wren?”

“No,” replied the Architect decisively; and we started away from the discredited nest.

Later on, the Artist had his revenge. We were hunting everywhere for the bittern’s nest. Suddenly, as the Artist stepped on a tussock, a large squawking bird flew out from under his foot. No wonder she squawked. He had stepped so nearly on top of her that, as she escaped, she left behind a handful of long, beautifully mottled tail-feathers, unmistakably those of an English pheasant. The nest was at the side of the tussock, entirely covered over with the arched reeds, and contained fifteen eggs, three of which the clumsy foot of the Artist had broken. They were of a chocolate color and, curiously enough, almost identical in color and size with those of the American bittern, except that the inside of the shell of the broken eggs was a light blue. The nest itself was nearly eight inches across and about three inches deep, made entirely of grass. Hurriedly clearing away the broken eggs, we called the Architect from the far side of the marsh. He hastened up, took one look at the nest, and then told us solemnly that this was one of the most unusual occurrences known in ornithology. Three pairs of bitterns had joined housekeeping and laid eggs in the same nest. It was hard on the Architect that we should have flushed probably the only bird in the world whose eggs are almost identical in color and size with those of the American bittern, and it was not until the Artist produced the pheasant’s tail-feathers that our friend would admit that there was anything wrong with his theory.

As we started to leave the place, I saw on the other side of the tussock the largest wood-turtle I have ever met. Its legs and tail were of a bright brick-red, while the shell was beautifully carved in deep intaglios of dingy black and yellow. This turtle ranks next to the terrapin in taste, a fact which I proved the next day. As Mr. Wood-Turtle is fond of bird’s eggs, I strongly suspect that my capture of him was all that saved the lives of a round dozen of prospective pheasants. We had a leisurely lunch near one of the coldest bubbling springs in the world, seated on a high, dry ridge under the shade of a vast black-walnut tree. After lunch we crossed quaking, treacherous bogs, that lapped at our feet as we passed, and reached Wolf Island. It was made up of a series of rocky ridges, shaded with trees and masked by a dense undergrowth. Beneath the great boulders and at the base of tiny cliffs, we could trace dark holes and burrows where two centuries ago the celebrated pack made their home.

Beyond the Island a tawny bird slipped out of a tussock ahead of me, like a shadow. Hurrying to the place, I found the perfectly rounded nest of a veery thrush, lined with leaves and entirely arched over by the long marsh-grass. From the brown leaf-bed the four vivid blue eggs gleamed out of the green grass like turquoises set in malachite. The eggs of a catbird are of a deeper blue, and those of a hermit thrush of a purer tone, but of all the blue eggs, of robin, wood thrush, hermit thrush, bluebird, cuckoo, or catbird, there is none so vivid in its coloring as that of the veery. That nest with its beautiful setting stands out in my mind as a notable addition to my collection of out-of-door memories.
