flying with them to the scene of her labors.  She appeared very eager and hasty in her pursuits, and collected her materials without fear or restraint, while three men were working in the neighboring walks, and many persons visiting the garden.  Her courage and perseverance were indeed truly admirable.  If watched too narrowly, she saluted with her usual scolding, tshrr, tshrr, tshrr, seeing no reason, probably, why she should be interrupted in her indispensable occupation.

“Though the males were now comparatively silent on the arrival of their busy mates, I could not help observing this female and a second, continually vociferating apparently in strife.  At last she was observed to attack this second female very fiercely, who slyly intruded herself at times into the same tree where she was building.  These contests were angry and often repeated.  To account for this animosity, I now recollected that two fine males had been killed in our vicinity; and I therefore concluded the intruder to be left without a mate; yet she had gained the affections of the consort of the busy female, and thus the cause of their jealous quarrel became apparent.  Having obtained the confidence of her faithless paramour, the second female began preparing to weave a nest in an adjoining elm, by tying together certain pendent twigs as a foundation.  The male now associated chiefly with the intruder, whom he even assisted in her labor, yet did not wholly forget his first partner, who called on him one evening in a low, affectionate tone, which was answered in the same strain.  While they were thus engaged in friendly whispers, suddenly appeared the rival, and a violent rencontre ensued, so that one of the females appeared to be greatly agitated, and fluttered with spreading wings as if considerably hurt.  The male, though prudently neutral in the contest, showed his culpable partiality by flying off with his paramour, and for the rest of the evening left the tree to his pugnacious consort.  Cares of another kind, more imperious and tender, at length reconciled, or at least terminated, these disputes with the jealous females; and by the aid of the neighboring bachelors, who are never wanting among these and other birds, peace was at length completely restored, by the restitution of the quiet and happy condition of monogamy.”

Let me not forget to mention the nest under the mountain ledge, the nest of the common pewee, a modest mossy structure, with four pearl-white eggs, looking out upon some wild scene and overhung by beetling crags.  After all has been said about the elaborate, high-hung structures, few nests, perhaps, awaken more pleasant emotions in the mind of the beholder than this of the pewee,—­the gray, silent rocks, with caverns and dens where the fox and the wolf lurk, and just out of their reach, in a little niche, as if it grew there, the mossy tenement!
