As twilight deepens and the moon comes up from behind the grim form of the Dome, the mournful notes of a distant chorus of whippoorwills begin, echoing on until far into the early morning. The other noon I was startled to hear a baby whippoorwill practising his melancholy tale on the hillside above the house, where no doubt his mother had lost him the night before. He had “stayed out all night,” and knew no better than to sing in the daytime. I suppose his mother had not yet taught him when and how to sing, for he could only lisp now, saying “’Tis-so-still! ’Tis-so-still!” It sounded very odd at noon, although it was dark and rainy. I searched through the daisied meadow for him, and found that he was a full-sized bird,—too large to be lisping such baby notes, though not old enough to find the way to the twilight woods alone. Perhaps he was backward in his singing lessons, and his mother had punished him by leaving him to practise all day, when other birds of the night were drowsing under the shelter of old logs in the deep wood. So he sang on and on, at intervals, all the afternoon in the rain, out on the grassy hilltop. I found a bobolink’s nest low in the swamp meadow, near where there were many busy “Roberts of Lincoln.” Their rich, energetic, gladsome song was very contagious, and brightened many an hour when I was housed, or sat on the porch, watching the storms come up in the north and west. [Illustration: =The Perry Elm, Marking the Site of Fort Massachusetts, on the Harrison’s Flats, North Adams, Massachusetts, Showing Saddleback Mountain in the Distance.=] Mount Œta is one of the foothills of the Dome, lying just west of the Domelet. The Hoosac glides around its “dug-away” base, passing through the narrowest portion of the valley near the Massachusetts State Line. This pass is often called the “Golden Gate,” likened to the Pass of Thermopylæ, among the mountains of ancient Greece. Indeed, the warring history of this valley may be comparable with that of the plains of Marathon and the mountains of Hellas. Through the Hoosac Pass, during the French and Indian Wars, have marched the French cadets and cunning Indians, led by General Rigaud de Vaudreuil, to storm and capture Fort Massachusetts near the base of Greylock’s Brotherhood. Here they fought, sixty to one. These encounters were but forerunners of the Bennington rebellion among the Green Mountain Boys, and the conflicts at Ticonderoga, which led to one of the world’s great battles, fought among the hills and vales of Saratoga. The summit of Mount Œta is crowned with luxuriant farms, with flowing fields of grain and grasses. Miniature hills and vales between, with little streams leading down the slopes, perfect an ideal pastoral dream. There is none of the boldness in the scene from this height, as observed from Mount Greylock, Mount Anthony, or the Majestic Dome.
