West of the Green Mountains the Taconic Mountains form a nearly parallel (but distinct) range, extending from New York and Massachusetts N.
The Taconic Mountains rise in very irregular masses to1500-2000ft., and reach their maximum elevation in Mount Equinox at 3816 ft.
In it are the Scoville Memorial Library (about 8000 volumes in 1910); the Hotchkiss preparatory school (opened in 1892, for boys); the Salisbury School (Protestant Episcopal, for boys), removed to Salisbury from Staten Island in 1901 and formerly St Austin's school; the Taconic School (1896, for girls); and the Connecticut School for Imbeciles (established as a private institution in 1858).
High), separating the valleys of the Housatonic and Connecticut, are a range of the Berkshires, a part of the Appalachian system, and a continuation of the Green Mountains, of Vermont, and with the Taconic range on the west side of the Housatonic Valley - of which the highest peaks are Greylock, or " Saddleback " (3535 ft.), and Mt Williams (3040 ft.) - in the extreme north-west corner of the state, form the only considerable elevated land.'
Jules Marcou and others have used Taconic (Taconian) as the equivalent of Cambrian, and C.Lapworth proposed to apply the same term to the lowest sub-division only; he had also used "Annelidian" in the same sense.
