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).
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.
