GREEN MOUNTAINS are a part of the Appalachian sys tem of North America extending from the Massachusetts border northwards through the centre of the State of Vermont to the Canadian line. For two-thirds of the length of the State the range is only slightly broken, forming a water-parting between the streams which flow W. or N.W. into Lake Champlain or the Hudson river and those flowing S.E. into the Connecticut river; but further north the range is cut deep by the valleys of the Winooski and Lamoi11e rivers. The ranges, about 3om. wide in southern Vermont, narrow down to I m. wide at Mount Mans field and broaden again to the north. The crest line is generally more than 2,000f t. ; 32 summits are over 3,000f t. ; and the follow ing peaks exceed 4,000f t.: Mount Mansfield, 4,4o6f t. ; Killington Peak, 4,241 ft.; ; Lincoln, 4,13 5 f t. ; Camel's Hump, 4,o83 f t. ; and Jay Peak, 4,018ft. Smuggler's Notch, just north of Mt. Mans field, is one of Vermont's wonders. Here one finds a rocky wood ed canyon with walls of solid rock on either side rising almost perpendicularly I,000ft. or more; the massive chin of Mt. Mans field towers majestically 3,000ft. above. The entire range, except four of the highest peaks, is heavily wooded with spruce, maple, beech, and birch ; a fact which probably suggested the name. The region is made accessible to tourists by railways, highways, and within the mountains, by the "Long Trail" of the Green Mountain Club which traverses the entire length of the range.
