Agriculture of New York : comprising an account of the classification, composition and distribution of the soils and rocks ... together with a condensed view of the climate and the agricultural productions of the state. Agriculture; Soils; Fruit-culture. 13(5 CHAMPLAIN DIVISION. Another great line of fault exists upon the eastern suit- of the Hudson and Champlain rallies: it in fan has elevated the country in such a manner thai the line of fracture bounds the valley. The mosl conspicuous eminences are near this line, and the rocks are the dates of the Taconic system, surmounted bj one r more varieties f the Calciferorrs sandstone. Qreenbush, Baldmonntain, Granville, Whitehall, Addison, Burlington, Mil- ton, are upon this line of fracture, audi might mention many other intermediate points where all the phenomena I have stated may lie witnessed. The agent which determined the existence and direction of this great longitudinal dis- placement of the strata, gave Origin also to the valliesof the Hudson river and Lake Champlain ; or, it may he more properly said, that the boundaries were first determined by it, and that then the rallies themselves were formed by denudation. The entire series of sedimentary rocks, which have been elevated and thrown into an inclined position, lie between tin- base of the Helderberg and the Hoosic mountains. But in taking so wide an area as this, we undoubtedly embrace fractures more ancient than the one which forms the valley of the Hudson. This, though it disturbs the Hudson-river rocks mostly, yet in one section of country it passes through a prolongation of the Helderberg division ; showing, in this fact, that it was really of a date as late as the Onondaga limestone. But the Taconic rocks were elevated, and made to assume an inclined position, before the deposition of the oldest member of the New-York system : this follows from the unconformahility of the two s\ stems ; but it is impossible to fix upon the era. The Taconic rocks rare
