One of these intersects the village and crosses the New York Central railroad at the high stone wall built up from the river at the lower end of the village. The same fault crosses the West Shore railroad just above the deep cut through the Labra^dorite, and this point is also occupied by an extensive filling and stone wall built up from the river level.* The second iault forms the eastern termination of the escarp- ment of gneiss and Calciferous below the village and is a mono- clinal. Another monoclinal fault crosses the valley of the Mohawk river above the mouth of East Canada creek and brings up the Trenton limestone dipping to the west. An anticlinal fault occurs just above Fort Plain. The Calcif- erous dips to the west, and across the line at Fort Plain the Birds- eye limestone is found dipping to the southeast. Just below the bridge at the last-mentioned locality is an exposure of Birdseye limestone, which preserves the remains of former pot-holes at a level of ten feet above the river, showing that at one time there was a natural dam and fall at this point. From Fort Plain to the " Little Nose " the strata lie in a broad synclinal with Canajoharie situated nearly in the center. Sections of the strata at Canajoharie and Spraker's Basin are presented and make an interesting comparison. Section along creek entering the Mohawk river at Canajo- harie, N. At Canajoharie the Calciferous is comparatively thin, bringing up underlying beds of limestone as shown in this section. IJpon the undulating and worn surface of the Calciferous there is a very thin bed (1-3) of Trenton limestone without any intervening *The significance of the artificial struct
