Windor, Ama doria, July 2-1912 Started into measure in detail the Windon section out Dr. Jose E. Hyde. Began at the iron bridge over the Avon. The section begins at the top of the eastern limb and goes down to center yard. (1) At the bridge at low tide one sees considerable brick red shales with streaks of green gneiss that measure 60 feet across the strike. To all seem. These are the higher beds and we nearest the bridge. Thickness to be calculated from the dip which is roughly 80° N.N.E. No fossils. Calculate thickness. (2) Across the strike this gneiss is 3 feet of soft brecciated im- fused dark greenish dolomite terminating below in 6 inches of dark- blue-green shales. No fossils. Dip about 40° (3) Brick-red shales with two or three thin zones of the same brecciated rotten dolomite, in the lower half passing upwards into the greenish flaggy beds of division (2). Measurement across the strike about 31 feet. Dip 35° N.N.E. (4) Thin bedded light green dolomitic limestones on that frail; 9 foot across strike. Dip about 30°. Strike (N. 77° W. magnetic abundance of (5) Ordovica praelii gneiss Ostracoda. Somewhat heavier bedded dolomitic limestone that weathers light yellowish. This bed is easily picked out from the flatty green beds above and the down rotten dolomite. Actual thickness from 18 to 30 inches, bedded (6) Gneiss of yellowish very soft cavernous dolomite. The small caverns were originally porous parts of fossils
