August 17. Harkes Bay, north shore more than shaly beds with layers of dark sandstone for foot. The clay argil, yellow weathering dolomite again for 5 feet. Then about 3 feet of pure sandstone again at the base of a sharp steeply plunging fold which has a direction of N.60° E., ke- yword and the dip of the beds is again northeast, dips 20 due E. The next exposure 100 yards further is of light gray fine grained lime sandstone in deep beds dipping 20 5.60°E at first, thick some erring by due E another 50 yards, a thickness of 60 feet in all, some of the layers are distinctly cross-bedded. Once of the sandstones is fine grained dense and quartzitic. The top 5 feet is thumbed and passes by easy gradation into thinly laminated shaly sandstone in which worm tubes are very thick. These tubes are one D shaped but a broad head. The filling of the hole is about 3/8 inch in diameter and 2 1/2 to 3 inches in length between the ends. A thickness of 6 feet of these shaly beds is exposed. Following a sharp undergrained internal line is 20 feet once of light gray limy bedded sandstones, succeeded by 5 feet of Harkes shale. Then a 3 foot bed of dense fine sandstone, then hopefully beds that are dark gray in color and weather into somewhat gritty layers an inch or thick by are dense and hard but very crisp. scratches a dull stone. The beds have many small particles of calcite. I think the rock is a dolomitic li, but Prof Johnsen thinks they caly sandstone,
