July 22, Monday. Mistle Head, Started with James' launch at 8.30 for Burnt nira and got 9 miles Jim Curley by 10.30. Then walked east one mile to mile post 376. Are dwell about here to the east for some miles in a sandy highly micaceous schist and apparently The cryol mine even longer into north. and apparent overlaid with py and red cry olomates. The thickness must be very great. The granite is mil in eight mn even as folding in the stream. It may be ten miles further along the railway to the granite. Duncan visited the schist in Stady for 3 miles The "Limestone Quarry" begins at about 397 1/2 miles and continues For further descript see page 67. along the humber (along the strike) for about one mile. I learn the strike Duncan estimates the thickness at 1500 feet but it may be twice as thick as only to the crest of the mountain. He measured these magnesian limestone practically stand on end and have a strike 1 They in more than one mile there is schist These schists are not so much metamorphosed further east and are different in character, crit with an estimated thickness 1 mi far from me miles. At the main station on the schist series there is a thin-edged blue chalk limestone that in many ways reminds of Ordovician (Redmanation) in its surface weathering effects. (See the sample). Further down streams this is another thick mass of the same kind of delomite and offrite on another side of the humber the contact between the delomites and schist is once shown on the face of the mountain. From here with me estimated the thickness up to the center of the syncline as about 3700 feet thick. From due north to the nine north all in the same and in the air very normal delomites of the western limb of the syncline. These strata end with their north. edges sharply along the strike and make a precipitous mountain face trending and about 1/2 mile across the strike from the lark granite extreme. At mile post 401 along the railway but far better along the slope may be seen several hundred feet of a pinkish and grey thin and thick bedded delomite in magnesian limestone. The dip of these strata is from first decline's shown along the rim, 58 N. 750 W. The exposed stratigraph for 150 yards = 378 feet of thickness. along the rim the dip is 65 N. 85 W.
