(d). The normal strike of N. 75° E. is abruptly rounded via a little cutting of a purfuzzy layer in the shingle below high tide (= d of section), Beyond which for 175 ft. there is a covered interval and the next beds cropping out have the normal strike of N. 70-80° E. (c). These beds begin near the base with a massive (?) stratum of coarsely crystalline rock which was originally mistaken for limestone owing to its beautiful & distinct stratification, the stone effervesces under acid, and this partly interest- ing appearance in the appropriate the rock is really a granite (the strong resemblance to which was noted in the field. When the rock was called limestone). Two feet of this granite sill are exposed, the lower limit unknown but the sill cannot be more than 10 feet altogether since it is very steeply crop out about 5 feet below the base. This granite is 1075- shales granite sill B granite sill The relations of the granite contain a 12 ft. rhyolite dike) and the dykote are illust- nated in the sketch. At the foot of the cliff of shales rhyolite dike there is a single beach, and the granite sill comes up through the shingle directly in front of and cutting across the path of the rhyolite dike, a few rods to the northeast. However, at the point B there is a little fault and displacement in the granite sill, the fault area is under 5' as marked by a crumpling of the shale in the cliff. But the shingle, rhyolite boulders are common but no more so than anywhere else along the beach. To the east of the faulted area the granite sill has very few calcareous layers which do not appear on the next led where place must have been in the gravel trench between the cliff & granite sill. The suggestion that the rhyolite came up through B, and moves between here & the dike as a sill in the beach cannot hold, because this plane is the beach is largely if not entirely filled by the calcareous layers. Hence the cutting of the granite sill across the rhyolite dike, we real proves the granite younger than the rhyolite. The rhyolite is 1078. (Continued p.17)
