July 8-1918 Quentin mine practically parallel to the strike. Felix ore is about seven acres and is divided into 2 parts by 2 small headlands. There has been considerable disturbance in this core. The eastern part has the structure of a syncline and is formed of the laminated series seen at Drum of Drum Core. In the middle part of the core the lower 40 feet of the laminated series is repeated by a fault running N.70 E. and dipping 70 S. 50 W. showing a distinct drag indicating that the west or hanging wall has gone down. "All the beds in this core show effects of metamorphism in them, the schiel is darker reddish than normal. [To John: whether this change appeared to be due to pressure fracturing my mind, and then the aerial status deposited the iron in the course of the process] "The laminated beds are here cut off by another fault run- ing N.70 E and dipping about 75 S.20 E, with a heavy drag and much fracturing of the footwall showing that the west wall has come up. This brings to view 50 feet of loose shales. These are dark and red and in bands 1/2 inch or so in thickness. The surfaces of these bands have a sort of metallic film and they are nearly covered with fine ridges little markings, mist mud cracks and ripples. "Below these layers and as traveling on to the outer edge of Felix Core is exposed about 120 feet of stiff brown shales con- sisting of reddish sandstone in thin beds alternating with some thinner bedded lagers. These are marked at various levels.
