well stratified rocks we observe their strike and 

 dip near the head of the gorge. The former 

 measures W. 45° S. magnetic, and the latter 25° 

 northwest. Some pebbles are gathered to show 

 the varied colors and the clear crystalline habit 

 of the rock and one starts on the return to the 

 Station. 



Working one's way down through the almost 

 impenetrable salal from the rude trail to the 

 shore, little change is found in the character of 

 the rock. Toward the west are several deeply 

 cut ravines where streams have worn trenches 

 to the strait. These are crossed with difficulty, 

 because the resistant nature of the siliceous shale 

 to weathering and wave wear produces vertical 

 walls. Now and then a shaly condition of the 

 rocks alternates with quite massive beds. We 

 soon learn to distinguish these relations in the 

 surface contour of the rock; where projecting 

 masses stand up against the waves there is found 

 a hard and crystalline layer quite like the walls 

 of Providence Cove. At Kirkpatrick's we again 

 measure strike and dip. The former is W. 10° 

 S. and the latter 25° northwest. Many minor
