 on the N W. S1 de with heavy buttresses, and beyond four terraces come in sight (Fig IB) 

 The strata here are nearly horizontal dipping under the Straits at a very slight angle ' At 

 the eastward termination of the formation are again seen five very regular terraces (Fio- ]

 five terraces are very distinctly marked, the second of which is the highest; and ther

In Chateau Bay and Henley Harbor are some fine examples of ancient sea margins 

 They occur m recesses m the shore winch have been sheltered from the denuding agency 

 of the waves and strong arctic currents, which have swept around this bend in fhe coal 

 with great power. The most plainly marked example forms the eastern shore of Henley 

 Harbor being the western shore of Henley Island. This beach, which is 180 feet hi'h 

 above the water level, u composed of three well-marked terraces, which become set 

 as we go from the bottom to the top. The upper terrace begins at the base of the basalt 

 columns capping this island, and is covered at its upper edge with the debris from th 

 mass of trap. The two lower terraces at the northern end of the island present a dXike 

 expansion facing the northwest. On these terraces, which are destitute of the usual coe it 

 of moss and Empetrum, can be most distinctly seen the windrows of pebbles and g I el
