THE MBTAMORl'HIC ROCKS OF ADELIE LAND. 8TILLWELL. 219 



Fig. 4. View from the barrier ice cliffs near Cape Gray, showing various members 

 of the Way Archipelago. A large amount of heavy floe ice is visible. This ice had 

 iiccumulated between the islands of the Way Archipelago and broken out before the 

 arrival of the sledge party on December 16th, 1912. 



PLATE XXV. 



Fig. 1. View from the eastern side of the Cape Gray Promontory, looking north- 

 east out of Watt Bay. Four individuals of the Way Archipelago can be seen, including 

 a very curious, wedge-shaped island. 



Fig. 2. Crumpled gneiss at the Cape Pigeon Rocks. 



Fig. 3. View from Garnet Point, looking north-east out of Watt Bay. A steeply 

 conical member of the Way Archipelago can be seen. Penguins are inspecting a mitten 

 in the foreground. 



Fig. 4. The steep descent to Garnet Point. An ice ramp enabled the sledge party 

 to descend from the top of the barrier cliff down to the rock exposure. 



PLATE XXVI. 



Figs. 1 and 2. These are two views showing the large aggregates of garnet and biotite 

 in the garnet felspar gneiss at Garnet Point. The ice axe, in Fig. 1, is 36in. long, lO^in.

Fig. 1 . The large recrystallised basic dyke cutting the garnet gneiss on the northern 

 part of the Cape Pigeon Rocks. An offshoot can be seen in the photograph. Specimen 

 No. 767 was collected from the large dyke. 



Fig. 2. A recrystallised basic dyke at Cape Gray. It cuts the garnet cordierite 

 gneiss and a fine stringer can be seen branching out into the gneiss on the right hand side.
