296 WITH SCOTT: THE SILVER LINING 



miles south ; and this saved a lot of trouble with the usual 

 " three-point resection " method. I climbed up the Ramp 

 and read " Bertram." I could see the sun shining on Inacces- 

 sible Isle, and even on Hut Point far to the south, but it 

 would need to get considerably higher before it illumined the 

 Ramp. Lieut. Evans was setting up signal flags on the 

 prominent debris-cones, and we returned together via 

 the " Slippery Slopes," Evans justifying the name ! 



" Just before I reached the Hut I felt exactly like Peter Pan, 

 and saw that I had regained my shadow ! I walked up to 

 Wind Vane Hill, and there was the old sun showing half his 

 disc over Cape Barne Glacier ! About 1 p.m. I went out with 

 the c mousetrap ' camera, and took some photos to celebrate 

 the event. I gave four seconds (with F. 45) on snow banks, 

 etc., lit by the low-lying sun. This was too much, I believe, 

 but the photos were fairly satisfactory and worth the trouble 

 considering when they were taken." 



Wilson reported some queer algae deposits above Gully 

 Bay, so we went off to investigate them. There were two 

 layers (about fifty feet above the glacieret) in the soft kenyte 

 gravel. I had little doubt that they were lake algae which 

 had grown when the water was held in by a larger ancestor of 

 the present glacieret. Just to the west were beautiful ex- 

 amples of these ice-dammed lakelets, with " Glenroy terraces " 

 marking various contours on their shores, just as in the 

 historic Glenroy region in Scotland. Only in these Antarctic 

 specimens the ice dams are still evident, whereas their absence 

 in Scotland made the origin of the Scotch terraces a puzzle for 

 many years. 



I have made frequent mention of the debris-cones on the 

 Ramp. Their origin was often discussed by Scott, Wilson, 

 Debenham, Wright, and myself. Scott and Wilson believed 

 they were dumped over at re-entrant angles in a bygone ice- 

 barrier wall. Debenham compared them to the cones and 

 hollows we had seen over in the western moraines and thought 

 they were due to the melting of submarine ice. Wright 

 and I believed them to be due to the weathering of huge 

 erratics. 



On the 27th Gran and I made the rather obvious test of 

 cutting one open. It was six feet high and lay just on the 

 edge of the steep slope of the Ramp, whence all debris would
