STONY RIDGES. 
miles from our camp we ascended some high ridges 
of an oolitic limestone formation, which were par- 
tially covered by drift-sand, and in the distance 
looked like the ridge of a sea shore. From their 
summit Cape le Grand bore E. 27° S., the peak 
called by the French the “ Chapeau,” E. 23° S., and 
the head of the salt-water lake E. 10° S. We had 
now a succession of barren, sandy and stony ridges for 
more than three miles, and as there was but little pros-

centres were set at S. 10° W., S. 26° W., E. 41° S., 
E.44° S. and S. 33° E. respectively ; the west point 
of a bay bore S. 51° W. the eastern point E. 36° S.

June 20. — Rain fell lightly but steadily until one 
p.m., making it very disagreeable travelling through 
the rugged and stony ridges we had to encounter, 
and which were a good deal covered with scrub and 
brush. About four miles from our camp of last 
night we crossed high stony ridges, and immediately 
beyond came to some steep sand-drifts, among the 
hollows of which I dug for water, but at five feet 
was stopped by rock. The scrubby, hilly, and
