In every case first inclination (blue water) to about. 20-30 fathoms, then suddenly incline — (at mean angle of 45°?
from land to 1200 ∠ 36° — from the 20° fathom, 39° — from 270 to do 48° —
At mouth from the 5 fathom sounds to the 550 ft 24° — from the 20 to 550 21°
In the 1200 section 20 fathom 200 3d from shore
In othr or SW section 20 — 100 — — —
The scale of 1. inch mile (∴ sect 9. inch long) two line can barely be ruled so as to be distinguished apart, if head a few feet distant.
Cocos Isd 6 or 7 larger Isd — 23: 24 of all sorts besides with traces
Mem growing points with Cocoa nuts — growing trees
Keeling Isd 1. & 400 yds. without reef 1.300 yds width 1200 yds including reef
reef 100 yds — Blue water broadest on West side; on the northern part of which no reef but sand, & there 400 yds wide. — case like Horsburgh Isd — one single dip of land, opening dead to SE. —
Same struck of reef. Liesk.1 —
Line cut by rocky cliffs

Keeling Isd little to W of North, 14 miles distant
Cocos Isd
whole opposite side or northern. very imperfect. especially west. part weaker. —
The deeper part of northern basin, which does not dry, 4-6. fathoms. with numerous patches fluish. — & deeper holes
longer axis NNW. 9 & 1/2 miles: shorter 6 & 1/2: —
widest average parts 800 yds — leeward side perhaps broadest
Blue water 200 yds wide: do of hornblende 850 yd — width 6 & 7 fathoms
On East side. 100 yd reef from shore or West. 200 yd. —
On southern end. reef joins on the lagoon
Whole northern end shoal; connected with mouth.
[sketch] form of growing Isld
3 & 4 fathoms at entrance, 9 at anchorage
Reef at SE. houses. from do to outside (which is all outside reef) (550 yd): at houses & near anchorage 500 yd, inlets at anchorage begin to apear 250 yds from outer break.
