survey or chart is especially interesting for a number of reasons:
First of all, the hydrographical information is very well detailed and
is accompanied by some excellent notes on the best channels and passages
through the islands. The notes specify where the best anchorages are
and even offer a guide as to what may be expected in certain places;
'In the passages and also in Drakes Channel the Current running quick
over foul ground causes a Ripple which wears the appearance of danger..'
. The chart contains several remarks at places where ships have
previously struck upon rocks and also where there are sunken rocks which
offer a hidden danger. The safest channels are similarly marked; 'the
round Rock passage is by far the best, Vessels bound to the Northward but
hauling up under the Dog Islands are at once clear of everything'.
