Hence to CAPE DON is three miles and a half.

The latter cape is in latitude 11 degrees 19 minutes 30 seconds, and longitude 131 degrees 45 minutes 30 seconds.
VAN DIEMEN'S GULF is seventy miles deep, and more than forty broad.

It has two outlets to sea; the one to the northward, DUNDAS STRAIT, is sixteen miles wide and very deep; the other, CLARENCE STRAIT, is seventeen miles wide, and communicates with the sea round the south sides of Melville and Bathurst Islands: it is probably not so safe as Dundas' Strait, on account of Vernon's Isles, which lie in mid channel, near its western end.
The north eastern side of Van Diemen's Gulf washes the south side of Coburg Peninsula.

It has several bays, and, to the eastward of MOUNTS BEDWELL and Roe, the shore is fronted by SIR GEORGE HOPE'S ISLANDS, forming a channel or port within them twenty miles deep and from three to six broad; the entrance to it is round the north end of GREENHILL ISLAND, which is separated from the land of the peninsula, by a strait a mile and a half wide: the depth in mid-channel, for the shore on either side for half a mile is shoal and rocky, is eighteen fathoms, and within it the bottom is six, seven, and eight fathoms deep, and principally of mud.
This strait is in latitude 11 degrees 35 minutes.
The eastern side has several openings in it, but the shores are very low, and of shoal approach.

At its south-east end are the two (and probably three) Alligator Rivers; the westernmost (or centre) is fronted by FIELD ISLAND, the centre of which is in 12 degrees 6 minutes latitude, and 132 degrees 25 minutes 10 seconds longitude.
