On the west side of CAPE GRAFTON is a bay, in the centre of which is an island. The bottom is very shoal, but good anchorage may be had with the cape bearing South-East Between CAPE GRAFTON and SNAPPER ISLAND, the centre of which is in latitude 16 degrees 17 minutes 35 seconds, and longitude 145 degrees 27 minutes 40 seconds, is TRINITY BAY; the shores of which were not very distinctly seen. At the south side, and about seven miles within the cape there is an opening that appeared to be extensive, and the mouth of a considerable stream, trending in between high ranges of land, in a direction towards Bellenden Ker's Range. In latitude 16 degrees 23 1/2 minutes, and longitude 145 degrees 34 minutes is a group consisting of three coral islands; which, being very low, are dangerous to pass in the night. The offing is said to be strewed with extensive reefs; we saw none beyond Green Island: those that are laid down on the chart are from Lieutenant Jeffrey's account.* (*Footnote. Much shoal water was seen to the northward of Green Island from the Tamar's masthead. Roe manuscript.) SNAPPER ISLAND lies off the point which forms the northern limit of Trinity Bay; it is small, and does not supply any water.* (*Footnote. Ten or eleven miles South 80 degrees East from Snapper Island is the north-west end of a shoal, extending to the South 41 degrees East for sixteen or seventeen miles; the Tamar anchored under it. Roe manuscript.) The land behind CAPE TRIBULATION may be seen at a greater distance than twenty leagues. It is here that the outer part of the barrier reefs approach the coast, and there is reason to believe that, in latitude 16 degrees 17 minutes 35 seconds, longitude 145 degrees 27 minutes 40 seconds, they are not more than twenty miles from it. The cape has a hillock at its extremity, and a small rocky islet close to the shore that renders it conspicuous: it is fourteen miles beyond Snapper Island. The shore appears to be bold to: at three miles off we had sixteen fathoms. Ten miles further to the northward is BLOMFIELD'S RIVULET in Weary Bay: it is blocked up by a rocky bar, having only four feet water over it; the anchorage off it is too much exposed to be safe. The river runs up for four or five miles, having soundings within it from three to four fathoms, its entrance is in 15 degrees 55 minutes 50 seconds. The coast then extends to the north to Endeavour River, and forms a few inconsiderable sinuosities; it is backed by high land, particularly abreast of the Hope Islands. These islands open of each other in a North 39 degrees East direction, and appear to be connected by a shoal; it is however very likely that a narrow passage may exist between them, but certainly not safe to sail through. Here the number of the coral reefs begin to increase, and great attention must be paid in navigating amongst them; but, with a careful look out from the masthead, and a quick leadsman in the chains, no danger need be apprehended.
