Longitude by twenty-five set of distances (sun West of first quarter of the moon) containing one hundred and seventeen sights, with the sextant:  144 degrees 52 minutes 16 seconds.

Longitude by thirty set of distances (sun East of first quarter of the moon) containing one hundred and fifty sights, with the sextant:  145 degrees 29 minutes 23 seconds.

Mean, of fifty-five sets:  145 degrees 10 minutes 49 seconds.)

The entrance is formed on the south side by a steep hill, covered with trees growing to the edge of its rocky shore.  The north side of the entrance is a low sandy beach of two miles and a quarter in length:  at its north end a range of hills rises abruptly, and extends for six or seven miles, when it again suddenly terminates, and is separated from the rocky projection of Cape Bedford by a low plain of sand.

The entrance of Endeavour River is defended by a bar, on which, at high water, there is about fourteen feet; but, at low water, not more than ten feet:  the channel over the bar is close to the south side, for the sandbank extends from the low sandy north shore to within one hundred and forty yards of the south shore, and at three quarters ebb (spring tides) is dry.

In steering in for the mouth, upon bringing Point Monkhouse in a line with Point a (the north point of the bay under Mount Cook) you will be in three fathoms; steer in until the south extremity of the low north sandy point is opened of the trend round Point c, when you may haul a little more in, and when point d (which is a point where the mangroves commence) bears South 33 degrees West (magnetic) steer directly for it; this will carry you over the deepest part or the bar, which stretches off from point c in a North 75 degrees West (magnetic) direction; another mark is to keep the trend beyond d just in sight, but not open, or you will be too near the spit:  the best way is, having opened it, haul in a little to the southward, and shut it in again:  you may pass within ten yards of point d; and the best anchorage is just within it; the vessel may be secured head and stern to trees on the beach, with bow and stern anchors to steady her.  No vessel of a greater draught than twelve feet should enter the harbour; and this vessel may even moor in four fathoms within her own length of the shore, with the outer trend just shut in by the mangrove point a.  The watering-place is a stream that empties itself into the port through the mangroves, about two hundred yards to the south:  and if this should fail, there is a good stream at the north end of the long north sandy beach.  The latter, although very high coloured, is of wholesome quality; but in bad weather is inconvenient to be procured on account of the surf.  Water for common purposes of cooking may be had on a sandy beach a little without the entrance, but it is of a mineral quality, and of brackish taste.  It is high water at full and change at eight o’clock, and the tide rises from five to ten feet.  The variation of the observatory was 5 degrees 14 minutes East.
