To enter it, pass in mid-channel, if anything, borrowing upon Point Escarpee, and steer for the Mondrain de Direction, and pass over the bar without fearing the breakers upon it, which are caused by the sudden decrease of depth, from twenty-two to six fathoms; after this the depth will continue without altering more than one fathom.

The best anchorage is to the South-West of Cape Ransonnet, for within it the passage is blocked up by shoals, over which a boat cannot without difficulty pass.
USELESS HARBOUR is so shoal as to be, according to its name, quite unserviceable; since boats can with difficulty penetrate to the bottom, although its length is twenty-one miles: HENRY FREYCINET HARBOUR is twenty-two leagues long in a South-East direction; and from three to six leagues wide.

Its entrance is blocked up by a bar; and, although the depth within is in some parts considerable, it is very doubtful whether ships can enter it.

The shores are difficult to land upon, from the shoals extending so far off.
On the western side of this harbour there are several inlets and deep bays, but too shoal to be of any service.

The eastern shore of the harbour is formed by PERON'S PENINSULA, which separates it from HAMELIN'S HARBOUR.
