Another circumstance which prevents any precise instructions being given to you on this head, is the uncertainty that prevails here respecting the weather which you may at that period find in those latitudes, and which it is possible may be such as if not altogether to prevent the execution of these orders, may at least cause them to be ineffectually performed, or perhaps lead to a waste of time, which might be better employed on other parts of the coast.  If such should eventually be the case, it would be prudent not to attempt this intricate part of the coast during the prevalence of the north-west monsoon, but to employ it in completing the examination of Shark Bay and of Exmouth Gulf, as well as of other unexplored intervals of coast up to the 122nd degree of longitude; or, with a view to the proximity of one of the above-mentioned places of refreshment, it might, perhaps, be advisable, if compelled to quit the vicinity of Dampier Land, to devote that part of the season to a more careful investigation of the low shores of the gulf of Carpentaria, where it has been surmised, though very loosely, that rivers of some capacity will be found.

The above objects having been accomplished (in whatever order you may find suitable to the service) you will return to the southern settlements for refreshments; and then proceed, during the summer months of fine weather and long days, to Bass Strait, in which so many fatal accidents have recently occurred, and of which you are to make a correct and effectual survey.

But previous to your undertaking that survey, as it has been represented to us that it would be very desirable for the perfection of the Tidal theory, that an accurate register of the times and heights of high and low-water should be kept for some time in Bass Strait, you will (if practicable) establish a party for that purpose on King Island, and you are to cause the above particulars of the Tides there to be unintermittently and minutely observed, and registered in the blank forms which will be supplied to you by our Hydrographer.  If, however, circumstances should render this measure unadvisable at that island, you will either choose some less objectionable station, where the average tide in the Strait may be fairly registered; or, if you can employ no permanent party on this service, you will be the more exact in ascertaining the above particulars at every one of your stations; and in all parts of this Strait you will carefully note the set and strength of the stream at the intermediate hours between high and low-water, and also the time at which the stream turns in the offing.
