If ever government should find it necessary to send ships to that country, which may be intended to return immediately from thence to England, I beg leave to suggest to your lordships, that the particular seasons in the southern hemisphere should be considered, in order to prevent those delays in the return of the ships which must inevitably attend their sailing at an unfavourable time.

If such ships leave England in February, or earlier, if found more convenient, they should refresh at Rio de Janeiro in preference to the Cape of Good Hope; as by the time they could arrive at the Cape the north-west winds will be setting in there, which will oblige them to go into the False bay; this will considerably encrease their expences, and probably occasion some delay:  sail immediately from Rio Janeiro for the coast of New South Wales, where, if they are not uncommonly unfortunate, they will arrive early in September; this is giving them good time.

They will then have time to clear, ballast, and to refresh their people for six weeks or two months, and return by Cape Horn; or, if the western passage be found preferable, the season will be equally favourable for it.  If they should take their route by Cape Horn, as they will no doubt require to refresh somewhere in their voyage home, they may either stop at Santa Catherina or Rio Janeiro, on the Brazil coast, or go to the Cape; in this case I would recommend the Cape, as more convenient, in more respects than one.  If they are sickly, there they may get a supply of men, which it is well known they cannot at either of the other places; and in sailing from the Cape homeward they will have the advantage of being to windward; however, if as late as April, they would probably prefer Brazil.  If water only were wanted, that could be had at Falkland’s Islands.

In taking the liberty to offer these hints, I mean only, that in order to prevent any loss of time, upon such a service, the ships may be dispatched from England in such time as to insure their having the Summer months to return either by Cape Horn, or the western route, as may be directed.

The ships upon this service will no doubt be under the inconvenience of coming upon the coast of New South Wales in some of the Winter months; we have some bad weather on that coast in the Winter, and some smart gales of wind; the easteriy gales always bring thick or hazy weather:  I would recommend the not making too free with the coast, until they be near the parallel of their port.  In steering in for Port Jackson, if they should fall to leeward, either with a northerly or southerly wind, they can avail themselves of either Botany-Bay or Broken-Bay, Port Jackson being the center harbour.

In the sketches which will accompany the narrative of my last passage, I beg leave to inform your lordships, that the bearings and relative situations of the different lands which we fell in with were determined by intersections taken from the ship by Lieutenants William Bradley and Henry Waterhouse, who paid particular and constant attention to those very necessary observations; and that the situations of the lands in general were determined by observations for the longitude as well as latitude, which were made by myself and the above officers.
