they are put together, and are properly fitted, stored, and victualled, you are to dispatch one or both of them, under the care of proper officers, with a sufficient number of petty officers, men, and boats, in order to attempt the said passage, with such instructions for their rejoining you, if they should fail, or for their farther proceedings, if they should succeed in the attempt, as you shall judge most proper.  But, nevertheless, if you shall find it more eligible to pursue any other measures than those above pointed out, in order to make a discovery of the beforementioned passage, (if any such there be,) you are at liberty, and we leave it to your discretion, to pursue such measures accordingly.

In case you shall be satisfied that there is no passage through to the above-mentioned bays, sufficient for the purposes of navigation, you are, at the proper season of the year, to repair to the port of St Peter and St Paul in Kamtschatka, or wherever else you shall judge more proper, in order to refresh your people and pass the winter; and, in the spring of the ensuing year 1778 to proceed from thence to the northward, as far as, in your prudence, you may think proper, in further search of a N.E. or N.W. passage from the Pacific Ocean into the Atlantic Ocean, or the North Sea; and if, from your own observation, or any information you may receive, there shall appear to be a probability of such a passage, you are to proceed as above directed:  and having discovered such passage, or failed in the attempt, make the best of your way back to England, by such route as you may think best for the improvement of geography and navigation, repairing to Spithead with both sloops, where they are to remain till further order.

At whatever places you may touch in the course of your voyage, where accurate observations of the nature hereafter mentioned have not already been made, you are, as far as your time will allow, very carefully to observe the true situation of such places, both in latitude and longitude; the variation of the needle; bearings of head-lands; height, direction, and course of the tides and currents; depths and soundings of the sea; shoals, rocks, &c.; and also to survey, make charts, and take views of such bays, harbours, and different parts of the coast, and to make such notations thereon as may be useful either to navigation or commerce.  You are also carefully to observe the nature of the soil, and the produce thereof; the animals and fowls that inhabit or frequent it; the fishes that are to be found in the rivers or upon the coast, and in what plenty; and, in case there are any peculiar to such places, to describe them as minutely, and to make as accurate drawings of them, as you can; and, if you find any metals, minerals, or valuable stones, or any extraneous fossils, you are to bring home specimens of each, as also of the seeds of such trees, shrubs, plants, fruits, and grains, peculiar to those places, as you may be able to collect, and to transmit them
