"But if you should fail in finding a passage through either of the said bays, or by any other way, as the season of the year may render it unsafe for you to remain in high latitudes, you are to repair to the harbour of St Peter and St Paul, in Kamtschatka, in order to refresh your people, and to pass the winter. "But, nevertheless, if you find that you cannot procure the necessary refreshments at the said port, you are at liberty to go where you shall judge most proper; taking care, before you depart, to leave with the governor an account of your intended destination, to be delivered to me upon my arrival; and in the spring of the ensuing year, 1779, you are to repair back to the above-mentioned port, endeavouring to be there by the 10th of May, or sooner. "If, on your arrival, you receive no orders from, or account of me, so as to justify your pursuing any other measures than what are pointed out in the before-mentioned instructions, your future proceedings are to be governed by them. "You are also to comply with such parts of said instructions as have not been executed, and are not contrary to these orders. And in case of your inability, by sickness or otherwise, to carry these, and the instructions of their lordships into execution, you are to be careful to leave them with the next officer in command, who is hereby required to execute them in the best manner he can. "Given under my hand, on board the Resolution, at Ulietea, the 18th day of November 1777. "J. COOK. "To Captain Charles Clerke, Commander of his Majesty's Sloop the Discovery," While we lay moored to the shore we heeled and scrubbed both sides of the bottoms of the ships. At the same time we fixed some tin-plates under the binds, first taking off the old sheathing, and putting in a piece unfilled, over which the plates were nailed. These plates I had from the ingenious Mr Pelham, secretary to the commissioners for victualling his majesty's navy, with a view of trying whether tin would answer the same end as copper on the bottoms of ships.
