Since the conclusion of Beering's voyage, which was made at the expense of the Crown, the prosecution of the new discoveries began by him has been almost entirely carried on by individuals. These persons were principally merchants of Irkutsk, Yakutsk, and other natives of Siberia, who formed themselves into small trading companies, and fitted out vessels at their joint expense.

Most of the vessels which are equipped for these expeditions are two masted: they are commonly built without iron, and in general so badly constructed, that it is wonderful how they can weather so stormy a sea. They are called in Russian, Skitiki, or sewed vessels, because the planks are sewed together with thongs of leather. Some few are built in the river of Kamtchatka; but they are for the most part constructed at the haven of Ochotsk. The largest of these vessels are manned with seventy men, and the smallest with forty. The crew generally consists of an equal number of Russians and Kamtchadals. The latter occasion a considerable saving, as their pay is small; they also resist, more easily than the former, the attacks of the scurvy. But Russian mariners are more enterprising and more to be depended upon in time of danger than the others; some, therefore, are unavoidably necessary.

The expenses of building and fitting out the vessels are very considerable; for their is nothing at Ochotsk but timber for their construction.
