A   VOYAGE    TO
1777. when the clouds about the fun difperfed long enough to

In the afternoon, the boats and turtling party, at the

a feaman belonging to the Difcovery, who had been miffing
two days. There were two of them at firft, who had loft
their way; but difagreemg about the mofl probable track to
bring them back to their companions, they had feparated;
