Observations made at the Sandwich Islands, on the Longitude, Variation of the Compass and Tides.—­Prosecution of the Voyage.—­Remarks on the Mildness of the Weather, as far as the Latitude 44 deg.  North.—­Paucity of Sea Birds, in the Northern Hemisphere.—­Small Sea Animals described.—­Arrival on the Coast of America.—­Appearance of the Country.—­Unfavourable Winds and boisterous Weather.—­Remarks on Martin de Aguilar’s River, and Juan de Fuca’s pretended Strait.—­An Inlet discovered, where the Ships anchor.—­Behaviour of the Natives.

After the Discovery had joined us, we stood away to the northward, close hauled, with a gentle gale from the east; and nothing occurring, in this situation, worthy of a place in my narrative, the reader will permit me to insert here the nautical observations which I had opportunities of making relative to the islands we had left; and which we had been fortunate enough to add to the geography of this part of the Pacific Ocean.

The longitude of the Sandwich Islands was determined by seventy-two sets of lunar observations; some of which were made while we were at anchor in the road of Wymoa; others before we arrived, and after we left it, and reduced to it by the watch or time-keeper.  By the mean result of these observations, the longitude of the road is

200 deg. 13’  0” East. 
Time-keeper / Greenwich rate,             200 deg.  0’  0”
\ Ulietea rate,               200 deg. 21’  0”
The latitude of the road, by the   \
mean of two meridian observations }      21 deg. 56’ 15” North.
of the sun                       /

The observations for the variation of the compass did not agree very well among themselves.  It is true, they were not all made exactly in the same spot.  The different situations, however, could make very little difference.  But the whole will be seen, by casting an eye on the following table.
