it these northern regions, with a few particulars
relative to the tides and currents upon the coast, and an account of
the astronomical observations made by us in Samganoodha harbour.
The tide is no where considerable but in the great river.[24]
[Footnote 24: Cook's River.]
The flood comes from the south or south-east, every where following
the direction of the coast to the north-westward. Between Norton
Sound and Cape Prince of Wales, we found a current setting to the
north-west, particularly off the cape and within Sledge Island. But
this current extended only a little way from the coast, nor was it
either consistent or uniform. To the north of Cape Prince of Wales,
we found neither tide nor current, either on the American or on the
Asiatic coast, though several times looked for. This gave rise to an
opinion entertained by some on board our ships, that the two coasts
were connected, either by land or by ice; which opinion received some
strength, by our never having any hollow waves from the north, and by
our seeing ice almost the whole way across.
The following are the results of the several observations made ashore,
during our stay in the harbour of Samganoodha.

By the mean of equal altitudes of the sun,
taken on the 12th, 14th, 17th, and 21st,
the time-keeper was found to be losing
on mean time 8", 8 each day; and, on
the last of these days, was too slow for
mean time 13^h 46^m 43^s, 98. Hence the
time-keeper must have been too slow on
the 4th, the day after our arrival, by 13^h
44^m 26^s, 62; and the longitude, by Greenwich
rate, will be 13^h 23^m 53^s, 8 200 58 27
