[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.

The latitude, by the mean of several observed
meridian altitudes of the sun, 53 deg. 5’ 0”
By the mean of 20 sets \
of lunar observations, } 193 47 45
/ with the sun east of the }
The longitude { moon /
\By the mean of 14 sets, \
with the sun and stars } 193 11 45
west of the moon /
The mean of these 193 29 45
The longitude assumed 193 30 0

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

  By King George’s (or Nootka) Sound rate,
   12^h 56^m 40^s, 4 194 10 6

  The 30th of June, the time-keeper, by the
   same rate, gave 193 12 0

  The error of the time-keeper, at that time,
   was 0 18 0 W.

  At this time, its error was 0 39 54 E.

  The error of the time-keeper, between our
   leaving Samganoodha, and our return to
   it again, was 0 57 54

  On the 12th of October, the variation A.M. 20 deg. 17’ 2"\ Mean 19 deg. 59’
  By the mean of three compasses, \P.M. 19 41’ 27
15” East.

  Dip of the needle / Unmarked end \Dipping, 68 deg. 45’\ Face 69 deg. 30’
                    \ Marked end / face East \69 55 / West \ 69 17

  Mean of the dip of the north end of the needle 62 deg. 23’ 30”.
