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.

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 Jun
