1. I have uniformly found it true, that the bottom causes the change in the color of the sea, and makes the color lighter or darker according as it may happen to be; as we experienced from the beginning to the end of our voyage. And this is the reason: the water of itself has no color, but, as it is transparent, the bottom shows itself, such as it is, through the clearness of the water, according to its depth; but something must be allowed for the sky, clouds and other bodies in the atmosphere, which, although they do not change the water, nevertheless shine in it, and throw a shadow or reflection.

2. The banks or shoals of Newfoundland extend further south than they are laid down on the charts, and as far as 36° or less of latitude, as we observed from the color of the water, although it may be deeper there than about Newfoundland.

3. There is a stream running from the river Amazon, in fact from Cape——, along the coast of Guiana, through the Gulf of Mexico and the channel of the Bahamas, along the coast of Florida, Virginia and New Netherland, to the banks of Newfoundland, where, uniting with another stream, coming from the north out of Davis's Strait and river St. Lawrence, it goes again south, and afterwards S.W., to the Bermudas, but mostly to the east of them, the particular causes and reasons of which we will notice in its proper place.

4. This stream has its course along the gulfs, capes and bays of the coast, the same as we experienced near or west of Cape Cod or Staten Hook, where for two days successively, without headway on the ship, and in a calm, we were carried by it a degree to the north. This should be kept in mind, and one should regulate himself accordingly.

5. The storm of the Bermudas has been mentioned in its place.[92]

6. I have heretofore exposed mistakes on the large plane chart, and it is not material to enter further into that subject.

7. After we approached and passed the Bermudas the wind did not turn round the compass with the sun, which happened to us four or five times, and frequently does so, as is said by experienced persons.

8. Therefore, in navigating this passage for this place, it is best, when there are no reasons to the contrary arising from the Turks[93] or otherwise, to run just above or below the Azores, to latitude 34 and 33, and even to 32 and 31, in order to get into the stream, and yet I also consider it well to sail to the eastward of these islands; or if you avoid the Azores, then to sail from Newfoundland or its latitude, due south, or S.S.E., to the before mentioned latitude; but, in returning, it is best to follow the coast to Newfoundland, in order to fall into the stream and wind. The home voyage is almost always the shortest, inasmuch as the stream runs mostly along the coast.

9. When a change occurs in the color of the water, and at other times, the deep lead should be much used. It should be of 25 or 30 pounds weight. The ship or vessel should lie as still as possible, or the jolly-boat should be used, whether the lead be thrown with a certainty as to where you may be, or for the discovery of other bottom.

10. In storms or hurricanes never be without stern-sails, however small, unless you can sail before the wind, but no longer than that; for it is too dangerous, and too uncomfortable, both for the ship and the persons in her.

Some other observations in regard to the art of navigation and the management of ships, of minor importance we will reserve for another occasion.
