APPENDIX T he following appendix comprises a random sampling of sur viving documents related to Halley's three voyages. They in clude journal entries from his voyages, correspondence between Halley and the Secretary of the Navy Burchett, lords letters to the Navy Board, treasury papers, and Navy Board minutes, as well as the text of his description that accompanied some publications of his first sea chart.

In the afternoone we made the Iseland about 6 Leagues off us; bearing SWBW: The next day we came to an Anchor under the Lee of the Island, having narrowly escaped a Sunk Rock; that lies off the Sw point of the Island. I went on Shore to see what the Iseland might afford us, but found nothing but Small Turtle Doves and Land Crabbs in abundance, neither Goats nor hogs nor any people; we saw many green Turtle in the Sea and in Someplaces their Tracks on the Sand, but could Catch none, by reason of the great Surf of the Sea; we searcht the whole Lee Side of the Iseland but found no fresh water; we lookt not on the windward side because we found such a Suff on the Lee side; here we againe scrubb'd our Shipp and

Twas the last of November before we left the coast of England, wch considering the uncertainty of the Winds was I find above two months too late; but I hope to be in England time enough to proceed again this year if their Lordships shall think fitting to allow it. We watred in the river of Paraiba in Brasile here the Governour Dom Manuel Soarez Albergaria was very obliging and civill, but the Portuguez, as farr as I could guess, were very willing to find pretences to seize us and tempted us severall times to meddle with a sort of wood they call Poo de Brasile which is an excellent dye, but prohibited to all foreigners under pain of confiscation of Shipp and goods.

the same inconvenience of being late might attend me in case their Lordships, as I humbly hope, do please that I proceed again for I find it will be absolutely necessary for me to be clear of the Channell by the end of August or at farthest by the middle of September. But a further Lieutenant, who, because perhaps I have not the whole Sea Directory

I take it that he envys me my command and conveniences on bord, disdaining to be under one that has not served in the fleet as long as himself, but however it be I am sure their Lordships will think this intolerable usage, from one who ought to be as my right hand, and by his example my Warrant Officers have not used me much Better; so that if I may hope to proceed again I must entreat their Lordships to give me others in their room. Notwithstanding that I have defeated in my main design of discovery, yet I have found out such circonstances in relation to the Variation of the Compass, and the method of observing the Longitude at Sea (which I have severall times practiced on board with good success)

The greate hight of them made us conclude them land, but there was no appearance of any tree or green thing on them, but the Cliffs as well as the topps were very white, our people called A by the Name of Beachy head, which it resembled in form and colour, and the Island B in all respects was very like the land of the North-foreland in Kent, and was as least as hight and not less than five Miles in Front, The Cliffs, of it were full of Blackish Streaks which seemed like a fleet

Southwell; About taking the Survey of a Coast Honourd Sr. In obedience to your Commands I have endeavored to draw up such plain directions for making the Survey of a Coast, as may be serviceable to any that have the will and opportunity to describe curiously any Shoals they are acquainted with; In order to this Survey of a Sea coast and to lay down truly the shoals and dangers near it, if the land be accessible the best way will be to take with all possible care the true positions of as many remarkable objects such as Steeples, Mills, Rocks, Cliffs, Promontorys, or such like as you find most conspicuous along the coast, that is their true barings from one another in respect of the true North and South; which is best done by measuring the angle with any proper instrumt.
|
From page 205... ...
This done you may readily plot down all those objects on the Land, by any view of them from a vessell riding at Anchor off at Sea; for if you take their true position from your ship, by help of the rising or setting Sunn as before, the intersections of those lines with those of the positions of the objects to one another, will give you the places and proportionall distances of the sd Objects one from another, to which afterwards a scale may be adapted, as shall be taught by and by. Being thus assured of the plot of several objects on the shore, it will be very easy to lay down the points of any sand or shole, or any sunk rock on that Coast, either by the position of two or more of those objects, from a vessell riding at those points; or more compendiously and easily by taking the angles between those objects, at the said places entended to be laid down in your platt.

From page 206... ...
After your chart is made, you may adapt a scale to it, by help of the motion of Sound, which has been accurately tried both in England and France, and it is certain that sounds be they great or small move at the motion of Sound, which has been accurately tried both in England and France, and it is certain that sounds be they great or small move at the rate of a marine League in 15 seconds of time; and in still weather a gunn may be heard a great way, especially before a gentle gale of wind, and this I propose and recommend as a very usefull method of determining distances in these Hydrographicall Surveys. I shall be very willing further to explain any thing herin, that may obscure or difficult.

APPENDIX 207 Halley's description accompanying his Atlantic Chart. The Description and Uses Of a New and Correct SEA-CHART Of the Western and Southern OCEAN Showing the Variations of the COMPASS The projection of this Chart is what is commonly called Mercator's; but from its particular Use in Navigation, ought rather to be named the Nautical; as being the only true and sufficient C H A R T for the Sea.

From page 208... ...
As to the Uses of this Chart, they will easily be understood, especially by such as are acquainted with the Azimuth Compass, to be, to correct the Course of Ships at Sea; For if the Variation of the Compass be not allowed, all Reckonings must be so far erroneous; And in continued Cloudy Weather, or where the mariner is not provided to observe this Variation duly, the Chart will readily shew him what Allowances he must make for the Dfault of his Compass, and thereby rectify his Journal. But this Correction of the Course is in no case so necessary as in running down on a Parallel East or West to hit a Port; For if being in you latitude at the Distance of 70 or 80 Leagues, you allow tot the Variation, but steer East or West by Compass, you shall fall to the
|
From page 209... ...
The Rule to apply it is, That to keep your Parallel truly, you go so many Degrees to the Southward of the East, and Northward of the West, as in the West Variation; but contrariwise, so many Degrees to the Northwards of the East, and Southwards of the West, as there is East Variation. A further Use is in many Cases to estimate the Longitude at Sea thereby; for where the Curves run nearly North and South, and are thick together, as about Cape Bona Esperance, it give a very good Indication of the Distance of the Land to Ships come from far; for there the Variation alters a Degree to each two Degrees of Longitude nearly; as may be seen in the Chart.

210 HALLEY'S QUEST I shall need to say no more about it, but let it command it self, and all knowing Mariners are desired to lend their Assistance and Informations, towards the perfecting of this useful Work. And if by undoubted Observations it be found in any Part defective, the Notes of it will be received with all grateful Acknowledgement, and the Chart corrected accordingly.
