Instructions and notes very necessary and needfull to be obserued in the purposed voyage for discouery of Cathay Eastwards, by Arthur Pet, and Charles Iackman: giuen by M. William Burrough. 1580.

When you come to Orfordnesse, if the winde doe serue you to goe a seabord the sands, doe you set off from thence, and note the time diligently of your being against the said Nesse, turning then your glasse, whereby you intende to keepe your continuall watch, and apoint such course as you shal thinke good, according as the wind serueth you: And from that time forwards continually (if your ship be lose, vnder saile, a hull or trie) do you at the end of euery 4 glasses at the least (except calme) sound with your dipsin lead, and note diligently what depth you finde, and also the ground. But if it happen by swiftnes of the shippes way, or otherwise, that you cannot get ground, yet note what depth you did proue, and could finde no ground (this note is to be obserued all your voyage, as well outwards as homewards.). But when you come vpon any coast, or doe finde any sholde banke in the sea, you are then to vse your leade oftener, as you shal thinke it requisite, noting diligently the order of your depth, and the deeping and sholding. And so likewise doe you note the depth into harboroughs, riuers, &c.

[Sidenote: How to note downe in his Iornall of the voyage, his dead reckoning, and other obseruations.] And in keeping your dead reckoning, it is very necessary that you doe note at the ende of euery foure glasses, what way the shippe hath made (by your best proofes to be vsed) and howe her way hath bene through the water, considering withall for the sagge [Footnote: i.e., Current.] of the sea, to leewards, accordingly as you shall finde it growen: and also to note the depth, and what things worth the noting happened in that time, with also the winde vpon what point you finde it then, and of what force or strength it is, and what sailes you beare.

But if you should omit to note those things at the end of euery foure glasses, I would not haue you to let it slip any longer time, then to note it diligently at the end of euery watch, or eight glasses at the farthest.

Doe you diligently obserue the latitude as often, and in as many places as you may possible, and also the variation of the Compasse (especially when you may bee at shoare vpon any land) noting the same obseruations truely, and the place and places where, and the time and times when you do the same.

[Sidenote: For noting the shape and view of the land at first discouery, &c.] When you come to haue sight of any coast or land whatsoeuer, doe you presently set the same with your sailing Compasse, howe it beares off you, noting your iudgement how farre you thinke it from you, drawing also the forme of it in your booke, howe it appeares vnto you, noting diligently how the highest or notablest part thereof beareth off you, and the extreames also in sight of the same land at both ends, distinguishing them by letters, A. B. C. &c. Afterwards when you haue sailed 1. 2. 3. or 4. glasses (at the most) noting diligently what way your barke hath made, and vpon what point of the Compasse, do you againe set that first land seene, or the parts thereof, that you first obserued, if you can well perceiue or discerne them, and likewise such other notable points or signes, vpon the land that you may then see, and could not perceiue at the first time, distinguishing it also by letters from the other, and drawing in your booke the shape of the same land, as it appeareth vnto you, and so the third time; &c.

And also in passing alongst by any and euery coast, doe you drawe the maner of biting in of euery Bay, and entrance of euery harborow or riuers mouth, with the lying out of euery point, or headland, (vnto the which you may giue apt names at your pleasure) and make some marke in drawing the forme and border of the same, where the high cliffs are, and where lowe land is, whether sande, hils, or woods, or whatsoeuer, not omitting to note any thing that may be sensible and apparant to you, which may serue to any good purpose. If you carefully with great heede and diligence, note the obseruations in your booke, as aforesaid, and afterwards make demonstration thereof in your plat, you shall thereby perceiue howe farre the land you first sawe, or the parts thereof obserued, was then from you, and consequently of all the rest: and also how farre the one part was from the other, and vpon what course or point of the Compasse the one lieth from the other.

[Sidenote: For obseruing of tides and curants.] And when you come vpon any coast where you find floods and ebs, doe you diligently note the time of the highest and lowest water in euery place, and the slake or still water of full sea, and lowe water, and also which way the flood doeth runne, how the tides doe set, how much water it hieth, and what force the tide hath to driue a ship in one houre, or in the whole tide, as neere as you can iudge it, and what difference in time you finde betwene the running of the flood, and the ebbe.
