This is a strange alteration and very apt to deceiue the Sailer, vnlesse hee know the vnconstancie and variation of the Compasse, and take the eleuation of the pole sometimes with his instruments. If master Arthur be not well prouided in this behalfe, or of such dexteritie, that perceiuing the errour he be not able to correct the same, I feare lest in wandering vp and downe he lose his time, and be ouertaken with the ice in the midst of the enterprise. For that gulfe, as they say, is frozen euery yere very hard. Which if it be so, the best counsel I could giue for their best safetie, were to seeke some harborough in that baie, and those riuers whereof I haue spoken, and by some Ambassador to make friendship and acquaintance with the great Can, in name of the Queenes maiestie, which I beleeue will be gratefull to the mightiest Emperour in the world, yea most excellent for the length of the traffique, and great distance of the places. [Sidenote: The mouthes of Bautisus and Oechardus 300. leagues from Cambalu.] I thinke from the mouthes of the mighty riuers Bautisus and Oechardus to Cambalu the chiefest seat of the prince the Can, there are not past 300. Germaine miles, and to passe by Ezina a citie of the kingdom of Tangut, which seemeth to be but 100. Germaine miles from the mouthes of the sayd riuers, and is subiect to the great Can. I would gladly know how high the sea doeth flowe commonly in the port of Moscouia where your men do harborow, and in other Easterly places vnto Tabin. [Sidenote: Vpon the obseruations of the tides depend great speculations.] And also whether the sea in this streight do flow alwaies one way to the East or to the West, or whether it do ebbe and flow according to the matter of the tides in the middle of the chanel, that is to say, whether it flow there sixe houres into the West, and as many backe againe to the East, for hereupon depend other speculations of importance. I would wish M. Frobisher to obserue the same Westwards. Concerning the gulfe of Merosro and Canada, and new France which are in my mappes, they were taken out of a certaine sea card drawn by a certaine priest out of the description of a Frenchman, a Pilot very skilfull in those partes, and presented to the worthy Prince George of Austria, bishop of Liege: for the trending of the coast, and the eleuation of the pole, I doubt not but they are very neere the trueth: For the Charte had beside a scale of degrees of latitude passing through the middest of it, another particularly annexed to the coast of New France, wherewith the errour of the latitudes committed by reason of the variation of the compasse might be corrected. The historie of the voyage of Iacobus Cnoyen Buschoducensis throughout al Asia, Affrica, and the North, was lent me in time past by a friend of mine at Antwerpe. After I had vsed it, I restored it againe: after many yeeres I required it againe of my friend, but hee had forgotten of whom hee had borrowed it. The
