The first Demonstration, Where in Are described the south Sea, the Vliestreame, the Vlie, and the channell of Ameland.
WHen you saile from Am∣sterdam to the Fall of Vrck, you must keep the middle of the channell, in sailing to Tyoort, and from thence over Pam∣pus,* 1.1 with a shipp of great draught, that draweth tenne foot or more; keepe Marcken church without to the land of Udam, called Schytel∣doecks-haven, so long untill that the steeple of Zuyder∣wouw come past Kinnigherbuert, which are the houses half way betwixt Schyteldoecks-haven & Durgerdam, goe then towards the land e. untill that the New church of Amsterdam come about Durgerdam, keepe that so standing, untill that the church of Weesp be come past the House or Castle at Muyen, so that it do stand some∣what nearer to Muyen then to the House, keepe Weesp standing so, untill that Edam come without the east end of Marken. In this farewaye it is a foote deeper, then if you sailed right through.
For to avoyde Muyen sand: men were wont to bring the houses which were wont to stand upon Tyoort to the southwards of the Heyligher-stee at Amsterdam, thereby you may make some reckoning, they are good longst markes: when Monnickedam is about the west end of Schyteldoecks-haven, and the house at Muyen betwixt Weesp and the church at Muyen, then are you thwart of Muyen sand. For to saile right through over Pampus, then keepe the steeple of Diemen over or a∣bout the point of Tyoort, so long as you can see Tyoort, that is a right longst marke for to saile over Pampus.
When you are come thwart of the east end of Mar∣ken, goe then on northeast, or somewhat more east∣wardly towards the Fall of Urck, which is 7 leagues: when you are come with in a great league of Urck, you shall meete with a hard sand,* 1.2 called the Houtribbe, lying southeast and northwest thwart over the Farewaye, there is no more water upon it, then upon the Flat of Wieringen, or of Freesland, you shall finde alsoo no deeper water there then eight through. When Enckhuy∣sen lyeth northwest & northwest and by west from you, then you are upon the Houtribbe. Before that you come against the sand, you can by night see the fire upon Urck. When as Urck or the fire is more northerly then northeast from you, and that you get shoaling, then that is certainly of the Houtribbe: for so you can∣not come too neare the Enckhuysen sand. When you come from the southwards, you are not about the Enck∣huysen sand before that the church upon Urck come without the little village of houses, which is then east and by south, and east southeast from you: if that then you goe away northwest and by west or westnorthwest you shall runne close alongst by the side of the sand. With a ship of great draught, bring the church a good way through the houses, untill that it stand eastsouth∣east from you, then goe bouldly on northwest and by west or keepe Medenblick without the point of the Ven, and so you shal not come too near neither to sand nor shoale. Likewise if you come from the northwards, and bring Urck not more eastwardly then eastsoutheast from you,* 1.3 then you cannot take hurt also of the Enck∣huysen sand. From Urck to the buyes upon the Cripple and Hof-stede, the course is northwest and by west with that course you may runne all alongst unto the souther buye upon Wieringhe•• Flat: in turning to wind∣wards, you may well bring Medenblick a little within the point of the Ven, but when as Medenblick is without it, then you are in the right fareway.
Betwixt Urck and the buye upon the Hofstede north∣east somewhat eastwardly from the steeple of Enckhuy∣sen lyeth a little plate of hard sand, lying towards the end of Enckhuysen sand, which is not deeper then the Frees Flat, about to the eastwards of it, is the deepest water, but about to the westwards of it (by some called the Katte-gar) you shall be sooner about the High horne, or the Enckhuysen sand, & it is good for ships that draw but little water.
The thwart markes of the buyes,* 1.4 both upon the Cripple and Hosstede; are Grootebroeck and Hem (two sharp steeples) right one in the other, and Warnis, a little sharp steeple in Freesland to the south side of the Cliffe of Staverne, then you have the length of these buyes, which lye each of them in three fathom, the one on the east shoare, and the other on
