thing, I have forgot, or related obscurely, give yourself only the trouble of advertising me of it, and in my next I will add or cleer it.

AAA. is the Sea.

II. the Entry, by which the Sea-water passes into BB.

BB. the first Receptacle; in which the Water is kept 20. inches deep;

CCC. the second Receptacle, where the Water maketh three turnings, as you fee, and is 10. inches deep.

22. the Opening, by which the first and second Receptacle have communication one with another.

EEF. the third Receptacle, which is properly called the Marish.

dddddd'. is a Channel very narrow, through which the Water must passe before it enters out of the second Receptacle into the third.

33. is the Opening, by which the Water runs out of the second into the third Receptacle.

The pricks, you see in the Water throughout the whole Scheme, doe mark the course and turnings, which the Water is forced to make before it comes to hhhhh, which are the places where the Salt is made.

hhhhh. are the Beds of the Marish, where the Salt is made; and in them the Water must not be above an inch and an half deep. Each of these Beds is 15 foot long and 14 foot large.

99999. are the little Channels between the Beds.

88888, are the Apertures, by which the Beds receive the Sea-water after many windings and turnings.

When it raines, the openings 22, 33. are stopp'd, to hinder the Water from running into the Marish mark't EEF. Unless it rain much, the rain-water doth little hurt to the Marish; and although it rain a day or a night, we doe not let the water which is in the Marish run out, the heat of the Sun sufficiently exhaling such Rain-water, if, for example it be not above an inch high. Only, if it have rain'd very plentifully that day, no Salt is drawn for the 3. or 4. next-following days, Butif
