which two or three foot is a fliff gravelly Clay^then Marie. Thofefhat 
make Wells for frefh Water, if they find Springs in the Marie, they are 
generally frefh, but ifthey link through theMarle.they come to a whitifli 
Clay mixed withGravel ,in which the Springs are more or lefs brackifh. 
^^r.5.How firong the Water is of Salt ? and what quantity of Brine 
the Pits yeild ? 
Anfw, In the great Pit at Vprnch, we have at one and the fame time 
three forts of Brine, which we call by the names of Firft-man,Middle- 
man,and Laft-man, thefe forts are of different ftrengths > The Brine 
is drawn by Pump^ for that which is in the bottom is firft pumped 
out, which is that we call firft man, &c. That I might make an exad 
trial of the ftrength^ I made me a quart that contained 24. ounces T.'roy, 
of diftilled watef^ which quart being filled with the firft Brine befidc.^ 
the tare of the quart weighed 2^. ounces, v/hlch made 7. ounces and 
3. drachms of Salt without any additipn » the next day I weighed the 
fame Salt again^and it weighed 7. ounces and 6. drachms,by which it ap- 
pears this Brine yields above a fourth part Salt> fo that 4 Tuns of Brine 
make above one Tun of Salt. The fame quart filled with Middle-man, 
which is the fecond fort of Brine, weighed 28. ounces, I alfo weighed a 
quart of Brine as it came immediately out of the Springs which weigh- 
ed 28. ounces and the third fort 27. ounces, fo that what the firft gets 
the laft loofeth, which doth precipitate as much in 24. hours as if it 
flood much longer time. 
The quantity of Brine that this Pit yields every 24. hours is as 
much as will make 450. Bufhels of Salt, which is drawn out twice or 
three times a day, for fo oft we ordinarily draw, and that as long as 
the Pump willgoe. 
In the beft Pit ztNeihermch^ quart of Brine weighs 28. ounces 
and a half, this Pit is 18. foot deep, and four foot broad, and yields as 
much Brine every 24. hours as makes about 40.BuQiels of Salt, there is 
but one Spring in the Pit that comes in 2. foot and 8. inches above the 
bottom^ 
The worft Pit at Netherxvich is of the fame breadth and depth as the 
former, a quart of Brine out of which weigheth 27. ounces and yields 
as much Brine dayly as makes about 30. buftielsof Salt ; in this Pit are 
three Springs,two in the bottomland one about two foot higher i thefc 
Pits arc within fix yards one of another* 
Thefe Pits are near the Brook^^ the great Pit on the North fide, and a- 
bout a quarter of a mile lower the two lefTer Pits on the South fide. 
S^uer, 6. Whether the Springs yield more or lefs Brine at one time 
than at another ? 
Anfw. In the great Pit I find little or no variation, either in quality or 
iirength of the Brine, but the Springs in the other Pits are augmented 
by much rain, and yield lefs Salt.
